At 14, David began exploring telecom technology with his home telephone and hi-fi radio.

As the internet grew in significance, he was determined to bridge traditional telephone technology with the new network. He founded Deltapath in 2001 and developed the first-generation SIP based telephone system. The software lets business communication systems work over the internet, simplifying set up and reducing costs for businesses.
