Summary
Numeral, a San Francisco-based AI-powered sales tax and indirect tax compliance platform, announced a $100 million Series C funding round led by Insight Partners, with participation from Salesforce Ventures and additional institutional backers. The capital raise brings the company's total funding to $157.5 million since its founding, according to statements from CEO Sam Ross and multiple fintech publications.
The funding round reflects strong momentum at Numeral, which has achieved 327% year-over-year growth in transaction volume on its platform. The company now serves more than 3,500 businesses ranging from high-growth software companies like Supabase and Eight Sleep to e-commerce platforms processing tens of billions in transactions, as well as Big Four accounting firms. This diverse customer base underscores the universal nature of tax compliance challenges across industries and company stages.
Numeral's core value proposition addresses a fundamental operational complexity for businesses operating across multiple jurisdictions. The platform automates the entire tax compliance lifecycle—from determining tax obligations and registering with authorities, to calculating taxes, filing returns, remitting payments, and managing exemption certificates. The company has expanded its coverage to VAT and GST compliance across more than 90 countries while integrating with over 40 billing, financial, and ERP systems, reducing friction for enterprise customers.
The company's expansion trajectory extends beyond its initial ecommerce and software-as-a-service foundation. Numeral is now penetrating manufacturing, distribution, and wholesale sectors where indirect tax complexity is equally acute. This vertical expansion suggests the platform's technology has achieved sufficient maturity and scalability to address industry-specific compliance requirements. The Series C capital will fund product development, geographic expansion, and go-to-market initiatives to accelerate adoption across these new segments.
Founded by Sam Ross and Matt DuVall and backed by Y Combinator (Winter 2023 cohort), Numeral operates in a growing segment of enterprise fintech infrastructure addressing mission-critical but operationally burdensome compliance functions. The Insight Partners-led round validates both the market opportunity in tax automation and Numeral's execution capability in capturing it.
