> $920k over four years
so this gives an average yearly salary of 230k. Very close to FAANG senior salary with much more risk, effort and (probably) worse life-work balance. OP quit from google in 2018 and ran some other business, and this is his biggest sale so far. I think it shows how hard it is to make better money outside FAANG even when extremely talented and lucky like OP. But it's probably more about lifestyle choices.
