Chassi exists to make software businesses more successful

Increase engagement and reduce churn from within your app.

This isn’t our first rodeo

Brad Jannenga started Chassi to solve a recurring challenge he had experienced in past ventures as a software entrepreneur—inflexible software slowing growth and limiting customer success.

What we believe

A business is only as successful as its customers

Closing a sale is not enough - that’s the beginning. If customers fail to achieve the outcomes they desire, they leave. You need customers that continue to subscribe, expand usage, and champion your brand. That’s success.

Our vision

Forever change the way software businesses are built

Until now, businesses didn’t have a platform to truly understand and address customer behavior. Chassi’s simple APIs work together in an integrated platform to solve those problems.
