Truth Systems builds AI governance and hallucination-detection infrastructure for regulated industries, with a focus on legal firms. Gateway, its core API product, fact-checks LLM-generated text against customer source documents in real time - decomposing a claim into statements, retrieving evidence, and returning SUPPORTS / REFUTES / NOT_ENOUGH_INFO verdicts with character-level evidence spans. Gateway deploys into the customer's own AWS or Azure account via Terraform, with a Python SDK. The company also offers Charter (AI governance for human users) and Alexandria (agent-focused governance), and is backed by Lightspeed Venture Partners.
