Numeral raises $100M Series C led by Insight Partners for AI tax platform

Sales tax now touches over 13,000 U.S. jurisdictions, and states keep expanding what counts as taxable software.

• Numeral raised a $100 million Series C led by Insight Partners, with Salesforce Ventures, Geodesic, Benchmark, Mayfield, FCVC, Y Combinator and Uncork also participating.
• Founded in 2023 by CEO Sam Ross and CTO Matt DuVall, Numeral automates the full sales tax lifecycle: nexus monitoring, registrations, calculation, filing, remittance and exemption certificates.
• The platform pairs a deterministic tax engine with AI, supports VAT and GST in more than 90 countries, and connects to over 40 billing, finance and ERP systems.
• Numeral's total transaction volume grew 327% year-over-year, and it expects its tax engine to process more than 80 million transactions.
• Customers report cutting time spent on filings and registrations by up to 80%, while 30-40% of migrated exemption certificates fail validation, exposing hidden compliance gaps.
• The raise follows a $35 million Series B in September 2025, bringing Numeral's total funding to roughly $157 million; the company did not disclose its new valuation.
• California recently passed a law extending sales and use tax to prewritten software, including SaaS, starting in 2027 — a preview of the compliance shifts driving demand for automated tax tools.
• As AI makes it economical to automate work once reserved for Big 4 tax teams, compliance infrastructure is becoming a category investors treat as durable operating software, not a niche back-office tool.
