Then your question is less about what the new brand ought to be and more about how to implement the rebrand during your transitional phase.

Some of your concerns should center around changing the name in social media handles, within your website's domain, and in app store and other listings.

Mainly that's an SEO issue, since back links are affected. So you'll want to talk to an SEO agency with a track record of shepherding websites through domain changeovers. Don't forget about email forwarding, by the way.

Really, changing names online is a common occurrence; and, properly handled, any dip in rankings ought to be minimal and temporary (assuming there is a dip at all). For a well conceived rebrand, the rebound will more than make up for that.

Apart from worrying about search engines, social media profiles, and your various directory listings – which is about as complex as moving from 1 apartment to another – you'll want to think about human customers.

Naturally, you'll want to inform them about your rebrand. Timing that is important. So is spin. A name and image change by itself is disruptive. People who think they know you already must be convinced to meet you afresh. It's important to persuade them that this transformation is a justifiable improvement and that it signals improvements for them as well. I recommend including your audience in the transition and leveraging the rebrand as a PR opportunity.

One last thing ... Before you commit resources and time to the new brand name or fully abandon the old one, talk to someone with naming expertise. Think of it as a home inspection before you sign off on a mortgage and move in. Maybe you already hired a professional, but an independent opinion wouldn't hurt. Probably everything is ok. Still, you never know what little things might cause friction. And having confirmation that everything is ok is worthwhile in its own right.

Honestly, I cannot advise you on the SEO or social media transition. But I can definitely inspect your new brand name before you get underway. Most likely your branding guidelines already include a strategy for pitching the new name to customers new and old, but if there are any gaps in those guidelines I can offer feedback there too.
