Hoolest Performance Technologies develops drug-free neurostimulation devices designed to help people break free from stress, anxiety, and panic. Founded by Nicholas Hool, Ph.D. in Biomedical Engineering, the company grew from a personal struggle with performance anxiety.
Their flagship device, VeRelief, applies patented auricular vagus nerve stimulation to activate the parasympathetic nervous system — shifting the body from fight-or-flight toward rest-and-digest in minutes, without pills or clinic visits.
Hoolest serves clinicians, high-performance professionals, and military personnel seeking drug-free relief. Their newest device, Hoolest Pro, pairs noise-canceling headphones with bilateral vagus nerve stimulation, bringing clinical-grade neurostimulation into everyday practice.

Questions clinicians ask first
Straight answers on how Hoolest devices work and who they're for.
Do you work with companies outside North America?
Yes. We run programs internationally and have active partnerships across the US, Europe, and Asia-Pacific. Our Haarlem, Cape Canaveral, Minnetonka, and Adelaide venues reflect the global reach of our community.
Can we sponsor an existing course instead of creating a new one?
Yes — this is a common "Advertise With CI" arrangement. Sponsoring a module, livestream, or course gives you aligned visibility without the lead time of building new content. Get in touch to discuss available opportunities.
How is pricing structured?
Partnerships are priced based on scope, reach, and scale. We share specifics during a discovery call once we understand what you're looking to accomplish.
Who owns the content we co-create?
IP arrangements vary by partnership. For most "Create With CI" engagements, CI retains ownership of the curriculum format and delivery infrastructure while partners retain rights over their branded content and any proprietary clinical content they bring. We detail this in every agreement.
