Marco Arment appears to have done pretty well on the Tumblr aquisition. "As for me, while I wasn’t a “founder” financially, David was generous with my employee stock options back in the day. I won’t make yacht-and-helicopter money from the acquisition, and I won’t be switching to dedicated day and night iPhones. But as long as I manage investments properly and don’t spend recklessly, Tumblr has given my family a strong safety net and given me the freedom to work on whatever I want. And that’s exactly what I plan to do." http://www.marco.org/2013/05/20/one-person-product http://www.marco.org/2013/05/20/one-person-product
