We're Building

Two founders driven by the problems we've seen. We're building tools that actually help and we're always talking to people running startups. Whether it's a calm Tuesday or you're ready to pull your hair out, consider us good friends.

Let us know you!

We'd love to know about the problems you face around finance, data and ops management from day to day.
