we've talked about this before. we fund founders of all ages above 18 (though i think the oldest founder in the current batch is 66). we haven't calculated it yet but the median age for this batch is probably in the late 20s, with most founders in their 20s, 30s, and 40s. the last time i looked, we'd funded many more founders in their 40s than in their teens.

there are a lot of promising 16 and 17 year olds that apply that we can't fund, though i think it's probably a good thing for them that we can't.

as we have also discussed before, the majority of the most valuable companies we have funded have been started by founders in their 20s (with exceptions like stripe on the lower side and zenefits on higher side).
