“What vertical can Crossbar serve as the financial OS for by embedding payments and capital through JustiFi?”
Evidence on Crossbar (www.crossbar.io) is extremely thin. The Crunchbase hit returned describes a company pioneering RRAM memory technology — which appears to be a different entity from the Crossbar listed as a JustiFi customer. The target (crossbar.io) likely operates as a vertical SaaS platform (plausibly construction or field services) that has embedded payments via JustiFi, but public footprint is minimal.
