On the flipside of LAC’s, there’s also the go out and do it yourself route. Babson is a great school for entrepreneurship that has a partnership with Olin that could offer an interesting mix of business and tech. Northeastern offers co-op’s and good business/STEM which makes it easy to go co-op in the Valley. Most I know go for tech but people also go for business, and there’s probably a good way to combine that for those interested, though I know the tech world more than the business world (Disclaimer: I’m a Northeastern student). Lehigh is another school offering interesting business/tech combinations.
I think the crux of this is that the tech entrepreneurship route doesn’t really have pipelines and even today is still a bit of a wild west. Proximity or availability to go there may be important in the search. Both Babson and Northeastern offer great ways to spend time in SV while being a student as well.
