DataXu

DataXu offers the first real-time ad optimization platform for advertisers. Unlike any other online advertising service, the DataXu platform values, bid manages and buys ads on an impression-by-impression basis, across the ad exchanges operated by Google, Yahoo and others. DataXu increases advertising ROI through automated, campaign-specific algorithms that process hundreds of thousands of “ad decisions” a second, each returned in under 100 milliseconds.

SeatGeek

SeatGeek forecasts the price of sports and concert ticket on the secondary market, analogous to what Farecast (now Bing Travel) does for airline tickets. For ticket buyers this helps determine whether to buy a ticket immediately or wait for a price drop. For sellers it helps identify the optimal time to unload their tickets. SeatGeek’s crawlers have compiled millions of ticket transactions and have also aggregated other factors that influence prices.

Healthy Wage

HealthyWage rewards health. We implement health challenges to allow corporations to reward health; we also enable employers to offer the healthywage, payments to employees for being healthy. Our first health challenge, the BMI Challenge, pays overweight Americans up to $1000 to lose weight and move from a Body Mass Index (“BMI”) of 30 to a BMI of 25.

Rackup

Rackup leverages behavioral economics to disrupt the $100B gift-card market and, more generally, the prepaid market. Fun, fast and thrilling, Rackup.com features a revolutionary gift card auction where winners always get more than they pay for. Rackup promotes customer engagement, drives traffic to retailers and increases revenue.
