The time to build is now! Hi — I'm Jiri Diblik. Guiding Startups to Success. Explore My Journey Within.

Hi, my name is Jiri Diblik, I’m from Czechia, right in the heart of Europe, 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, with a special focus on mobile and web apps.

Outside of work, I enjoy life’s adventures and split my time between Prague and San Francisco.

" The best time to start building your startup is now—tomorrow is too late."

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 and UI, but over time I’ve also done marketing, growth hacking, and coding. So, basically, I’m a full-stack startup guy

& focus on building 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. I’m now a Product Manager at a stealth company, continuing to build the future of mental wellness.

Occasionally, I step away from my company to consult on startup or app challenges. Whether it’s building an MVP, refining product-market fit, enhancing UI/UX design, scaling, or fundraising, my goal is to provide thoughtful, actionable insights to drive your success.

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.
