Mangools

Peter Hrbáčik launched KWFinder in 2014 as a solo side project — a keyword research tool that was simply easier to use than the incumbents. He was a developer frustrated by the clunky UIs of existing SEO tools and built something he'd actually want to use himself. KWFinder went viral in the SEO community almost immediately. He added more tools — SERPChecker, SERPWatcher, LinkMiner, SiteProfiler — and rebranded the suite as Mangools in 2016. Growth came entirely through content marketing and SEO: detailed comparison articles, tutorials, and a generous free trial. By 2018 the company was generating $220k/month with a small team based in Bratislava, Slovakia. Mangools crossed $2.5M ARR and served over 1.1 million users and 25,000 paying customers worldwide. No venture funding, no ad spend — just relentless focus on making SEO tools that professionals actually enjoyed using. It remains one of the best examples of a niche SaaS tool defeating category leaders through UX and price positioning.
