Marketplace and brokerage businesses live and die by one thing: matching a supply side and a demand side reliably, then managing everything that happens between the two after the match is made. Qualix has built inside two very different versions of this problem, a household staffing marketplace connecting candidates and clients, and an internal platform managing broker relationships in a perishable goods supply chain. Both required software that could handle two sides of a transaction with different needs, different incentives, and different data, without forcing either side into a workflow built for the other.
