What Happened to Respi Vest After Dragons’ Den?

Respi Vest appeared on Dragons’ Den in 2005, Series 2 Episode 6. The business was a vest aiding breathing muscles. No deal was made — the Dragons decided not to invest. The business is still active today.

The Pitch

Dr Mike Caine walked into the Den in 2005 with a vest aiding breathing muscles. They were asking for £100,000 in exchange for 20% of the business.

Despite their best efforts, the pitch didn’t convince the Dragons to open their wallets.

The Deal

No deal was made. The Dragons weren’t persuaded to invest, and Dr Mike Caine left the Den without backing.

What Happened After the Show

Respi Vest is one of those Den stories that actually lasted. Having appeared on the show in 2005, the business has now been trading for over two decades — an outcome that puts it ahead of the vast majority of startup ventures, let alone television pitches.

Is Respi Vest Still Available?

Yes. Progressive Sports Technologies Limited appears to still be trading. Companies House records confirm the business is currently active.
