To be a designer today is to be an entrepreneur. Whether you're a two-man operation in Shoreditch or a 3,000-person, vertically integrated brand, you need to have the wherewithal to run your business through investment, considering everything from start-up funds to your exit plan or what it takes to go public.

If you're a teenager in Palo Alto launching an app, you know from the outset how you plan to finance your business.

Can we invest?' in the same way that, now, if you were to say, 'My nephew is starting a mobile app,' everyone would say, 'Oh, smashing! Can I invest?'
