Photon, a startup building agent developer tools, announced $4.5 million in seed funding on October 1, co-led by Gradient and A*, with Vercel, HongShan and others participating.
Photon lets developers build agents that run inside messaging apps people already use — iMessage, WhatsApp, Telegram — rather than asking users to install new apps. Its open-source version still accounts for 98% of usage, and the hosted version is SOC 2 Type II and HIPAA compliant.
The company says more than 40,000 developers have signed up and revenue grew 10x in four months, but it disclosed no absolute revenue figures, and the funding status rests on TechCrunch's single report.
