The storyHow they got there
Peter Hrbáčik built KWFinder in 2014 as a side project while freelancing, convinced that SEO keyword research tools were either too expensive or too ugly. He wanted something simple enough for bloggers and small businesses — not just enterprise SEOs.
The first ten customers came from Slovak and Czech SEO forums and Facebook groups, where Peter offered lifetime deals to local SEO consultants who wrote reviews. The first hundred came from a beautiful recursive move: he used the tool itself to rank their own site for "free keyword research tool" — which still drives traffic today.
At maturity, the channel mix settled into: SEO from their own tool ranking for SEO keywords (~50%), affiliate program with bloggers and YouTubers reviewing SEO tools (~25%), content marketing and YouTube tutorials (~15%), and limited paid (~10%). Heavy paid acquisition was killed early on. Affiliates and dogfooded SEO were doubled down on.
Unit economics: CAC around $50–80 mostly affiliate-driven at 30% commission, ARPU around $30/month, LTV around $400–600 at a 24-month average lifetime, and monthly churn around 4–5%. The affiliate program included a public leaderboard and ready-made review templates — turning power users into salespeople. Fully bootstrapped from Slovakia, the business reportedly crossed $1M+ MRR.
Channel MixWhere the growth actually came from
Most case studies hand-wave channels. Here's the rough allocation — not in dollars spent, but in users acquired — across the routes that actually mattered.
