AI-Powered HR Knowledge and Employee Development Platform
A German company kept losing important knowledge every time an experienced employee retired. The platform saves what people know, turns it into training, and shows who is ready to take over which role.
Understanding the problem
Most of the company's knowledge was in people's heads, not written down. The little that was saved sat in folders no one opened. New employees spent months relearning things, and making training was slow and expensive.
Solution overview
Employees record what they know, and the platform makes it searchable
One recording becomes a full training module: script, video, audio, and a quiz
HR builds step-by-step learning paths that track each person's progress
The platform maps skills, shows gaps, and flags who is ready to move up
Compliance, GDPR, and audit logging are built in
How we engineered
Multi-tenant from day one, so many companies share one platform with their data kept separate
40+ data models built on a clean, modular structure that's easy to maintain and extend
More than a dozen AI models connected through one gateway, with automatic switching if a provider goes down
A RAG knowledge base so the AI answers from the company's own documents, with citations
Role-based permissions and a record of every action, built for German data rules
The Impact & Results
Knowledge stays in the company when people leave
Training that took weeks now takes hours
HR can see skills, gaps, and successors in one place
The platform supports many companies at once, so it grows without extra work
