About Sendence

Sendence provides software infrastructure that radically simplifies the creation, deployment & operation of any business critical real-time service. Our vision is that all applications will eventually move to the cloud, but only if it's industrial-grade.

We believe in open source and strive to build on these technologies and contribute back to the projects we use. Our team is 11 people and growing. We have a lot of green field problems and the chance for each new team member to make a lasting impact on our technology and culture.

Sendence Wallaroo is a high performance distributed streaming data platform that handles the hard plumbing including an API for creation of streaming data flows, in-memory state management, exactly-once semantics, resiliency, and easy application scale out.  Developers use Wallaroo so that they can focus on hard business problems. The platform is written in C/Pony.  Initial applications are written using our C++ API.
