    I spent four years at DEWALT managing multi-million-dollar tool-and-fastener lines for Southern California and the Mountain West. Every week I was on job sites — not selling, but listening. The conversations always landed in the same place.

    Getting paid.

    Not winning bids. Not equipment breakdowns. Not material costs. Getting paid. Because in construction, doing the work and getting paid for it are two completely separate events. The gap between them can destroy a business.

    Before DEWALT, I was a journeyman electrician. I pulled wire, bent conduit, and ran panels on commercial sites across Southern California. I know what it feels like to finish a job, send the invoice, and hear nothing but silence.

    One contractor I met had completed a $40,000 plumbing rough-in. Quality work. On time. On budget. The GC went quiet after the final invoice. Stopped returning calls. Then came back with a manufactured dispute about a minor item that had nothing to do with the contract.

    By the time a lawyer looked at it, the contractor had lost the only thing that mattered.

    He had missed a filing deadline.

    Not the deadline to sue. Not the deadline to negotiate. A preliminary notice deadline. A piece of paper he was supposed to mail within 45 days of starting the job. Day one. Before a single invoice was sent. Before there was any sign of a payment problem.

    A piece of paper that says: I am working on this property and I have legal rights.

    He did not know the clock had started. Nobody told him. The law had given him a tool specifically designed to protect him. And the tool expired in silence while he was busy doing exactly what he was hired to do.

    The contractors who never fight to get paid don't have better lawyers. They file a piece of paper before the job even starts.

    I went and looked for the app that solved this. There were services for large firms with compliance staff. There were services for people who already understood lien law. There was nothing that looked a contractor in the eye and said: here is what the law gives you, here is how to use it in two minutes before you leave the job site.

    So I built it.

    Not because I wanted to be in the legal tech business. Because $280 billion disappears from this industry every year. Not to fraud, not to failed work, not to bad contracts. But to missed deadlines and missing information. The law was written for the person doing the work. The person doing the work never got the memo.
