KickFire (VisiStat, Inc. doing business as KickFire) is a Silicon Valley-based provider of first-party intent data and IP address intelligence for B2B sales and marketing teams. Founded in 2005, the company built a proprietary IP-to-company identification technology called TWIN Caching® that systematically analyzes and maps hundreds of undecillion IP addresses to accurate company firmographics such as industry, revenue, employee count, and location.citeturn15search4turn15search6turn22search7
Originally known for the VisiStat web analytics product line, the business rebranded to KickFire in 2016 to align its corporate identity around IP address intelligence and account identification.citeturn14search1 Over time KickFire released a suite of offerings including LIVE Leads (account-level website visitor identification), KickFire SPARK (free watchlist-based intent alerts), KickFire for Google and Adobe (analytics integrations), Prospector (a Chrome-based sales prospecting tool), and a family of premium and free APIs for IP-to-company, domain-to-IP, IP geolocation, and data enrichment.citeturn0search3turn21search9turn10search1turn2search8
In September 2021, IDG Communications (now Foundry) acquired KickFire and integrated its first-party intent data into the broader Foundry Intent product, which combines KickFire’s IP-based signals with other sources such as LeadSift and Foundry’s own media and event properties.citeturn12search1turn12search3turn12search4 The KickFire brand continues to be used for the IP intelligence and API layer and for SPARK, while account-level intent and activation at scale are positioned under the Foundry Intent banner on G2 and in the market.citeturn7view0turn1search9turn10search0
As of mid-2025 the legacy LIVE Leads platform has been formally discontinued, with customers encouraged to work with Foundry support to migrate their tracking tags and data workflows.citeturn21search1 KickFire’s IP intelligence nonetheless remains a core component of Foundry’s martech stack and is embedded in partner platforms such as RollWorks and G2 for enhanced account identification and first-party intent enrichment.citeturn1search1turn1search8turn1search6
