In their own words
LeadBase
LeadBase is a paid web and API service that turns LinkedIn engagement into scored, enriched sales leads. It monitors posts for reactions, comments, and shares, then pulls profile details including title, company, experience, headline, and location. Users define ideal-customer criteria, and LeadBase ranks leads from 0 to 100. Enriched leads can be sent to Notion, Monday.com, GoHighLevel, or email; Notion and Monday.com are listed as available, while GoHighLevel is coming soon. The dashboard provides lead profiles, engagement history, export status, and search filters, with retention of up to one year depending on plan. Starter costs $49 a month, Pro $149 a month, and Business $449 a month. Enterprise and Organizations pricing is custom. Starter scraping pauses at its signal cap; Pro and Business charge overages. There is no free plan, and API access is included on Business.
LeadFlags
LeadFlags is a deterministic lead-scoring API and web service that filters fake, low-intent, and risky inbound leads before they reach a CRM or call queue. It returns a score, quality level, risk flags, positive signals, and a recommended routing action. Predefined rules give the same output for the same input, without AI, enrichment, or profiling. JSON requests have no fixed schema; field aliases and optional mapping overrides support nonstandard keys. The service can identify missing or invalid contact details, disposable email, suspicious messages, and inconsistent fields. It is described as CRM-agnostic, with HubSpot and Salesforce named as examples. Requests require an X-API-Key header; Bearer authorization is not supported. Starter costs €39 a month for up to 1,000 leads, Growth €99 a month for up to 10,000, and Scale €249 a month for up to 50,000. Enterprise uses custom billing and terms. Annual billing offers a 20% discount.
