Anrok builds modern sales tax compliance infrastructure for software companies, replacing the manual, error-prone processes that legacy tax tools require. The platform connects to a company's billing and payment systems to monitor tax obligations in real time across US states and international jurisdictions.
Anrok automates the full compliance workflow: detecting where a business has crossed economic nexus thresholds, calculating the right tax on every transaction, registering with tax authorities, and preparing and filing returns. Its AI-native approach is designed to scale global tax compliance so finance teams can focus on growth rather than regulatory busywork.
The company has become a trusted layer for fast-growing technology businesses, serving more than 3,000 global finance leaders. Companies like Anthropic, Cursor and Notion rely on Anrok to automate global tax compliance.
With its Series C, Anrok is accelerating product partnerships, expanding R&D investment in AI, and driving further innovation in global sales tax compliance automation. The round more than doubled the company's valuation to $525 million and brought total funding to over $100 million.
