What Leadspace does
Leadspace is a B2B customer data and GTM intelligence company, founded in 2007 and headquartered in Palo Alto with an additional New York office. The company operates the Leadspace GTM Data Intelligence Cloud, an enterprise platform that unifies buyer, account, and signal data into a continuously updated intelligence layer powering CRM, MAP, and data warehouse workflows. The underlying data asset is an 800M+ buyer identity graph with 100+ technology categories and 10B+ weekly buying signals; named data graph users include Microsoft, Nvidia, and Salesforce.
The platform is composed of four modular solutions — Dynamic Data Intelligence, Inbound Marketing Intelligence, Outbound Prospecting Intelligence, and Buying Team Intelligence — that collectively address ICP fit scoring, sub-90-second lead-to-account matching, buying committee mapping, territory planning, and real-time enrichment. In 2025, Leadspace launched Sidekick, a free Chrome extension that surfaces the same identity graph on LinkedIn for verified emails, direct dials, AI fit scoring, and CRM push, explicitly priced 2.5-10x below ZoomInfo and Apollo.
The business model combines enterprise subscription contracts (typically exceeding $100K annually) with a freemium Sidekick tier spanning a free plan, $49/user/month Solo, $89/user/month Pro, and a custom enterprise tier. Go-to-market is hybrid: enterprise field sales for the core platform, self-serve PLG for Sidekick, and channel partnerships (notably a November 2025 StackAdapt ABM integration). Customers span SaaS, cloud communications, fintech, tax compliance, martech, and sales services, with documented case-study outcomes ranging from 20% to 87% conversion improvements.
