If the pitch is that it would save money on legal fees, then that could be a big value add. But if that's the angle, then my last question, regarding whether the docs are meant to be closed-universe and vetted, or open-universe and not vetted becomes critical. Founders wouldn't want to be changing options around and not realizing that they are creating confusing or unexpected results.
If they're supposed to still use a lawyer, then that blunts the value add (and the lawyer would likely resist the standardized agreement because it means fewer billable hours). But maybe you can get enough critical mass to be an 800-lb gorilla, like the SAFE has become? I appreciate the quick responses here, and am taking a look at the agreements to see if they could be relevant for our business.
