I like what you have done with 21 as it is different. I like the way SaaS stands out as out customers will know what SaaS means. Can you do a design where the i goes under the SaaS
"Software as a Services" is always written like that
not positive I understand but I think this is what you mean.... questions. 1. is it Service or Services? I think it should be singular because of the "a" but you reference both ways.
2. You mentioned possible other fonts - are there particular fonts you like? or font styles you like?
