Defining your product
Be different! You can be simpler, cheaper, faster, more robust, more fun, more beautiful, weirder.
Differentiation first, then feature parity (copying features from competitors). Make your product unique.
Focus on a small set of features (small scope), but do it well.
Can you even fit the core features on your landing page? Then you can build a Landing Page Product (LAPP).
From the user’s perspective, a bad user experience design (UX) is the same as a buggy/faulty product.
