September 17, 2018 18 Min Read

Access to a large talent pool, the possibility of venture capital, and proximity to like-minded individuals makes San Francisco an attractive location for tech-startups.

Naturally, San Francisco hosts some of the world’s most beautiful workplaces. Google’s Googleplex resembles a playful, inventive campus, while Apple’s future workplace is dubbed ‘The Spaceship’.
