Founded in 2020, Double (formerly Keeper) delivers a unified workspace that centralizes client data, automates repetitive month-end close tasks, and facilitates real-time collaboration for accounting and bookkeeping firms. The cloud platform incorporates AI-powered workflows for bank-feed coding, journal entries, financial summaries, and file-review quality control. More than 4,000 firms across North America use Double to close books for hundreds of thousands of businesses every month, saving teams dozens of hours weekly. Over the last year the company has more than doubled its headcount and achieved 150% net-dollar retention, underscoring strong product-market fit. Recent rebranding to “Double” signals its mission to double accountants’ capacity, accuracy, and impact while preserving human judgment. With total funding now exceeding $12.5 million, the firm plans to accelerate product development, expand engineering and customer-success teams, and deepen AI capabilities. The company positions itself as the operating system for modern accounting practices, aiming to replace fragmented, manual spreadsheet workflows with a single source of truth.
