Stilla said on September 9, 2026 that it is joining Meta. The Stockholm company, which launched its multiplayer AI agent product eight months ago, wrote that the team will bring that software into Meta’s AI products for business. Cofounders Siavash Ghorbani and Kaj Drobin signed the note with the rest of the staff.

The company post is the only primary on the deal. It does not name a price, a close date, or which Meta product the code will sit in. It does say Stilla will keep serving current customers and that the product remains the agent platform those teams already use.

Stilla described the work those customers already give the agent: building products end to end for supply chains that serve millions of people, scaling onboarding at a fast-growing company, and monitoring a large investment portfolio. The pitch is that an agent inside a business should do the work, earn trust, and change how the organization runs, and that Meta’s scale is the way to take that further.

Meta has not published its own announcement. Stilla did not list investors, headcount, or a shutdown timeline for the independent product.

Decoded Take

Talent and product tuck-ins are how large labs absorb agent startups without a splashy price. The part that matters for Stilla’s users is whether “continuing service” means the Stockholm product stays on its own rails, or whether accounts get quietly folded into a Meta business agent and a new terms-of-service page. The post is careful and short, which usually means the commercial paper is still being written. Watch for a Meta product page that names Stilla, a migration notice to existing workspaces, and whether European customers get a data-residency answer before the independent login disappears.
