Infrastructure for AI agents on iMessage, WhatsApp, Telegram, and more
Photon builds messaging-agent infrastructure so developers can deploy AI agents through channels people already use, including iMessage, WhatsApp Business, Telegram, Slack, and related interfaces. Its open-source Spectrum stack and managed platform provide a unified API, channel providers, CLI, and observability for production agent experiences. Co-founded by Daniel Tian and Ryan Zhu; the company announced a $4.5M seed co-led by Gradient and A* with participation from Vercel and others (TechCrunch, Oct 2026).
