A good design is important, so are the basic features which your app needs before it is launched.
With B2B apps being launched almost everyday, I never see thought being put into making it easier for people to switch from something they already use. If I already have a CRM system setup, please make it easier for me to try your software by providing a quick import.
I realise it’s difficult to have data import built for all the competition out there, but hopefully you consider building an easy way to import data from 4-5 top competitors.
Make it easy for people to switch to your product.
