The accidental €25K spike from a billing bug

Most founders quit after their first failed product. Vadim failed three apps before finally building one that worked.

Vadim is the founder of KBMH, a kettlebell workouts app that grew from a simple MVP built for himself into a fast-growing fitness app generating $80K+ per month.

After years of failed ideas, bad product decisions, and zero traction, everything changed when Vadim focused on validating ideas faster, testing onboarding and monetization aggressively, and building a personal brand that now reaches 400K+ followers on social media.

In this episode, Vadim shares the real story behind the growth of KBMH, from launching fast with landing pages to running nonstop monetization experiments and even how a mistake in his cancellation flow generated a $40K revenue spike.

If you're building an app, validating a new idea, or trying to scale revenue, this conversation is packed with real lessons from the trenches.

You will discover:

✅ The landing page strategy he uses to validate app ideas before building

✅ Onboarding and monetization experiments that drove 15% trial-to-paid conversion

✅ The accidental $40K revenue spike caused by a cancellation flow mistake

✅ Why simple ad creatives outperform polished ads
