Jonathan Geller
Chief Executive Officer
Jonathan has been disassembling and wiring back electronics since he was five years old. His life is full of genius founder stories: hack into high school computer network, start computer company in high school, drop out of college to start a business. He's founded three companies since, including Telair in 2005. SIPSTACK is how he's going to revolutionize VoIP.
Stam Loizides
Chief Innovation Officer
Stam is the secret ingredient that ties the team together. It's rumoured that he has an MBA, and that he's lived and worked in ten different
countries. No one really knows what he does (including himself). What we do know is that he can tackle every problem from infinite perspectives, which
makes everything tremendously better.
Errol Geller
Chief Financial Officer
Errol loves taking on challenges and is very good at math. He has several decades of experience as a Senior Risk Management Executive at IBM. Errol is instrumental in getting SIPSTACK to where it is today.

Her biggest professional challenge thus far has been to keep this bio short. She has clearly succeeded.
