About

Get to know Pobuca! 


We are SiEBEN, experts in productivity, collaboration and CRM technologies since 2000.

The idea when we started working on our startup in Feb 2015 was that business workers needed to improve the way they access their contacts - especially on mobile. We decided to conduct a market research which showed that 62% of business workers feel that they are losing more time than they should looking for contacts! Wow! It is 2016, each of us has three digital devices, and we still don’t have easy access to business contact information!

We dream to solve this problem and change the way businesses store and access their contacts globally! Since we target for a global scale, we need to have a global attitude, starting with our name; Justphonebook changes to Pobuca, a globally registered name for contact management.

February 2015 was a starting point to an exciting journey! Justphonebook introduced as a spin-off startup from SiEBEN, where our team came together and won the “Innovation Day Challenge” by contemplating this idea. Later on Justphonebook became Pobuca, the contact management app for teams.

What does Pobuca mean?

Actually it means nothing… and everything! BUsiness ContActs in your POcket = PO-BU-CA


Our dream is to change the way businesses store and access their contacts! Contacts evolve...


Our Vision is every organization worldwide to use Pobuca and realize its productivity value!
