What are your must-have sections for a landing page?

Hello guys, Let's say you are going to launch a new product on PH, and you are going to create a new landing page for it, what must-have sections do you think should be included in the landing page? For me, it's: - Hero - Features matrix - Social proof - Pricing/Payment - CTA Other sections I might consider: - Gallery carousel - Founder letter - Logo clouds How about you? I would greatly appreciate it if you could provide me with feedback on EarlyBird (https://earlybird.im), the product I am working on so that I can make improvements.
