OnePIN Inc, a stage 1 ventures portfolio company, has deployed its mobile contact sharing and social networking platform with more than 65 service operators and 16 million users.

The benefit of this non traditional approach: OnePIN is able to approach sales through SIM card manufacturers, rather than direct to consumers, carriers or even handset manufacturers.
