By providing homeowners with access to real-time water use information, Flume helps customers save water, save money and protect their home. The Flume® Smart Water System consists of an easy-to-install sensor that adapts to most existing home water meters, a bridge and an app to communicate water use to the homeowner in real-time.

Founded in December of 2013 and based in Santa Clara, California, Thalamus is the premiere, web-based, digital interviewing software specifically designed for application to graduate medical education (GME) training programs. Created by an anesthesiology residency applicant (now resident) and anesthesiology residency program director, Thalamus provides a comprehensive online interview reservation and travel experience via a real-time scheduling system – online and mobile. Whether on rounds in the hospital, studying for exams or traveling the country for interviews, residency and fellowship applicants may now instantaneously confirm their interview dates, take full control of their schedules and decrease their costs of travel. For program administrators, Thalamus streamlines communication by allowing applicants to self-schedule interviews, thereby eliminating unnecessary phone calls and emails. Thalamus handles all of the confirmations, cancellations, and rescheduling, so administrators can focus on the “personal touch” and optimize resident recruitment.
