Alexis has a record of identifying himself as the non-technical founder. So do many, many other founders. Just do a google on this query to see founders describing themselves as non-technical: non-technical founder site:news.ycombinator.com
From what I remember, those describe themselves as ‘the business guy’ or ‘the marketing guy’ but give advice, mainly about the attitude to have to fellow ‘non-technical co-founders’, assuming often openly that they do have a needed skill-set, that happens not to be code.
The precise word that is used to describe your role in specific situations matters a lot less than knowing what it encompasses in whole. No one is saying anywhere that you should go out of your way to tell investors that your duties include cleaning the toilet and ordering food. No, to investors you are in charge of keeping lights on; in a meeting to discuss a partnership you assume charge of user growth; when it's time for lunch you assume charge of being the pizza boy/girl.
