Leadium

Leadium is a US-based B2B outbound sales development agency. We build and run multi-channel outbound programs for companies that need qualified pipeline without the cost and complexity of building an in-house SDR team. Our work covers the full outbound stack: cold email, cold calling, and LinkedIn prospecting. Every client engagement starts with ICP definition, hand-researched prospect lists, and customized messaging sequences designed to book qualified meetings with real decision-makers. We work across B2B verticals including technology, SaaS, AI infrastructure, financial services, professional services, healthcare, logistics, and recruiting. What makes Leadium different is the model. We operate as an intentionally boutique agency, maintaining a focused portfolio of 30 to 35 active clients at any given time. That cap is deliberate. It means every account gets senior-level strategy and hands-on execution, not a templated playbook handed to whoever is available. Our team is 100% US-based. Every SDR who works a campaign is trained in-house, managed directly, and held to clear performance benchmarks. No offshore execution. No subcontractors. Real human outreach representing our clients' brands the right way. Leadium was founded by Kevin Warner, who has spent over a decade building sales development infrastructure for B2B companies across industries. He is directly involved in campaign strategy and client delivery on every account. You always know who is running your program. We are a certified LGBTQ-owned business, holding NGLCC LGBTBE certification through the National LGBT Chamber of Commerce. Enterprise buyers with active supplier diversity programs will find us pre-qualified and ready to engage. We measure success by one thing: revenue impact. Not activity metrics, not vanity data. Qualified pipeline that moves.
