Behind revolutionary tech start up Geegleee is a founder with a singular vision: to empower everyone, from engineers to everyday users, to make better, smarter and faster decisions. Here we speak to trailblazing founder Vincent Holley about Geeglee’s journey so far.
With innovation accelerating at breakneck speed, one startup is quietly reshaping the way industries approach problem-solving. Geeglee—described by some as “the Google of engineering”— is a new breed of software that allows users to simulate, model, and test ideas in a matter of minutes, without the steep learning curves of traditional tools.
A simple idea with extraordinary potential
At its core, Geeglee is about making complex decision-making accessible to everyone. “It’s not more complicated than using an Excel file,” Vincent Holley explains. “But instead of just crunching numbers, Geeglee understands natural language. The result is a system that combines mathematical logic and everyday language to build models of real-world systems—whether you’re designing a nuclear reactor or just buying a new bike.”
From PHD to prototype
The journey to launching Geeglee has been one of perseverance and belief in a different way of thinking. After completing a PhD, Holley spent five years working with leaders in the global industry. “I created a prototype and spent two years working with major players. Eventually, we made the software simple enough to be used by anyone—not just experts.”
In a bold move, he funded the company himself. “I sold my flat and didn’t raise money,” he shares. “I’m not following the flow. If people say something is impossible, I say, ‘Then it’s for me.’”
This philosophy of independent, contrarian thinking is at the heart of Geeglee’s success.
Built for experts, made for everyone
While the platform is already being used by major clients—including top automotive and engineering firms—the aim is not exclusivity. “It’s for experts, yes. But also for anyone who wants to take decisions. If you want to design a new bike for your son using different parts, you can use Geeglee to find the best solution.”
The interface is split into two parts. First, users define their logic in a familiar spreadsheet-like layout. Then, at the click of a button, Geeglee turns that model into an interactive application. “You can ask for the cheapest solution, the lightest, or the most efficient. It’s like business intelligence—but in real time and driven by your own thinking.”
Changing how decisions are made forever
So what exactly is the value Geeglee brings? For one, it saves time. “Even at the early prototype phase, some clients say they save 30% of their time,” the founder notes. “And when you’re dealing with millions of design configurations, like at Mercedes-Benz, it reduces huge risks. Without tools like this, those scenarios would never be studied.”
More importantly, Geeglee allows for decision-making based on deep exploration rather than gut feeling. “Today, most decisions are taken because it’s time to take them—not because we’ve studied all the possibilities. Geeglee changes that. It lets you model, test, and compare scenarios in ways that were never possible before.”
A global mission, rooted in collaboration
Currently, the company operates with a small team of 10, based in France. But its reach is far broader. “Seventy-five percent of our team members are from outside France,” Holley says. “We’re building a worldwide company that values cultural diversity. Everywhere we start a business, we want to build teams with local people.”
And it’s not just about building software, but reshaping cultures. “We want to put expertise back on the table. In a world obsessed with artificial intelligence, we risk forgetting the knowledge we’ve built over centuries. Geeglee is here to remind us that human expertise still matters—and it’s even more powerful when amplified by the right tools.”
A word of advice for other innovators
As someone who’s taken the road less travelled, Vincent Holley has one key piece of advice for CEOs and innovators diving into the world of AI: “Don’t follow the flow. Only dead fish follow the flow.”
He elaborates: “AI is a powerful tool, but if you’re just doing what everyone else is doing, you won’t stand out. You have to keep your mind open. Put some people in the boat, but also send others out in new directions. That’s where real innovation comes from.”
He’s quick to acknowledge AI’s power—but also its limitations. “AI learns from databases. If you want to build the next generation of aircraft, it can’t help you. But your people—your experts—can. Geeglee just gives them the tools to explore everything they can imagine.”
Looking ahead
2025 is shaping up to be a landmark year for Geeglee. Following the successful use of its technology on a major project in France, the team is focused on expanding access to the platform and continuing to support its growing customer base around the world.
“We’re travelling a lot, helping companies change the way they work. But the biggest news is that we’re opening up Geeglee for free. We believe in giving people the tools they need to create a better world. We already have enough support contracts with big clients to sustain the business, so we want to open it up to everyone.”
It’s a refreshing approach in an era where AI tools often come with high price tags or steep subscription models. Geeglee is flipping that narrative.
“Our main objective is to replace Excel for the whole industry,” he says. “In 10 or 20 years, I believe everyone who uses Excel will use Geeglee instead.” It’s a bold ambition—but if the past few years are anything to go by, Geeglee is just getting started.
