‘Call it cloning or call it inspiration, but good ideas don’t happen in a vacuum,’ says Klein. In 2002, he was living in America, where he saw the success of Netflix. When he moved back to the UK that year he decided to launch his own version: ‘Netflix was totally an inspiration. But we knew we’d need a different proposition, a different price point, a different market strategy. This isn’t like a Louis Vuitton bag being knocked off in China.’ Klein says that Lovefilm innovated, experimenting with selling DVDs as well as renting them, letting users trade discs and offering video games on its site. The company was bought by Amazon in 2011 for a rumoured £200 million. And OneFineStay is an example of a business that operates in the same sector as Airbnb, without ripping it off. Marsh came up with the idea independently, and focuses on very high-value properties, with a logistics business built up around them. ‘One of the things they say in investment is that ideas are cheap,’ says Marsh. ‘But you don’t need to copy and paste ideas — the fact is they tend to be current for other reasons.’
