B2BEnrich vs Grizz Company Enrichment API

B2BEnrich provides real-time B2B data enrichment through a REST API and web interface. It can turn emails, phone numbers, and profile URLs into professional profiles with job, company, and contact details. Company enrichment returns firmographic information such as industry, revenue range, employee count, headquarters, funding history, and technology stack. The service says its database includes more than 550 million professional contacts and 50 million companies. Email validation includes SMTP-level checks, deliverability scoring, disposable-address detection, MX validation, and breach-history checks. Requests and responses use JSON; the API uses API-key authentication and HTTPS encryption. CRM integrations include HubSpot, Salesforce, and Pipedrive, with Zapier, Make, or direct API connections available for other CRMs. The free plan includes 50 credits per month. Starter costs $49 a month for 2,000 credits per month, and includes a 7-day trial. Rate limits apply, and high-volume users can contact B2BEnrich about custom limits.

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.
