What Leadium does
Leadium is a U.S.-based boutique B2B sales outsourcing agency founded in 2016 and headquartered in Las Vegas, Nevada. The company provides outsourced sales development representative (SDR) services including appointment setting, channel-optimized data sourcing, inbound lead qualification, and multi-channel outbound engagement spanning email, cold calling, LinkedIn prospecting, gifting, and marketing events. Delivery is performed by 100% U.S.-based teams under founder-led management, with the company explicitly contrasting itself against offshore "factory" agencies.
The technology stack is assembled from third-party enterprise sales and productivity tools including Apollo for sales engagement and data enrichment, LinkedIn for social prospecting, Zapier for workflow automation, Vidu for video outreach, and Calendly for consultation booking. Leadium layers AI-powered intent data, predictive lead scoring, and email deliverability management (SPF/DKIM/DMARC and domain reputation) on top of this stack to prioritize prospects and compress response times. Proprietary elements are limited to operational playbooks (channel-optimized contact data, speed-to-lead under 5 minutes, human-sourced validation) rather than owned models or platforms.
Go-to-market is sales-led and consultative, targeting CEOs, founders, CROs, sales executives, and marketing executives across startups, SMBs, mid-market, enterprise, public companies, and global organizations. Pricing is subscription-based on monthly programs ranging from $2,500 to above $10,000, with tiered budgets published directly on the website ($2,500-$3,500 entry, $3,500-$5,000 and $5,000-$7,000 growth tiers, $7,000-$10,000 enterprise, and custom above $10,000). The company states it has served 500+ sales organizations and counts five NASDAQ-listed client IPOs (Phunware, Freshworks, Mitek, Isoplexis, Paysafe) and 97 client acquisitions among its outcomes. Revenue is not disclosed and no external funding rounds are reported; Leadium operates as a privately-held, founder-led firm under CEO Kevin Warner.
