Dastiger Khan, Rahul Malhotra, Harmeet Chauhan, and Baltej Sandhu, from Waterloo, Ontario, asked for $100,000 for 5% equity in Guard-Ex, which is developing a headset device using vital signs and machine learning to detect drug impairment, measuring eye movement, body temperature, brain activity, heart activity, and muscle activity. The team has spent about $15,000 so far building a second prototype, has consulted an optometrist from the University of Waterloo on the eye-scanning component, and has spoken informally with police officers from York Region and Peel Region, with a commercial pilot targeted for the following year.
Vincenzo Guzzo declined, estimating the validation, legal, and court costs to reach $5 million to $7 million. Jim Treliving, Arlene Dickinson, Manjit Minhas, Lane Merrifield, and Michele Romanow made a joint offer of $300,000 for 15% equity, which the founders accepted.
