Between HR and Technology translators are needed
talessio is a Cornerstone implementation partner and HR tech specialist based in Tübingen. We support companies across the DACH region and worldwide – from platform strategy through Cornerstone rollout to in-house products that extend the standard.
What sets us apart
Four principles that show in every project
Not a mission statement on the wall, but a way of working — verifiable in our projects and our products.
We question standards.
Where the Cornerstone standard reaches its limits, we deliberately build around it — with configuration paths beyond the out-of-the-box, with integrations, or with our own Micro Apps. Three of these constructs are now on the market as talenttrends products.
We think about platforms across their lifecycle.
Selection, implementation, integration, operation — and everything that happens between quarterly Cornerstone releases. Many of our client relationships have lasted for many years, because neither we nor our clients move on after go-live.
We build for adoption, not for spec sheets.
A platform that fits the requirement spec but gets in the way of daily work has failed. That is why we support roll-outs with change management and design interfaces that HR teams can use without training.
We translate between HR, IT and business.
Three domains, three languages, three success criteria. We are at home in all three — and make sure decisions don’t get lost between the data model and the process map.
The idea
What’s behind talessio
The name talessio combines Talent and accessio – growth.
Because we are convinced: companies don’t grow through structures, processes or technologies. They grow through people.
That is why we help companies make talent visible, develop it and retain it. And that is why we live by the same principles ourselves: trust, responsibility and the freedom to flourish.
Growing talent. Moving companies forward.

Our own products
Where consulting meets the limits of the standard, products emerge
talenttrends grew out of many years of Cornerstone practice — a product suite that starts exactly where the Cornerstone standard ends: with data, integrations and specialised functional requirements.
talenttrends Data Hub
Replicated Cornerstone data for reporting, BI and AI use cases — without reporting API limits.
talenttrends Integration Layer
A clean interface layer between Cornerstone and IDP, ERP or specialist systems.
talenttrends Micro Apps
Functional apps for exactly the requirements that no Cornerstone module covers.
