Merge

Merge is an integrations platform founded in 2020, headquartered in San Francisco with offices in New York and Berlin. It solves a recurring engineering burden for B2B software vendors: customers expect the product to sync with whichever HR, payroll, accounting, CRM, recruiting, ticketing or file-storage system they already run, and building and maintaining each connector individually is expensive.

Merge normalises hundreds of third-party systems into a single unified API with a common data model per category, so one integration effort unlocks the whole catalogue. The platform handles the full integration lifecycle — authentication, security, data syncing, webhooks, monitoring and ongoing maintenance — and provides Merge Link, an embeddable component that end customers use to authorise their own accounts. For banks and lenders this is a route to pull verified accounting and payroll data for underwriting without building each connector in-house.
