Accounting New York, NY 51–200 employees Privately Held

Double integrates with QuickBooks Online and Xero to automate month-end close workflows for accounting firms. The tech stack is a modern full-stack JavaScript build (React, Node.js, TypeScript, PostgreSQL on AWS), paired with HubSpot and Salesforce for sales operations—a typical pattern for a B2B SaaS product scaling from product-market fit into sales and customer expansion. The project list is almost entirely sales and customer success focused (prospecting, onboarding, account expansion, demo scheduling), with hiring split across sales, engineering, and support, indicating an early-stage growth company in sales-execution mode.
