Ivan Kirigin discusses growing a monetized user base. He talks about his background in robotics and a failed startup. He then learned growth strategies at Facebook and Dropbox, including freemium models, referrals that provide bonuses to both referrer and referee, and automating user actions. For his new startup YesGraph, which helps companies with referral recruiting, he discusses applying similar freemium and viral growth strategies like allowing free individual use while charging for company-wide team use.
