Ocado, the online grocer, is close to completing its seventh fundraising  for £40m, with the backing of Tetra Pak billionaire Jorn Rausing. The firm , valued  by some at around £600m, is still to make a profit, but is planning on a stock market flotation in the next eighteen months to fund an international expansion.  An IPO could generate  £130m for owners Jason Gissing, (pictured) Jonathan Faiman and Tim Steiner.
