CoolStreamâ„¢ is the brand name owned by Exeter Science & Entertainment. They are a technology start-up based in Exeter, NH. The two owners of CoolStream, Mark and Susan, contacted ecm design to create a logo for both Exeter Science & Entertainment and CoolStream. Pleased with their results, they have since used ecm’s creative design services to brand and design packaging for their evolving CoolStream line of Bluetooth products. Exeter Science & Entertainment also takes advantage of our in-house design and print services for promotional materials.
