Kombo

Unified API for HRIS, ATS, payroll

Overview

Kombo provides a unified API platform that acts as an infrastructure layer for the future-of-work sector, connecting HRIS, ATS, and payroll systems through a single integration point. Developers connect to Kombo's API, which standardizes data models so apps can read and write employee data, job applications, payroll details, and related information across many systems. Compared with competitors, Kombo centralizes integrations instead of building separate connectors for each system and offers strong developer tooling, positioning itself for mid-market and enterprise customers across Europe. Its goal is to remove the resource burden of multiple point-to-point integrations by expanding its catalog of connected systems and delivering scalable, reliable integration as a service.

Workera partners with Kombo to deliver verified skills data across 200+ HRIS and ATS platforms through a single connection.

Workera partners with Kombo to deliver verified skills data across 200+ HRIS and ATS platforms through a single connection. One integration writes verified capability results into the systems of record where hiring, internal mobility, and upskilling decisions are actually made. Workera, the AI agents company powering the skills intelligence layer for the enterprise, announced a partnership with Kombo that delivers verified skills data into more than 200 HRIS and ATS platforms through a single connection. Workforce capability data is scattered across applicant tracking, learning, and HR systems, and most of it is self-reported, inferred, or stale. Only 33% of business leaders believe their current talent data is sufficient to make informed decisions, according to Gartner, a gap that creates roughly a 20% drag on operational efficiency. As enterprises race to plan for AI, that missing signal has real consequences: BCG finds that 80% of AI initiatives fail to deliver value because leaders mistake tool access for actual workforce capability. "Every talent system runs on data and could work dramatically better with data that's actually trustworthy," said Kian Katanforoosh, founder and CEO of Workera. "Thanks to our partnership with Kombo, we're now surfacing Workera's verified skills data across all of those systems. Recruiters, line managers, and enterprise leaders keep working in the tools they already know best, now connected to Workera and its best-in-class data. That's the vision: one verified signal, available everywhere a talent decision gets made." Through the single connection with Kombo, Workera pulls employee and candidate lifecycle data in and pushes verified capability results back out. On the HRIS side, the integration syncs employee records daily to add, update, and deactivate users automatically, uses HRIS attributes to enroll employees into the right development programs, and writes verified skill ratings natively onto employee profiles, normalized to each platform's own scale and mapped to the customer's taxonomy with admin approval before anything goes live. On the ATS side, advancing a candidate to the assessment stage triggers the right Workera assessment automatically, and status, score, and pass/fail results land back on the candidate record. Purpose-built integrations carry the same verified signal into an LMS and deep-link learning recommendations to the exact content that closes a verified gap in libraries. What sets the approach apart is the nature of the signal itself. Competing platforms infer skills from resumes and job titles or label them from work artifacts. Both are guesses, and self- or manager-confirmed skills are opinion, not proof. Workera verifies capability through measurement and delivers that fact as a first-class skill rating the platform understands, not a file someone has to export, map, and upload. The posture is additive by design: Workera strengthens the HRIS, ATS, and learning systems an enterprise already runs rather than replacing them. Authentication stays with Kombo, which operates as a subprocessor under the customer's data-privacy agreement, so Workera never stores raw HRIS credentials. Callbacks are cryptographically signed and verified, and platforms use OAuth 2.0 flows. Workera itself is SOC 2 Type II, ISO 27001, and ISO 42001:2023 certified, and GDPR and CCPA compliant. "Enterprises shouldn't have to choose between trustworthy skills data and a stack that's realistic to maintain," said Alexander Kuebel, CEO and Co-Founder at Kombo. "Our unified API lets Workera reach hundreds of HRIS and ATS systems through one connection, so verified capability data reaches the systems companies already run without a point-to-point build for every platform."

Workera partners with Kombo to integrate verified skills data across 200+ HR and recruitment platforms

Workera has partnered with Kombo to integrate verified skills data across more than 200 HRIS and ATS platforms through a single connection. The partnership addresses a critical gap: only 33% of business leaders believe their current talent data is sufficient for informed decisions, according to Gartner. The integration automatically syncs employee records, writes verified skill ratings onto employee profiles, and triggers assessments for candidates. Unlike competitors that infer skills from CVs or self-reported data, Workera verifies capabilities through measurement. Kombo's unified API eliminates the need for point-to-point integrations for each platform. The system is SOC 2 Type II, ISO 27001, and ISO 42001:2023 certified, and GDPR and CCPA compliant. Most integrations can be enabled the same day.
