Our Story

We built Leadium after seeing SDR teams judged on activity, not outcomes. Founder-led, we treat B2B lead gen & appointment setting like a craft: precise ICPs, verified data, senior US SDRs, and enterprise research. We map your TAM, run multichannel campaigns, and optimize on revenue signals. 10+ years, hundreds of programs. Trusted by Goodyear, Rackspace, HackerOne and SMBs. Once 550+ global team members, now 100% US-based. Embedded partner focused on pipeline growth, not vanity metrics.
