Menlo Ventures Leads Investment in AI Coding Agent Startup Factory
Menlo Ventures has announced an investment in Factory AI, an AI coding agent company, with the deal led by partner Matt Murphy. Factory builds an automation platform covering the full software lifecycle, including planning, code review, testing, security, and documentation. Its customers include Nvidia and Blackstone, and it serves hundreds of thousands of developers. Founder Matan Grinberg (matanSF) and Menlo's Ann Bordetsky both posted to confirm the investment.
Confirmed
- Menlo Ventures led the investment in Factory AI, spearheaded by Matt Murphy (m1, m2)
- Factory's product covers the full software lifecycle—planning, review, testing, security, documentation—with customers including Nvidia and Blackstone, serving hundreds of thousands of developers (m1)
- Matt Murphy previously led Anthropic's Series D in January 2024 (m2, m3, m4)
- Sequoia's Shaun Maguire noted that Menlo led Anthropic's round at a valuation of roughly $4 billion, at a time when most people believed OpenAI would be the only winner (m5)
Why it matters
- Claims cited in the post say the AI coding market grew from $550 million to $30 billion in two years (m1), showing how rapidly the coding agent space where Factory operates is expanding
- Murphy's track record (backing Anthropic early) is repeatedly cited by both the founder and investors as validation; Sequoia's Shaun Maguire directly compares this investment to Menlo's early bet on Anthropic, signaling top-tier firms' continued conviction in the AI agent space
