Perpetual

Perpetual’s history centers on AI agents for operational work, followed by personalized family software. Its early virtual-colleague project, Teammates, connected agents to tools such as Snowflake, Airtable, and Slack for back-office tasks. The team later shut down Teammates and launched SuperDuper, which turned school emails, activity updates, and attachments into family dashboards. Parents could track schedules, registration deadlines, and permission slips, with related messages grouped into a shared view.

Teammates co-founder Benjamin Stein described agents that interpreted runtime errors, corrected malformed API requests, and rescheduled work after a database connection-limit error. These were practical engineering examples of recovery during execution. SuperDuper extended the team’s personalization work through an adaptive application approach: interpreting incoming data to generate a family-specific interface that changed with new activities and circumstances, without requiring parents to specify an application themselves.

SuperDuper was free, but the product is now retired. Its shutdown notice set August 17, 2026 as the app’s end date and announced an agreement to be acquired by Life360, without confirming completion. Customer accounts and data would not transfer; the notice said the team would carry SuperDuper’s ideas into its work at Life360.
