An agency-born tool, not a product meeting.
Couac isn't a VC startup that did a fly-by of the agency world. It's the tool we built for ourselves at G3W, because getting "the button doesn't work" by WhatsApp at 11 PM had run its course.
Origin
G3W is an independent web agency in Lyon, founded by Gianito Riesterer. We ship e-commerce sites, SaaS platforms and redesigns for clients who have neither a product team nor a Linear workspace. The recurring pattern: a client writes that "something is off," we spend 20 minutes reconstructing context, and half the time it's just a browser extension breaking everything.
The trigger
We tried Ybug, Marker.io, BugHerd. Good products, but none connected to an AI agent like Claude or Cursor through the MCP protocol, none was built for those assistants, and none respected our client on the invoice (third-party cookies, aggressive dashboard branding, per-seat pricing that explodes). We wrote the first version of Couac in a weekend. Today, you choose a plan and start directly.
What we stand for
The client is a guest, not a lead.
No third-party cookie on shared boards. No upsell in the widget. No dark pattern.
The AI agent is a teammate.
Couac connects to your AI agent through a native MCP server. Claude or Cursor can read, comment, create tickets. With you, not in your place.
The widget is honest.
Async, defer, zero tracker. We only see what the user voluntarily captures.
The price is published.
Three plans in plain sight, at the bottom of the homepage. You pay before entering the app, with no sales maze.
The team
Small team based in Lyon. Gianito (product, code, design), backed by G3W's tooling and the first teams using Couac who report what breaks. To reach us: [email protected]. We answer, often the same day.
