The pitch
What walked into the Den
De-Fence is a physical deterrent system, a durable spike and barrier product built to keep pigeons and other pests off fences, walls and railings.
Andrew MacBain pitched it in season 11 from Vancouver, asking $50,000 for half the business at an implied $100,000 valuation.

What happened next
The product is still sold, as part of a larger business. It sits under MacBain's Pigeon Patrol brand, whose site was live in July 2026 featuring De-Fence with a buy call-to-action and a working shop, so the official home is the parent company's storefront.

The Hub verdict
De-Fence offered half the business for $50,000, a $100,000 valuation, and got exactly that. Jim Treliving and Joe Mimran came in together, a third Dragon joined the same deal, and the three of them split the half. A cheque that small pulling in three partners says they were buying a cheap option on a simple product rather than backing a company. The structural point matters more for anyone trying to buy one today: De-Fence is a product line under the Pigeon Patrol brand, not a standalone company, and the parent storefront is where it still sells in 2026.
Three Dragons took half the business for $50,000
Worth knowing: De-Fence is a product line rather than a standalone brand, so the parent company's site is its official home.
