“A device does not matter unless it makes it all the way through development, regulatory, and into real clinical use.”
Bio
Hal Walbrink is a Venture Partner at Suncoast Ventures, where he leads device, regulatory, and intellectual-property diligence across the medtech portfolio. He brings the engineer-mentor's lens to early-stage hardware investments — practical, specific, and grounded in four decades of building products that actually reach the operating room.
Hal is the Founder and CEO of Xinetix Medical Product Development, which over its 31-year history has served 100+ medical device companies, generating combined annual product sales of more than $1B and over $4B in strategic acquisition and IPO valuation. He has held leadership responsibility for Regulatory Affairs, Intellectual Property, Marketing, Customer Service, and Operations across multiple medical device companies. He also serves as an Expert Witness for litigation involving medical devices due to his extensive expertise in devices and knowledge of the IP landscape.
Previously, he has been named inventor on nine issued U.S. and international patents and numerous patent disclosures and applications, and has served as a medical-technology and business expert in 37 legal cases involving patent infringement and product liability — including testimony before state, federal, and International Trade Commission courts. He is a recognized technical expert in ultrasonics, microfluidics, fluid dynamics, thermal tissue modification, tissue cutting/coagulation/ablation, endoscopy, and digital signal processing.
Hal continues to build, advise, and invest in the next generation of medical device companies.
Backstory
My career in medical devices has been defined by one constraint: a product doesn't matter unless it makes it all the way through development, regulatory approval, and into real clinical use. Early on I saw how often promising technologies died somewhere along that path — engineering, regulatory, manufacturing, or clinical reality.
Xinetix was built in response to that gap. Instead of focusing on a single product or company, I created a firm designed to take devices from concept through to commercialization — across the whole arc.
That experience defines how I operate at Suncoast. My focus isn't whether a device is interesting; it's whether it can be built, approved, and used in the real world — and what it will actually take to get there.
What I'm looking for
Medtech and devices with a credible path through development, regulatory approval, and real clinical adoption.
Founders who respect the whole arc — engineering, regulatory, manufacturing, and the clinic — not just the prototype.
