Survive the AI Knife-Fight: Building Products That Win
Shared AI capabilities make products easier to build and harder to distinguish. Durable advantage starts with unmet needs, distinctive data, and functionality that compounds.
From a talk by Brian Balfour
When every product enters your category
Think back over just 45 days of AI product launches. In Brian Balfour’s opening retrospective, Notion moves into territory occupied by Granola, Glean, and ChatGPT; Figma expands toward Canva, Framer, Illustrator, and Lovable. A familiar product category no longer tells you who your competitors will be.
The overlap continues: Atlassian adds meeting notes, search, and Claude integrations; Anthropic expands into enterprise search and integrations; Google and OpenAI push further into coding. These are Balfour’s competitive interpretations of the launches surrounding the talk, with well-funded startups crowding the same categories.
Disruption can move just as quickly. Balfour describes Chegg as declining more than 90% within months; the accompanying slide presents a share-price decline of 90% over nine months. That is a stock-price illustration, not a revenue decline. He points to Stack Overflow as another early casualty after ChatGPT’s launch, without offering a quantified causal analysis.

What do I build, and why will it win?
Product managers are doing more engineering, engineers more product work, and designers more of both. Those changes affect how work gets done. They do not answer the underlying question: What do I build, and why will it win? That has always been product’s central responsibility, even when project management and agile process have obscured it.
Balfour draws on Shaun Clowes, whom he introduces as Confluent’s chief product officer, formerly MuleSoft’s CPO and Atlassian’s first head of growth. Clowes’s formulation is to find an overlooked question that yields an insight other people are not acting on. The last part matters: an insight shared and pursued by every competitor offers little advantage. An insight becomes strategically useful when it opens a course of action others have missed.

Find an opening in a crowded competitive map
A map of Gettysburg supplies Balfour’s analogy for the competitive environment: your product sits among several forces moving at once. His description of strategy becoming ten times harder is rhetorical, but the sources of pressure are concrete.
- Large incumbents: Microsoft, Google, and Meta have scale and are moving quickly.
- Horizontal AI platforms: ChatGPT and Anthropic absorb major use cases that might otherwise support standalone products.
- Technology shifts: Foundational capabilities change on a monthly cadence rather than a yearly one.
- Startup entry: Balfour describes five or six YC startups entering each category with traction in every cohort.
The strategic task is to find an opening among these forces. Infrastructure choices and organizational roles follow that decision; they cannot substitute for it.

From teaching product expertise to encoding it
Balfour brings roughly 25 years in startups to this question. As Reforge’s founder and CEO, he recalls helping launch HubSpot’s CRM about a decade earlier, when entering that crowded category looked implausible. His suggestion that more than half the audience’s companies might now use it is explicitly a guess, not a survey. He considers the present competitive environment substantially more intense.
At the time of the talk, Balfour reports that Reforge had spent roughly ten years serving thousands of product teams and more than 100,000 professionals. Its knowledge base came from more than 400 experts and over 40 expert-led courses. The company then began encoding that expertise into AI agents: Reforge Insights as a product researcher, and Compass as a project manager for lower-value administrative work. Two further agents were planned for that year.
The strategy framework grew out of several months of work with Ravi Mehta, creator of Reforge’s AI Strategy course. Balfour introduces Mehta as a former Tinder CPO with product leadership experience at Facebook, Microsoft, and TripAdvisor. Their starting point is the pair of traps that sit on either side of a useful AI strategy.

Assemble capabilities around what is yours
| Approach | Strategic problem |
|---|---|
| Build custom models and infrastructure first | Treats technical ownership as a prerequisite for strategy |
| Copy basic AI features into the product | Adds capabilities without explaining differentiation |
| Combine available AI with distinctive product assets | Connects capabilities to a specific customer need |
Custom models are not necessary to answer what to build, and a copied chatbot does not answer why the product will win. The useful middle is to treat AI capabilities as Lego pieces: assemble the best available components with your product’s data and functionality.
Competitive advantage comes from what is uniquely yours: your data, your functionality, and your understanding of unmet customer needs. Pretrained models, task execution, audio processing, and image processing create powerful possibilities. But competitors can access those same pieces. Using them is part of building an AI product; their availability alone does not distinguish it.

Evaluate data by its marginal value
Data supplies the context that lets an AI model produce an output specific to your customer. Useful context can come from several sources:
- Real-time data: Information that may not be incorporated into model training.
- User-specific data: Context about the particular person using the product.
- Domain-specific data: Specialized material, such as legal or healthcare information.
- Human judgment: Curation and reinforcement data that capture what people consider useful.
Combining these categories can create something more distinctive than any one category alone.
The test is marginal value, not volume: how much does this data add beyond what competitors have and what the large models already know? A large repository is not automatically an advantage. Its strategic value depends on the additional context it contributes to the customer’s result.

Connect context, output, orchestration, and tool use
Functionality determines how the AI behaves inside the product. Specialized workflows, unique algorithms, business rules, and integrations give the model capabilities it would not have on its own. The advantage comes from connecting these pieces into a system, not merely collecting them.
On the data side, distinctive context informs the AI’s understanding and helps generate a distinctive output. Those outputs can then accumulate into a further repository of useful data, supplying context for subsequent work. That is the proposed feedback loop: context improves output, and output expands the context available later.
On the functionality side, the product controls when it invokes AI and how AI actions fit into the user experience. This is orchestration. The interaction also runs in the other direction: through tool use, AI can call functions exposed by the product. The complete diagram joins both directions of this interaction with the data feedback loop.

Granola’s opening: help me take better notes
Granola entered a market already crowded with AI note-takers, including Fathom, Otter, and Fireflies. From a show of hands, Balfour estimates that roughly 40% of the room had tried or used Granola. This is an informal audience estimate, not market share; his assertion that the response would have been zero a year earlier is a retrospective comparison, not a prior measurement.
He also cites about $50 million in funding without specifying whether he means a round or cumulative funding. For context, Granola’s May 2025 funding announcement reports a $43 million Series B and earlier rounds totaling $24.25 million. The strategic question is how Granola attracted attention despite the crowded field.
Balfour characterizes the existing field—including native capabilities in Zoom and Meet—as trying to replace the whole note-taking job. Granola addressed a different need: help the user take better notes while keeping the user involved.
| Customer need | Product’s role |
|---|---|
| Take my meeting notes for me | Replace the note-taking task |
| Help me take better meeting notes | Enhance the user’s own work |
That distinction changes what the product needs to know and how it should interact with its user.
According to Balfour, Granola started with off-the-shelf capabilities, without unique models or custom training. Deepgram supplied transcription, while Anthropic and OpenAI supplied other AI capabilities. The differentiation lay in the assembly of those services around the customer need.

Turn meeting context into an accumulating repository
Granola’s input combines the user’s own notes with the generated meeting transcript. AI uses both to produce enhanced notes. The user’s contribution is therefore part of the context, rather than work the product simply eliminates. Over time, those enhanced notes form a repository that supports additional capabilities: chatting across meetings, project workspaces, and downstream actions.
The desktop functionality makes that context available at the moment it is useful. In Balfour’s account, the Mac app detects meeting starts and accesses system sound for transcription. Calendar integration contributes metadata such as attendees. Meeting detection should not be read as automatic recording: Granola’s current documentation describes capture as manually initiated. The historical example’s central mechanism remains the connection between product functionality, context capture, and the growing notes repository.

Use the first advantage to build the next
Does that mean Granola will survive? Balfour explicitly declines to predict it. An initial combination of data, AI, and functionality is only a starting point. The next task is to use those assets to assemble another distinctive combination, then repeat.
Granola’s project and team workspaces illustrate this sequence: the initial layer of meeting notes enables shared context and new use cases. Balfour then describes downstream CRM connections, including HubSpot, and reports seeing an experiment with a company wiki that updates itself. The wiki is an experiment in his account, not an established general release. Each extension draws on what the preceding layer made possible.
Balfour attributes the principle to Jamin Ball of Altimeter Capital: “The real moat is just a sequence of smaller moats stacked together.” Each advantage buys time; execution and evolution determine what happens during that interval. Ball’s quoted contrast is six to twelve months for an earlier moat versus two to three weeks today—a strategic characterization of shrinking protection, not a measured universal duration. The practical implication is to build a sequence of advantages, rather than assume the first differentiated feature will remain defensible.

Make the next product decision
The framework turns the next product decision into four questions:
- What customer problem remains unmet?
- Which available AI capabilities could solve it in a novel way?
- What proprietary data would power that solution?
- What functionality can the product give AI so it can deliver the experience?
The customer problem supplies the direction. The other three answers determine how to assemble the product.
Balfour closes by inviting AI engineers to join Reforge, with the team available outside the session and Reforge offered as the follow-up destination. His recruitment pitch includes the claim that engineers could build products with instant distribution to 300,000 people. That invitation places the strategy in a concrete operating context: applying accumulated expertise and an existing audience to the next set of AI products.

[on-hold music] All right.
- 0:16
I need everybody to take a deep breath here because, um, I'm about to stress you out. And, uh, but hopefully at the end, I'll, uh, relieve that stress a little bit with some ideas and solutions for you.
- 0:26
So I need everybody to just think for a second. Reflect on the past forty-five days, and think about all the possible things that have gone on in our industry and all the product launches.
- 0:36
Let me highlight just a few for you. Uh, Notion launched a Granola, Glean, and ChatGPT competitors. Figma launched a Canva, Framer, Illustrator, and Lovable competitor. Atlassian launched a Granola, Glean competitor, plus Claude integrations.
- 0:49
Anthropic launches a Glean competitor with Claude integrations. Google launches Codex, Lovable, and many other competitors. OpenAI bought [audio cuts out], a Cursor competitor, launches Codex, and a lot more. Right? This is just one little microcosm of the entire tech industry.
- 1:05
But if you look around at all the different categories of software right now, the same exact thing is happening. And I haven't even mentioned the horde of startups, well-funded startups, uh, that are getting funded in every single one of these spaces as well.
- 1:21
And among all of this chaos, we have companies that are essentially collapsing in months rather than years. Chegg was one of the first ones to go that declined over ninety percent in the matter of months.
- 1:31
And of course, Stack Overflow was one of the early victims as well when ChatGPT launched. So this gets to the number one question that we all need to be answering, right?
- 1:41
A lot of people at this conference are talking about how product is doing more engineering, engineering is doing more product work, design's doing more product work, all the tactical, all the technical, all of those different infrastructure.
- 1:52
But none of that matters. None of it matters unless you answer this question: What do I build and why will it win? And the interesting thing about this is this was always the job of product.
- 2:04
It just happens to be that over the years, it got marred in all of this, uh, project management, agile process, all of this type of stuff. But this is what always separated great product managers from good product managers and product leaders.
- 2:19
This is Sean Clouse. He's the chief product officer at Confluent. He was formerly chief product officer at MuleSoft. He was the first head of growth at Atlassian as well.
- 2:27
And I thought he encapsulated it well. He said, "You're constantly trying to get ahead. You're trying to find the angle, the question that has not yet been asked that gives you an insight that is not being actioned by other people."
- 2:37
It doesn't just have to be an insight. It has to be an insight that others are not actioning. Because if you find that insight and others aren't actioning it, that is your competitive advantage.
- 2:47
Now, the problem is, is that this question has gotten ten X harder. This is a rough map of, uh, Gettysburg, and I thought it was a good analogy because this was one of the bloodiest battles in the Civil War.
- 2:59
And this kind of represents the map that we are all playing in in the competitive environment right now. We have fast, huge moving incumbents like Microsoft, Google, and Meta.
- 3:09
There are these new huge horizontal platforms like ChatGPT and Anthropic that are eating up major use cases. We have foundational shifts in the technology landscape, not on a yearly basis, on a monthly basis.
- 3:21
And there are hordes and hordes of startups being funded, including five or six in every single capa- category that has traction by YC, every single cohort. This is you sitting in the middle of all of this, right?
- 3:36
And the question is, is how in the world do you find a seam among all of these players to potentially find some traction and win? That's the question we have to answer before any of the other stuff like technology, infrastructure, or even what our roles are in the organization.
- 3:55
I'm Brian. I'm founder and re-- founder and CEO of Reforge. And, uh, if you notice, I have a little bit more [REDACTED:physical_attribute] and [REDACTED:physical_attribute] from this picture because I've been around in tech for about twenty-five years, been doing startups the whole time.
- 4:05
I played in some pretty competitive environments. I helped HubSpot [lip smacks] launch their CRM almost a decade ago. And, uh, at that time, that was a crazy competitive category. People thought we were bonkers.
- 4:17
My guess is if I took a raise of hand, probably over fifty percent of your companies are using that CRM today. Now, that was a competitive environment. But what we're...
- 4:25
I'm experiencing now and what we're all experiencing is probably ten X that. And so, uh, a little history about Reforge is that we've been around for about ten years.
- 4:34
We've helped thousands of product teams, including all the ones you see here, over a hundred thousand professionals. I hope some of you have been part of Reforge in the past.
- 4:41
And the way that we've done it is that we've built a community of over four hundred experts on the front lines to decode all of their best practices. We started by doing that with forty-plus expert-led courses, including our AI courses.
- 4:53
But a couple years ago, we started to take a shift and started to encode all of this knowledge into AI agents. Our first one, Reforge Insights, which acts like your AI product researcher.
- 5:02
Our second one, called Compass, is your AI project manager that takes care of all of those low-level, low-value tasks that involve product management automated for you. We have two more coming later this year.
- 5:14
But back to this question. How do you win in the intense environment in the history of technology? I spent a few months with Ravi Mehta thinking about this exact question.
- 5:24
He created our AI strategy course. He was the former chief product o- product officer at Tinder. He also was a product leader at Facebook, Microsoft, TripAdvisor, and a bunch more.
- 5:33
And the way that we start to answer this question is actually we need to think about the traps. And the two most common traps are, of course, one, how do you like reinventing the AI wheel?
- 5:42
You do not need to build custom models and infrastructure in order to answer this question. And on the opposite side is the other trap, there's the other trap, which is just implementing, copying and pasting basic AI features like chatbots into your product.
- 5:58
The answer actually lies in the middle.
- 6:00
Which is treating AI like a series of Lego blocks, where you assemble differentiated AI features and products by integrating the best available AI capabilities with your product's data and functionality.
- 6:14
Your competitive advantage will come from what is uniquely yours. These three things: your data, your functionality, and your understanding of unmet customer needs, not the AI itself. So let's think about the anatomy of a winning AI product.
- 6:30
What are the major building blocks? What are the major Lego pieces, and how do you stack them together, connect them to create something differentiated? Well, we can start to talk about this, the AI capabilities, because there's a ton of Lego pieces that are emerging every year, whether it's the pre-trained AI models or the abilities to perform tasks,
- 6:50
audio processing, imaging process, all of these new capabilities that feel magical now that we couldn't do before. But the thing about all of these Lego blocks is you just don't have access to them.
- 7:02
Everybody else has access to them as well. So even though AI products and features, of course, use one of these Legos as its core Lego blocks, this is not where differentiation and competitive advantage comes from.
- 7:15
That starts with one of these pieces, your data. Because your data is what provides context to AI, AI model to generate a unique output. The more unique your data is, the more unique output you can generate for customer.
- 7:29
And there's a bunch of different types of data. There's real-time data that the models might not have incorporated into their training set. There's user-specific data. There's domain-specific data like we've seen emerging in la-- in, uh, legal, in healthcare.
- 7:42
There's human judgment da-data around curation as well as reinforcement data. Now, the question about data is: How do you actually combine multiple categories of data together to form some uniqueness?
- 7:54
As well as it's not about the quantity of your data, it's about the marginal value of your data over everybody else, especially the big models. So how much additional value does your data add over what is already trained in the models?
- 8:11
The third piece is your functionality, because this determines how the AI behaves, and it gives your AI product superpowers. There's multiple types of Lego blocks around your functionality: specialized workflows, unique algorithms, business rules, integrations, whatever it is that's baked into your product.
- 8:27
Now, the key about assembling all these pieces is that they work like a system, and you have to connect the system in order to build that competitive differentiation. Let's start with this.
- 8:38
Your data is what provides and informs the AI's understanding. It's what helps you gener-- helps the AI generate a unique output. And that unique output, as a result, is what helps you build an additional repository of unique data so that that continues to f- to flow in a flywheel.
- 8:58
On the other side of the spectrum is your functionality. Your functionality in your product is how your product controls the AI actions, how it interacts with AI when it calls it to create a delightful user experience.
- 9:10
And in addition, AI's addi-- AI's, uh, increasingly able to call tools in the functionality of your product itself, and those two things work together as a system as well.
- 9:22
So let's take all of this theory, and let's put it into practice. Let's talk about a product, Granola. Just by a raise of hands, how many people have either tried or used Granola today?
- 9:32
Okay, pretty decent amount. That's probably like forty percent of the room. A year ago, that would've been zero. And I think this is an interesting case because they entered a space that already had a horde of other AI note-takers, whether that was Fathom, Otter, Fireflies, there was a ton of them.
- 9:51
Um, but somehow, they found a seam, and they've ga- garnered forty percent of your attention in this room and about fifty million in funding. So let's go back to those three fundamental questions in those Lego bricks.
- 10:03
What was uniquely theirs? Their data, their functionality, and their understanding of their unmet customer need. I'm gonna start with the last one. So at the time when they entered the market space, this is, uh, this is just a sample of people who are already in market, including all of the incumbents like Zoom and Meet that have AI-native
- 10:20
note-taking, uh, capabilities. But they were all approaching it from the perspective of the product is going to do something for the user. It's gonna replace the full job. They want somebody else to take my meeting notes.
- 10:33
What they realized is actually there's a whole other set of customer needs that have been unmet, which is, "I don't want you to take all of my notes. I just want you to help me take better notes.
- 10:43
Empower me around this specific task and user." And that's what they built the product around. Now, in order to start, they used off-the-shelf capabilities. No unique models, no custom training, nothing.
- 10:55
They used Deepgram for transcription. They used Anthropic and OpenAI for some of their other functionality. But the uniqueness came in how they assembled the Lego blocks, starting with, on the left-hand side, with Granola's data, right?
- 11:08
Their context includes both the notes that you take as well as the transcription that they generate. They use the AI Lego block to generate a unique output, which is they enhance better notes.
- 11:20
Those notes, over time, form a repository that, uh, starts to enable all sorts of other features that they've layered on, like chatting across meetings, uh, their project workspaces, all their downflow actions.
- 11:32
So they have this nice flywheel of unique context in data that's starting to spin. That was partially enabled by the right-hand side of the Lego blocks, their functionality. They used a Mac app so that they could detect when meetings started to access the system sound for transcription by being right there at the user ha-- uh, the, the
- 11:51
user moment that they needed it to enable the AI to do those things. And they've also plugged into other tools and integrations like the calendar to get metadata about the meetings, such as attendees.
- 12:02
So they assembled these Lego blocks to meet, in that unique way, to meet that unique customer need. Now the question is, is Granola gonna survive? I've got no idea, right?
- 12:14
It's incredibly competitive landscape because the real- the realization is, is that you can't stop here. You can't stop by just assembling your initial set of Lego bricks. You have to sequence over and over again.
- 12:25
You have to take those first three Lego, Lego bricks, leverage them into another unique set that you assemble, and you see Granola doing this. Now that they've enabled this, they've started to create project and team workspaces and start to, uh, enable a new set of unique use cases off of the initial layer that, um, they did.
- 12:44
They've started to integrate downstream actions like, uh, connecting to your CRM and HubSpot. Uh, I just saw them the other day experimenting with a company wiki that auto-updates itself.
- 12:55
So they continue to sequence these things into a unique set of building blocks. The question is, is will they keep up? I don't know. Jamin Ball, a partner at Altimeter Capital, recently wrote a newsletter, and he said, "The real moat is just a sequence of smaller moats stacked together.
- 13:10
Each one buys time. What you do, uh, with that time, how fast you execute, how quickly you evolve, determines whether you stay ahead. If the moat used to be six to 12 months, today it's two to three weeks."
- 13:24
So to recap, to win in AI, besides being stressed out, [chuckles] right, is to answer what are your unmet customer problems. That's always been a part of product, right? The second is what AI capabilities can solve those problems in novel ways?
- 13:38
What proprietary data can power those solutions? And then what superpowers can our product give to AI? How do you assemble those three foundational Lego blocks? All right. Thank you.
