Discover why leading brands love Stamped

“Stamped’s full feature set encompasses both customer experience worlds: the configurability of the widgets to be in our branding, and to set our own reward levels and offerings that fit our business best. It’s really supported us in communicating our appreciation for our customers...Stamped has definitely supercharged our customer retention!”
"Stamped’s team of developers worked with our designers as if they were always part of the team...any issues that cropped up were fixed right away, and we rarely had any other ones come up. Stamped is so great that I’ve already recommended them to a few businesses that ask who I use for my rewards program. I can’t recommend them enough!”
"The team at Stamped is in another league! With other loyalty apps we’ve used in the past, we felt like just another customer on a long list. But with Stamped’s team, it’s not like that. Their team is attentive and supportive. We also found that their platform offers unique features that aren’t found anywhere else - and they come at a really competitive price."
