An interesting idea. In my experience it’s investors, not founders, who are often the source of complexity in startup agreements. I’ve found that angel investors or investors without a huge amount of experience with common practice in the YC/SV world struggle with concepts like SAFEs and convertible notes — even if they’re otherwise sophisticated investors. And those types of investors are often the only ones ready to bet money on very early stage startups.
All that’s to say: don’t neglect the educational aspect of what you’re selling. Make it easy for founders to explain how your documents works, and make it easy for investors to trust the documents you’ve prepared.
