sum. allows customers to create and purchase beverages formulated for hydration and performance through a mobile app. Our technology allows customers to adjust drink size and ingredient levels, including flavor, caffeine, and electrolytes, to create a truly personalized beverage with no single-use waste.

Our science-backed ingredients are packed into 2-liter cartridges, each capable of creating 200 beverages. Cartridges are hand-delivered as needed, picked up when empty, and returned to the manufacturer for refilling.

sum. install fountains at no cost to locations while sharing a small percentage of revenue in exchange for changing out cartridges. Fountains double as ADA-compliant bottle-filling stations and are meant to replace existing drinking water stations. A 3rd party, licensed plumber performs installation and routine maintenance.

To minimize maintenance, fountains have been designed with automated self-cleaning, remote monitoring, and IoT-enabled over-the-air updates. We have four patents covering automated cleaning, inventory management and communication infrastructure, personalization of beverages using biometric data, and aesthetic design.
