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. Its listed security measures include encrypted storage and transfer, role-based access control, multi-layer authentication, and continuous vulnerability monitoring. 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. Solo costs $49 a month and Pro $89 a month, both billed annually, with one seat each. Enterprise pricing is custom.
