Authentisign has some very positive reviews from well respected Active Rain members who use the product. We have not used the product, we have been using Docusign for more than a decade, so have a grandfathered rate which would be tough to beat, but we're always on the look out for less expensive and better "anything". I spent some time on their website and found it difficult to understand "How it works" and the FAQ section seemed somewhat self serving with "Questions" being lead ins for the information they wanted to provide rather than genuine FAQs. I don't doubt that the Active Rain members who use it are genuine in their reviews - but barring those - this is not something I would pursue further.
