2010 - After switching to a game model and doing quite well - neck and neck with Zynga. We were walked into a Facebook meeting room and told a bizarre story how Mark was upset about friend feed forms. They explained that we could only share (by means of post feed forms) our games with people that already had our games. Pleading did nothing, they ended that model. Zynaga is still flailing around.
2012 - I changed companies and focused on mobile advertising. Another decent path with 12 employees or so. We got a phone call . [EDIT REMOVED REST OF STORY]
2015 - I received another phone call from a large company (They deal in search) . I wont go into this one.
* Phone calls from large companies are extremely bad. That means they don't want things in writing.
So sure, have fun with working with large companies. Just remember one thing: they hate you.
