Research method

How companies were included

We started with the 100Signals agency dataset, then required at least one public company source that names a project, client, or relevant delivery portfolio. A company’s industry label alone was not enough.

Descriptions separate observed evidence from our fit assessment. Vendor-published outcomes are not repeated as verified results. Missing rates, references, certifications, and technical detail remain visible as diligence questions.
