The lesson
Let three real product screenshots with a short caption each do the selling; keep the paragraph copy to one short intro.
A large "Validate" title and the line "Validate your product ideas faster and with confidence" lead. Below, three UI crops zigzag down the page, each beside a short heading: "Easily input product ideas", "Share ideas with customers, in-app" and "See deep analysis of the data". The last is an Idea Poll bar chart of votes.
The abstract pink and purple shapes at the top add nothing for a reader; skip them. Keep the screenshot-plus-caption pattern, and use screens from your own product.
