Tessen builds AI-native products with one rule: real data or an honest zero, never a fabricated number.

Tessen started with one product — honest AI trading strategy grading, built on the belief that a strategy should earn its grade against real backtests, not a self-reported win rate. That same discipline now runs a Product Factory that has shipped 7 real products and a real 19-agent AI workforce.

Build AI products that earn trust with real data, not marketing claims — and make that same discipline available to anyone building with Tessen.

Every product in this ecosystem is built and operated by the same small set of AI agents that Tessen itself runs on — not a separate hidden team.
