Has your business had a game changer moment yet? On one of those nights out a fellow guest, arguably a little drunk, yelled out a question to the room and offered to give a piece of business (i.e. become a client) to anyone who could answer it. I knew the answer; the question was an obscure one about post offices, and I'm an expert on postal services having worked on the part-sale or privatisation of them in the '90s. He stuck to his word and gave me a piece of business. I'll never forget that. Knocking on doors led to many of my game changer moments too. Adolph Dassler, founder of Adidas, famously had a number of those moments - the first of which was giving free shoes to Jesse Owens, an American track athlete. Under the challenging prevailing political circumstances of the 1930s, the story goes that there was a risk involved in giving German products to an African-American, a man likely to run faster than Germans on their own ground and whose skin colour was the target of vile propaganda - but Owens famously wanted "those shoes, or none at all." Jesse was the most successful athlete at the 1936 Berlin Olympics, winning four gold medals. Word got around about the man who crafted his shoes with his bare hands - and when he formed Adidas in 1949, he was already something of a legend in the right circles. I spoke to some business contacts to find out what their 'moment' was. Alexandra Popa launched Bordelle in 2007, an upmarket underwear range which has graced global couture pages and bodies since its inception. Alex told me her big break came when she was spotted at a trade show in Paris and a substantial order was placed for the Britney Spears' Circus Tour. An order from Selfridges followed and within a day of her lingerie hitting the shop floor, they sold out. She now sells to over 30 countries and counts Lady Gaga and Rihanna as clients. "Before Britney we were a little known British brand but that order put on us radar of stylists and fashionistas on both sides of the Atlantic," she says. Manchester-born girls Helen and Lisa Tse quit their jobs to open Sweet Mandarin in 2004, selling their homes to open a Chinese restaurant. They recall their big game changer moment in 2009 beating 10,000 restaurants to win Gordon Ramsay's Best Local Chinese Restaurant on the F Word. "That put us on the map and now we have clients visiting us not just from Manchester but all over the world," she said. The second bolt came in the form of a successful Dragons Den appearance in 2012 when they pitched their gluten free, vegan sauces. As well as securing investment, they signed a national deal with 500 Sainsbury's and sold 20,000 bottles in the first week. Game changing - and life changing. At my current business, Target Parking, which manages car parks and provides facilities management in the UK, what game changer would move it on to the next level? A contract like Wembley or the O2. Shopping centres and theme parks with public car parks and in need of facilities management or security. Those are good pieces of business for us and while I've never been able to foresee that game changer before it hits, I know very well what it looks like and what it would mean to the business. Helen and Lisa did so by going on Dragons Den - and Alex did so when she took a stand "at a random trade fare" so early on in her business career. A roll of the dice or the patience and precision of a sniper. Game changers, quite simply - they change the game.
