Leadium was hired by a startup accelerator company to help them build an SDR program. The team is in charge of conducting campaigns, prospect research, email content development, lead qualification, and more.

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.
