## About

Based in the United States, Zamp, Inc., operates as a B2B sales-tax compliance platform developer. The company provides automated tax calculation, end-to-end sales-tax filings, and managed compliance services for businesses and accounting firms.

Based in New York, United States and founded in 2022, Zamp, Inc. provides software and managed services for sales-tax compliance in the fintech and tax-technology space. The company was initially launched as a fully managed service and later evolved into a vertically integrated sales-tax operating system combining AI agents with in-house tax professionals. Zamp supports compliance across thousands of tax jurisdictions globally. In April 2026, the company announced total funding of USD 30 million to scale its platform and expand accounting-firm partnerships. As of April 2026, the company is led by its CEO, Rohit Bhadange, who also founded the company.

The company works with businesses and accounting firms to deliver fully managed sales-tax compliance solutions. Zamp’s platform, branded as the Operating System of Sales Tax (Zamp OS), combines AI-driven automation with tax and legal expertise to manage registrations, taxability mapping, filings, notices, and data normalization. Its offerings include rooftop-level tax calculations, nexus monitoring, API integrations, and white-label services for accounting firms. Zamp’s solutions are built by teams of software engineers, AI specialists, and tax professionals and serve e-commerce, SaaS, fintech, and accounting firms operating across multiple jurisdictions.

The company’s revenue is generated by providing sales-tax software and managed compliance services to businesses and accounting firms. Zamp engages in B2B transactions through subscription-based access to its platform, bundled with tax filings, registrations, and notice management. Additional revenue is derived from advanced integrations, API usage, and white-label partnerships that allow accounting firms to offer fully managed sales-tax services to their clients.

The company plans to use the April 2026 to scale its accounting-firm partnerships, develop new AI-powered product capabilities, and expand internationally.
