Dragons’ Den viewers have been left baffled by Thursday’s first pitch, as a couple hoped for investment for their ‘caveman’ business.

Husband and wife team Naomi and Dan went for an entirely different look on the competition, swapping suits and ties for ‘prehistoric’ outfits, a tooth necklace, and even going barefoot.

They even came in with their ‘cave children’, and began their pitch by asking for 40,000 ‘acorns’ from the Dragons.

‘We are the Stone Age company, and we deliver Stone Age education and workshops to primary school children,’ Dan explained.

Natalie went on to reveal their clothes were hand-made for living ‘in the wild’.

‘We’ve lived out in the wild twice, for around about a month, just surviving off the land,’ she said.

‘We hunted, we fished, we foraged, we slept in caves, and pretty much survived.’

They were then inspired to set up their company, and deliver education and experiences to children around the country, which they entered the den with the hopes of gaining an investment to expand.

As Deborah Meaden admitted she ‘connects with the Earth’ in a similar way by going barefoot too, Peter Jones was left remarking: ‘That’s really weird.’

But she wasn’t too happy about their ‘stone age budgeting system’, as the couple failed to impress with their numbers.

‘Currently we live in a static caravan in my parents’ driveway so we’re not paying rent and we can practice living sustainably,’ Naomi revealed.

‘We live pretty frugally,’ she added, before saying they’ve made it this far thanks to ‘friends and family’.

But viewers were entirely baffled over the business.

‘What?????’ @BurySue questioned, while @born_comedian blasted: ‘Are they taking the p**s?’

‘The first pitch tonight and looks like The Flintstones have entered the den,’ viewer Kevin Astley wrote on X.

‘Am I watching Dragon’s Den or The Flintstones?’ Lucy Taylor added.

‘This is a p**s take,’ @darrenbizzle2 slammed.

@swilliams73 added: ‘I haven’t stopped laughing yet. Oh damn. I honestly can’t believe this is for real.’

Despite the couple’s passion in their business, and Steven Bartlett calling the cause ‘important’, all five Dragons were out, and they left the den without an investment.

Nonetheless, Dan and Naomi did gain the promise of some help from Peter, and were left saying, ‘We still win,’ as the Dragons praised them for ‘living their passion’.

‘They gave us hope in a way,’ Dan told the camera.

‘We can continue being us,’ Naomi added.

Dragons’ Den airs Thursdays at 8pm on BBC One and iPlayer.
