Grizz Company Enrichment API vs Melissa Enrich

Grizz Company Enrichment API accepts a company name or domain and returns enriched company information. Documented fields include company name, domain, NAICS code, location, ERP and ATS signals, and, when available, employee range, address, phone, email, LinkedIn URL, and an AI-generated description. Existing database matches return immediately; unknown domains are scraped and classified with AI, typically within 60 seconds. Requests use an asynchronous submit, status-polling, and results-fetch workflow, with a bulk endpoint for completed unretrieved requests. Organizations have a monthly call limit set by Grizz, and the bulk endpoint returns up to 100 records by default, with 500 as the maximum. The API is in beta, so endpoints, fields, and rate limits may change. It is aimed at construction technology sales and marketing teams, tracks more than 100 construction technologies, and refreshes technology signals weekly.
