“Can one unified API become the default integration layer for every vertical SaaS and B2B fintech that needs accounting, HRIS, and CRM data?”
Apideck was founded in 2019 in Antwerp as a unified API platform to normalize the data models and authentication flows of 200+ downstream SaaS connectors across categories like Accounting, CRM, HRIS, ATS, File Storage, Ecommerce, and Issue Tracking. Its Accounting API has become the flagship — pitched at vertical SaaS, B2B fintech, banking, lending, and taxtech buyers who need to sync bills, invoices, bank feeds, and financial statements across QuickBooks, Xero, NetSuite, Sage, and 47+ other ledgers. In 2024 it raised a $7.5M Series A, and in 2026 it added an MCP Server to expose its unified APIs to AI agents, positioning itself as integration infrastructure for both human product teams and autonomous agents.
Apideck processes payments through Stripe.
Apideck integrates with QuickBooks, Xero, NetSuite, Sage, Sage Intacct, Exact, MYOB and Microsoft Dynamics 365 Business Central.
