Double, a modern accounting platform built to streamline and automate the month-end close for thousands of firms, announced a $6.5M Series A funding round. The company develops an AI-supported system designed around double-entry rigor and real accounting workflows, enabling teams to manage the entire close in one place and reduce reliance on fragmented spreadsheets and email chains. Double recently rebranded from Keeper to better reflect its long-term vision of combining accounting fundamentals with advanced automation.
The platform now supports more than 4,000 firms, helping them close books for hundreds of thousands of businesses and saving significant operational time each month. The new funding will accelerate platform expansion, strengthen AI capabilities, and enhance support for accounting teams. “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,” said CEO and founder Ben Stein.
