Company SaaS Checker API

Qualifying software companies before outreach prevents wasted prospecting cycles on businesses outside your addressable market. The Company SaaS Checker API analyzes domain characteristics across CUFinder’s 85M+ company database to determine whether a company operates a SaaS business model, returning boolean classifications with confidence scores and supporting indicators like subscription pricing signals and cloud infrastructure deployment. Built for sales intelligence platforms, market research tools, and vertical-specific prospecting systems, this RESTful endpoint delivers SaaS classification data—including product delivery model, pricing structure indicators, and technology stack markers—that power ICP filtering, competitive landscape mapping, and partner ecosystem identification workflows across your go-to-market operations.
