Placeholder. Two completely independent teams — one in Italy building diaper-core hardware (GDM) and one in the US running premium DTC brands (Coterie) — converged on the same idea (radically thinner cores, up to 40% less material) from opposite ends of the supply chain, one as a B2B component seller and one as a consumer product.

What we've found so far: GDM's 'Extra Thin Core' component technology claims up to 40% material reduction; Coterie's consumer-facing 'The Diaper' independently achieved similarly high absorbency-to-thinness ratios.

Open research: Trace GDM's actual customer list (which consumer brands license this core tech); determine if Coterie is a GDM customer or built proprietary tech; interview both companies.
