Our Team
Meet the entrepreneurs behind Legacies Management.
Meet the Founders
We're not your typical investors. We're engineers, entrepreneurs, and fathers who understand what it means to build something from the ground up.
Between us, we've written thousands of lines of code, scaled businesses, raised families, and learned that the best companies are built on trust, technical excellence, and genuine human connections. We don't just write checks—we roll up our sleeves and get to work alongside your team.
Dennis Röhner
Co-Founder & Managing Partner • Father of 2
I'm a software engineer turned entrepreneur who's spent the last decade building and scaling a tech company. As a father of two, I understand the weight of a legacy—both the one you leave for your children and the one you've built in your business.
My coding journey started with R back in university, but I quickly moved on to Python for its elegance and JavaScript for its versatility.
These days, I'm fluent in Python, JavaScript/TypeScript, Delphi, and SQL, leveraging new programming paradigms like LLM-supported coding and agentic coding as well. Over the years, I've found that it matters less which programming language you use and more that you understand the problem you are trying to solve.
My Operational Strengths:
"I believe the best technology decisions are the ones that serve customers best. Not all software needs to be fancy-looking and complex. It's about solving problems in the most efficient way."
When I'm Not Coding:
You'll find me at the opera, on the tennis court, or playing board games with the kids — all activities that teach patience and attention to detail, qualities that serve me well in business.
Thibault Mercier
Co-Founder & Financial Partner • Father of 1
I'm a Risk & Safety engineer with a passion for learning and automation. With time, I drifted towards the financial world, using my technical knowledge to find great companies, especially in the software world.
My coding adventure began with C and C++, as well as assembly in engineering school (ah, the joys of manual memory management!).
Today, I mainly used Agentic tools to help me code in various languages like Python, JavaScript, and SQL. My real strength lies in cross-communication between technical and business teams, and translating concepts into business and financial strategies that actually work.
My Operational Strengths:
"I believe every great business decision starts with understanding the numbers, but it's completed by understanding the people. When I analyze a company, I'm looking for the story behind the metrics—what drives the team, what excites the customers, and what makes the business truly defensible."
Beyond the Spreadsheets:
When I'm not learning something new or discussing investments, you'll find me running in Munich or playing intellectual games. The former to give me the time to think, and the latter to develop my strategic skills.

Industry Network
We want to build relationships with key players across the software ecosystem—from enterprise customers and distribution partners to specialized service providers and talent acquisition experts.
Whether you need introductions to potential enterprise clients, partnerships with complementary software companies, or access to specialized development talent, we want this network to open doors that might otherwise remain closed for our subsidiaries.

How our combined skills fulfill Legacies Management's mission.
Our complementary expertise in engineering, finance, and technology leadership allows us to address the full spectrum of challenges and opportunities facing software companies today. Together, we provide a unique blend of operational support, strategic guidance, and technical innovation that ensures the companies we acquire not only continue to thrive but reach new heights.
