Personally, I subscribe to a waitlist of tools that can increase the efficiency of my work. And also tools to increase personal productivity (Notion like tools). I won't say there are VERY many of them, but if I come across a site with a good description, why not get notified when the product is ready.
I think anything is possible. There are an infinite number of options for starting a company, and a remote co-founder (or even a few) is not a problem, in case the cultural, ethical, moral code coincides.
So look for people who are close in spirit and vibe.
The best way of creating a landing page is making research and look throught 100-1000 great landing examples that are already work and look pretty good.
Just spend few day here at this curated and inspiration platforms:
1. SinteInspire
2. Land-Book
3. Lapa Ninja
4. GodlyWebsites
5. SaaSlandingPage
After that you will understand what type/structure/design/features/texts you need for your own product.
The only way to understand is to just do it.
