Ben Moore

Ben Moore is Chief Product Officer at PerfectServe. In his role, Moore is responsible for product strategy, design and development, driving the PerfectServe portfolio’s long-term roadmap and shaping the company’s future as a leader in the growing clinical communication and collaboration (CC&C) space. Moore maintains an acute focus on product innovation and is known for connecting with customers directly to understand their challenges and better optimize product development.

Prior to PerfectServe, Moore served as CEO of Telmediq, a company he founded to solve the fundamental challenges, risks and financial costs associated with poor clinical communication. Upon PerfectServe’s acquisition of Telmediq to consolidate the forces behind the industry’s most comprehensive CC&C platforms, Moore joined the combined company’s leadership team and has played a vital role in the integration process.

Telmediq’s roots can be traced to a 2010 hospital stay for Moore’s wife and newborn daughter that introduced him to a strange dichotomy: physicians wrestling with pagers and playing telephone tag while their patients used state-of-the-art iPads. He saw a prime opportunity to improve the cumbersome state of healthcare communications and, ultimately, patient outcomes. Telmediq was founded soon thereafter, and Moore launched the service in early 2012.

Before Telmediq, Moore held key product, business and leadership positions for two other high-growth technology success stories—online learning platform Desire2Learn and global OSS/BSS software provider Redknee Solutions. He also has authored patents in location-based emergency messaging.

Moore holds a bachelor’s degree in Systems Engineering from the University of Waterloo, as well as a degree in Pragmatic Product Management.
