Listen up about Alex Louisy

Check it out, we’re talking about Alex Louisy, this guy’s a total boss. He jumped into the startup scene with a clear mission: fix that messy cash flow problem in B2B. Co-founded Upflow back in 2018, and man, he’s been crushing it ever since.

Before all this, Alex was deep in the finance and telecom world, investment banking, then managing international growth at Wifirst. Dude’s no stranger to high-stakes environments. But what really lit his fire was seeing how many businesses struggle with late payments, often needing loans just to stay afloat. That problem? It’s what made him jump into fintech and build Upflow, a software that helps companies get paid faster, improve cash flow, and make life easier for everyone involved.

Now, here’s where it gets wild. In 2020, the company was almost dead, only four months of runway left. But Alex didn’t freak out. Instead, he made some serious gutsy moves. Cut 30% of the team, hustled through 300 investor calls, and managed to secure €1M ARR and hit profitability in just a year. That’s some real resilience right there. It shows he’s not about giving up, he’s about finding solutions, no matter how tough the grind.
