Who We Are

Information about the makers of Chord

Jared Marmen View Jared Marmen's profile on LinkedIn

Jared first began drawing up plans for Chord as a graduate engineering student in 2006 and never completely put it down. As an engineer, project manager, and entrepreneur, he has a proven ability to develop and bring to market innovative products and approaches. Jared led the development of innovative technology products, growing an $70k federal grant into a technology product line that generated a 24x return on investment. He has personally worked with every piece of technology used in Chord and the suite of planned Barttron products. Jared has a BS in physics from St. Mary’s College of MD, which is where he fell in love with his roommate's yellow lab Homer and later adopted Homer’s nephew Bart, our company’s namesake. Jared has a MS in Electrical and Computer Engineering from Johns Hopkins and a new yellow lab named Nelson, a proud Chord test dog.


Dr. Nina Cracknell

Dr. Nina Cracknell is our animal behaviorist. She has a PhD in Canine Behavior and Welfare from University of Lincoln (UK). Her research interests lie in understanding the causes of animal behavior in order to aid the development of optimized animal training methods. Nina is passionate about applying learning science and reward based training techniques to facilitate the learning process, and bond, between animals and their caregivers. She believes that, as animals are always learning, teaching should be able to happen wherever they are.


Brandon Jennings

Brandon is a recent graduate from Stanford University with a Master’s in Mechanical Engineering and a concentration in mechatronic systems and controls. In addition to his impressive academic background, Brandon has five years of experience developing and testing mechanical and electronic aircraft systems. His knowledge and expertise are deep and wide including traditional controls, modern automatic controls, machine learning, autonomous system development, mechatronic system development, and embedded system development. In addition, he has experience with simulator systems including military aircraft and BMW’s Munich-based dynamic simulator. Brandon leads the development of the Chord collar and is the driving force behind the innovative electro-mechanical design.


Amy Lauer

Amy is an innovative and driven accounting professional with over 20 years of experience. She has a BS in Accounting from Villanova University and is a CPA. Amy has two lovable, large pups - a chocolate lab named Brutus and a greater swiss mountain dog named Heidi. Both of her pups are rescues so Amy looks forward to using a Chord collar to refine their behavior, most of all to keep her naughty Brutus out of the trash.


Josh Merchlinski

Josh is an animal lover and management expert with deep skills in strategy, digital transformation, mobility, and innovation management. He loves challenging the status quo and and blazing new trails both figuratively and literally -- particularly with his gigantic Newfoundland named Kuma by his side.
