What sets oneLake apart from other data consultancies
Many consultancies talk about AI. We develop it ourselves. With oneAgent, we have built our own AI-powered self-service data platform - with genuine in-house expertise from our team of developers, data scientists, and AI engineers.
oneAgent is a European alternative to US tech giants: developed in Germany, hosted in Europe - with a clear focus on data protection and data sovereignty.
Whether oneAgent is deployed is something we decide together with you. This turns our consulting into a sustainable solution that your team can use daily.
What's it like... if your data could answer? Experience how easily you can ask complex questions with oneAgent and act immediately.
