While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more

To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more

Written by the company

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 services cover the full outbound stack: cold email outreach, cold calling, and LinkedIn prospecting. Every program starts with a defined ideal customer profile, a hand-researched prospect list, and personalized messaging sequences designed to generate qualified meetings with real decision-makers. We work across B2B verticals including technology, SaaS, professional services, financial services, healthcare, logistics, and more. What separates Leadium from other outbound agencies and outsourced SDR providers is the model. We are intentionally boutique. We work with a focused portfolio of active clients at any given time so every account receives senior-level strategy and hands-on execution, not a junior account manager buried under 40 campaigns. Our founder is directly involved in campaign strategy, client delivery, and outcomes. This is not a shop where you onboard, get handed off, and wonder who's running your program. Our team is 100% US-based. Every sales development representative who touches your campaign is trained, managed, and accountable to clear performance benchmarks. No offshore teams. No automated spray-and-pray. Real human outreach, executed with precision, representing your brand the way it deserves to be represented. Leadium is a certified LGBTQ-owned business. We hold NGLCC LGBTBE certification through the National LGBT Chamber of Commerce and are recognized as a supplier diversity-eligible vendor on Clutch. Enterprise buyers and procurement teams with active supplier diversity programs will find us pre-qualified and ready to engage. We have built outbound programs for hundreds of B2B companies across the United States. Whether you're a funded startup building your first pipeline or an established company looking to add a reliable outbound channel, Leadium has operated in your stage and your vertical. If you are evaluating B2B outbound agencies, outsourced SDR companies, appointment setting services, or lead generation firms, Leadium is worth a serious conversation. We measure success by one thing: revenue impact. Visit leadium.com to learn more or schedule a consultation with our team.
