At Volition, we partner with founders building enduring, mission-critical infrastructure in large and evolving markets — and Kombo exemplifies that vision. We are proud to have led Kombo’s $25 million Series A. Interoperability is the defining challenge of the modern workforce ecosystem. With HR technology rapidly proliferating and people data increasingly fragmented across systems, Kombo is building the infrastructure layer that enables this ecosystem to function — providing a unified, trusted backbone for the global flow of workforce data.
Fragmentation in HR Tech Has Turned Integrations Into a Bottleneck
Managing the employee lifecycle from hire to retire runs on a complex and highly fragmented ecosystem of HR technology solutions. From applicant tracking systems (ATS) and HRIS platforms to payroll, IT, benefits, and compliance tools, companies rely on dozens of systems to manage candidates and employees. For HR tech vendors, enabling seamless data flow across these systems is no longer a “nice to have” — it is essential to delivering a competitive product experience.
Yet building and maintaining integrations is a burdensome process. Each system has its own APIs, data schemas, edge cases, security requirements, partnership protocols, and ongoing maintenance needs. Engineering teams are forced to spend months building one-off integrations that distract from core product development and innovation. As companies scale, this problem compounds, slowing customer onboarding, increasing technical debt, and creating real go-to-market friction.
As HR software continues to proliferate globally, the need for a scalable, trusted integration layer has become mission critical
A Mission-Critical Infrastructure Layer With Clear ROI
Enter Kombo, a company solving this problem by providing a unified API purpose-built for HR, payroll, and IT integrations. Instead of building and maintaining dozens (or hundreds) of direct integrations, customers integrate with Kombo once and gain access to more than 200 (and counting) pre-built integrations across ATS, HRIS, payroll, and adjacent categories.
The value proposition is immediate and ROI tangible. Customers dramatically reduce engineering time dedicated to integrations, accelerate partner onboarding from months to weeks or days, and eliminate the ongoing maintenance burden that comes with supporting a fragmented vendor landscape. Once implemented, Kombo becomes deeply embedded in customers’ core workflows, effectively serving as the integration backbone behind their product.
This mission-critical positioning is reflected in Kombo’s performance. The company has achieved strong capital-efficient growth, high gross margins, and best-in-class retention, with customers consistently describing Kombo as “Stripe-like” infrastructure — once installed, it is not something lightly ripped out.
Kombo’s Product-First Roots
Kombo was founded in 2022 by Alex Kübel and his co-founders, a deeply technical team that thrives on solving hard problems with elegant technical solutions. From the outset, the team took a deliberate, verticalized approach, focusing exclusively on HRIS and ATS use cases rather than pursuing a broad, horizontal integration strategy.
That focus has proven to be a key differentiator. By going deep into HR-specific data models, workflows, and edge cases, Kombo has built integrations that customers consistently describe as more reliable and complex than alternatives, supported by a team of subject matter experts available 24/7. The company has earned a strong reputation for product quality, reliability, and domain expertise, which has manifested in exceptional customer feedback and retention.
Since launch, Kombo has scaled to hundreds of customers globally, reached meaningful ARR with strong unit economics, and is now doubling down on its product and go-to-market capabilities to capitalize on the largely untapped market opportunity.
Why We’re Excited to Partner With Kombo
When we first met the Kombo team, we were impressed by the clarity of their vision and disciplined execution. Kombo is building foundational infrastructure in a market where reliability, trust, and domain expertise are paramount.
We believe Kombo’s verticalized strategy, combined with its growing integration coverage, opinionated data layer, and strong customer relationships, positions the company to become the single source of truth for HR integrations. Over time, this foundation creates natural expansion opportunities into adjacent use cases, new customer segments, and agentic workflows that further increase the platform’s strategic importance.
Just as importantly, Alex and the team possess a rare combination of technical rigor, customer obsession, and capital efficiency. As Kombo scales, we are excited to partner closely with the team and support them as they enter the next phase of growth — expanding market reach, strengthening go-to-market execution, and continuing to invest in a product customers truly depend on.
