The Agent2Agent (A2A) Protocol is an open standard that enables autonomous AI agents, regardless of vendor or framework, to securely discover capabilities and collaborate on complex, multi-step tasks.

A2A is the Agent2Agent Protocol: a standardized communication layer for multi-agent AI systems, contributed by Google and housed under the Linux Foundation. It solves interoperability issues by using an 'Agent Card' (a public JSON metadata file) for capability discovery and relies on JSON-RPC 2.0 over HTTPS for secure, structured messaging. This framework allows a 'client agent' to delegate tasks to specialized 'remote agents,' supporting interaction modes like synchronous request/response, real-time streaming (SSE), and asynchronous push notifications for long-running workflows. For example, a single travel agent can use A2A to coordinate with separate, vendor-specific agents for flight booking, hotel reservations, and local activity scheduling, automating a complex enterprise process.

### [Building a full-stack AI business co-founder](https://amsterdam.aitinkerers.org/talks/rsvp_iQHibU-m7a8)

Starnus makes the vision of a 1-person billion-dollar company achievable. Founders can rapidly build products with AI but what about running their business? Starnus simplifies marketing, sales, funding, and daily operations by integrating third-party AI agents/tools and orchestrating them within its infrastructure. Users can get complex tasks done through simple prompts. Our marketplace and pay-as-you-go model ensure simplicity, affordability, and scalability. In the talk, I want to focus on 1 or 2 of our workflows, mainly investors finder and lead generator, and how we've integrated with 3rd party AI agents/tools, and also by utilizing Gemini, we've achieved a result 10X better than any generic tool like ChatGPT.
