The Startup That Took-Off with a Flyer

When a medical AI researcher offered Luis Wenus a video call to discuss collaboration, Luis had a different idea. "I was in San Francisco. I told him, 'I'm going to fly to New York tomorrow and we're gonna chat in person.'"

This wasn't impulsive; it was a pattern.

Years earlier, after one call with the Worldcoin team, Luis dropped out of his London university program and flew to Germany to join them. Before that? A high school student who crammed four years of exams into one year and landed at a top university.

"That's when I figured out you can just do things," he says.

This philosophy of action over deliberation shapes everything about Luis' approach to building Nolla Health, a health tech that combines AI with real doctors to deliver fast, personalized care. 



Toward the beginning of his journey, Luis needed to gain customers. While others debate marketing strategies, Luis grabbed a stack of flyers. "Free skin cancer check," they read. He stood on Norwegian street corners, handing them out one by one.

"I had no clue how we'd reach people," he admits. But instead of commissioning studies or hiring consultants, he just started. Those flyers became 40,000 patients — enough to potentially impact Norway's national cancer statistics.

The pattern repeats everywhere. Reading medical AI research papers alone could have been an academic exercise. Instead, when one paper kept appearing in citations, Luis tracked down the author and showed up at his door with working prototypes.

They're co-founders now.

"If you know you want to make something work, you just have to do everything for it," Luis explains. "It's not about being reckless, it's about recognizing that action creates information that planning never could."

Growing up with a father who was a doctor meant Luis saw healthcare's inequalities firsthand. "All the neighbors, all my friends would always ask my dad about every single thing," he recalls. That accessibility gap became his mission.

To hesitant founders crafting the perfect strategy, Luis offers different advice: "You have to really care about it. There's going to be so many times where you think it's not going to be great." The solution isn't more planning — it's conviction plus action.

Today, when users message to say the app caught something early, Luis thinks back to those Norwegian street corners. While other founders pitch to VCs in boardrooms, Luis was somewhere handing out flyers, or booking another spontaneous flight.

The biggest breakthroughs don't always begin in Silicon Valley offices. After all, 40,000 patients started with a single piece of paper and three words: "Free skin cancer check."
