What Happened to Flow Signals After Dragons’ Den?

Flow Signals appeared on Dragons’ Den in 2010, Series 8 Episode 1. The business was a light flash on a street traffic post. No deal was made — the Dragons decided not to invest. The business is still active today.

The Pitch

Derek Cozens walked into the Den in 2010 with a light flash on a street traffic post. They were asking for £50,000 in exchange for 10% 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 Derek Cozens left the Den without backing.

What Happened After the Show

Flow Signals is one of those Den stories that actually lasted. Having appeared on the show in 2010, 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 Flow Signals Still Available?

Yes. Search Techniques Limited appears to still be trading. Companies House records confirm the business is currently active.
