Company profile
researched Aug 2026Entrepreneur Sam Ross and engineer Matt DuVall founded Numeral in early 2023 after Ross experienced multi-state sales-tax filings across ecommerce businesses and DuVall built infrastructure at Stripe, Notion and Box. Numeral combines software/AI with US-based tax experts to monitor nexus, register businesses, calculate rates via integrations/API, file and remit returns, manage notices/mail and exemption certificates, support audits/voluntary disclosure, and expand into VAT/GST. Funding is exactly $57m across a $4m YC/Uncork seed, $18m Benchmark-led A and $35m Mayfield-led B; the September 2025 B valued it at $350m post-money. Customer scale rose from 1,000+ in March 2025 to 2,000+ in September and 3,000+ across 70+ countries by 2026. Named customers include Ridge, Eight Sleep, Graza, Grüns, Manus, Supabase, Brex and Character.ai. Standard public unit pricing is $75 per filing and $150 per registration, with free nexus monitoring/no long contract; advanced real-time calculation is gated to higher packaging. The older numeralhq.com row is the same tax company/domain history and is linked as a duplicate. It is unrelated to the Paris bank-payments company Numeral, acquired by Mambu.
Founding story
Ross's own $50m+ ecommerce operating experience exposed repeated sales-tax pain; he paired with former Stripe/Notion/Box engineer DuVall to automate the workflow end to end.
Business model
Managed compliance software combining agentic automation with tax-expert review.
Usage/unit fees per registration and filing, higher-tier calculation/API and managed services; no long-term contract on standard plan.
Traction
3,000+ customers and 70+ countries by 2026, up from 1,000+ and 3x growth before Series A and 2,000+ at Series B. Current site names Character.ai and YC names Eight Sleep, Supabase and Brex; counts are company-reported.
Latest developments
2026 product adds 70+ country coverage, natural-language reporting, exemption-certificate management and automated tax-mail handling while customer count passed 3,000.
▸Full profile — market position, technology, go-to-market, geography, history, ownership, risks & controversies

Hybrid software-plus-human service with transparent per-filing pricing and an on-time guarantee, initially focused on fast-growing ecommerce/SaaS rather than the entire enterprise indirect-tax spectrum.

Economic-nexus tracking, integrations/transaction ingestion, rules/tax engine and API, agentic registration/filing workflows, remittance, natural-language reporting, notice scanning/response, exemption certificate lifecycle and expert review.
Go-to-market
Free nexus monitoring, content-led acquisition, Shopify/Stripe/accounting integrations, self-serve onboarding plus concierge/expert sales and partner referrals.
Ecommerce, consumer brands and SaaS companies with US multi-state and international indirect-tax obligations.
Founders, CFOs, finance/accounting/tax teams, ecommerce operations, SaaS billing and accounting partners.
Geography
US headquartered; US sales tax across 11,000+ jurisdictions plus VAT/GST compliance in 70+ countries.
History
YC S23/Uncork $4m seed; scaled ecommerce product; Benchmark $18m A March 2025 expanded into SaaS; Mayfield $35m B September at $350m; customer and country coverage continued expanding through 2026.

Risks & controversies
Customers remain legally responsible for tax despite automation; rate/content, filing or integration errors can create penalties. International VAT/GST and enterprise edge cases are complex. Competitors criticize narrower content and feature coverage; published guarantee scope/exclusions matter.
