Hey vfc1 great work. Couple of thoughts just on the landing page / proposal: 1 - It's an extensive landing page with a lot of scroll, I guess this might be because you're trying to talk about all the things you can do / will do which is extensive and great but I wonder if you can shrink the page to make the core points and drive to the call to action as a pose to scroll and depart.
2 - I suspect you'll have fairly long sales cycles right? It takes time for people to build their materials, gather resources, polish their words. I wonder if you can make them start with an initial step that builds ownership, e.g. upload a logo or something along that line that get's users along the way.
3 - It maybe apparent to users that you are new. Being new comes with advantages but people may feel the risk of you disappearing and or going bust. Is there a way you can communicate trust / long term support? Sometimes people do this with testimonials or perhaps some kind of of guarantee, maybe a lower priority one for consideration.
I wish you success. Have you ran numbers on your pricing? I would shift around the pricing moving the highest tier plan to the left and the $0 on the right. Conversions of the annual plan aren't really realistic until you have an established platform but you can have an expensive tier on the left as an anchor price and incentivize the middle tier plan.
Free is not a viable business model. If the going rate is $100/month, make something that is worth $400/month.
The problem is that free simply isn't worth it to anyone with a money making business. Because your platform is a dependency, a sustainable business model is important to business customers. If they are making money and have a following, your platform staying in business is worth a few thousand dollars a year.
Good luck.
