I have used craftwork design method framework to build startup landing pages and websites. https://craftwork.design/downloads/method-4/ https://craftwork.design/downloads/method-4/ It ships with many layouts, blocks and components in React that you can mix and match for building landing pages. If building a page from scratch isn't in your wheelhouse it's quite useful to get something out quickly.
