Why Freeplay?

Freeplay is building the end-to-end platform for software companies to ship great AI products. We give product development teams the power to experiment, test, monitor and optimize their AI features. We provide a single tool to help build better product experiences and move their metrics with confidence. Already we're helping leading software companies from growing startups to large public companies.

Why does the world need Freeplay?

Making simple requests to ChatGPT is easy. But people quickly discover that developing production software with complex prompts and internal data is much more challenging - especially for development teams without prior AI experience. They're motivated to move fast through the learning curve and get back to delivering value to customers.

Our platform streamlines this process - enabling teams to develop & improve production-ready features together quickly and confidently. Then we help our customers optimize their products over time. They like that we help them save time, avoid costly mistakes, deliver better features for their customers, and collaborate to ship faster together.
