How Windsurf Scaled to $100M ARR with Just Two Finance Team Members

The Company

AI-powered growth at unprecedented scale

Windsurf builds AI-powered development tools that generate full-stack web applications from natural language prompts. As one of the leading AI code generation platforms (formerly Codeium), they serve developers and product teams who need to rapidly build and deploy sophisticated applications without extensive manual coding.

The company achieved extraordinary growth, scaling from $10 million to $100 million in ARR while maintaining an incredibly lean finance operation. Most remarkably, they accomplished this massive 10x growth with just two finance team members—one focused on finance and one on accounting—by leveraging Rillet's automated financial infrastructure. This operational efficiency allowed them to reinvest growth capital directly into product development and market expansion rather than administrative overhead, creating a significant competitive advantage in the fast-moving AI development tools market.

The Challenge

When rapid growth breaks your financial systems

Windsurf's finance team found itself overwhelmed by the volume and complexity of transactions. Their existing setup relied on QuickBook supplemented by extensive Excel spreadsheets for revenue tracking and reporting.

The system initially worked, but as transaction volumes grew to hundreds per month and enterprise contracts became more complex, manual processes became unsustainable. Custom terms in enterprise agreements were difficult to track accurately, and the team lacked real-time visibility into key metrics, such as ARR and customer retention.

The finance leader recognized the need for a comprehensive solution that could address their unique requirements: automated revenue recognition across multiple billing models, seamless integration with their existing sales systems, and real-time reporting capabilities for investor and board communications.

With plans to scale further, they couldn't afford to build out a traditional finance team structure. They needed technology that would enable a lean operation while maintaining accuracy and providing the sophisticated reporting their stakeholders required.

The Solution

Choosing integration over fragmentation

After evaluating various options, including point solutions that would require stitching together multiple vendors, Windsurf chose Rillet for its end-to-end approach. The decision came down to several key factors: comprehensive revenue recognition capabilities, native integrations with their existing tools, and a streamlined implementation process.

The implementation was notably smooth, taking approximately two months from start to finishThe implementation was incredibly smooth, taking less than two months from start to finish. The Rillet team handled the heavy lifting, including historical data migration and system configuration, requiring minimal intervention from Windsurf's finance team.

Key implementation elements included:

• Migration from QuickBooks with full historical data preservation
• Integration setup with Salesforce and Stripe
• Custom reporting configuration for board and investor materials
• Revenue recognition automation for both B2C and enterprise contracts

The hands-off nature of the implementation was particularly valuable given Windsurf's focus on core business operations during a critical growth phase.

The Results

10x Efficiency at scale

The transformation enabled Windsurf to achieve something rarely seen in the industry: managing $100 million in ARR with just two finance team members—one focused on finance and one on accounting.

Real-time visibility replaced manual Excel tracking for key metrics, such as ARR and customer retention. The finance team can now access live data instantly, enabling faster decision-making and more accurate investor reporting.

The platform's reporting capabilities proved especially valuable for board communications. Features such as the Executive P&L, ARR waterfall, and deferred revenue schedules provide investor-ready insights without requiring manual compilation.

Rillet manages approximately $50 million in monthly cash flow for Windsurf, maintaining accuracy while providing detailed visibility into performance drivers.

Close processes that previously required extensive manual work are now completed in under two weeks, with plans to achieve weekly closes as remaining manual processes are eliminated.

Scaling Without Compromise

Windsurf's finance operations now run with remarkable efficiency. The integrated approach eliminated the need for multiple point solutions, creating a single source of truth for all financial data. This consolidation improved accuracy while reducing the complexity that typically comes with rapid scaling.

The automated systems handle increased transaction volumes and complexity without degrading performance or accuracy. Features such as automated fixed asset tracking, depreciation schedules, and multidimensional reporting provide the sophisticated financial management typically associated with much larger organizations.

Most importantly, the solution scaled with their growth trajectory. Rather than requiring proportional increases in headcount, the platform enables continued expansion while maintaining the lean operational model that contributes to their competitive advantage.

By the Numbers

Building for Continued Growth

The results reflect a broader trend in modern finance operations: technology-enabled teams achieving outcomes that previously required significantly larger organizations. For fast-growing companies in competitive markets, this operational efficiency provides significant competitive advantages, enabling continued investment in core business growth rather than administrative overhead.
