Adgully Exclusive | CAPTCHAs with crisper and clearer advertisements: yo!CAPTCHA's Ankit Gupta

Three BITS-Pilani engineers saw a vision ' a vision to use, an unused space on the internet, which is failing to get the attention of its users, to blend it together and come up with a powerful tool?

Slambook ' which was a roaring success ' invites people to create their virtual Slambook online, and send across their Facebook friends to fill it. The app received great response, with reaching a peak of 80k monthly active users. The app right now hosts 350,000 total installed users.

"yo!CAPTCHA is a novel form of advertising. Since its inception, we have never compromised on the quality and Innovese stands tall for the fact that the product in itself speaks about its differentiation," Gupta says.

"With any new technology platform which tries to change an existing online culture, the biggest hurdle is to settle it well among the stakeholders (publishers/advertisers) mandate. By that I mean, make them understand the true potential and the reliability of the platform. Building an ad-network is difficult in its initial phases. That's what we've fired up our side, closing more and more publishers & advertisers." He adds.
