John Barstead and Mark Tracy walked into the Den in Season 5, Episode 8 in the episode that aired 10 December 2007. Dolphin Alarms, the alarms for swimming pools, pitched in the Other category, one of 902 other businesses to brave the Den across all 21 seasons.

The dragons passed, and Dolphin Alarms left without a deal. That's not always the end of the story. Some of Dragons’ Den's most successful companies were rejected on air and grew anyway, using the exposure (the "Dragons’ Den effect") to drive sales the dragons missed out on.

Dolphin Alarms was one of 79 businesses to pitch in Season 5, where 15 deals got done. In the Other category overall, roughly 11% of pitches have landed a dragon across the show's history.
