How this list was built
A company is on this list if LeadWave tags it as data centers, or its description or website presents cloud infrastructure, IT operations or monitoring software.
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.
