The pitch
What walked into the Den
Jonathan Duquette runs GoNano out of Mirabel, Quebec, and its product is a nanotechnology spray built to preserve roofs and stretch out how long they last.
He came to Dragons' Den Canada in Season 20, episode 4, which aired in 2025, with a big number in mind: $1,000,000 in exchange for just 5% of the company. That ask pegged GoNano at a $20,000,000 valuation, an ambitious figure for a coatings business.

What happened next
According to GoNano's own account of the appearance, three Dragons made offers and the team accepted one.
GoNano sells through quotes rather than an online cart, which fits a contractor-facing product.

The Hub verdict
Set the numbers side by side and the ambition jumps out. A $1,000,000 request for 5% prices GoNano at $20,000,000, and that is before a single Dragon has spoken. For a roof-coatings business, holding out for a twentyfold multiple on the cheque is the aggressive end of the room.
Three Dragons put offers on the table and the team took one, so the panel bought the story even at that price. The business sells through quotes and a dealer network rather than a cart, which fits a contractor-facing product where every roof is measured before it is priced, and it is what makes a twentyfold ask arguable in the first place: one national dealer agreement is worth more than any volume of direct orders.
A twentyfold ask that still drew three offers
