# Numeral Raises $100M Series C to Scale AI Tax Compliance as SaaS Regulations Expand **Author:** Zero G Talent **Published:** 2026-10-31 **Category:** business-finance **Tags:** yc-hiring [Read on Zero G Talent](https://zerogtalent.com/blog/numeral-raises-100m-series-c-to-scale-ai-tax-compliance-as-saas-regulations-expand) --- [Numeral](https://zerogtalent.com/frontier-companies/numeral) has raised $100 million in Series C funding to expand its automated sales tax platform, bringing its total funding to $157 million. Insight Partners led the round, with participation from Salesforce Ventures, Geodesic Capital, Benchmark, Mayfield, FCVC, Y Combinator, and Uncork Capital. The San Francisco-based company manages sales tax, VAT, and GST compliance across more than 90 countries. As states and international bodies update their indirect tax rules—such as California passing legislation extending sales and use tax to software-as-a-service starting in 2027—finance teams face steep operational challenges. Numeral processes calculations, filings, remittance, exemption certificates, and nexus monitoring, with total transaction volume growing 327% year over year. The platform expects to process more than 80 million transactions annually. ## Combining Deterministic Calculations with AI Agents Indirect tax compliance requires strict mathematical accuracy alongside administrative coordination across hundreds of local jurisdictions. Numeral integrates directly into checkouts, billing software, and more than 40 ERP systems to embed tax logic. The company pairs a deterministic calculation engine with AI automation to handle registrations, returns, and exemption certificate checks, while keeping human tax specialists in the loop for edge cases. In an interview with [Yahoo Finance](https://finance.yahoo.com/video/pays-ai-makes-mistake-taxes-201638344.html), co-founder and chief executive Sam Ross noted that the company backs its calculations with financial guarantees: "Numeral offers a guarantee, a very large guarantee for our clients. So if there is a mistake or there's a late filing, we cover those penalties." Ross confirmed that the platform serves nearly 4,000 customers, including e-commerce brands like Eight Sleep and Graza, and infrastructure and fintech providers like Supabase and Brex. According to reporting from [Tech Funding News](https://techfundingnews.com/numeral-raises-100m-to-turn-ai-into-a-full-time-sales-tax-accountant/), businesses migrating to Numeral find that 30% to 40% of their existing exemption certificates fail validation on the first pass, highlighting widespread compliance gaps. Numeral reports that customers cut manual spreadsheet work and filing errors by up to 95% and reduce filing time by up to 80%. Technical teams are expanding the tax infrastructure by adding roles like [Software Engineer (AI)](https://zerogtalent.com/frontier-jobs/numeral/software-engineer-ai-89677) and [Software Engineer (Platform)](https://zerogtalent.com/frontier-jobs/numeral/software-engineer-platform-114411). ## Leadership with Platform and Scaling Experience Numeral was founded by [Sam Ross](https://zerogtalent.com/people/sam-ross) and [Matt DuVall](https://zerogtalent.com/people/matt-duvall), alongside founders [Jake Moffatt](https://zerogtalent.com/people/jake-moffatt) and [Kevin Liu](https://zerogtalent.com/people/kevin-liu). DuVall serves as chief technology officer. He spent 2014 to 2019 at Stripe, where he launched Stripe Checkout and Stripe Radar, before leading engineering teams focused on performance and product at Notion between 2020 and 2022. Ross, who previously led growth and product initiatives at Airbnb and Teespring, ran an e-commerce studio that generated more than $50 million in revenue before starting Numeral. The company has built its operations around direct relationships with government tax authorities. As Vice President of Finance Hudson Bova told [CFO Dive](https://www.cfodive.com/news/numeral-first-nailed-down-metrics-raised-100m/833169/), Numeral formalised its revenue reporting around recurring product usage, such as charging $75 per filed tax return and a one-time $150 registration fee. Bova noted that Numeral established integrations with state agencies following the 2018 *South Dakota v. Wayfair* Supreme Court ruling, creating durable channels that states are reluctant to duplicate across dozens of vendors. ## Growth Across Partner Ecosystems and International Markets Numeral is expanding beyond self-serve e-commerce into manufacturing, distribution, wholesale, and enterprise software. In October 2026, the company introduced the Numeral Partner Program, covered by [Accounting Today](https://www.accountingtoday.com/news/numeral-announces-partner-program-with-revenue-sharing-support) and [CPA Practice Advisor](https://www.cpapracticeadvisor.com/2026/10/26/numeral-introduces-program-to-help-support-partners-growth/192550/). The program lets accounting and advisory firms, systems integrators, and value-added resellers resell, white-label, or embed Numeral into client practices with multiyear recurring revenue sharing and Platinum support tiers. To manage this distribution expansion, the company is hiring a [Senior Strategic Partner Manager, ERP Ecosystem](https://zerogtalent.com/frontier-jobs/numeral/senior-strategic-partner-manager-erp-ecosystem-90211) and building out global operational coverage with roles such as [Business Operations Manager (International)](https://zerogtalent.com/frontier-jobs/numeral/business-operations-manager-international-83974). ## Open Roles at Numeral Numeral has an 85-person team headquartered in San Francisco, with an office in New York and distributed remote personnel.
