Today we announced Double’s $6.5M Series A funding. It’s an exciting milestone and certainly important, but the real story is why we’re building Double and why thousands of firms have joined us already.

For years, accountants have been promised automation while still drowning in spreadsheets, checklists, and email threads. Month-end close has stayed fragmented because most tools weren’t built for the pace or complexity of modern accounting. We created Double to change that. It's a platform that brings the close into one place and keeps up with the way accountants work.

We changed our name from Keeper to Double this fall, which better reflects the future we’re building toward. The fundamentals of accounting haven’t changed in 500 years, but the demands on accounting teams keep rising. Double is built on the rigor of double-entry accounting and designed to amplify human expertise so teams can meet those rising demands.

Our Approach to AI

AI is expanding what’s possible in accounting faster than anyone expected, and firms want to invest in tools that move them toward that future today. But vision alone isn’t enough. When AI isn’t grounded in real workflows, it creates a disconnect between people and the tools they’re meant to trust.

Our view is simple: when AI can make a task more accurate or efficient, it should, but it has to live inside a system designed around accountants. Human judgment will always matter. We’re building the AI-driven future of accounting on top of software that accountants rely on every month.

Customer Success Above Everything

More than 4,000 firms now run their close on Double, closing books for hundreds of thousands of businesses and saving dozens of hours each month. The success of our customers and their clients is what we’re most proud of and what drives us to do better every day.

This money helps us accelerate that work: expanding the platform, deepening our AI capabilities, and supporting the firms who count on us.
