Built by an operator who's done this at scale.

I spent eight years at HubSpot building signal-based prospecting systems for one of the largest sales teams in the world. I helped build out the Clay program there — the same toolset and approach that the best B2B sales orgs in the world now run on.

The thing nobody talks about: the hardest part of that work wasn't the tooling. It was teaching reps and operators how to think in signals — how to spot the moments where a buyer goes from "not in market" to "actively looking" — and how to show up at exactly that moment with the right message.

Commercial service businesses are sitting on the biggest untapped opportunity for this approach. Almost nobody in commercial cleaning, commercial trades, or B2B accounting is doing real signal-based prospecting yet. The handful that do are eating the rest of the market.

Mainstreet Pipeline exists to give serious commercial service business owners the same advantage — without making them learn new software, hire a new team, or trust another agency.

If you run a commercial service business and you're tired of being told marketing is the answer, I'd like to talk.
