When you're setting up with Hike you'll come across a section where you have to enter your company information. We use this information for local SEO actions.
Towards the bottom of the page you'll spot that you have to assign a category. It looks like this:
If you can't find a category that is specific for your brand then choose one that is more general.
For example, there isn't an option for "SEO software". But they do have "Internet Marketing Service" which is what I'd select for Hike.
So, go more broad until you find something that is suitable.
Also, don't fret too much about this as it is only an ancillary piece of information we need; it will not make or break your SEO!
