Zamp, founded in 2022 and headquartered in the United States, is a vertically integrated sales tax compliance platform that combines AI agents with licensed tax professionals to manage the full compliance lifecycle, including nexus monitoring, registration, filing, audit support, and notice management. The company is led by co-founder and CEO Rohit Bhadange, a former investment banker and private equity and venture investor, alongside COO Cleet Wirtz and co-founder Edward Lando.
Zamp reached $1M ARR within six months of its 2023 launch, grew to $5M ARR by early 2025, and has since reached $10M in revenue as of 2026, serving approximately 1,500 customers. The company has raised $30M across three rounds: a $4M pre-seed in 2022, a $9.5M seed led by Valor Equity Partners in mid-2024, and a $16.5M Series A led by Accru Capital in 2025 with participation from Thomson Reuters Ventures. The latest valuation stands at $30M and the team has grown to 51 full-time employees.
The single most distinctive strategic fact is that 50 to 65 percent of Zamp's revenue flows through an accounting firm partner channel, where firms either white-label the product or refer clients, mirroring the channel playbooks of Gusto and Bill.com. Zamp's largest single customer, an accounting partner, pays $500,000 per year for compliance across more than 1,000 state-level filings, and the company has processed $400 million in total tax remittances since inception at a stated 99.97 percent accuracy rate.
