Notius Labs

Notius Labs is an independent consultancy helping healthcare technology companies build and deploy AI applications. Its consulting services focus on incorporating domain expertise into LLM applications, designing practical evaluations, and monitoring performance after deployment. The work translates clinical and institutional knowledge into prompts, evaluation methods, and system architecture, helping teams move from AI pilots to products used in operational workflows.

Founded by Dr Christopher Lovejoy, the consultancy draws on his background as a medical doctor and AI product builder, including previous roles as Head of Clinical AI at Anterior and founding AI lead at Cera. His published engineering guidance describes how domain experts can define failure categories, review model outputs, and assess agreement between reviewers. It also advocates giving a principal domain expert responsibility for defining and judging AI quality.

Lovejoy’s consulting practice targets healthcare and life-science startups at Series A and beyond, alongside providers, payers, pharmaceutical businesses, and medical-technology companies. Its scope extends beyond application development to helping teams hire and train staff and adapt operational processes for LLM-powered products.
