Numeral Raises $100M to Scale AI Sales Tax Compliance

Numeral secures $100 million in Series C funding to expand its AI-driven sales tax compliance platform. The round, led by Insight Partners, joins participation from Salesforce Ventures, Geodesic, Benchmark, Mayfield, FCVC, Y Combinator and Uncork. The funding brings Numeral's total capital raised to $157 million.

Founded in 2023, Numeral aims to streamline the sales tax compliance process through a combination of deterministic tax engine, AI and automation. The company's platform manages nexus monitoring, registrations, tax calculations, filings and remittance, as well as exemption certificates and virtual mailbox services. Businesses can automate 80% of filing and registration work, and reduce manual spreadsheet work and filing errors by up to 95%.

Numeral supports VAT and GST compliance across over 90 countries, and integrates with more than 40 billing and financial systems. Its exemption certificate tools can save businesses up to 400 hours annually, revealing compliance issues that may have remained unidentified.

The company's transaction volume has grown exponentially, with a 327% year-over-year increase. Numeral expects its tax engine to process over 80 million transactions, and its customer base is expanding across software, manufacturing, distribution and wholesale industries. These sectors often face complex tax requirements across multiple jurisdictions.

Numeral is investing the new capital into product development, team expansion and international market growth. The platform is designed to support businesses managing increasingly complex tax obligations, reducing pressure on internal finance teams.
