How this list was built

A company is on this list if its headquarters, as recorded in LeadWave's database, is in Houston. Different spellings of the city count as one, and so do its districts: Brooklyn and Manhattan are part of New York City.

The data comes from LeadWave's database of SaaS and AI companies, last updated in October 2026. Companies that share a website are counted once. Headcount, funding and CEO come from public sources, so some fields are blank for smaller companies.
