Common questions
Is it really free?
Yes. LeadScan is completely free — no account, no credit card, no rate limits. The web app and CLI both work without signing up.
How does tech detection work?
LeadScan fetches the company's public homepage and reads the raw HTML, JavaScript bundle names, meta tags, and HTTP headers. Over 40 technology fingerprints are matched entirely client-side — no third-party APIs.
Does it work for any company?
Any company with a publicly accessible website. If the site blocks scrapers, uses heavy client-side rendering only, or requires authentication, the scan may return limited data.
What's the conviction score?
A 0–100 number that weights four dimensions: tech modernity (25%), growth signals (35%), market presence (20%), and contactability (20%). Higher = stronger sales target.
How does AI outreach work?
Outreach is generated by Llama 3 via Groq. It uses the company's tech stack, growth signals, industry, and your target role to write a cold email, LinkedIn message, and call opener specific to that company.
Can I use the API directly?
Yes. POST to /api/analyze with a domain field, or /api/outreach with domain, role, and product. No auth required. See the Docs page for the full schema.
