Readdle might not be a familiar name, but chances are you’ve been using some of their mobile apps. The Ukrainian company is a bootstrapped success story with 100 million downloads, 135 employees and a profitable business. That’s why I’m excited to announce that Readdle Vice President Denys Zhadanov is coming to TechCrunch Disrupt Berlin to talk about this remarkable journey.

Readdle is behind some of the most popular productivity apps on iOS, such as Spark, PDF Expert, Calendars 5, Scanner Pro and Documents. When you browse the top charts in the App Store, there’s always a Readdle app here and there.
