As part of his Launch Me competition, entrepreneurs have the chance to sell their business to the ex Dragon. If you're not sure how much you can say in six seconds, check out Richard's own vine here.
From the videos, Richard will choose the three best entrepreneurs and invite them into a live Google+ Hangout. In the Hangout, the three will have to convince Richard why they deserve his money.
As well as the £10,000 loan, the winner will gain ongoing business advice from the Dragon and enjoy a private lunch with him.
Six seconds to sell
So, get thinking of how you can sell your business in six seconds. With so little time, will you concentrate on your idea, your marketing or your business plan? What else can you show off in the video? You may not be able to fit a lot of words into six seconds, but there are other ways to show off your business.
When your video is ready, tweet your Vine using the hashtag #S4SLaunchMe before the 28th of May.
