# PerfectBit, Inc.

> Verifier-grounded training data for frontier AI models. PerfectBit generates and verifies data against external ground-truth sources — formal proof systems, physics and scientific simulators, executable tests, and oracle databases — across text, code, image, audio, and video. Stated goal: let AI labs "train on reality, not noise."

PerfectBit is a Y Combinator-backed, San Francisco-based B2B data provider. It positions verifier-grounded (formal-system-verified) data as more reliable than human annotation alone for frontier-model training. The company engages AI labs through pilot conversations and does NOT currently publish a public API, developer platform, SDK, or documentation surface. Engagement is sales-led via a contact form.
