a few years back i learned that glassdoor was co-founded by Rich Barton who founded both Zillow and Expedia (another interesting fact I didn't know until then: Expedia was a MS spin-off, Rich Barton built in-house at MS and then Gates and Ballmer gave the blessing to go on their own) - he's also a partner at Benchmark.<p>Never loved glassdoor but find it useful on a regular basis when hiring (esp. as one data point for comp comparisons when hiring in tech) and seems to fill a need that isn't served elsewhere (essentially yelp for HR, serving both sides), but it's not-very-sexy design made a lot more sense when I thought of it in the lineage of the majorly successful but also not-very-sexily-designed expedia/zillow. in any case, impressive for Barton to have so many successful businesses/exits and still be relatively under-the-radar compared to other comparable founders (maybe because he's based in SEA), definitely someone to follow for those who like to keep track of serial entrepreneurs.
