I am one of the testimonials on the site, and I can verify that DocuPull has done exactly what it says.
I used it mostly to get a filled Loan Application so that I could send it to other lenders and have them flll out a new application instead of me spending an hour to do it.
I used DocuPull to get my pre-approval. I received a response in a few minutes. Also, I want to highlight the super convenient process to submit all the documents. It was not confusing at all. It took me all of 3-4 minutes to submit my documents and provide my information. Following this, I received a response in a few minutes. Loved the experience. Highly recommend!!
