There are some similarities in our model to Bonterms. We're sort of competitive with them, in a similar way that the Apache license is competitive with the GPL.
While there are important differences in our approaches and focus areas, I'm a fan of more adoption of standards in general and there's a lot that we agree on.
Some companies choose Common Paper over Bonterms because we offer agreement types that they don't, including a Design Partner Agreement and Partnership Agreement. As far as I know, they only provide agreement templates and not software to manage them.
We as a small SaaS selling into large companies and Bonterms has made negotiating what previously took months into a few days. The customers legal team agreeing to using this format is the most complicated. We just mention that most real estate deals are negotiated on standard paperwork with an overriding cover page - and so do we. Works amazingly well.
