Jean Deruelle
FounderJean Deruelle is the founder of Soleur, a Company-as-a-Service platform that deploys 60+ AI agents across 8 business departments. He built Soleur to solve the problem he faced as a solo founder: running eight departments with the time and budget for none of them.
Jean is a software engineer with over 15 years of experience building distributed systems and developer tools. Before founding Soleur, he worked across the full stack — from backend infrastructure to developer experience — at companies ranging from early-stage startups to enterprise organizations. His background spans Java, Ruby, Go, and TypeScript ecosystems.
He founded Soleur in early 2026 after recognizing that AI agent orchestration could collapse the operational overhead of running a company. The Company-as-a-Service platform — source-available and running in Claude Code today — has grown to 60+ agents across 8 departments, with 60+ automated workflow skills. Soleur is built using Soleur itself — every agent, workflow, and decision compounds into the product through the Model Context Protocol (MCP).
Jean writes about agentic engineering, solo founding, and the mechanics of the billion-dollar one-person company on the Soleur blog. His thesis: the combination of AI agent orchestration and compounding institutional knowledge will enable the first single-person billion-dollar company.

What does Soleur do?
Soleur deploys AI agents across 8 business departments — engineering, marketing, legal, finance, operations, product, sales, and support — giving a single founder the operational capacity of a full organization. Every agent shares a compounding knowledge base, so your marketing agent knows what your legal agent decided. Your expertise stays in the loop: agents provide drafts, you make the final call.
Is Soleur free to self-host?
Yes. Soleur is source-available under BSL 1.1 — free to self-host for individual and internal business use, fully inspectable on GitHub, and it converts to Apache-2.0 four years after each release. The cloud platform (in development) layers managed infrastructure and a web dashboard on the same core.
What is MCP?
MCP stands for Model Context Protocol — Anthropic's open standard for connecting AI models to external tools, data sources, and services. Soleur is built on Claude Code and MCP, so every agent can reach the same tool ecosystem the broader Claude Code community relies on.
