B2BEnrich vs Wappalyzer

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.
