## Summary

Unified HR integration API connecting 100+ HRIS, ATS, and payroll systems through a single normalized API; $2M ARR within 18 months backed by YC competing with Finch and Merge for HR connectivity.

## Company Overview

Kombo is a Berlin-based unified HR integration API that enables B2B software companies to integrate with 100+ HR, ATS (applicant tracking systems), and payroll systems through a single standardized API — eliminating the need for each software company to build and maintain separate integrations for every HR system their customers use. Founded in 2022 and a Y Combinator graduate, Kombo serves 200+ customers including Fortune 500 companies, achieved $2 million ARR within 18 months of launch, and has raised funding from YC and other investors.

Kombo's unified data model normalizes data from systems like Workday, BambooHR, SAP SuccessFactors, ADP, Greenhouse, Lever, and 97+ others into a consistent schema — so a software company building on top of Kombo can read employee data (hire date, job title, department, compensation) or trigger actions (send offer letters, update employee records) across all supported HR systems through the same API calls. This is the "Plaid for HR systems" model: instead of each fintech integrating with each bank directly, Plaid provides a unified financial data API that most companies use instead.

In 2025, Kombo competes in the HR integration API market with Finch (similar unified payroll and HR API), Merge (broader data category unification including CRM, HR, and accounting), and Workato (enterprise integration platform) for the developer-friendly HR API connectivity market. The HR integration API category is growing rapidly as the HRtech stack has fragmented — companies may use Workday for HRIS, Greenhouse for ATS, ADP for payroll, and multiple other point solutions, requiring any software built for HR teams to integrate with all of these. The unified API model dramatically reduces the integration burden. Kombo's 200+ customers within ~2 years of founding demonstrates strong product-market fit in the developer community. The 2025 strategy focuses on expanding the HR system coverage, adding write-back capability (not just reading HR data but updating records), and growing enterprise software company customers.
