Klossal. It has many possible connotations.
If you are an Sales, Marketing or Brokering – it implies that you are very good at closing the deal.
If you are in Transportation or Guides or Telecoms – it could mean that the user is very close to something he is looking for.
Or it could sound like “Colossal” which is the perfect name for any startup that wishes to be a behemoth in the industry eventually.
