Chassi exists to make software businesses more successful

Chassi is a technology company that builds back end systems for SaaS businesses. Companies use our SaaS Application Core APIs to manage customers and grow faster.

This isn’t our first rodeo

Our founder, Brad Jannenga, started Chassi to solve the problems he had experienced in his past ventures as a software entrepreneur. Until now, software companies have had to create or stitch together the systems they need to run their business and handle their customers. This approach is still standard practice, and continues to add costs and limit the growth velocity of companies of all sizes. Since 2016, Brad has assembled a highly experienced team to build Chassi, the first platform created to eliminate this massive problem.

Full Story
What we believe

Building a software business shouldn’t be a hackathon

Until now, developers and early stage businesses have been forced to stitch together their core customer systems. That’s a costly process that incurs technical debt, restricts flexibility and ultimately limits growth.

Our vision

Forever change the way software businesses are built

Custom code in your Application Core from stitching together point solutions slows initial development and limits future growth.
