One of the other benefits of a new gTLD is it shows you are ‘down with the kids’ or at least in touch with the potential of online. In terms of choosing a domain in the modern social media driven world, shorter is better too. Every character in your domain name is likely to eat into your social media sharing character allowance and with Twitter still at 140 characters, every one counts.
As a new generic top level domain, the .XYZ is a great option for start-up projects with many exciting name combinations available. That gives you more chance to be creative with your naming choices too. .XYZ also has the connotation of a being a destination domain. Can you build that into your business branding? Could .XYZ hold the key to your successful future?
Even if your project is just at the idea stage, .XYZ domain names are priced to enable speculative investments affordable for all. Building a brand is all about building engagement with your potential audience and if that is fellow start-ups, what better domain to choose than a start-up domain?
