Paul is the founder of four companies and active early stage investor. He was most recently the CEO and founder of Aggregate Knowledge.
In 1990, Paul started his first venture which was an online gaming company. In these pre-internet, bulletin board days, he was one of the original innovators to bring to life the multi-player user experience. Paul’s early games from almost 20 years ago are the inspiration for several of the modern social gaming offerings.
In 1997, Paul founded Ahpah Software, a computer security firm that was the result of his work as a Ph.D. student at Princeton University. Paul’s tools for reverse engineering and obfuscation were first used by the premier security lab, the Princeton Secure Internet Programming Lab (SIP).
In 1999, Ahpah Software was split into two companies and one half was acquired by InterTrust Technologies. Paul went to InterTrust as part of the acquisition and moved into roles in business development, strategic alliances, and mergers & acquisitions. InterTrust went public and was later acquired by Sony and Phillips.
In 2003, Paul formed Tribe Network, one of the first social networks, with Mark Pincus, Chris Law, and Valerie Syme. Tribe’s lead investors were Mayfield, The Washington Post, and Knight Ridder. Tribe’s assets were acquired by Cisco and are the cornerstone of Cisco’s Entertainment Operating System (EOS). Paul is the inventor of several core patents related to social networking.
In 2005, Paul and Chris Law formed their second venture together, Aggregate Knowledge. Aggregate Knowledge was the natural product of their early work in social networking. The key insight being that the data produced by such networks would be highly valuable for predictive modeling and targeting. Aggregate Knowledge has raised over $35 million in financing from First Round Capital, Kleiner Perkins, DAG, and OVP.
Paul is a limited partner in First Round Capital and has been doing angel investing for almost a decade. He personally invested in the first rounds of Zynga, PayNearMe, and TubeMogul.
Paul holds a BS in Mathematics from Lehigh University and Masters in Computer Science from Princeton University.
