getkombo.app ↗ ·Berlin ·Series A

Kombo builds a unified API that lets B2B software companies (HR, payroll, recruiting, and related SaaS platforms) offer integrations with 100+ third-party HRIS, ATS, payroll, assessment, and LMS systems through a single connection instead of building each one individually. Founded in 2022 in Berlin by four YC S22 alumni, the company has grown to 60+ employees across Berlin and New York, processes data equivalent to roughly 20% of Germany's workforce, and passed $10M+ ARR before raising a $25M Series A in February 2026.
