Full disclaimer I am a huge fan of Linear's philosophy and products.
What I suspect Linear doesn't notice; the thing that makes their lives easier; the David Foster Wallace water they swim in everyday - is they're their own customer.
Most software makers have to translate requirements between domains where terminology is incompatible, dogfood to find the micro pain that helps a product become great, etc. but Linear can just... track the build of Linear in Linear.
When the someone behind the software is its customer they'll get loads of judgment calls right first time. Great!
If you aren't your own customer but plan to leverage intuition, plan on being wrong lots- and keep your company and architecture and products compatible with frequent wrongness so once discovered you can pivot to the right thing. No ego.
