Menlo’s Investment in Factory: The System That Builds Software
Coding is AI’s first killer use case, with the world generating more code this year than in all previous years combined. Menlo Ventures has invested in Factory, a company building the system that builds software, as part of the AI coding startup’s latest funding round, announced last month at a $5 billion valuation. The investment follows a public dispute between Factory's CEO, Matan Grinberg, and investor Chris Degnan, who left to join competitor Cognition. Vinod Khosla, an investor in both companies, criticized Factory as a 'struggling second tier competitor.' Menlo's investment is seen as a strong endorsement, with partner Matt Murphy praising the company. The exact amount was not disclosed but described as significant.

Microsoft, Google Accelerate Into AI Coding Market
Microsoft and Google are making concerted pushes into the AI coding market to challenge leaders Anthropic and OpenAI. Google highlighted agentic AI at its developer conference, unveiling Antigravity 2.0 and promoting Gemini 3.5 Flash for coding and agent orchestration; it also raised token quotas after developer complaints. Microsoft plans to announce a new coding model for GitHub Copilot at its Build conference and is shifting Copilot to usage-based pricing. Anthropic leads with Claude Code and upgraded Opus 4.8, which offers a 1 million token default context, and recently closed financing valuing the company at $965 billion while confidentially filing for an IPO. Market research firm Mordor Intelligence projects the AI code tools market will grow from $9.3 billion this year to about $30 billion by 2031.
AI Coding Agents Reshape Software Development in 2026
In 2026 the software development model is shifting from manual coding to agent-driven workflows where AI coding agents analyse repositories, generate production-ready code, run tests, fix bugs, review pull requests and deploy applications. Major technology firms — GitHub, Microsoft, OpenAI, Anthropic and Nvidia — and startups are investing heavily in agentic development. GitHub’s Copilot initiatives are evolving toward autonomous agents that can be assigned issues and submit pull requests, while Microsoft presented Build 2026 plans positioning Windows as a platform for AI agents with new frameworks and secure execution environments. The shift promises productivity gains but raises infrastructure, security, licensing, governance and code-quality challenges that organisations must address.
Factory Raises $150M at $1.5B Valuation
Factory, a startup building AI agents for enterprise engineering teams focused on AI-assisted coding, raised $150 million at a $1.5 billion valuation in a funding round announced April 16, 2026. The round was led by Khosla Ventures with participation from Sequoia Capital, Insight Partners and Blackstone; Keith Rabois (Khosla Ventures) joined Factory’s board. Founder Matan Grinberg says Factory differentiates by switching between foundation models (e.g., Anthropic’s Claude and China’s DeepSeek). Factory, founded in 2023 after Grinberg left his PhD program following outreach to Sequoia partner Shaun Maguire, counts customers including Morgan Stanley, Ernst & Young and Palo Alto Networks. The raise positions Factory among several competitors in AI coding such as Anthropic, Cursor and Cognition.
