Best of luck. I think you need to answer two questions -- (i) how would you compete/compare against the likes of documenso.com and (ii) the usual legalities - authoritativeness, acceptance, etc.
In this highly competetive market we're currently more focused on things that we can do better like on-premises and embedding/API.
DocuSeal doesn't require any significant initial costs to be built - and then it comes only to our ability to build a great product to come over the competitors.
Regarding the compliance we're focused on simple eIDAS signatures for the EU and also we follow the UETA and the ESIGN Act.
We're using Ruby on Rails and Vue to build DocuSeal and it really helps us to stay lean and ship features fast while being bootstrapped.
Here is a short list of what the tool can do:
- Automatic eSignatures
- Multiple submitters
- 10 document form field types
- Emails via SMTP
- AWS S3, GCP, Azure Cloud files storage
- Open large files up to 500MB
I'm happy to answer any questions!
