“In-house file infrastructure? No thank you. With Uploadcare, we save 40 hours of per week and decrease the total cost of ownership (TCO) on infrastructure development. More to ask?”

Yakov Karda
CEO & co-founder

“For us to build the functionality we use, it would probably take a team of 3 or 4 developers several months. Using Uploadcare, we've basically taken a shortcut. We haven't had to build any uploading or image-processing infrastructure ourselves, so we've saved a bunch of dev work. This part of our software is just handled. It's not something we need to worry about.”

Finbarr Taylor
CEO & co-founder

“We’ve got more than enough problems to solve in our own right, so we’re always looking for best-in-class, third-party solutions. With Uploadcare, we got what we wanted, and we didn’t have to build it.”
