Jonathan Duquette, founder of GoNano in Montreal, Quebec, asked for $1,000,000 for 5% of his company. GoNano uses nanotechnology and bio-oil sprayed onto asphalt shingle roofs to restore and extend their lifespan, with treatments costing about 80% less than a full roof replacement and taking about two hours to apply. The company sells through a network of over 270 dealers across North America, who pay $20,000 for enough product to generate about $35,000 in resale revenue, and signs about 30 new dealers a month. Sales were $1.6 million in 2023, $4.9 million in 2024 with $1.4 million in profit, and the company was tracking toward $6 million in sales and a projected $15 million for the current year, with an expected $5.5 million in earnings.

Wes Hall offered $1,000,000 for 10% with a provision preventing outside capital raises for two years, and Manjit Minhas offered $1,000,000 for 6% equity plus a 2% royalty until she doubled her money, but both were withdrawn once better offers appeared. Brian Scudamore went out, saying he struggled to understand the value proposition after finding skeptical reviews online. Arlene Dickinson went out, arguing the business was already profitable and did not need the investment. Michele Romanow offered $1,000,000 for a 5% perpetual royalty, which was negotiated down with Jonathan Duquette countering with 3% equity or royalty options, ultimately landing on $1,000,000 for a 3% perpetual royalty with no equity, which Jonathan Duquette accepted.
