Numeral has raised a $100M Series C, led by Insight Partners with participation from Salesforce Ventures, Benchmark, Mayfield, Uncork, Y Combinator, FCVC, and Geodesic.

This brings our total funding to $157M.

@numeral solves U.S. sales tax, VAT, and GST compliance for 3,500+ global businesses, trusted by companies like Supabase, Eight Sleep, and Graza.

We’re building the future of tax -- where AI agents, human expertise, and global compliance come together in one system.

Since starting the business in 2023, we’ve grown quickly across our core e-commerce and software segments, while expanding into new industries including manufacturing, distribution, and wholesale.

There is a lot of work in front of us. Sales tax is more dynamic than ever, with states like California implementing new taxes on software and more states using AI for enforcement.

We are hiring across the org from engineering to product, sales, and marketing. And we’ve just opened our new office in NYC. If you are looking for what’s next, I’d love for you to take a peek at our careers page.

Excited for the year ahead. And humbled to be working with investors like @insightpartners, @rebeccaliudoyle, @SalesforceVC, @katiessschwartz, @ZKokosa, @MayfieldFund, @SPangulur, @benchmark, @chetanp, @ycombinator, @gustaf, @uncorkcap, @susanwliu, @GeodesicCap, @arvindayyala, @FundersClub, @mittal, @mantisVC, @AlexPallNY, @ShaanVP, @lennysan, @moizali, @ringmybeller, @khency6, @asturnerr, @maariabajwa and so many others.

Sales tax is coming. And we are giving away California registrations for free.

Starting January 1, 2027, California will tax most software. For many founders and teams, this means collecting, filing, and remitting for the first time.

For a software business, sales tax has typically been something to worry about at, let's say, the Series A, or when your business is getting close to eight figures in ARR.

But SB 122 changes this logic. The risk is really under-collection, or lack of collection, creating a future liability for the company.

@Numeral is doing two things through the end of the year:

- we will do a free tax analysis
- we will handle your California registration for free

The offer is open to any software companies that aren't yet Numeral customers.

DM @NateMatherson. He will get you squared away.
