slightly tangential, but where do people get awesome landing pages like linear(https://fig.io/. has similar landing page) etc. Do they build them in-house or buy templates somewhere? Many of the recently launched YC companies have awesome landing pages. eg. https://automorphic.ai/,
I guess people get awesome landing pages the same way they get any other pages :-)
* either build them in-house if there are skills;
* or buy a template and customise it;
* or hire a designer/developer/team to do it. The awesomeness of the result directly depends on clarity of requirements, I think.
As an example, I recently designed a website for BinaryNights [0], and we did use Linear.app as a starting reference, but during the discussions quickly shifted towards more minimalistic approach.

A lot of them pay external design houses to do it. There are several design houses that I know of that are ex YC founders so the connection is already there.
