Dragons' Den IndexUpdated 17 March 20266 min read

Green and cleantech is one of the smaller categories in Dragons' Den history, and one of the tougher ones to crack. Of the 34 pitches in our index, 13 secured a deal, a 38 percent success rate against the show's 30 percent average. Twenty-eight of those 34 businesses are still trading today.

Here is how the category has performed over the years, the biggest deal it has produced, who invests most in it, and which green and cleantech businesses from the pitches are still operating now.

Green and cleantech is one of the smaller categories in our index by pitch volume, with 34 pitches recorded, and its 38 percent deal rate sits closer to the show-wide average than to the standout categories, a reminder that sustainability-focused pitches still face a harder path to a handshake than most consumer categories, even as the sector has grown in prominence.

How Green and CleanTech Fares in the Den

A 38 percent deal rate is above the show's overall average of 30 percent, but only modestly so, placing green and cleantech firmly in the middle of the pack rather than among the Den's standout categories. Environmental and sustainability-focused pitches often ask Dragons to think in longer timeframes, regulatory shifts, infrastructure costs, payback periods, than the show's usual quick-turnaround consumer products, and that can make for a harder sell in a ten-minute pitch.

Where the category does stand out is deal size. The average deal in green and cleantech is £99,000, the highest average of any category in our index, ahead of tech and software and business services, which tie for second at £92,000.

The Biggest Green and CleanTech Deal in the Den

The largest deal in this category went to Pro Waste Management Services, which secured £200,000 for 40 percent of the business in series 6, jointly backed by Deborah Meaden and Duncan Bannatyne.

That two-Dragon backing is notable. Green and cleantech pitches with genuinely scalable infrastructure, in this case waste management, have historically attracted the kind of joint investment that spreads risk across more than one Dragon's portfolio.

Who Backs Green and CleanTech Pitches

Deborah Meaden is the category's most active investor, with three green and cleantech deals in our index, more than any other Dragon. It is a natural fit for her, Meaden has been outspoken about sustainability and environmental responsibility in business well beyond her time on the show.

Her deal count in this category, while modest in absolute terms given how small the sector is, still leads the field clearly. With only 13 deals out of 34 pitches, green and cleantech remains one of the harder categories in the index for a founder to convert, whichever Dragon they end up pitching to.

Which Green and CleanTech Businesses Are Still Trading

Twenty-eight of the 34 green and cleantech pitches in the index are still selling today, an 82 percent survival rate, a strong figure for a category that often depends on longer-term infrastructure and policy tailwinds to stay viable.

Among the businesses still operating are Mycorrhizal Systems, Reestore, Very PC, Rapstrap and Tiny Box, a spread that runs from soil science and refurbished electronics to sustainable packaging.

A Category Built for the Long Game

Green and cleantech pitches often ask the Dragons to think years, sometimes decades, beyond the usual Den timeline. Waste management infrastructure, soil science, refurbished electronics and sustainable packaging do not scale the way a viral consumer gadget can, and returns on that kind of investment tend to arrive slowly and steadily rather than in a rapid spike.

That likely explains the split personality of this category's numbers, a below-average deal rate paired with an above-average deal size. Dragons appear more selective about which green and cleantech pitches they back, but when they do commit, they commit meaningfully, treating it as patient capital rather than a quick consumer punt.

The Takeaway

Green and cleantech is a tougher category to land a deal in than most, a 38 percent deal rate against a 30 percent average, but the cheques that do land are among the largest in the Den, averaging £99,000. Deborah Meaden is the category's most consistent backer, and Pro Waste Management Services' £200,000 for 40 percent in series 6 stands as its biggest single deal.

The high survival rate of 82 percent suggests that once a green or cleantech founder gets past the initial pitch, whether or not they land a deal, they tend to stick around.
