2023Lessons From Building Claude
In 2023, as Anthropic’s co-founder and product engineering lead, Mann gave a talk at The AI Conference titled “Lessons Learned while Building Anthropic’s LLM Product, Claude,” covering his top lessons from building Claude, including techniques for aligning an AI system with human values and bootstrapping scalable oversight of model outputs. He has said his goal is to develop AI systems that are helpful, harmless, and honest.[1][1][1]
January 13, 2026Expansion of the Labs Team
On January 13, 2026, Anthropic announced the expansion of Labs, a team that incubates experimental products at the frontier of Claude’s capabilities; former chief product officer and Instagram co-founder Mike Krieger moved to Labs to build alongside Mann. This approach of experimenting at the frontier and then scaling what works had already produced Claude Code, the Model Context Protocol, Skills, Claude in Chrome, and Cowork.[4][4][4][4][4][5]
Inviting Early Testers
Mann once invited Sigil Wen, who later founded Conway ResearchConway ResearchConway Research is an artificial intelligence lab founded by Sigil Wen that works on efficient models, inference engines, and personal AI that runs on devices users already own; its first product is Underdog, a locally run personal assistant. In October 2026, Andreessen Horowitz announced that it was leading the company’s first funding round.Open the full entry, to become one of the earliest testers of what became Claude.[6]
