The jaw-dropping story of the spectacular rise and dramatic fall of British music and festival company Pollen. The company was launched in 2014 by two young British brothers, Callum and Liam Negus-Fancey. Riding the wave of the tech boom which saw start-ups like Deliveroo, Airbnb and Uber become ‘unicorn’ giants valued at $1bn or more, the brothers created a simple idea that soon attracted huge investment. Beginning as a ticketing platform – giving festivals goers the chance to earn VIP rewards for selling tickets to their friends – the company tapped into a lucrative area when music festivals and Instagram influencing were flourishing. They promised their customers a ‘bigger life’, gave staff a glamorous, party-fuelled workplace and soon went global.
