Merge, an API integration service focused on HR and accounting systems, raised a $55M Series B led by Accel, says over 2,500 companies use it in their SaaS apps
The funding environment may have changed in recent months, but startups with strong fundamentals are still able to raise.
Context & Ripple Effects
Merge's $55M Series B is another data point in Accel's habit of leading the Series B for infrastructure-style startups: the firm did the same for banking-as-a-service player Unit with its $51M Series B in mid-2021, and again years later for cloud-spend optimizer PointFive's $60M Series B.
The round also lands against a colder market — the coverage notes that while the funding environment shifted through 2022, startups showing real usage fundamentals still raise. Merge's claim of 2,500+ companies embedding its HR and accounting integrations inside their own SaaS apps is exactly the kind of traction being priced.
First-order effects
- Merge gets fresh capital to widen its catalog of HR and accounting integrations, and Accel adds a second embedded-fintech-adjacent bet to a portfolio that already includes Unit.
- The 2,500+ companies already shipping Merge-powered integrations get a better-resourced vendor behind a component their own customers see.
Second-order effects
- SaaS product teams weighing build-vs-buy on integrations face a stronger argument for buying: a funded specialist maintaining HR and accounting connectors removes work from their roadmaps.
- Rivals in the integration-middleware space must compete against a category leader with fresh Series B capital, pushing pricing and connector-coverage competition rather than feature parity alone.
Third-order effects
- If usage-based adoption keeps compounding, integration plumbing consolidates into a standard layer of the SaaS stack — a handful of funded intermediaries sit between most business apps and the systems they connect to, the way payment APIs did earlier.
The trend: Investors keep funding API-middleware specialists that let SaaS products offer deep integrations as a feature instead of an engineering project, with Accel repeatedly leading those Series B checks.
