TechCrunch: Box Acquires eSignature Vendor“I think what is interesting here is that Box is going to integrate SignRequest and bundle it as part of the standard service. That’s what really caught my eye as the challenge with e-sig is that it’s typically a separate product and so gets limited use. They bought it partly in response to Dropbox, but it was a hole that needed fixing regardless so would have done so anyway,” Pelz-Sharpe explained.
