>But a valuable business co-founder brings extensive domain expertise, a network of people, sales skills, management skills, and fund-raising talent. I've found across industries that the technical guys typically have more domain expertise given equal time spent in that industry with way too many examples to throw in here down to entire factories being known better from just about every angle (bar the nuts and bolts) by a single senior tech guy than the actual owners and sub domain mangers. Just because he and many other technical guys in the other examples had to understand the problems in depth to develop for them and abstract them away for the managers, accountants, ppl running the machines, etc The sales skills can matter a lot especially for b2b but it's not a given that these (along other people skills) aren't possessed by the dev. I tagged along trough a ton of the studies of my girlfriend as she studied international business management... and as far as practically useful stuff goes it honestly didn't go that far beyond what we got taught in our company management course when studying compsci.(other than things like statistics with spss and the like which they seemed to almost collectively suck at.) All it gave me was a sense of wonder at the amount of buzzwords and cargoculting in that sphere outside of the usefull stuff. Don't get me wrong. There's technical guys that are bad at these 'people skills' and/or have no sense of popular aesthetics that makes their ads entirely ineffective or can't manage themselves so even your mentioned "management skills" would be usefull in a 2 people team, etc. But if a technical guy is somewhat naturally competent on these fronts... or where they're lacking they could have a technical cofounder that completes them and they both keep eachother accountable... Well then i'd put my money on them rather than a technical/mba cofounder couple.
