“Rocketrip, a company out of the latest Y Combinator batch, wants to save companies money by paying the employee to find ways to travel on the cheap.

The idea behind Rocketrip: for every two dollars you save your company, you get paid one. If hotel rooms in the area are, say, $150 a night, and you opt to crash on a buddy’s couch instead, you just saved the company $150 bucks. You get a gift card for $75, and the company still saves $75. Find a promo code that saves you $10 off your rental car? Bam — that’s $5 bucks for you.”
