Unfortunately I'm going to be a wet blanket: I've signed up on Zoho a bunch of times over the years but never stayed because of the Zoho design, or lack thereof. The text is too small, the fonts and icons are ugly or amateurish looking, and its not mobile friendly.
Look, I want you guys to win. I can't stand Salesforce. I'd rather use Zoho products than Google products, but please give some attention to your UX/UI.
Thanks for listening!
