I know many people who didn't use us (or a similar co-founder agreement, except we are the only game in town if you are looking for a reputable, lawyer-approved, silicon-valley, tech-friendly one). They regretted it dearly, later. In general, first time founders are pretty clueless about IP assignment (if my co-founder dumps me, what happens to his 10,000 lines of beautiful Python), vesting (if my co-founder doesn't work out, why does he keep 50% of my company), etc... You know better than start coding without some kind of code repository. Don't start cofounding without an agreement. You've been warned :-)
