Numeral applies artificial intelligence to track changing tax regulations across more than 11,000 jurisdictions, prepare filings, manage tax-related mail, and remit payments on behalf of clients, effectively replacing a human tax accountant. The product is built to address the post-2018 mandate that online sellers collect tax wherever customers reside, a pain first experienced by co-founder and CEO Sam Ross while running DTC brands. Numeral now services over 2,000 software and e-commerce businesses, including EightSleep and Graza Olive Oil, and claims 3.5× revenue growth in the past year. Its ability to handle international filings—from Tanzania to Kenya—sets it apart from rivals such as Anrok and Zamp. The company was created in 2023 after Ross went through Y Combinator and is currently valued at $350 million. By leveraging well-defined tax rules, the startup argues its AI faces low hallucination risk while navigating obscure regulations like New York’s “cut bagel” tax rule.
