“Can an AI-native month-end close platform become the operating system for every accounting firm and internal finance team on QuickBooks/Xero?”
Founded 2020 as Keeper, a month-end close and practice management platform for bookkeeping firms working in QuickBooks Online and Xero. Went through YC S21 and expanded from a bookkeeping workflow tool into a broader accounting operating system with a tax suite, client portal, e-signatures, and AI-driven transaction categorization. Rebranded to Double in October 2025 after losing a trademark dispute; product and team unchanged. The company is a pure vertical SaaS play — Jensen Technology, Inc. dba Double — with no embedded financial products of its own; its 'financial' exposure is limited to reading ledger data via QuickBooks/Xero APIs and processing subscription payments via Stripe.
Keeper.app processes payments through Stripe.
Keeper.app integrates with QuickBooks Online, Xero, NetSuite, Sage Intacct, Zapier, Gmail and Ping.
The Embedded Finance Index 2026 maps 3 layers in Keeper.app's stack: Payments / PSP (Stripe); Unified APIs (QuickBooks Online (native), Xero (native), Sage Intacct (native) and NetSuite (native)); Accounting (QuickBooks Online, Xero, NetSuite, Sage Intacct and 3 others).
Keeper.app was founded by Ben Stein and Kenny Song and is founded in 2020, headquartered in Austin, Texas, United States.
