Unified API providers should grow with your needs. Merge diversifies across seven verticals, while Kombo focuses exclusively on HR Tech integrations.

This means Kombo's entire engineering team focuses on ATS integration challenges. Merge spreads resources thinly across multiple verticals.

Kombo has built 29 new ATS in the last year, Merge has built 7. But don’t just take our word for it - check recent changelogs to see where each vendor invests their engineering time.

Not all integrations are built equally. Complex workflows like conditional screening, writing assessment results back to the ATS, or automated stage transitions require deep API coverage.

Kombo supports advanced workflows across enterprise systems like Workday and Oracle. Merge’s customer have to rely heavily on passthrough requests for the same functionality.

For instance, Merge supports updating application stages for thirteen ATS. Kombo supports it for twenty-eight ATS. But don't just take our word for it - compare the coverage yourself in the docs or the overview below.

Integration challenges require both deep system knowledge and fast resolution times. Response speed without technical expertise and capacity leaves complex issues unresolved.

Kombo provides direct Slack access to the engineers who built your integrations. Merge routes tickets through general support staff.

Kombo has eight support engineers per 100 employees focused on ATS integrations. Merge has four support engineers per 100 employees across seven integration verticals.
