Green & CleanTech is one of the most-pitched corners of the Den. Across 21 seasons, 34 green & cleantech businesses have made the walk down the hallway, which makes it the number 7-largest category on the show. All that volume means the dragons have seen every version of the green & cleantech pitch, and that raises the bar for the founders who break through.

Of those 34 pitches, 13 closed a deal on air. That is a 38% success rate, comfortably above the show-wide average of 29%. The dragons clearly like this category. The products are easy to understand, easy to demo, and easy to sell. The average green & cleantech check came in around £99K.

The biggest moment in the category so far was Pro Waste Management Services, which landed £200,000 for 40% in Season 6. Deals that size are rare anywhere on the show. They happen when a founder shows up with real revenue, a product the competition cannot easily copy, and numbers that hold up under a grilling. The rest of the top of the list tends to share those traits, so it is worth studying if you want to understand what a winning green & cleantech pitch actually looks like.

Deborah Meaden has been the most active dragon in green & cleantech, taking part in 3 of the category's deals. If you were a green & cleantech founder, that is the dragon you would want to aim your pitch at. Dragons gravitate to the categories where their own retail relationships and operating experience pay off, and the deal history makes those preferences easy to see.
