About

Rezku, developed by Guest Innovations and headquartered in Sacramento, California, was founded in 2012 by restaurateur and tech entrepreneur Paul Katsch to provide a powerful, easy-to-use POS and restaurant management solution for independent restaurants and local chains. Originally emerging from reservation technology, Rezku evolved into a full-featured iPad-based POS with true offline capabilities and cloud-based back office features. Its comprehensive system supports core restaurant operations including order entry, kitchen display systems (KDS), inventory tracking, CRM, gift cards, loyalty programs, online and mobile ordering, delivery dispatch, and custom branded apps—all tailored to streamline workflows and improve customer experiences for a variety of dining concepts from fine dining to quick service and pizzerias. The platform is backed by U.S.-based development and support, emphasizing reliability, real-time business insights, and tools to help independent operators compete with national brands.
