Announcing Our $3.8M Seed Round to Make Voice AI Agents Reliable 🎙 If 2024 was the year of demos, 2025 is the year of reliable voice agents. We’re excited to share that @HammingAI has raised $3.8M in seed funding led by @MischiefVC, with participation from @ycombinator, @aigrant, @pioneer_fund, @CoughdropCap, @coalitionvc, @orangecollectv, @twentytwovc, @transposevc, @OliveTreeCap and an incredible group of angels. Read more about us here: 1) Blog: hamming.ai/blog/hamming-ai-s… 2) Coverage by Kerry Flynn from Axios: axios.com/pro/media-deals/20… Humans make billions of calls every day. AI voice agents will perform a majority of these calls. Ensuring their reliability is tough — small changes can break responses, and manual testing doesn’t scale. Even when you ship your voice agents to production, teams spend hours manually listening to calls to find bugs and edge cases. At @HammingAI, we automate testing, monitoring, and governance for Voice AI agents, helping teams catch failures, optimize prompts, and flag edge cases in production. Hamming makes your Voice AI agents trustworthy. Thanks to our team, customers, and investors for believing in this mission.
