Playground

Welcome to Playground

Build the future of intelligence with us

AI is still in its infancy. The Playground is a space for all AI developers to deploy their models with the support and tools required to grow. Our program backs builders, researchers, innovators and community pushing the boundaries of what’s possible. We provide funding, tools, research, support, and a connected ecosystem of products to scale into the real world.
Intelligence is shaped by the environment it grows up in.

Why Build Here

Playground is where bold ideas grow responsibly.

Verifiable Guardrails

The potential of AI is exponentially powerful, exciting, and risky without guardrails. The Playground bridges open source and enterprise, where experimentation meets accountability to connect innovation and real-world adoption.

Connected Ecosystem

It’s an intelligent growth environment with

zkML technologies, tools, advanced research, plug-and-play ecosystem

Strategic funding and portfolio support

Marketplace of products and partners that scale with you

Access to powerful resources

You don’t need to be an onchain expert to build with the best. We make potent systems reserved for enterprise accessible to traditional builders to shape what’s next. The future of intelligence needs to be trusted, tested, and built to last.
