Describe a strategy in plain English. Tessen builds it and grades it honestly — a real out-of-sample backtest, net of every fee — in about 15 seconds. Most ideas fail. Knowing that before you fund them is the product.
Real screen recording of the live engine — unedited, graded while filming.
The internet's favorite strategy fails our gates. Our own strategy passes them — and still only earns a D, because real edges are thin. Both verdicts are public, permanent, and re-checkable.


Type your strategy in plain English. Tessen turns it into a precise spec and tells you every assumption it made.
A real out-of-sample backtest, net of every fee, behind five hard gates. A letter grade in about 15 seconds.
Run it against live markets with zero risk — no exchange account, no real orders. Free.
Gate-passing agents deploy on your own exchange keys. Kill switch, auto-halts, and alerts when live results drift from the grade.
Build and iterate trading agents conversationally, with an honest grade on every version.
Market intelligence across 10 venues — every signal labeled by whether it survived robustness testing.
Trader memory: post-mortems on every grade, journals on every agent, drift alerts on every deployment.
Copy gate-passing agents black-box on your own keys. Fees on real profit only.
Finance is fragmented across a dozen apps that never talk. Tessen is building the AI layer that connects them — for individuals first, then businesses, institutions, and developers. Each division activates only when its gate is passed: proof, revenue, or licensing. Never hype.
Grading is free and open to everyone. The Studio — iterate, paper-trade, deploy — is invite-only while we grow carefully. Invites go out in batches.
