Tool

Lead Finder

If your product integrates with or replaces a specific technology, the fastest path to qualified leads is finding companies that already use that technology. Technographic data — what software and tools a company runs — is one of the strongest buying signals available because it reveals both technical readiness and budget allocation.

ToolRouter's Lead Finder can search for companies by their technology stack, identifying organizations that use specific frameworks, platforms, cloud providers, or SaaS tools. The find_companies skill filters by technology usage combined with other firmographic criteria to produce highly targeted prospect lists.

This approach is especially effective for developer tools, integration platforms, migration tools, and any product that replaces or complements an existing technology. Companies already using a related technology are pre-qualified in terms of budget, technical sophistication, and use case fit.

Claude finds companies using specific technologies and helps you evaluate them as prospects through conversation.
