About Synthosy

What is Synthosy?

Synthosy is a UK-based marketplace where AI creators sell their work — prompts, agents, fine-tuned models, datasets, tools, workflows, and compute resources — and where businesses and developers buy the AI tools they need.

We believe the best AI tools are built by independent creators, not just large corporations. Synthosy gives those creators a place to reach buyers, earn fairly, and build a business around their expertise.

For Sellers

No listing fee. Ever. We take 6% when you make a sale — that's it. Optional 4% promotion fee puts your listing at the top of its category. Payouts go directly to your bank via Stripe Connect, typically within 2 business days.

For Buyers

Every listing is reviewed before it goes live. You pay the listed price — no extra buyer fees. Secure checkout via Stripe. Cryptographically signed download links. If something isn't as described, our support team will make it right.

Compute Marketplace

The Synthosy Compute Marketplace connects GPU rig owners with developers who need compute. Rent access to real hardware by the hour — SSH or API access, no cloud markups, UK-based hardware available.
