How this list was built
A company is on this list if LeadWave tags it under customer support, chatbots, call centers or knowledge bases, or its description or website presents a support product.
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.
