Round
Lead investor

Zamp has secured $30 million in a Series A funding round led by Acrew Capital, underscoring its position in the sales tax compliance sector. The financing attracted participation from Thomson Reuters Ventures and several of Zamp's own accounting firm partners, as well as previous supporters such as 20Growth, Friends & Family Capital, and Good Friends Venture Capital. The funds aim to scale Zamp's operations that provide a comprehensive solution to the increasingly complex landscape of sales tax compliance.

Zamp presents itself as a turn-key operating system for sales tax, integrating AI technologies with the expertise of tax and legal professionals. The platform manages the entire lifecycle of sales tax compliance including filing, registration, notices, and taxability mapping. Importantly, Zamp differentiates itself by guaranteeing outcomes; if an error occurs, the company itself absorbs any penalties. To date, Zamp has completed more than 100,000 precise and timely filings across over 12,000 jurisdictions. The platform boasts a remarkable 99.97% accuracy rate and has facilitated the remission of over $300 million in sales taxes on behalf of clients. More than 120 accounting firms utilize Zamp's platform, confirming its growing acceptance in the market.

The strategic rationale for this funding round stems from the widening regulatory obligations following the U.S. Supreme Court’s 2018 Wayfair decision. Businesses are now required to manage sales tax duties across a vast array of U.S. jurisdictions, a task compounded by the anticipated shortage of tax professionals due to waves of retirements. Zamp aims to alleviate these burdens for finance teams by providing an automated and reliable compliance solution, thus filling a critical gap in the market.

Zamp’s advancement highlights shifts within the sales tax compliance sector. The rise of AI-driven solutions, capable of efficiently processing the complex statutory requirements across multiple jurisdictions, places additional pressure on legacy vendors. By offering beyond-software solutions and guaranteeing compliance outcomes, Zamp may prompt competitors to innovate or collaborate in order to remain relevant.

Looking ahead, the new capital injection will likely support further technological developments and broaden Zamp's market reach. As the regulatory environment continues to evolve and the supply of tax professionals lags, the company is positioned for sustained growth. The implications for global compliance are significant, with Zamp poised to play a leading role in shaping the future of automated tax compliance solutions.
