I think a lot of people don't grasp the extent to which the cost of founding a tech company has fallen since the dot-com boom. I remember forking out tens of thousands of pounds for physical hardware (which then had to be hosted somewhere) and software licences for things like Oracle and Checkpoint firewall, which I then had to install, set up, admin and maintain. These days, with Google, AWS, Rackspace, Heroku, there's none of that. You can spin up a new server in minutes and scale up as required. All the technical infrastructure is already there, so you can focus on the product and market.
