Jonathan Widawski
CEO & Co-Founder at Maze
At Maze, we've learned great customer experiences come through intentional testing & iteration. Freeplay is building the tools companies like ours need to nail the details with AI.

Jake Adams
Co-founder at Grain
When we started using LLMs, we immediately realized testing is hard. What Freeplay is doing will give teams the confidence they need to ship faster & improve over time.

Koen Bok
CEO at Framer
We wanted to give our designers the freedom to experiment with prompts, but couldn't find good tools. Freeplay will make it easier to get anyone involved in prompt engineering.
