Kombo vs. Unified.to: w

June 4, 2025

Kombo is purpose-built for integrating HR, ATS, and payroll systems. Unified.to goes broader—delivering real-time, AI-ready data from 270+ APIs across 20 categories, including deep support for HR and recruiting platforms.

If you're building within HR tech, Kombo is deep and well-scoped. But if your product needs clean, fresh data across HR, CRM, and business systems—Unified.to gives you more breadth, less latency, and zero storage risk.

At a glance: Unified.to vs Kombo

Kombo offers deep HR coverage. Unified.to supports real-time, cross-domain pipelines with normalized schemas and no data storage.

Unified.to gives you:

Real-time updates (native + virtual webhooks)
270+ integrations across HR, CRM, ATS, Support, Marketing, and more
Normalized schemas with passthrough + raw field support
Database sync to Postgres, Mongo, MySQL
Zero-data architecture: no stored tokens or payloads
GenAI-ready tools: structured context for copilots and RAG

HR depth vs SaaS-wide breadth

Kombo focuses on HR tech: HRIS, ATS, and Payroll. It offers solid schemas and fast integration delivery inside that niche.

Unified.to supports 270+ APIs across 20 software categories:

HR (e.g., Workday, Personio, BambooHR, Gusto, ADP, HiBob, SAP SuccessFactors)
ATS (e.g., Greenhouse, Lever, Ashby, Workable, JobAdder, SmartRecruiters)
CRM, Support, Repos, File Storage, Calendar, and more

You get one platform for customer, employee, and system data—streamed in real time.

Real-time by design

Kombo polls source systems every few hours and stores data in its own database. It sends webhooks when batch syncs complete.

Unified.to is event-driven:

Native webhooks when available
Virtual webhooks for APIs without events
You get immediate updates via push—not polling jobs

Webhooks are configurable by object, field, and interval. You get structured events when data changes.

AI-native foundation

Kombo provides HR data to downstream AI workflows, but lacks native AI features.

Unified.to is designed for AI-native SaaS:

GenAI category with prompt/model objects
RAG-ready: pull context in real time from multiple APIs
Stream to LLMs, vector stores, or dashboards

Fresh, structured, cross-domain data for copilots and agents.

No data stored

Kombo mirrors customer data into its own infra. Raw data access requires enabling storage of unnormalized payloads—which can include PII.

Unified.to stores nothing:

No payloads or tokens cached
Credentials can live in your AWS Secrets Manager
Complies with data minimization principles

A leaner surface area for compliance-conscious teams.

Developer experience

Both platforms offer solid docs, SDKs, and a sandbox. Kombo provides a mock integration and "Kombo Connect" for auth.

Unified.to adds:

Declarative API + OpenAPI schemas
Fine-grained webhook config
Sandbox + tester account
Passthrough support and normalized schemas across every category

Faster time to value. More consistency across APIs.
