What the numbers suggest

3 rivals shipping (fact bar) see prices → competition is thin; attack the weaknesses builders quote above.

4 requests from 4 different people (fact bar) see posts → demand is independently reported, not one person repeating themselves.

1 new tracked post (all types) in the last 30 days vs 3 the month before see the curve → demand is cooling.

4 demand signals vs 3 shipping rivals → demand and supply are balanced — differentiation decides.

0 willingness-to-pay quotes yet → no one has named a price — validate pricing before building.
