About Caldera

Caldera enables dynamic, scalable blockchain experiences. Currently, dapps that are deployed to general-purpose blockchain compete with thousands of other applications for space on the network — this can lead to congestion and high fees or even network outages.

That’s where we come in. We’re building software that makes it easy for the most innovative blockchain applications to launch their own ultra-performant blockchains, enabling applications to own their ecosystem, scale to millions of users, and provide a superior user experience.

We’re located in San Francisco, and work in-person from the Financial District.
