I completely agree with this. I've only known my cofounders for ~five months (we formed during the previous local startup weekend; never met before that) but it sure feels like we've known each other a lot longer. People have even been telling us that from watching us interact, if they hadn't known different, they'd have assumed we'd known each other for many years. This really makes a huge difference. It makes working together easy. Interestingly enough, I'm the technical cofounder and they're the non-technical (using the usual definition, not the one in the article) cofounders, but they bring a lot of value to the table. Between them, they bring a massive network (both in the industry and in the startup scene in general), many years of experience in their areas and a track record. I've also (obviously) seen them work and its impressive. Before I teamed up with them, I was squarely in the only-technical-founders camp, but now I couldn't imagine starting a company without them.
