Dragons’ Den Season 15 Recap: Every Deal Worth Knowing

Series 15 of Dragons' Den, first broadcast 2017 to 2018, put 58 pitches in front of the panel. 26 of them walked out with a deal, a strike rate of 45 percent, and the Dragons collectively put about £995K behind the businesses they backed.

Series 15, broadcast across 2017 and 2018, produced the sharpest single-season jump in this run, with the deal rate climbing 15 points on the year before.

Across the 22 series in our index, series 15's total investment of £995K ranks 5th highest, and its 26 deals rank 7th highest by count. Those two rankings don't always move together, since a series can rack up a lot of small deals or a handful of large ones, and series 15 sits where it sits on both counts.

How many pitches got a deal in series 15?

Of the 58 pitches that appeared in series 15, 26 secured investment, for a deal rate of 45 percent. That climbed sharply compared with the 30 percent deal rate the series before it, which gives a sense of how choosy, or how generous, this particular panel of Dragons was being that year.

None of this means the other pitches were bad businesses. Dragons' Den has always turned down founders who go on to build successful companies without a Dragon's money, and it has funded some that later folded. The deal rate measures what happened in the room, not how the businesses performed afterwards.

It's also worth reading the 45 percent figure alongside the raw count. 58 pitches is a leaner field than the biggest series in this index, so the same deal rate can represent very different numbers of actual businesses funded depending on how many founders got through the door that year.

The biggest deal of series 15

The biggest single deal of series 15 went to Mo Bros, which secured £150,000 in exchange for 20 percent equity. The investment came from Peter Jones and Tej Lalvani.

A 20 percent stake for £150,000 values Mo Bros at roughly £750,000 at the point of the deal, the kind of valuation math that plays out on screen every time a Dragon and a founder haggle over percentage points.

That single deal accounts for a meaningful share of the series' total investment: £150,000 of the £995K the Dragons put into series 15 overall went into just this one pitch, which is a useful reminder that a series total is rarely spread evenly across every deal made.

What the Dragons backed most in series 15

The categories that did best with the Dragons in series 15 were Other, Food & Drink and Tech & Software. 'Other' topping the list is normal for this show: Dragons' Den pitches cover everything from kitchen gadgets to fintech apps, and a large share of any series doesn't fit neatly into a single retail category.

Beyond that catch-all, the categories that stood out say something about what founders were bringing to the Den that year, and which of those ideas the panel judged worth backing.

Food & Drink taking a top spot in series 15 lines up with the kinds of products that tend to translate well to a live studio pitch: something the Dragons can hold, taste or try, rather than a service they have to take on faith.

Dragons' Den success is not measured only in who gets a deal on the night. Some of the strongest survivors from any given series turned down an offer, or never got one, and built the business anyway. Deal or no deal, survival past broadcast is the harder test.
