ADVICE

Make 100 Reels Fast To Learn What Works

Post lots of short-form content quickly to break the mental barrier: Vadim committed to 100 reels and posted daily for three months to learn hooks and formats.
Use proven playbooks (he followed Brendan Kane's workbook) and boost top-performing reels with small budgets.

INSIGHT

Treat App Growth As A Funnel Of Five Steps

Focus sequentially on the funnel: impressions, downloads, sign-ups, conversions, retention; later steps don't matter if earlier ones are broken.
Vadim learned to stop overbuilding features and instead test onboarding, pricing, and paywalls first.

ADVICE

Run Relentless Onboarding And Paywall Tests

Test many onboarding and paywall variants aggressively: Vadim ran ~30 paywalls and multiple auth flows to find what converted.
Small changes (order of auth, trial placement, coupon) materially changed trial-to-paid conversion toward ~15%.

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.
