This year’s MN Cup wrapped on Monday night, and AcQumen Medical, a medical device company in Minneapolis, walked away with the $50,000 grand prize.

AcQumen presented its UltraTrac invention to a review board at the McNamara Alumni Center. The device uses electrodes and ultrasound technology to monitor infants’ blood flow. Market need has emerged due to the bulkiness of existing monitoring equipment, per a statement from a MN Cup spokesperson. Such equipment is difficult to use on especially small babies.

UltraTrac’s solution marks “a groundbreaking step toward lowering infant mortality,” the spokesperson says, intended for even the smallest infants.

MN Cup rallies early-stage entrepreneurs from across Minnesota, and this year’s contest drew more than 3,600 entrants, per a press release. Business ideas span nine divisions, including “Energy, Clean Tech, & Water” and “Food, Agriculture, & Beverage.” In the previous round, AcQumen won in the “Life Science & Health IT” division.

AcQumen co-founder and CEO Dori Jones now gets to decide what to do with the winnings, awarded as seed money for growing the business.

Last month, Jones also earned a Top Innovator Award for “best seed track presentation” at the New York Venture Summit, according to an AcQumen Facebook post, where judges’ feedback highlighted the company’s “traction with clinical partners.”

Launched in 2005 by local entrepreneurs Dan Mallin and Scott Litman, MN Cup has awarded more than $5.8 million to Minnesota startups, according to the release. Each winner of MN Cup’s other eight divisions has earned $25,000. The “Youth” division winner has received $10,000, with semifinalists in that category taking home $10,000 divvied among them. Last year’s grand-prize winner was Momease Solutions, developer of a lactation-boosting pumping bra.
