Warren Johnson argues that the clearest product-market-fit test is getting on the phone and trying to sell the product.
The brief
Warren Johnson describes how Plexor Labs works with domain experts who have valuable software ideas but lack the technical capacity to turn them into usable products.
AI coding tools may get a prototype most of the way there, but the remaining work—security, reliability, customer value, and willingness to pay—is what makes software sellable.
Plexor Labs uses discovery, specifications, documentation, and collaboration to build products while giving clients ownership of the resulting code and intellectual property.
Warren also reflects on Plexor Labs’ struggle to define its ideal customer, arguing that a clear beachhead matters more than pursuing revenue across every possible segment.
His sharpest test for product-market fit is simple: get on the phone and sell the product, because customer commitment beats abstract validation.
