For a hosting company my start with SiteGround was less than typical, as I somehow intruded on their company and client dinner at WordCamp Europe 2013. I was thoroughly sick through the whole WordCamp, so I retain no memory how that (and other things) happened. I am behind the lamps on the photo. Probably.
Some time later I migrated my sites to them and got to say they have one of the most interesting shared hosting options at the moment.
