Run trustworthy experiments across your whole product.

No winner is ever declared for you. The evidence is shown, the decision stays yours.

Built for how B2B actually works

Most experimentation tools assume one anonymous visitor at a time. Your customers are accounts, with several people inside them.

The right unit

Randomize by account, workspace or user, and keep everyone inside one customer on the same variant.

Honest reads

Effect sizes with their uncertainty, a minimum worthwhile effect you set, and an inconclusive state that is allowed to stay inconclusive.

Debuggable

Trace why one identity saw one variant, catch a broken split before launch, and see which flags are now debt.

Transparent plans

Metered on the identities an experiment exposes. Evaluating a flag locally is free and always will be.
