B2BEnrich vs StackDetect

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.

StackDetect detects and catalogs technologies used by websites, then lets users search, filter, and export prospect lists based on those technologies. It covers CMS platforms, WordPress plugins, ecommerce apps, analytics, advertising pixels, JavaScript frameworks, CDNs, payment gateways, CRMs, and more. Lead lists group websites by the tools they use for outreach, enrichment, or analysis. Each record includes a hostname, detected technologies and categories, confidence, HTTPS status, and last-seen date. Data comes from public pages through a browser extension and proprietary crawler; private or authenticated content is not accessed. The extension collects visited hostnames and detected technologies, not page content, form data, passwords, or personally identifiable information. Detection depends on public fingerprints and varies by technology; less-visited sites may have data weeks old. The free plan costs nothing and includes 50 technology lookups per month and sample lead lists. Paid plans include bulk exports and advanced filters; Business and Enterprise add CRM enrichment and API keys. Each API lookup uses one credit. Included API credits expire after 60 days; purchased top-ups do not.
