Clustered around South Park in Soma are hundreds of companies in the forefront of the city's latest tech boom, occupying blocks where disruptive innovation has been a way of life for decades.
Just a few doors down from the old 70s Rolling Stone office on Third Street, for example — and across the street from where HotWired aka Wired Digital operated in the 90s — sits the Founders Den, a shared office space and private club for serial entrepreneurs.
Co-founder Jason Johnson, at 40 himself a serial entrepreneur with four startups in his past, had left his job at Dolby Labs in spring 2010 and was working out of his home on Potrero Hill, when he realized he missed the comraderie of hanging out with his former colleagues and geeks. So he sent out an email inquiring to a bunch of them whether anyone would like to share some office space with him downtown.
The response was positive and immediate, and three of them became his co-partners in launching Founders Den this past January. The well-designed space does not serve as an incubator, or a mentoring lab, but as a co-working environment for those companies with seed funding but not yet ready to get their Series A round of funding.
