# Ingest users
## Ingest user data from any source.



Krenalis lets you ingest user data from any source — including real-time event streams, mobile and web applications, backend systems, databases, files, and SaaS platforms. All inbound user records enter a unified ingestion pipeline where Krenalis validates payloads, applies your profile schema, and prepares data for profile unification.

This process forms the foundation for building accurate, deduplicated, and up-to-date customer profiles that power analytics, segmentation, personalization, and activation across your entire stack.

## How ingestion works

1. **Ingest user data**\
   Import event-based user data or batch data from databases, files, and SaaS applications using a typed schema.

2. **Validate and enrich**\
   Validate incoming records against your schema and enrich them with relevant context to ensure accuracy and completeness.

3. **Harmonize**\
   Normalize and transform user data so it aligns with your profile schema and is consistent across all sources.

4. **Load into your data warehouse**\
   Stream identities to your warehouse in real time, ready for analytics, reporting, and AI workloads.
