Zamp Raises $30M for AI Sales Tax Compliance

Zamp, a pioneer in automating complex sales tax compliance, has successfully closed a $30 million funding round. This significant capital infusion, led by Acrew Capital with substantial participation from Thomson Reuters Ventures and several key accounting firm partners, will fuel the company's expansion and enhance its AI-driven platform. Existing investors Valor Equity Partners, 20Growth, and Friends & Family Capital also contributed, underscoring confidence in Zamp's disruptive approach to a persistent financial headache.

The sales tax compliance arena, a labyrinth of over 12,000 jurisdictions in the U.S. alone, presents a formidable challenge for businesses, particularly in the wake of the 2018 Wayfair Supreme Court decision. This ruling expanded sales tax nexus, forcing companies to navigate a fragmented and ever-changing regulatory environment. Zamp addresses this by offering a comprehensive operating system that manages the entire sales tax lifecycle, from registration and filing to taxability mapping and notice resolution. This end-to-end ownership model is a stark contrast to traditional software solutions that often leave the burden of interpretation and execution with the client.

What sets Zamp apart is its proprietary data layer, meticulously built across thousands of global tax jurisdictions. This deep data foundation, combined with sophisticated AI agents and the oversight of in-house tax and legal experts, allows Zamp to guarantee its filings. The company's commitment to accuracy is backed by a direct penalty guarantee, a powerful differentiator in a field where errors can be costly. This integrated approach ensures that businesses, especially those in e-commerce, SaaS, and digital services, can offload this critical but time-consuming function with confidence.

The market for sales tax compliance is estimated at over $30 billion globally. Zamp's strategy to serve this market includes a strong focus on partnerships with accounting firms. With a significant portion of U.S. accountants nearing retirement, firms are actively seeking scalable solutions to maintain and grow their service offerings. Zamp enables these firms to provide managed sales tax compliance to their clients, either through referral or white-label arrangements, effectively addressing the industry's staffing challenges. Over 120 accounting firms already leverage the Zamp platform.

Rohit Bhadange, CEO and Founder of Zamp, highlighted the company's unique value proposition. "We built our own tax data layer across thousands of jurisdictions globally, instead of relying on third-party data," Bhadange stated. "Second, we own every workflow end-to-end: filing, registration, notices, data normalization, taxability. Third, we pair AI agents with tax and legal professionals to deliver the best outcome for the customer." This focus on owning the outcome, rather than just providing a tool, has led to impressive results, including over 100,000 on-time filings with 99.97% accuracy and more than $300 million in sales tax remitted on behalf of clients.

Zamp's business model centers on an annual fee for comprehensive lifecycle management, a departure from competitors who often charge per transaction or on a percentage basis. This outcome-based pricing, coupled with high client and partner retention rates exceeding 95%, positions Zamp as a resilient and efficient solution, even amidst economic uncertainty. The company's AI-driven leverage ensures scalability without a proportional increase in headcount, contributing to strong operational margins.
