Ask HN: Should my company name specify the type of service I provide?

I'm about to register a limited company, get a company bank account etc, so I need to get my company name right.

I'm building a SAAS product, which may be the first of many, so I have one company name under which all of my products will be sold (obviously with a seperate website for the product so it can be properly marketed). This is the sort of thing I want to do going forward - build my own products and sell them.

So my question is should I register my company name as "CompanyName" or should I add "Software" afterwards so it's clear that i'm in the business of selling software? I.e. I would instead register "CompanyName Software"?

I noticed Patrick from Kalzumeus has registered with the "Software" addition, as have others.

I'd prefer to just register as MyCompany as it's shorter, snappier and allows me to change direction in future. Adding Software does however create less ambiguity over what my company does currently... What's the best move?
