## Summary

Numeral, an AI-driven sales tax compliance platform, has closed a $100M Series C funding round led by Insight Partners. The company stated it will use the capital to accelerate product development, expand its offerings to sectors like software and manufacturing, and hire across engineering, sales, and marketing. The raise comes as regulatory environments shift, such as California’s 2027 legislation bringing prewritten software into sales tax scope.

Numeral has seen significant growth, with total transaction volume rising 327% year-over-year. The company expects its tax engine to handle over 80 million transactions. Its platform manages the full compliance lifecycle, including nexus monitoring, filings, and VAT/GST compliance in more than 90 countries. It integrates with over 40 billing and ERP systems, combining a deterministic tax engine with AI automation and human specialists for complex cases.

According to Numeral, customers can reduce time on filings by up to 80% and lower manual errors by up to 95%. The company also launched an accounting partner programme, allowing firms to refer clients, resell the platform, or build services on it. Founded in 2023 by Sam Ross and Matt DuVall, Numeral previously raised a $35M Series B in September 2025.
