Summary
$4.5 million in seed funding will help Photon expand tools for developers building AI agents that run through iMessage, WhatsApp and other messaging channels instead of standalone mobile apps.
40,000 developer sign-ups, 10x revenue growth in four months and 5x messaging-volume growth in the last month helped drive the round, according to the startup.
Photon launched its managed platform in April, adding 99.95% uptime plus SOC 2 Type II and HIPAA compliance to an open-source product that still accounts for 98% of usage.
Gradient and A* co-led the round, with Vercel, HongShan and others joining as Photon pitches itself as infrastructure for both human-agent messaging and future agent-to-agent communication.
