We build software for small businesses — and stay close enough to help them run it.

Our Product

Mainspring

The operating system for small services businesses.

Project management, invoicing, time tracking, accounts payable, client portals, and an AI advisor — in one place. Built for the kind of small teams who don't have time to wire seven SaaS tools together just to send a clean invoice.

Project management for small business owners and startups. Fractional PM, software implementations, process design, and project recovery — hourly on retainer. PMP-certified, MBA, Agile / Scrum / hybrid.
