About Datarails
Datarails was founded in 2015 with a contrarian thesis in a market obsessed with replacing Excel. Research shows that 99 percent of financial professionals spend more than three hours a day in spreadsheets, and 89 percent of Gen Z and Millennial finance workers believe Excel will remain as important or more important over the next decade. Every major FP&A vendor told finance teams to abandon Excel for a new interface. Datarails made the opposite bet: build technology that enhances Excel rather than competes with it.
Building bidirectional integration between Excel and a governed cloud database required years of engineering work on data integrity, version control, and real-time synchronization. Investors viewed Excel enhancement as a limited market, forcing the founders to bootstrap. Finance teams had accepted manual consolidation as inevitable, and Datarails had to prove that powerful FP&A capability could sit inside the tools finance already knew, without retraining or the six-month implementation cycles that defined the category.
That thesis has since reshaped the fintech landscape for the Office of the CFO. In 2026, Datarails launched FinanceOS, the first governed financial data layer built for the AI era. FinanceOS connects ERP, CRM, HRIS, and 400 plus other sources into a single finance-validated model in as little as one day. Via Model Context Protocol, it serves clean, audit-ready data to any AI tool on the market, including Claude, ChatGPT, Gemini, Lovable, and Cursor. Rather than selling a fixed workflow, Datarails now sells infrastructure: the data layer that makes any AI tool enterprise-grade for finance.
The launch galvanized the fintech community. Fortune framed it as a bold bet that the traditional FP&A tools Datarails helped pioneer are now obsolete thanks to AI. Accounting Today covered the launch as the birth of an entirely new category in financial technology. The Secret CFO described the 175 million dollar funding total as a massive market bet on FinanceOS, arguing the path to a high-performance finance function runs through integration rather than replacement. Fintech commentator Linas Beliunas wrote that the real bottleneck in finance software has shifted from modeling to infrastructure.
The market has validated the thesis. Datarails closed a 70 million dollar Series C in January 2026 led by One Peak, bringing total funding to 175 million dollars. Revenue grew 70 percent year-over-year in 2025, with more than half coming from products launched in the prior 12 months. Customers report 80 percent reductions in reporting cycle time. Tangoe cut month-end reporting from three weeks to three days. La Fosse answers variance questions in 10 seconds that previously took two hours.
Datarails is also shaping the fintech workforce conversation. The CFO Office 2.0 report, published by Datarails in 2026, found that one in three finance roles now requires AI skills, up from one in four a year ago, with FP&A roles leading at 43 percent. Datarails also earned a place on the Inc. 5000 ranking of fastest-growing private companies in the US and ranked 113th on the Deloitte Technology Fast 500.
