Close management platform Double raises $6.5m in Series A  

Double, a close management platform for accounting firms, has secured $6.5m in Series A funding led by Album Ventures.  

This latest investment brings Double’s cumulative funding to more than $12.5m.  

The company plans to develop new features, add to its engineering and customer success teams, and expand its network of partners in the accounting sector and technology industry. 

The round saw participation from Jack Altman, co-founder and CEO of Lattice, who is a returning investor, as well as Y Combinator.

Other previous investors include Mathilde Collin, co-founder and CEO of Front; Rahul Vohra, founder and CEO of Superhuman; and William Hockey, CEO of Column and previously CTO of Plaid. 

Double plans to allocate the funds towards further development of AI-based functions that aim to reduce repetitive work for accountants and improve financial reporting quality.  

The Double platform brings together client data, automates routine processes, and supports firms in completing their financial close tasks with both speed and accuracy. 

 More than 4,000 accounting and bookkeeping firms across North America currently use Double for month-end close activities. 

Over the last year, Double has expanded its workforce in engineering and sales. The company stated that it has more than doubled its size over this period.  

In October 2025, Double completed a rebranding initiative, changing its name from Keeper to Double.  

The company’s platform offers close management, which involves monitoring task progress, assigning responsibilities, and meeting deadlines for month-end activities.  

It includes automated processes, incorporating AI, support areas such as coding bank feeds, preparing journal entries, and compiling financial summaries. 

File review and quality control features automate the process of checking records and identifying discrepancies, decreasing time spent on manual reviews and supports accuracy. 

For client collaboration, the platform organises requests and document exchanges within a centralised system to minimise lengthy email correspondence. 

Double CEO and co-founder Ben Stein said: “Accounting is the heartbeat of every business, but accountants are still held back by tools built for an earlier era. 

“With Double, we’re helping firms focus on the high-value work that truly matters — judgment, insight, and client relationships – while automating the rest.”
