Photon gives AI agents iMessage, WhatsApp, and Slack access
Daniel Tian, co-founder of Photon, dropped out of UPenn to build a "Twilio for AI agents" that connects agents to iMessage, WhatsApp, Slack, and Discord through a self-built Mac Studio data center in San Francisco.
Score breakdown
Developers building AI agents can use Photon to deploy those agents directly into messaging platforms users already have, eliminating the app-download friction that typically limits consumer adoption.
- 01Photon is described as 'Twilio for AI agents,' connecting agents to iMessage, WhatsApp, Slack, and Discord.
- 02The company operates a physical Mac Studio data center in San Francisco to relay iMessage traffic, which requires Apple hardware.
- 03A key use case is booking restaurants or tickets via iMessage without downloading a separate app.
Daniel Tian, co-founder of Photon, joined The Log podcast to explain how his company acts as a middleware layer — "Twilio for AI agents" — that plugs AI agents into messaging platforms consumers already use: iMessage, WhatsApp, Slack, and Discord. Rather than forcing users to download a new app, Photon lets developers connect their agents to these channels so end users can simply send a text to interact. A concrete example given is booking a restaurant or reserving tickets entirely over iMessage, with the agent understanding and responding to natural-language requests.
Tian also noted that some providers offer cloud-hosted versions of on-device open-source models, and in those cases Photon supplies the iMessage and messaging-channel access as a service.
Because iMessage requires Apple hardware to relay messages, Photon built and operates its own physical data center stocked with Mac Studios in San Francisco. Tian also noted that some providers offer cloud-hosted versions of on-device open-source models, and in those cases Photon supplies the iMessage and messaging-channel access as a service. Tian left UPenn to work on Photon full time, and the conversation covers broader themes including the impact of AI on software development, fear of job obsolescence, agent-to-agent communication models, AI companion use cases, preventing AI-generated text spam, and the future of payments within chat interfaces.
