This week’s guest on the show is Danielle Morrill, founder of Refer.ly, a service which rewards people for sharing product referrals with others which many of us already do via social networks, word of mouth and email. Users can share links from popular affiliates like Amazon to earn cash or donate the proceeds to charity. Incubated this year at Y Combinator, Refer.ly is quickly gaining traction and support. Before starting Refer.ly, Danielle was in charge of marketing at Twilio and was a mentor at 500 Startups. SendGrid is a This Week In Techstars sponsor for this episode and proud to support innovation in the startup community. Content about the experiences in the startup world help to educate and inspire entrepreneurs all over the world. This Week In Startups highlights startups that are gaining attention and traction in the market. Jason Calacanis is the host and a well known founder of several companies including Webblogs Inc, Mahalo and most recently, the media series of This Week In.
