About LawnStarter

LawnStarter is the nation's leading on-demand marketplace for lawn care and related services, with over $100M in annual bookings. We're expanding beyond lawn care to become the one-stop shop for all home services—and ProBase is our first major bet in that direction.

About ProBase

ProBase is a free software platform for home service professionals, starting with pool maintenance operators. Our thesis is simple: give pros the tools to run their business for free, help them get more customers, and some will choose to get jobs through our marketplace. We're not a SaaS company charging $50/month—we're building a new on-ramp to the LawnStarter ecosystem.

The Role

This is not a typical product management role. We're looking for someone to take ProBase and run with it—like a founder, but with the backing of LawnStarter's resources, brand, and marketplace.

You'll be an individual contributor with GM-level accountability. Small team, big ownership. You won't be managing a large org; you'll be shipping product, talking to customers, and making the calls that determine whether ProBase succeeds.
