In their own words
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.
Leadspace
Leadspace provides real-time B2B data intelligence to help organizations identify buyers, prioritize opportunities, and execute go-to-market strategies. It combines CRM, marketing automation, product data, or data lakes with more than 30 embedded third-party B2B data sources. The platform creates unified company and contact profiles that can include buying centers, technographics, intent, and firmographics. AI captures firmographic, technographic, behavioral, and intent signals, then uses models to score fit and intent and prioritize leads. Enriched intelligence can be sent to CRMs, marketing automation platforms, data warehouses, ad platforms, and other go-to-market tools; named destinations include Salesforce, Marketo, HubSpot, Eloqua, Snowflake, and BigQuery. Leadspace is available through web, API, and extension access, with real-time profiles, identity resolution, audience activation, and data ingestion.

Leadspace states compliance coverage for GDPR, CCPA, and SOC 2 Type II. Starter is free and includes one seat, 25 credits per day, and 100 exports per month.
