Built by a Contractor,
For Contractors
SemaQuote wasn't born in a boardroom. It started in the back of a work van after frustrated phone calls and missed jobs.

"He Lost a $45,000 Job Because of a Piece of Paper"
In early 2025, my good friend Rick called me, frustrated beyond belief. He'd just lost a massive bathroom renovation project, $45,000, to a competitor. Not because his work wasn't good. Not because his price was too high. Because his quote arrived three days too late.
Rick is one of the best contractors I know. But like every tradesperson I've ever met, he was drowning in paperwork. Every evening, while his competitors were with their families, he was hunched over his kitchen table, typing up quotes from scribbled notes he'd taken on job sites. Half the time he couldn't read his own handwriting.
The client had loved Rick. They walked through every detail together. He promised to send the quote that evening. But that evening, his daughter had a soccer game. The next day, emergency calls came in. The quote sat half-finished for three days.
"Your work is great, Rick, but Marcus had his quote to me before you even left my driveway."
That conversation haunted me. I started asking around. Other contractors, electricians, landscapers, HVAC techs. Every single one had the same story. Skilled professionals losing work because admin tasks were eating their lives.
The pattern was clear: contractors are amazing at their craft, but the business side, especially quoting, was designed for people sitting at desks. Not for people on job sites with dirty hands and limited time. What if they could just talk through a job and have a professional quote ready instantly?
That question became SemaQuote. I assembled a team, built a prototype, and put it in the hands of real contractors. The results were immediate: quote turnaround dropped from days to minutes. Close rates jumped. And contractors finally got their evenings back.
SemaQuote exists so that no contractor ever loses another job because of a slow quote. Rick uses it now. His close rate is up 40%. And he hasn't missed a soccer game since.
Our Mission
Get contractors back to doing their best work by eliminating the paperwork that keeps them from it.
"Every hour a contractor spends on paperwork is an hour they're not earning, not learning, and not living. We're here to give those hours back."
