Congratulations on launching, and having the confidence to put your product out there in front of potential customers. You're already farther along than about 80% of other startups.

Positives - You have a nice website and a good looking product, your message is clear, and there's no reason why startups, especially those that aren't 'design lead', won't buy. With more templates for different verticals you could build something big.

Negatives - Your first target market is poor and has relatively few customers. I would highly recommend considering a tiny pivot to aim more at middle managers who are presenting but want something better than powerpoint's builtin templates. There are tens of thousands of those presentations happening daily. I reckon there's a massive opportunity there.

Also ... I was extremely fortunate to attend a workshop by Nancy Duarte (http://www.duarte.com) once - I would really recommend looking through her portfolio and reading things she's written about presentation design. My pitch decks are about 1000* better now.
