Double Raises $6.5 Million Series A to Transform Accounting and Bookkeeping Workflows with AI-Driven Platform

Double, the New York City‑based software firm that provides a close management and practice management platform tailored for accounting and bookkeeping firms, has announced a $6.5 million Series A funding round, underscoring investor confidence in its vision to transform how accounting professionals work and close their books more efficiently. The financing — which brings Double’s total capital raised to more than $12.5 million — will be used to accelerate product development, expand engineering and customer success teams, and grow its partner ecosystem among leading accounting firms and technology platforms.

The Series A round was led by Album Ventures, a venture capital firm focused on early‑stage technology companies, with participation from returning investor Jack Altman, co‑founder and CEO of Lattice, and Y Combinator, the renowned startup accelerator. Earlier backers including Mathilde Collin, co‑founder and CEO of Front; Rahul Vohra, founder and CEO of Superhuman; and William Hockey, CEO of Column and co‑founder and former CTO of Plaid, also participated in the round.

Founded in 2020 and originally known as Keeper, Double rebranded in 2025 to reflect its expanded mission to “double” the capacity, accuracy, and impact of accounting teams by combining powerful software with AI‑enhanced workflows. The company’s platform centralizes client data, automates repetitive tasks, and streamlines the complex month‑end close process — enabling accounting professionals to work faster and with greater precision. Double’s tools are designed to help firms manage client communication, file reviews, and financial reporting in a single unified workspace that reduces manual checklists, scattered spreadsheets, and long email threads.

Double’s technology has seen strong adoption across the accounting sector. The platform now serves thousands of accounting and bookkeeping firms across North America, helping teams close the books for hundreds of thousands of businesses each month while saving significant time and improving accuracy. According to the company, its net‑dollar retention rate remains robust, signaling high customer satisfaction and strong product‑market fit among firms that have long struggled with inefficient and fragmented workflows.

In discussing the funding, Double’s leadership emphasized the importance of building software that augments human expertise rather than replacing it. By focusing on tools that empower accountants to automate mundane tasks — such as bank feed coding, journal entries, and financial summaries — the company aims to free professionals to focus on higher‑value work like strategic client advice and analysis. The new capital will also support continued investment in AI‑powered features that enhance productivity and reduce the time spent on routine tasks while maintaining accuracy.

Investor enthusiasm for Double reflects broader trends in software adoption within professional services, where firms increasingly seek purpose‑built tools that address long‑standing pain points in workflows. According to Album Ventures partners, Double’s focus on augmenting accounting workflows — rather than simply automating them — gives it a competitive advantage in an industry that has historically lagged in modern software adoption. The backing from seasoned founders and operators such as Jack Altman, Mathilde Collin, Rahul Vohra, and William Hockey further underscores confidence in the company’s leadership and growth prospects.

The $6.5 million funding comes at a time when demand for tools that streamline and modernize professional services workflows is surging. As accounting firms face increasing pressure to deliver faster and more accurate results, platforms like Double are becoming central to managing operational complexities and driving efficiency gains. With the Series A financing, the company plans to expand its market reach, deepen integrations with complementary technology solutions, and continue evolving features that address both the immediate and future needs of accounting professionals.

Double’s leadership has also highlighted plans to invest in its partner ecosystem, forging closer ties with technology providers and service partners that can help extend its reach and capabilities within the accounting landscape. By building a network of integrations and partnerships, Double aims to become an indispensable part of the modern accounting stack — a platform that not only supports core close management needs but also connects seamlessly with other tools that firms rely on daily.

As the company scales, its emphasis remains on delivering value through a combination of thoughtful product design, practical automation, and human‑centric workflow enhancements. With its recent funding boost and growing customer base, Double is positioned to play a significant role in reshaping how accounting and bookkeeping firms operate in an increasingly digital and AI‑driven world.
