We’ve lived it.
The failures, the endless space of choices, the signal you missed and the context you didn’t have. We built tessel to turn high-stakes decisions from educated guesses into a science.
What we believe
- An eval means nothing without its decision.
So we build evals and benchmarks from the decision, not the other way round.
- Not every question is worth asking.
Only the ones that could change the decision, asked so the answer holds up.
- Autonomy has to be earned, not assumed.
Decisions run on their own only where the evidence says they’re safe to.
