Legal competences radically redesigned

We understand the complexities of navigating the rapidly evolving landscape of emerging technologies and exponential growth. To effectively address the unique challenges of this environment, lawyers are required to embrace new skills and competences that were previously unknown and unexpected in the legal industry.

We never stop being curious, creative, disruptive and solution-oriented, always pushing the boundaries of what is possible and exploring new, untested avenues to provide viable business solutions and the best possible outcome for our clients. At Kassailaw, we don't just complete legal tasks at your command. We always strive to stay ahead of the curve, anticipating and addressing areas where current laws are yet to provide clear answers.



Quantum computers. Flying cars. Medical operations executed by robots. Chips implanted into humans. Genetic editing. AI generated art. The sci-fi world is becoming reality at an exponential speed and we have been supporting this change in Europe for more than a decade. As technology lawyers, we couldn’t feel more alive by the constant challenges of this revolution.

At Kassailaw, we offer a breadth of expertise across a diverse range of technological areas. With us, you don't have to spend time explaining the intricacies of your technology – we are already familiar with it.



Our integrated mentoring approach offers a distinctive blend of legal support and entrepreneurial guidance, specifically designed to provide a comprehensive and well-rounded support system for innovative companies.

At KassaiLaw, we recognize that the success of an innovative company goes beyond legal compliance and protection. We understand that legal considerations are just one piece of the puzzle, and that startups also need guidance on other important aspects of their business. That's why our holistic mentoring approach goes beyond traditional legal services, offering a wider range of entrepreneurial mentorship that can help our clients navigate the complex and ever-changing landscape of the tech industry. With our integrated mentoring approach, startups can focus on what they do best – innovation – while we take care of the rest.


Innovation and technology do not believe in borders. Neither do we.

At KassaiLaw, we believe that the world should be as borderless as you want it to be. We recognize the global impact of technological advancements and the importance of providing solutions that are not confined by geographical borders. Our innovative approach also breaks down the intellectual barriers of the legal industry, enabling us to serve clients across the EU and beyond with a comprehensive range of services tailored to tech businesses. Therefore, we understand the complexities of different business environments and cultures when going international, and we are dedicated to providing you with the guidance and support you need to succeed in an increasingly interconnected world, on a global scale.


Startup and entrepreneurship specialisation – because we care
Not a marketing line. Our everyday business.

Our roots in the startup industry run deep. We have been serving this sector long before it became popular, and we are truly dedicated to our clients and their vision for the future. Our commitment to disruption and innovation in our own industry sets us apart from other law firms many of whom simply ride the trend without truly understanding the needs of innovative companies.

Many firms may claim to serve startups, but all too often, these cases are passed down to junior associates and paralegals, resulting in a lower quality of service.

At KassaiLaw, we understand that every great innovation starts with an idea, and we are committed to providing premium services to all innovators, no matter the stage of their company.


Innovative solutions with a personal touch
Innovation and technology do not believe in borders. Neither do we.

We couldn’t serve the tech industry so successfully and efficiently if we weren’t dynamic, energetic, enterprising and natural. Simply different. Our informal and straightforward approach sets us apart in the realm of the law firm experience and allows us to build strong, personal relationships with our clients. Rather than being seen as distant advisors, our clients view us as a trusted member of their internal team and appreciate the collaborative nature and the creative solutions that come from such a working environment.

We place a high value on the personal touch in our work and have deliberately cultivated a company culture that supports this approach. We understand that business is ultimately about people, and our focus on building strong personal connections allows us to provide the highest level of service to our clients. Because that is what innovation deserves.

I saw the changing needs of our times   The needs of radically reimagining and fundamentally redesigning the law firm experience for innovative companies. To break down the borders of the legal industry.   Resonating to these visions, it was inevitable that the area of innovation and technology found me very early and have not let me go since. I believe that tech is one of the bravest, most dynamic and forward-looking business industries of our times. One with so many brilliant visionary minds, one in which you can literally shape the future every single day wherever you are on the planet, with the united goal of progress.    At first, very few people understood it. Even less supported it. Yet, one thing was clear from the very beginning: I saw no other way. A law firm can indeed be progressive, disruptive, unconventional and forward-thinking.    Growing organically and independently, more and more like-minded and motivated experts have been joining me to continue building together what KassaiLaw has become today and will become in the future.    As in case of any innovation, the journey of KassaiLaw is built on our unquestionable faith in possibility, not in certainty. After our professional history of a decade, both because of our clients´ and our own dreams, we can fairly say:  Yes, its possible!   In the end, we all want to live in a better world. So we had better create it together.

“Is your team the dream team? How much percentage should each founder get?” One of the core ingredients to success is the right team with complementing skills and personalities: early stage investors (and business partners too, by the way) will invest in the team, not the idea. Our goal is to guide you in building a strong and well-functioning team, as well as help you uncover potential friction points or weaknesses in the team, so that you can address them in the very beginning. When it comes to the fair split with your co-founders, if you need a reference point, or just want reassurance, we have developed our own tool for equity split calculation. Hint: the one answer that’s certainly wrong is a hasty 50-50 split.

You have spotted a problem and found a viable solution – in other words, you have your idea. What’s the next step? You need to make sure that the problem your business is trying to solve is a valid problem for a wide enough group, and that

Are you sure that the problem your business is trying to solve is a valid problem for a wide enough group? 

When you spot a problem and think you have found a viable solution to create a business around, it’s all too easy to get excited and jump straight into ideating a solution.

Avoid making something and then hoping people buy it when you could research what people need and then make that.

It doesn’t make any sense to make a key and then run around looking for a lock to open.

There are many ingredients in the recipe for creating a successful startup, but most certainly whatever you read and wherever you go, one of the first pieces of advice is going to be to do your homework properly regarding the validation. You have to validate both your problem and your solution to be able to define the perfect problem-solution and later on the product-market fit. If you manipulate your future customers into liking your solution or do not reveal all the aspects and layers of a problem you identified, your idea can easily lose its ground and with that the probability of it surviving and actually being turned into a prosperous business. Let us know if we can help at this initial but yet super-important stage.

Validation is the first step in moving towards learning more about the problem you are ultimately looking to solve.

Finding your unique value proposition is only possible if you take a thorough glance at your competitors. The world of tech is highly competitive, particularly so when you operate in a field with low entry barriers, you need to carefully examine and regularly update the news and developments of those companies who act in the same field and market. This might lead to several pivots for you if necessary, because you can significantly increase your chances of success if you can offer a—at least in some aspect—unique solution to your customers. The introduction as “we are like Uber/Snapchat/WeWork/Spotify, only better” is hardly sufficient in most cases. Unless you really are so much better, but then you need to know that too, so up the competitive analysis.
