Could be a little more sneaky though, i.e. give a little box in the end to "explain" answering yes or instead of 1 yes/no drop down, make 1 drop down for each choice. Also couldn't hurt to throw some irrelevant yes/no questions to hide the questions that matter, something like "Do you own pets?" or "Do you use dialup?"

As it is now, if you have a clue you can probably figure out that answering yes is pretty much an instant disqualification, since the system will never know if you are answering yes to only 1 founder(probably seems like no big deal to most people) or yes to none of the founders are programmers.
