Joined my friend from Webjuice to pursue series of noble endeavors that we put off since graduation.

Joined my friend from Stanford to re-architect and scale Webjuice's e-marketing technology infrastructure:

● Built a high performance 24 X 7, 99.95% uptime CPA/CPC/CPM ad network/exchange that generated over US$100MM revenue for the company

● Designed and developed a social targeting engine to leverage the social graph in twitter and facebook for n-th degree social demographic-behavioral targeting

● Took over the Adteractive engineering and operation team and consolidated the PCI infrastructure

Identified a business pain from prior work experience, validated the business opportunity with numerous prospects, turned this idea into a business plan, built the prototype while continuously fine-tuning the business model, generated enough revenue to feed 2 and half employees, raised seed capital in year 2001, assembled and managed a 10 person engineering team to fuel the award-winning product, raised over US$20 million in series B and C from top tier VCs in the valley, grew the company to 40 people and attracted a high profile management team.
