About oneLake - Our story
In summer 2020, Thomas and Dennis met again after a long time in a small bar in Düsseldorf. From a conversation about their shared time in consulting, the idea emerged to found a company together – with a clear vision:
"To enable more people in companies to make decisions based on data."
Over many years, we experienced as consultants how differently companies approach their data. Again and again, we encountered the same questions – and just as often, we saw how tedious and fragmented the path to the right answers can be. Different systems, data silos, and complex preparation processes often led to delays and frustration. This is exactly where oneLake comes in.
"We want to democratize data access and eliminate bottlenecks in data preparation and provisioning."
A central element is our AI component oneAgent, which ushers in a new era in dealing with corporate data. oneAgent enables intuitive and efficient use of data – without deep technical knowledge. We are supported by a strong team of experts from various disciplines. Together, we share the conviction: Everyone can be a Datastar!
"Our goal is to reduce the requirements backlog and enable companies to make data-driven decisions with ease."

OUR OWN AI TECHNOLOGY
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 real in-house expertise, not purchased know-how. Our developers, data scientists, and AI engineers work on advancing the platform every day.
In a world dominated by US American tech giants, oneAgent is a European alternative – developed in Germany, hosted in Europe, with a clear focus on data protection, data sovereignty, and the requirements of European companies.
Whether oneAgent is used is something we decide together with you. If it fits, our consulting becomes not just a project, but a sustainable solution that your team can use every day.

OUR VALUES
We're a team that cares deeply about clarity, trust, and building things that genuinely help people do better work
What drives us
We're motivated by solving real problems and doing the work properly.
Clear goals, shared responsibility, and respect for the people who use what we build guide every decision we make.
Everyone can be a Datastar
We've worked inside teams, dealt with messy systems, tight deadlines, and unclear data.
That experience shapes how we think, how we design, and how we collaborate - practical first, always.
We believe in accessibility, not gatekeeping
We believe good work shouldn't depend on knowing the right jargon or having a technical background. Our mindset is simple: if something is useful, it should also be understandable.
Trust over hype
We care about accuracy, transparency, and setting the right expectations.
Building trust in our work, our thinking, and our relationships matters more to us than quick wins.
We fit into real-world workflows
We respect how teams already work.
Instead of forcing new processes, we aim to support existing ones and improve them step by step.
