For AI startup founders · Cursor developers · teams new to agents
AI that proves its work.
SourceA runs your work through a controlled factory — every step gated, every result verified, every job delivered with an auditable receipt you can replay. The model is swappable. The proof is permanent.

The problem
Most AI asks you to trust it.
Agents say "done" without proof. They drift. They can't be audited. You can't ship — or sell, or pass an audit — on what you can't verify. SourceA is the controlled runtime that refuses to ship until it passes — and hands you the receipt.
What SourceA is
A controlled runtime — not a chatbot.
An LLM only proposes a plan. A contract decides what's allowed. Work executes deterministically. A validator verifies it. Every run commits a receipt — output, evidence, and decision — that you can replay and audit.
