Pylon

Agentic B2B customer support platform.

Pylon turned eval discipline into a merge rule — every AI prompt checked into the codebase needs a Braintrust playground ID or the CI test fails, and the curated dataset behind that playground travels with the prompt. Eval sets are distilled from the rare failure modes in production traffic, scorers are spun up with Loop, and a Claude Code skill reconstructs incidents through the Braintrust MCP.
