I am not experienced with startups and funding. I am experienced in 'selling' my ideas to clients or executives. So I dunno if this advice is relevant or not to your situation. Its certainly relevant to general principles of clarity and communication, which, hopefully, is relevant in most fields, even silicon valley startups.

To improve your landing page I would..

immediately establish the following points as tersely and clearly as possible, ie If you can do one of them with 4 words great!.

1. Whats wrong with conventional dog food

2. Whats your better idea

and then, smaller, slightly more detailed points..

3. Very briefly whats your plan to make this happen.

4. What do you need to carry out this plan

I would also, eliminate any cruft that isnt really saying anything that isnt necessary eg. this whole paragraph

" How am I going to do it? I'm going to use my software engineering and entrepreneurial experience. My technical experience goes pretty deep, well beyond just a software engineer. I can do things with a computer not even I understand. This gives me an edge over a lot of things. When I want to learn something I just do it. So here I am. "

You dont need to say "hey I'm a good software guy".

If you propose this idea well, readers will assume youre capable of carrying it out. No-one will ever state the negative of that eg. "I'm a really bad unreliable lazy worker and I dont care about this" so you dont need to state the positive.

Also dont say youre good and enthusiastic, show them with a clear impressive presentation.

Overall imo the site is too conversational while also being too light on actual information, its like youre waffling.
