How Anrok is Scaling the Global Tax Compliance Engine

Anrok, developer of global tax compliance infrastructure, led by Kannan Goundan and Michelle Valentine, has secured $55 million in Series C funding led by Spark Capital, with participation from Sapphire Ventures and existing investors Khosla Ventures, Sequoia Capital, and Index Ventures, bringing the total funding to over $100 million.

Modern companies are scaling faster than ever, launching new products, reaching global markets, and reshaping industries. Behind that momentum, Anrok powers its growth by simplifying one of the toughest challenges: global tax compliance.

Over 3,000 finance leaders, including teams at Anthropic, Cursor, and Notion, rely on Anrok to stay compliant across 100+ countries. More than 40% of the Forbes AI 50 trust its platform to manage global tax complexity so their teams can focus on innovation, not red tape.

The result: 90% less time spent on sales tax each month, engineers freed from financial workflows, and finance leaders with peace of mind. That’s the impact Anrok is built for.

From analyzing over $1.4B in monthly revenue, Anrok found that as companies scale, tax complexity explodes, filing requirements grow 47x, jumping from just 2 filings under $1M in revenue to more than 90 at $50M+. Meanwhile, taxable revenue more than doubles from 20% to over 50% as businesses expand globally.

Manual workflows can’t keep up with this exponential growth, and legacy tools weren’t built for today’s global, subscription-based, usage-driven business models.

Global sales tax isn’t a challenge AI can solve alone. While automation speeds up routine tasks like data extraction, compliance demands precision, documentation, and defensibility.

Anrok pairs AI-driven efficiency with human tax expertise and robust infrastructure to deliver the accuracy and reliability modern businesses depend on. This hybrid approach ensures compliance at scale, without compromise.

The Series C funding will accelerate Anrok’s product partnerships, advance innovation in global sales tax automation, and expand R&D to keep pace with its rapidly scaling customers.

Powering compliance for some of the world’s fastest-growing companies, Anrok’s vision goes beyond automation to become the trusted global tax filing platform for governments and businesses alike.
