Meta launches enterprise AI platform under ex-MongoDB CEO

Meta launched an enterprise AI platform led by former MongoDB CEO CJ Desai to sell Muse tools, while reports differ on MongoDB's share drop.

Meta CEO Mark Zuckerberg announced Meta Enterprise Platform on 2026-09-28, a new business pillar that will offer Meta's AI stack to companies and developers. Initial products are the Muse agent, Meta Business Agent, Muse API, and Muse Code; TechCrunch adds that the offering builds on Muse, a personal assistant launched earlier in September. Chirantan “CJ” Desai, former MongoDB CEO who previously held senior roles at Cloudflare and ServiceNow, will lead the unit as Chief Enterprise Platform Officer and report to Zuckerberg, and Hacker News, citing Reuters, says he resigned from MongoDB effective immediately. Sources disagree on the market reaction: Hacker News said MongoDB shares fell about 20%, while TechCrunch said they fell more than 17% and that former CEO Dev Ittycheria was named interim chief executive. Meta has not disclosed pricing or the exact business model; The Decoder, citing The Wall Street Journal, says Meta is spending more than $100 billion on AI infrastructure this year and will compete with Claude Code, Codex, Cursor, and low-cost Chinese open-weight models. Meta says security and privacy are built into the products from the start, and the Hacker News item reports no security incident, product flaw, or customer impact.
