I am undecided whether I would prefer the logo to use the "@" symbol or to have the business name in full e.g. "Resolution at Work". I would love to see more concepts where designers do NOT use the "@" symbol and instead use "at", as I think this will open up more opportunities for a creative abstract mark to be developed such as the Thomson Reuters logo.
Other logo examples I like include:
Black Horse (sophisticated, good image and colour choice, modern font):
