LLM-Based Company Enrichment Costs ~$0.01 Per Firm, Skipping B2B Data Vendors

A developer found that most B2B enrichment data — such as business model, pricing, and target customers — is freely available on company websites, making paid per-credit enrichment services largely redundant. By pointing a large language model at a company's homepage and a few key pages, they built a pipeline that extracts structured firmographic data into a fixed JSON schema. The tool costs roughly one cent per company using a small model like GPT-4o-mini, compared to $0.75–$1.50 per row charged by commercial enrichment platforms. Key failure modes include occasional hallucinations — mitigated by requiring the model to return 'unknown' when data is absent — and JavaScript-heavy sites that render no content without a headless browser. To limit compliance risk, the system is restricted to generic company emails rather than personal contact details.
