InsideView was acquired by Demandbase in May 2021. Its data capabilities — firmographics, contacts, technographics, and news signals — were integrated into the Demandbase Data Cloud and Sales Intelligence Cloud. Existing InsideView customers were migrated to the Demandbase platform, and new customers access InsideView's data as part of the Demandbase One suite.
InsideView offers native CRM integrations with Salesforce, Microsoft Dynamics 365, SAP Sales Cloud (Hybris), Oracle CRM, SugarCRM, and NetSuite. It also integrates with marketing automation platforms including Marketo.

InsideView was the standalone sales intelligence and data enrichment product. Demandbase One is the full ABM platform that now incorporates InsideView's data capabilities alongside advertising, website personalization, and engagement tools. Most buyers today access InsideView's functionality as part of Demandbase One rather than as a standalone product.
InsideView does not currently offer a Claude plugin, skill, or MCP integration.
