With a legacy spanning over four decades, we’ve dedicated ourselves to pioneering cutting-edge technology, tailored to empower car retailers and manufacturers in achieving their objectives. Our remarkable journey commenced in the quaint town of Hungerford, UK, where we established our roots under the name Kerridge. Over the years, our unwavering commitment to excellence has seen us undergo various transformations through acquisitions and exponential growth. Renowned as ADP Dealer Services and CDK Global during our expansion across the UK, Europe, the Middle East, Africa, and Asia, we proudly welcomed a significant milestone in 2021 when we were acquired by Francisco Partners, a preeminent technology investment firm. Embracing this new era, we emerged as Keyloop.

Kickstarter

Kickstarter campaigns make ideas into reality. It’s where creators share new visions for creative work with the communities that will come together to fund them. Some of these creators, like Critical Role, TLC, and The Smithsonian Institution already had huge fanbases. But many projects have been as small-scale as a limited run of silent meditation vinyls or as up-and-coming as early versions of Issa Rae's Insecure and Phoebe Waller-Bridge’s Fleabag. No matter what, creators always control how the work comes together—no 100-page grant applications, no donors demanding you modify your message, no last-minute edits from investors. When backers chip in funding and help spread the word, they too become part of these independent works.
