Before algorithms. Before automation. Before anyone was putting "AI-powered" in their product description — group purchasing organizations and purchasing cooperatives were already solving one of the most persistent problems in business: how do you get the best value out of every dollar you spend?
The approach, whether through a GPO serving private sector businesses or a cooperative serving public agencies and nonprofits, comes down to the same core idea: aggregate buying power across many organizations so that each one gets access to pre-negotiated contracts, vetted suppliers, and pricing that no single entity could achieve on its own. Less time sourcing. Less risk. More value.
That's optimization. It just didn't require a large language model to get there.
