Feedback on Simple Portfolio's landing page and copywriting

Hey, I just launched Simple Portfolio (in closed beta but with a public live demo) and would appreciate your feedback on the copywriting and UI of its landing page. Is it clear what it does and what problems is it trying to solve? Is the wording good?

Also, any thoughts and feedback on the product itself are welcome.

And finally, I am looking for beta testers so if you are a passive investor and would like to give my product a try, let me know!
