Meta buys Stilla.ai for its business messaging agent

Meta bought Stilla.ai, a Swedish AI agent startup, and folded the team into Meta Business Agent — the system that answers your customers on WhatsApp, Messenger, and Instagram. If you automate customer messaging on Meta's channels, your roadmap now belongs to Meta.

What actually happened

Axios reported the acquisition on September 9, and ArcticStartup and MediaPost confirmed it. Terms were not disclosed. Stilla was founded in 2024 and raised about $5 million in pre-seed money — eight months in market, then gone into a trillion-dollar platform. Stilla says its existing platform keeps running for current customers while the team and technology go to Meta.

The target is Meta Business Agent, which launched in June 2026 and, per MediaPost, is now used by more than one million businesses. It answers customer messages, handles the back-and-forth, and increasingly closes the transaction inside the thread. Stilla's contribution is the part that is hard: agents that carry shared context across an organization's tools with real permission boundaries, rather than a chatbot that forgets who it is talking to between messages.

We are reporting the pieces that reputable outlets confirmed. Price, earn-out, and retention terms are not public, so treat any number you see attached to this deal as speculation.

Why a platform-owned messaging agent matters for your business

Two things happen when the platform absorbs the agent layer.

First, the good part: the agent that talks to your customers gets better without you doing anything, because Meta is now paying a team to make it better. If your WhatsApp reply quality is currently "whatever the template says," that floor rises.

Second, the part that costs you: the conversation is the asset, and it lives on Meta's side of the wall. You do not own the transcript, the intent signal, or the escalation logic. When Meta changes what the agent will and will not do — refunds, order changes, pricing questions — your customer experience changes on Meta's schedule, not yours. Meta is also building subscription tiers for businesses using its AI. The free tool you standardized on is a product with a price list waiting to happen.

The move is not to abandon WhatsApp. Your customers are there. The move is to make sure the conversation lands somewhere you control. Pipe every message thread into your own datastore through the Cloud API, keep your own record of what was promised, and keep an escalation path that does not depend on the platform agent behaving. Then Meta shipping a better agent is a gift instead of a dependency.
