Small tools.
Sharper decisions.

Start narrow.
Prove the value.

Small teams regularly lose time turning scattered public information into a decision they can trust. Hammer’s approach is to choose one expensive, recurring question and make the answer easier to review.

That means keeping original evidence close, making uncertainty visible, and testing the product against real customer decisions before making broad claims.

The founding pilot exists to measure the part that matters: whether contractors would actually investigate the projects it surfaces.
