Zamp Secures Funding Led by Acrew Capital to Build End-to-End Sales Tax Compliance Infrastructure

Sales tax has a way of humbling even the sharpest finance teams, not because it’s complex on paper, but because it compounds quietly across jurisdictions until precision turns into pressure. Zamp steps into that tension out of New York, not as another tool in the stack, but as a system built to carry the weight. Zamp OS calls itself the operating system of sales tax, and that label only works if you’re ready to own everything that comes with it.

Now the market just leaned in. Zamp raised fresh capital led by Acrew Capital, with Thomson Reuters Ventures participating, bringing total funding to $30M. That’s not just a number, that’s a signal. When firms that live and breathe financial infrastructure start writing checks, they’re not chasing noise. They’re betting on inevitability.

Rohit Bhadange, Co-Founder & CEO, has been building this like someone who’s seen the chaos up close and decided spreadsheets weren’t going to win, while Edward Lando, Chairman & Co-Founder, brings the kind of pattern recognition that doesn’t flinch when markets get crowded, different lanes, same highway, moving fast.

And Zamp isn’t playing small ball, they’re covering more than 12,000 jurisdictions, all 50 states, and more than 100 countries, with over 120 accounting firms already in the system, not just using it but leaning on it to scale without hiring armies they can’t find anyway.

The pressure underneath all this is structural, 75% of U.S. accountants are approaching retirement, the pipeline behind them isn’t keeping pace, and the workload isn’t slowing down, fewer people, more complexity, and 0 tolerance for mistakes, the kind of environment where brittle systems don’t survive.

Zamp’s angle is simple, but not easy, own the entire workflow, registration, nexus, calculation, filing, remittance, notices, then back it up with a penalty guarantee, that last part is where things get interesting, anyone can sell software, not everyone is willing to stand behind the outcome when things go sideways.

That’s the difference between a feature and infrastructure, and infrastructure is where real leverage lives, Acrew Capital and Thomson Reuters Ventures didn’t just fund a company, they leaned into a shift where compliance stops being a burden and starts becoming something you can actually scale without losing sleep or sanity.
