Hard requirements

Non-negotiables stated by builders in their own words. Miss one and they will not switch.

What the numbers suggest

11 rivals shipping (fact bar) see prices → market is crowded; differentiate on the unmet requirements above, don't compete on breadth.
3 builder posts asking · 3 different people (fact bar) see posts → demand is independently reported, not one person repeating themselves.
3 demand signals vs 11 shipping rivals → supply already outweighs demand — enter only with an edge.
0 willingness-to-pay quotes yet → no one has named a price — validate pricing before building.
last new signal 112 days ago → conversation is quiet lately.
