I'm a startup guy & full stack hacker, turned CEO. Current focus is Buffer, a new way to share great content across social networks. I took the concept from idea to revenue in 7 weeks of evenings and weekends from my bedroom. Now we're a team of 18 and we have 1.2M users sharing over 2M social posts per week. I also love to advise others and share my experience where it can help. I blog at http://joel.is and regularly meet with startup founders to help with challenges. Key areas of interest: bootstrapping, validating an idea, lean startup, customer development, metrics, getting traction, press, co-founders, accelerators/incubators, raising investment, hiring, personal development, productivity, culture, transparency.
