Hamming AI
San Francisco company from Y Combinator's Summer 2024 batch that tests AI voice and chat agents with simulated callers, red-teams them, and monitors production calls.
Teams building AI voice agents for healthcare, banking, and customer service that need automated testing before launch and monitoring after.
Teams that only build text chatbots, or buyers who want published self-serve prices.
Verdict
Hamming AI is a San Francisco company that tests and monitors AI voice agents by placing simulated calls and reviewing real ones. It suits teams shipping voice agents in healthcare, banking, and customer service, where a wrong answer can hurt customers. Its focus on voice gives it depth that general AI evaluation tools lack.
