Already posting on LinkedIn but feel like your content could be doing more for you?
These Hungarian CEOs have built strong personal brands on the platform.
They share insights, tell stories, and connect with their audiences in ways that build trust and open doors. Not just for their companies, but for themselves as leaders.
If you want to see how top voices in Hungary are making LinkedIn work for them, and get ideas to step up your own presence, this list is where to start.
Peter Balogh – CEO, STRT Holding Nyrt.
If you’ve ever tried to build something from scratch, you know how tough it gets.
Now imagine doing that, scaling it to 800+ people, and still having enough energy left to guide the next generation. That’s Peter Balogh for you.
Before STRT Holding, Peter co-founded NNG, a navigation tech company that became one of Hungary’s most successful startups.
After stepping down, most people would’ve taken a long break. Instead, Peter built STRT to back founders who are just getting started, because he knows how lonely that road can be.
Who Should Follow Peter Balogh?
- First-time founders wondering “what’s next”
- Startup dreamers who need clarity and courage
- People who want real talk about building companies
About STRT Holding Nyrt.
STRT Holding is where early-stage startups in Hungary come to grow up.
It’s not just about money. STRT trains founders on product, AI, and fundraising with actual, practical guidance.
They’ve already backed over 100 companies and launched a full-scale educational platform.
Not bad for a firm that still feels more like a startup itself.
LinkedIn Content Strategy
Peter doesn’t post every week, but when he does, people listen.
He tells stories about founders, about challenges, about cherry trees (seriously).
One post might break down why startup experience gaps are a real issue in Eastern Europe.
Another might reflect on what it means to be a good mentor.
No fluff. Just honest insights that feel like they’re written by someone who’s been through it all and came out stronger.
How He Uses LinkedIn as a Branding Tool
- Tells personal stories that stick
- Highlights real founder journeys, not just wins
- Shows up as an educator, not just an investor
What Makes Peter Balogh Different
Peter doesn’t pretend to have all the answers.
He talks about mistakes, missed opportunities, and how he had to learn things the hard way.
That kind of vulnerability hits home, especially for people trying to figure it out themselves.
He also knows how to make you feel like you're in the room with him, hearing the advice firsthand.
Key Takeaways for Your LinkedIn Strategy
- Tell stories you’ve lived, not just stats
- Teach something useful, even in short posts
- Show up for your audience, not just for your brand
Where Peter Balogh Can Grow (on LinkedIn)
Peter could bring in more visuals.
Quick behind-the-scenes videos or slides from his trainings would help more people “see” what he’s building and make it easier for his audience to share what they’ve learned from him.
Istvan Simon – Founder, CEO, Prefixbox AI
Some people build products. Others build bridges.
Istvan Simon does both.
After years at Microsoft Bing in Paris and London, Istvan could’ve stayed in the big leagues.
But instead, he came back to Hungary with a bigger mission: helping e-commerce stores serve their customers better.
That’s how Prefixbox AI was born, a company that turns clunky on-site search into something smooth, smart, and actually helpful.
And now? His platform is quietly powering millions of searches without most users even realizing it.
That’s the sweet spot. High impact, low friction.
Who Should Follow Istvan Simon?
- Founders building SaaS products that need to work fast
- Product managers juggling customer experience and backend performance
- Anyone fascinated by how AI shows up in your everyday shopping
About Prefixbox AI
Prefixbox AI is built for modern online stores.
They help businesses improve how people search, find, and buy products, whether it’s through autocomplete, natural language queries, or AI-powered assistants.
Their AI Agent is already live in stores and handles serious traffic, including API requests at scale.
It's not theory. It’s running in the wild.
LinkedIn Content Strategy
Istvan isn’t trying to post every day, and that’s part of the charm.
When he shares something, it’s usually big: a product launch, a Shopify integration, a peek into what Prefixbox is solving next.
His posts are clear, structured, and usually come with a quiet sense of momentum.
No bragging. Just progress.
He also gives you just enough technical context to know what’s going on without making you feel lost.
That balance is hard to pull off.
How He Uses LinkedIn as a Branding Tool
- Shares milestones with calm confidence
- Uses numbers and features to back up his claims
- Positions Prefixbox as quietly dominant in e-commerce AI
What Makes Istvan Simon Different
He doesn’t rely on buzzwords to get your attention.
Instead, he lets the product speak.
His updates feel like a founder explaining what’s going right, what they’ve learned, and why it matters for anyone building in AI.
You can tell he’s been on the engineering side and the leadership side, and he’s not picking one over the other.
Key Takeaways for Your LinkedIn Strategy
- Talk about your product in real-world terms
- Don’t post to post—post when you’ve got something worth saying
- Keep your audience curious, not overwhelmed
Where Istvan Simon Can Grow (on LinkedIn)
He could go deeper on the human side, customer wins, team stories, or what keeps him up at night when scaling AI.
That emotional layer would make an already strong presence even more magnetic.
Albert Sárospataki – CEO, Billingo
Albert Sárospataki knows what it feels like to almost lose it all.
There was a moment, right before a key launch, when Billingo nearly ran out of cash.
Most CEOs would’ve panicked. Albert kept building.
And when Hungary rolled out new tax rules, Billingo wasn’t just ready, they became the go-to platform, helping thousands of businesses stay compliant.
That kind of resilience? You don’t fake it. You earn it.
Who Should Follow Albert Sárospataki?
- SaaS founders trying to navigate chaos and uncertainty
- Freelancers and entrepreneurs managing their own finances
- Leaders who appreciate real talk over polished highlights
About Billingo
Billingo is Hungary’s leading invoicing and business admin platform.
It helps businesses send invoices, calculate taxes, track performance, and stay legally compliant, all with a clean, easy-to-use interface.
During a recent tax policy change, Billingo processed 85,000 invoices in 10 days.
They didn’t just adapt. They crushed it.
LinkedIn Content Strategy
Albert uses LinkedIn like a journal you actually want to read.
He writes about burnout. About second-guessing his own decisions.
About running a company when you’re not sure how the next month will play out.
Then he shows how he and the team got through it.
His posts are full of raw insight.
No fluff. No ego. Just the stuff founders are really thinking about but rarely say out loud.
How He Uses LinkedIn as a Branding Tool
- Shows the human behind the CEO title
- Turns mistakes into lessons people can learn from
- Shares company updates in a way that feels like a conversation
What Makes Albert Sárospataki Different
He’s one of the few SaaS CEOs who talks openly about stress, self-doubt, and tough choices.
That vulnerability makes his wins feel earned and his advice feel grounded in reality.
You get the sense he’s building for the long haul, not the headlines.
Key Takeaways for Your LinkedIn Strategy
- Share what’s hard, not just what’s working
- Speak to your audience like they’re teammates, not followers
- Let your story teach, not preach
Where Albert Sárospataki Can Grow (on LinkedIn)
He could level up with short videos or team features.
Imagine a 60-second peek behind the scenes at Billingo or a customer story that shows how the product saves the day.
That emotional touch would hit home with even more people.
István Joó – CEO, Hungarian Investment Promotion Agency (HIPA)
When you scroll through István Joó’s LinkedIn, one thing jumps out: this isn’t just a guy running numbers. He’s out there telling a story, one that puts Hungary on the global investment map.
He’s walked the halls of government, negotiated trade deals, and now leads HIPA, the agency responsible for attracting big-name investors to Hungary. But his updates aren’t the stiff kind you’d expect from a government CEO. They’re real and focused.
They show how investment creates jobs, sparks innovation, and builds the kind of momentum you can feel. In one post, he celebrates Hungary climbing the Kearney FDI Confidence Index, from 22nd to 17th.
That’s not a vanity metric. It’s a signal to investors that Hungary is open for business and playing to win.
Who Should Follow István Joó?
- You work in business, trade, or policy and want a front-row seat to how economic growth actually happens
- You lead an R&D or service center in Europe and want to see where the action’s headed

The more we can see and hear the energy, the more magnetic the message becomes.
Gergo Gyebnar – CEO At Black Cell International
Gergo Gyebnar talks cybersecurity. But not in the way that makes your eyes glaze over.
One post might dive into MITRE frameworks. The next? A reflection on ancient philosophies and how they shaped his leadership style. Somehow, it works.
And it’s exactly why scrolling through his feed feels like flipping between chapters in a strategy playbook and a personal journal.
He leads Black Cell International, a cybersecurity firm that helps businesses lock down both IT and operational tech. Think: critical systems, the ones you can’t afford to let fail.
But on LinkedIn, Gergo isn’t just pitching services. He’s teaching, thinking out loud, questioning, and sharing. His posts read like conversations with someone who’s walked the fire and took notes along the way.

🔗 Visit Black Cell International
What’s His LinkedIn Strategy?
Gergo flips the script. Instead of polished corporate blurbs, he shares raw reflections. One post breaks down a technical audit.
The next walks you through what reading the Koran, Bhagavad Gita, and Buddhist sutras taught him about empathy and systems thinking. It’s a mix of sharp and soulful, and it grabs attention.
How He Uses LinkedIn As A Branding Tool
- Offers technical breakdowns in a clear, helpful format
- Shares his personal leadership journey through spiritual and philosophical readings
- Positions Black Cell as a learning-first cybersecurity firm
What Makes Gergo Different?
He’s not afraid to zoom out. Way out. He connects ancient teachings to modern threats. He questions his own thinking and brings curiosity into a space often ruled by jargon.
He leads with vulnerability you don’t often see in cyber.
Key Takeaways for Your LinkedIn Strategy
- Don’t just teach, reflect
- Use contrast: one post technical, the next personal
- Let your thought process show, not just your outcomes
Where He Can Grow
More visuals would take things up a notch. Imagine diagrams of those frameworks he talks about or snapshots from a talk he gave.
Short videos walking through real-world scenarios could turn his knowledge into even more of a magnet.
