AI agents for your business.
They answer, file and follow up.

We build AI agents that answer your customers, handle paperwork and run processes on their own, then teach your team to run them. We are Yonatan Gross and the AI agents that work with him. We built a WhatsApp AI platform and OrchestKit, an open-source Claude Code agent framework (90 skills, 36 agents, 163 hooks).

Yes. Full developer & API docs cover authentication, endpoints, and examples. POST /api/chat with JSON body {"messages":[{"role":"user","content":"..."}]} (up to 20 messages, each up to 2000 chars). Public, no auth, rate-limited to 10 requests per IP per minute, backed by the claude-haiku-4-5 model, streaming a text/plain response. See also /llms.txt and the agent-skills index.

Engagements are scoped per project, so there is no fixed price list - quotes depend on what you are building. The fastest path to a quote is to book a free 15-minute intro call at cal.com/yonyon/15min, describe the work, and get a scoped proposal. You can also email [email protected]. See /pricing.md.

You work directly with the person who designs, builds, and operates the system - no account managers, no hand-offs, no junior bench. We ship production AI end-to-end (RAG, multi-agent, MCP servers, and the infrastructure they run on) as a single accountable point of contact, and we have done so in production (a WhatsApp AI platform) and in the open (OrchestKit). For teams that want senior, hands-on ownership rather than a staffing layer, that directness is the difference.
