From scripted bots to a self-healing CX layer that rewrites itself every Friday based on what it heard that week.

We don't ship a CX bot. We ship a learning loop that happens to talk to customers.

Every conversation is a vote. Every vote rewrites the prompt. By Friday, the agent doesn't sound like the one we shipped Monday.

Our NPS climbed 22 points. The product team didn't change. The loop did.
