# Product Capabilities & Clarifications

> _Last updated: March 30, 2026._

There are many misconceptions shared about what Kombo does and how it works. This page provides the facts, with links to official docs and case studies.

## Myth 1: Does Kombo store data?

### Answer

Yes. Kombo stores data to deliver faster API responses, critical features like
filtering, change tracking, deletion tracking, and reliability during upstream
outages. This approach has become the preferred option for companies connecting
enterprise clients with high-volume, fast-moving data.

### Why this matters

* **Performance:** Kombo uses local caches and “updated-after” timestamps to
  fetch only what changed since the last sync. Customers avoid building complex
  caching logic and reduce infrastructure load by up to 95%.
* **Advanced features:** Cached data powers real-time webhooks, multi-field
  filtering, comprehensive change and deletion tracking, and detailed error
  reporting during syncs to identify issues quickly.
* **Resilience:** If upstream systems like Workday or BambooHR experience
  outages, Kombo continues to serve the latest cached data. Applications keep
  running while Kombo retries in the background.

## Myth 2: Is Kombo focused on European integrations?

### Answer

No. Kombo has the widest ATS and HRIS coverage in the U.S., with most of its
customers based there. It has built out the widest ATS and HRIS coverage for the
U.S., integrating with systems like iCIMS, UKG Pro, Fountain, ADP Workforce Now,
Paylocity, and many more.

## Myth 4: Does Kombo support real-time data sync?

### Answer

Yes, Kombo combines native webhooks where supported with high-frequency delta
syncs for systems that don't offer webhooks. Especially for high-volume use
cases, this is the preferred approach by end-customers, as it allows for
processing operations near-real time without introducing a lot of load to the
system.

### Answer

Yes. Kombo provides webhook support for integrating real-time events.

## Myth 6: Do end customers want to connect with a middleware like Kombo?

### Answer

Yes. Kombo has connected over 20,000 end customers and some of the most
security-conscious Fortune 500 companies, including some of the largest strategy
consultancies, automotive, manufacturing, and retail companies worldwide.

and a passthrough API for integration-specific features and edge cases.
