Key points

  • Photon raised $4.5 million in seed funding.
  • The company develops tools for building agents on messaging apps.
  • Photon reported 10x revenue growth and 40,000 developers in four months.
  • Co-founders believe agents will replace mobile apps.

Seed Funding for Agent Development

AI startup Photon announced it has raised $4.5 million in seed funding. This capital will be used to further develop its products, which enable developers to create agents that function within existing messaging platforms such as iMessage and WhatsApp.

The funding follows a period of growth for Photon, which reported a tenfold increase in revenue over four months and attracted over 40,000 developers to its platform.

The Shift from Apps to Agents

Photon co-founder and CEO Daniel Tian suggests that the era of traditional mobile applications is nearing its end, anticipating a shift towards agent-based interactions. The company even hosted an "app funeral" event in San Francisco, featuring a coffin for app icons and panels with companies like Vercel, Stripe, and OpenAI, to highlight this perspective.

The underlying thesis is that users prefer accessing functionalities through messaging apps they already use, rather than installing new, standalone applications.

Developer Tools for Messaging Platforms

Photon offers a suite of tools designed for developers to build and operate agent experiences across various communication channels. These tools include a unified API, an extensible channel framework, a command-line interface (CLI), and an observability suite.

This platform supports integration with iMessage, WhatsApp, Telegram, SMS, RCS, email, and voice, allowing developers to deploy their applications where users are already active.

Origins and Growth

The concept for Photon originated from co-founders Daniel Tian and Ryan Zhu's experiences building consumer apps. They identified a challenge in app discovery and realized that integrating functionalities into existing messaging apps could provide a solution.

Their initial open-source project, a bot for iMessage, gained traction with thousands of developers, leading them to fully commit to Photon. Tian subsequently left UPenn's M&T program, and Zhu became a visiting student at MIT's Media Lab.
