  • Map4Us (Development)

    Map4Us is an event-based location sharing solution. It keeps users updated about event members' locations right before the event and during it. Location sharing is completely temporary, immediately stops after the event finished, and positions are unreachable afterward. Inviting members is quick and simple, where you pull from your social networks and are not limited only to friends. Members can share locations between different groups of friends and enjoy events with each other.

    Fit Predictor finds a shopper's best fit in seconds using data mining techniques on data that retailers already have—without the need for physical measurements.

Fit Predictor is omnichannel, supports 1400+ brands, and over 1 million shoppers.

  • (Development)

    We've created a job placement website to help both the qualified manpower and the lower/country side manpower to find the right position. The solution solves advertising problems easily by allowing small and big companies and find the right person for the job.

  • UTix Social Ticketing (Development)

    UTix makes buying tickets with your friends as easy as possible. By forming new groups, or joining an existing one, you select exactly which friends know you are going to an event. No more confusion because UTix helps you share your seating arrangements to ensure you and your friends sit together.

  • KeywordProtector (Development)

    Selecting the best target and the proper keywords are only the first step in an AdWords campaign. During an expensive campaign, KeywordProtector helps you maintain and protect your advertising targets. Predefined rules and patterns are matched against the competitors’ advertising data and alerts are raised when immediate action is necessary to overcome the competitors.

  • Gufedo (Development)

    Gufedo is an online betting solution where users can play with virtual money only. The system has almost the same functionality like the biggest betting sites like Bwin or Sportingbet, but we added some more social and fun things.
    The concept wasn't good enough to create a viable product, but we successfully made this complex, multi-language gaming site which had more than 5,000 active players during the UEFA European Championship in 2012.
