“I make dealing with IT law and data protection easier for you.”
I have been working in IT law and data protection for many years – an area that constantly brings with it new requirements. My aim is to create clarity, make complex issues tangible and develop solutions that are both legally and strategically convincing.
Dear Jens, what does K.’s promise “To make it simple, but significant.” mean to you? What added value do you offer your clients?
“You explained it in such a way that I really understood it for the first time” – I often hear this from clients, and it means the world to me. Because then I have managed to make complex legal challenges as clear and understandable as possible – without losing any depth or precision. This orientation in a world that is often characterized by excessive demands due to technical jargon and countless options is my added value for my clients.
Recognized expertise – I have received several awards for my work
In addition, I was regularly quoted in the most important German media such as the FAZ, Süddeutsche Zeitung and SPIEGEL on data protection issues.
“Outstanding professional quality, astute, meticulous, clear, advises holistically and tactically, thinks quickly and comprehensively about a problem from the client’s perspective.” (Issue 2024)
“Jens Nebel has acquired a very wide-ranging, remarkable expertise in IT law. He fully understands the relevant technical contexts and can then classify them with legal accuracy. He is tough on the matter, but does not miss the opportunity to reach an amicable settlement.” (Issue 2025)
“Jens Nebel is a good negotiator and thinks very strategically.” (Issue 2025)

What was a milestone in my career?
“A particular milestone was my work as a defendant’s representative in one of the most important data protection proceedings before the European Court of Justice.”
Strategically clear advice for digital projects
I support companies in the implementation of complex projects. My aim is always to find simple, clear solutions that support your individual goals.
Software development projects often come with surprises – for both clients and providers. From my experience supporting many such projects, I’ve learned that smart contract design can prevent many points of friction in advance, ensuring clarity for both parties.
Outsourcing is a matter of trust. Few scenarios place an IT client in a position of greater dependency. This makes it all the more important to have the courage to demand and enforce clear contractual terms.
Using data is anything but straightforward. The regulation of the digital economy places significant demands on data users. That’s why it’s essential to know the right legal options — or to know someone who does.
