What is SalesIntel?

SalesIntel unifies signal detection, account qualification, and multi-channel activation on one platform. Signal360 monitors predictive signals (funding, leadership changes, tech adoption) and demand-capture signals (website visits, pricing page views, competitor searches) across the complete buying journey. The platform automatically identifies all buying committee members and uses GTMCanvas to build signal-triggered automated workflows, aligning Marketing, Sales, and RevOps around the same intelligence.

Core Capabilities

Marketing and Sales teams need to align around the same account intelligence.

Consider alternatives: You only need a basic contact database without signal-driven workflows, have a small team with limited budget, already have mature signal detection and activation tools that integrate well, or your sales cycles are extremely short and don't benefit from predictive signals.
