Anrok has raised $55 million in Series C funding led by Spark Capital, with participation from Sapphire Ventures and our existing investors Khosla Ventures, Sequoia Capital, and Index Ventures. This brings our total funding to over $100 million.

The pace of innovation deserves better infrastructure

"Knowing our tax compliance automatically scales with our billing allows us to focus on product development without diverting engineering resources to tax complexity." —Connor Solimano Business Operations and Strategy at Cursor 

The relentless pace and innovation of our customers is what fuels our team at Anrok. Modern companies are building the future at an unprecedented rate—launching groundbreaking products, pioneering new business models, and reaching global audiences instantly.

By trusting our team to navigate the complexities of tax compliance and financial risk, they're free to focus on what they do best, transforming industries and driving innovation forward.

Today, over 3,000 finance leaders trust Anrok with their global tax compliance. Companies like Anthropic, Cursor, and Notion rely on us across 100+ countries where digital products are taxable. Thanks to our team’s dedication to building a solution for modern, fast-growing businesses, over 40% of the Forbes AI 50 have chosen to work with Anrok.

So for us, it’s not about the numbers, it’s what those numbers have delivered for our customers:  

• Teams saving 90% of their time on sales tax every month
• Engineers who can focus on product instead of tax complexity
• Finance leaders who sleep better at night knowing compliance is handled

That's exactly the outcome Anrok is built for.

Why tax compliance is exponentially hard

Here's what we've learned from analyzing over $1.4 billion of monthly revenue: companies experience a 47x increase in filing requirements as they scale. Annual filings jump from 2 at under $1M revenue to 94+ filings at $50M+ revenue. Meanwhile, the percentage of revenue subject to taxation more than doubles from 20% to 51%+ as you expand globally.

Manual processes simply cannot keep up with this kind of exponential complexity. And legacy tools weren't built for the way modern businesses operate (recurring revenue, usage-based billing, global-first distribution).

Our approach: Human expertise meets AI efficiency

"Global sales tax compliance has been broken for too long, it's one of those problems that gets exponentially harder as companies scale. Anrok has built the first solution that actually scales with modern businesses. They understand that commerce is global. You need to deeply understand local requirements to support modern commerce. We're excited to back this team as they become essential infrastructure for global businesses." —Yasmin Razavi, General Partner at Spark Capital

Global sales tax isn't a problem you can fully automate with AI alone. While AI excels at routine tasks like document extraction, tax compliance is deterministic and requires thorough documentation for audit defense.

Our approach combines AI for workflow efficiency with human tax experts and reliable infrastructure for accuracy and assurance. It's this hybrid model that lets us deliver the coverage and reliability modern businesses need.

What we're building next

This Series C funding accelerates our product partnerships, fuels innovation in global sales tax compliance automation, and supports expanded R&D to meet the pace of our customers.

Because Anrok powers compliance for some of the fastest-growing companies in the world, our vision extends beyond automation. We're working to become the trusted tax filing services platform for all governments worldwide.

To our customers: this milestone is yours as much as it is ours. Thank you for trusting us with something as critical as tax compliance. Your feedback, your partnership, and your success drives everything we do. Stay tuned for a lot more!
