Intentsify is a B2B intent-data and signal-based go-to-market company founded in late 2018 and headquartered in Westwood, Massachusetts (earlier records list Franklin, MA). It was co-founded by Marc Laplante — who serves as Co-Founder, CEO and Chairman — alongside Mike Kelly, Ed Laplante and Eric Belcher. Laplante and Kelly previously spent more than a decade at TechTarget and went on to co-found the predictive-analytics pioneer Prelytix (sold to MRP in 2015) before launching Intentsify. The company grew quickly, reaching profitability in its first full year, multiplying revenue in subsequent years, and earning back-to-back spots on the Inc. 5000. In 2021 it took growth investment from BV Investment Partners, and it has since made acquisitions — the 5×5 Data Co-Op in 2024 and Salutary Data in 2026 — to strengthen its identity graph and contact data. In early 2025, Intentsify was named a Leader in The Forrester Wave™: B2B Intent Data Providers, Q1 2025, earning the highest score for Current Offering.
At the core of Intentsify’s offering is buyer-intent data built on one of the industry’s largest and most diverse identity graphs. Rather than monitoring generic, equally weighted topics, its proprietary AI — powered by natural language processing and large language models — analyzes each customer’s websites, PDFs and value propositions to automatically select and weight the keywords and topics most relevant to their specific solutions, producing “solution-level” intent. Intentsify was also first to market with Buying Group Intent, resolving signals not just at the account level but at the buying-group and persona level to get closer to real decision-makers. Its data solutions span Buyer Intelligence (Orbit), Buying Group Intent, B2B Audiences, and Website Visitor Resolution, complemented by company and contact intelligence from its 5×5 and Salutary Data brands.
Intentsify positions itself as an “anti-platform,” designed to deliver intelligence into the systems teams already use — CRM, MAP, CDP and DSP — through custom-built integrations rather than requiring another login. Beyond raw data, it runs fully managed activation programs: intent-activated digital advertising across display and native, online video, audio, connected TV (CTV) and digital-out-of-home (DOOH); lead generation via content syndication, enhanced content syndication and tele-verified BANT; plus email and event marketing. B2B audiences are available both syndicated (pre-built for a DSP) and custom (AI-calibrated), and the company emphasizes a security and privacy program aligned with standards such as GDPR, PCI DSS and ISO/IEC 27001. Intentsify serves B2B marketing, sales and agency teams — with customers including Splunk and Sysdig citing gains in pipeline, deal size and qualified leads. Note: employee counts, revenue figures and exact certification status vary across third-party sources and should be confirmed directly with Intentsify before publication.
