Explore my journey.

Hi, my name is Jiri Diblik, 27-year-old founder based in Czechia and I’ve been passionate about shaping the digital world since I was 12. I love turning new ideas into reality, especially when they shake things up.

I’ve done everything from building startups and apps to mastering UX/UI, growth hacking, fundraising, and scaling businesses.

" The best time to start building your startup is now."

Over the past decade, I’ve had the privilege of working with both startups and global enterprises, including some Fortune 500 companies. Along the way, I’ve built products that millions of people use every day. I’ve also built and sold multiple startups and raised millions from VCs.

And what am I best at? Quickly shipping digital products, especially mobile apps. My background is in UX & UI, but over time I’ve also done marketing, growth hacking, and coding. So, basically, I’m a full-stack startup guy

My biggest passion lies in health tech building tools that improve lives. But above all, I love the process of creating: shipping quickly, testing constantly, and scaling fearlessly.

When I’m not working, you’ll usually find me on the court. I played competitive tennis until I was 15, then spent a few years training in kickboxing, and now I focus on padel still with a competitive mindset. In winter, I hit the slopes to snowboard. My girlfriend and I also love exploring new places together whenever we get the chance. At home, we live with Jimmy, our curious siberian kitten.

& focus on mental health apps

In 2020 I founded VOS.health and ChatMind AI, two products focused on redefining mental health through technology. Over the past year, we scaled to millions of users and pushed the boundaries of AI-powered therapy. In April 2025, both were acquired by Spring Health, one of the fastest-growing mental health companies in the U.S. I’m now part of the Spring Health team, working as a Product Manager to continue this mission at scale.

Occasionally, I step away from my own projects to help founders solve startup challenges. Whether it’s building an MVP, growth hacking, refining product–market fit, improving UI/UX, scaling, or fundraising. I aim to provide clear, thoughtful, and actionable insights to move you forward.

From time to time, I step away from building to help other founders with startup and app challenges—whether it’s shaping an MVP, finding product-market fit, improving UX, scaling, or raising funds. I focus on clear, actionable advice to move things forward.
