HelloSign is another heavyweight in e-signing category. HelloSign was founded in 2010.
HelloSign and Agrello are quite similar for basic e-signing use case with key differentiator being on the collaboration aspect. Agrello allows much easier sharing of documents and document spaces with colleagues than HelloSign.
HelloSign Essentials plan ($15 USD / mo) does not offer any collaboration features and only 5 templates, while in Agrello you get Professional package for the same price with unlimited templates, and document spaces for collaboration.
If you want to use bulk creation of documents in HelloSign you need to pay minimum $50/month ($25/per person per month). In Agrello it is included in all packages.
Regarding e-signature security, Agrello provides more advanced signatures where the digital signature is created after each signing and not at the time of document download. In addition, Agrello can provide Qualified Electronic Signatures in the Baltics region.
