1) Your page assumes too much (it assumes I know about the product). It does not speak to me directly. EVERYBODY and their donkey makes plans, but who, what, how why will use you? For example, if this was for travel plans, I'd say "Taking the next trip, let us be your assistant (the value prop is not a place to write - a paper and pen can do that - it’s the benefits of having an assistant)."

2) That image makes it look difficult/techy product to use. You’re saying I will be using the tools NASA scientists use, that makes it not easy for me to do.

3) Your round logo makes you look old, not you age wise, but it makes your company look like something from the 80s. Like a soap bar logo. Look at the top 10 companies your customers like or use, and take hints from their logos. Honestly, I don't know why companies need a logo, just use a short form of your company name in its colors (hint: look at the top left corner of this page).

4) I said I wouldn’t pander but I can't help but say that your blog is awesome!

5) Inviting people to the launch party? That’s the benefit? But you’re not desirable enough (yet) for me to give up my email address for the opportunity to hang out with you.

6) For enticing people to sign up, I’d say do this: Give a solid value prop in your landing page so anyone who reads it wants it immediately! Then offer your service free for a limited time or something. This will do 2 things, first it will force you to sell your product/service in a sentence, second it will keep out people looking to get something free off you instead it will entice get people who are actually excited about using your service to try and get in - they will be your word-of-mouth army.

7) Add a descending counter (15 invites left) etc. to create a sense of urgency.

May you have great success!
