The round was led by Mayfield, with participation from Benchmark, Uncork Capital, Y Combinator, and Mantis. The announcement follows a year of rapid growth for Numeral, which has processed over $5 billion in transaction volume, filed 150,000 sales tax returns, and achieved 3.5x year-over-year revenue growth.

The Series B builds on earlier financing rounds, including a $4 million seed from Y Combinator and Uncork Capital and an $18 million Series A led by Benchmark Capital in March of this year. Together, these bring total funding to $57 million. Funding will fuel continued product innovation, global expansion, and AI-driven automation capabilities.

Numeral, founded in 2023, simplifies the full lifecycle of sales tax compliance for e-commerce and SaaS companies: from nexus tracking and registrations to filing, remittance, exemption certificate management, and virtual mailbox services.
