## About this market
Startup AI in Warsaw, on this page, runs from research-led machine learning to software houses with AI inside the build, and the published evidence thins in that direction.

Sparkbit publishes model metrics next to the handover: a tower-equipment detector for 5x5 Technologies retrained from F1 0.72 to 0.86, and a posture-analysis core for phy whose algorithms went into the client's FDA application. Its studies also record where work stopped, including a discovery phase whose findings argued against continuing.

QED Software is research-led, founded by Prof. Dominik Ślęzak, and its clearest client evidence sits in named quotes rather than the case studies—DeepSeas' CTO credits models drawn from a contest QED ran with 25% more efficient alert analysis.

Stepwise is a cloud and data engineering team with AI as one part of the product; its one measured model predicted a manufacturer's production-line settings correctly 75% of the time.

The order of questions matters for a startup: decide whether the risk sits in the model or in the product around it, then shortlist the firms whose published work sits on that side.

### How is startup experience verified on this page?
