StayFi helps operators like those on Airbnb and Vrbo market directly to guests through customized WiFi splash pages.

OrgPad is a digital whiteboard tool used by over 17,000 people worldwide. It was co-founded by Vít Kalisz, who, along with a small team, created the web-based tool to help with studies, decision-making, and complex problem-solving. With no employees and a modest revenue of around $1,000 a month, the team has grown the platform organically by building a strong community without spending on advertising. Their commitment to ease of use, universality, and community-building has been crucial to their success.
