Dan Siroker, Co-Founder of Limitless & Optimizely

Today we catch up with Dan Siroker, co-founder of Limitless, which trains a personal AI to remember things for you. Y Combinator funded his previous company, Optimizely, in 2010, and it was acquired a decade later. But before he started Optimizely he ran the new media group within the Obama campaign, which achieved stunning results through A/B testing. In fact Optimizely was the software he wished he'd had then.
