I don't mind giving my email or making an account after I have any inkling that the product might be worth deleting a few spam emails. Neeva was giving me a modal popup in my first minute; that's never going to get my email.
(Founder of Neeva here) Appreciate the input and hear your frustration. This is a carryover from changes we made to introduce the free tier earlier in the quarter. We are making imminent improvements on modal frequency and getting them out of your way. Stay posted.
