Before he started building his first fire safety company called Klika BP in the 1990s, he worked as a safety technician at the district institute of national health. Klika BP still exists on the market, but apart from the name itself, František Klika no longer has anything to do with it. In 2009, he founded FIRESI s.r.o. and decided to start over and invent new and innovative products in the field of fire protection. And it worked. Today, for example, it is the only Czech manufacturer of extinguishing systems for rack-level data center fire protection.
