"It took less than a day to integrate Notarize into our existing lien waiver + payment workflow, opening up our platform to a huge new customer base. I can't say enough about the product and team."
Geoff Arnold
"Notarize has quickly become an important part of our loan workflow. Every loan we grant requires a notarized document, and Notarize has been able to grow along side of our business. They expertly handle our increasing monthly volume with their 24/7 service (which our clients love!)"
