Coresignal vs Grizz Company Enrichment API

Coresignal provides real-time, multi-source public web data about companies, jobs, and professionals through APIs and flat-file datasets. It says its coverage spans 4.5 billion records from more than 15 sources. Dataset formats include JSON, JSONL, CSV, and Parquet. Data is offered at Base, Clean, and Multi-source processing levels; the Multi-source option combines and enriches material from multiple public sources. Its API catalog includes company, employee, and jobs endpoints with search, collection, bulk collection, and enrichment functions where applicable. Listed integrations include MCP Server, n8n, Zapier, Clay, Databricks, Google Cloud, Amazon S3, Snowflake, and Azure. Coresignal identifies investment, sales technology, HR technology, and market research as customer areas. It says it collects publicly available business data, excludes private or sensitive data and login-secured areas, and aligns its privacy policy with CCPA and GDPR. The free tier gives 2,000 credits for a 7-day trial, issued once per company email domain. Paid plans start at $49 a month.

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.
