Founders & story · from Merge’s own dossier

Merge launched in 2020 as a unified API for HRIS/ATS/Accounting/CRM/Ticketing/File Storage, aimed at B2B SaaS companies who wanted to ship customer-facing integrations without building each connector themselves. By 2026 the company has repositioned around AI: the same unified-integration muscle now powers Merge Agent Handler (giving AI agents authenticated tool access) and Merge Gateway (LLM routing and cost control). Merge is not an embedded finance company — it is embedded-finance-adjacent as a data pipe into the accounting / HRIS / financial services stacks its customers build on top of.
