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.
After the show
What happened next
According to GoNano's own account of the appearance, three Dragons made offers and the team accepted one. The specific amount and slice of equity in that agreement were never disclosed, so the ask remains the only hard number we can stand behind.
We checked the company site on July 23, 2026 and found it fully operational: quote requests, a dealer network you can join or search, and a listed phone and address. GoNano sells through quotes rather than an online cart, which fits a contractor-facing product.
Our read
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.
The reported result, three offers with one accepted, tells us the panel bought the story even if the final split never went public. What we would still want nailed down is which Dragon and on what terms, since the only account is GoNano's own. Treat the deal as company-stated until an outside byline confirms it.
A confident ask at a twentyfold valuation, with an unpublished close.
Worth knowing: The deal claim here is drawn from GoNano's own marketing, not a third-party report, so we treat it as company-stated rather than independently confirmed.
