Yesterday, we broke news about 500 Startups planting a flag in S.F. Will more Silicon Valley firms do the same? Custom Spaces founder Jenny Haeg certainly sees more and more VC firms opening offices in S.F. Look at Google Ventures, Kleiner Perkins, Matrix Partners, and Shasta Ventures. She thinks the trend is due to the gravitational pull of success stories. As the talent pool center of gravity shifted north, the city became more and more appealing. Companies like Twitter, Dropbox, Airbnb, Pinterest, Yammer, and Instagram are all based in the city and contribute to that effect.

Total investment dollars in software, media and entertainment, and consumer products and services was equal to over half of all investment dollars in Q4, according to NVCA. (The other half are really attached to their typewriters.) Last year, Jenny helped Index Ventures find a 3,600 SF pad across from AT&T Park at 139 Townsend, which features open desks and an entrepreneurial vibe.
