I am part of an entrepreneurship group at Stanford organizing an event called eHorizons. We take a group of 20 or so Stanford students interested in startups around to a handful of early-to-mid stage companies. I'm looking for interested technology companies. It's a great way to connect with the Stanford entrepreneurship community.
It's not a big commitment. The visit usually lasts 1-2 hours. The company typically gives the students a brief tour of their office, a description of what the company does and its history, and then there's some discussion/Q&A. If you're involved in a company that might be interested, you can contact me at mgummelt at stanford dot edu. Thanks!
