About Leadium
Leadium is an outbound sales development agency founded in 2015 by Kevin Warner and Sergey Olexa, who started CIENCE before it. It is headquartered in Las Vegas, Nevada, and says its SDR team is 100% US-based; it sold its international operations in 2022 to focus on a US team. Leadium runs appointment setting with a dedicated SDR working email, cold calling and LinkedIn against one agreed ICP, plus gifting (including SMS, video and direct mail), data sourcing and inbound lead qualification. All of its contracts are month to month, and appointment setting typically launches in 7 to 10 days. Its pricing page routes buyers to a consultation, while its blog cites $3,500 per month for cold calling and $4,000 to $5,000 per month for multichannel programs. Leadium says it has served more than 1,500 sales teams and caps itself at 30 to 35 active clients. It is a strong fit for teams that want US-based reps across several channels without a long-term contract.
Why teams look for a Leadium alternative
- Depth for complex sales. Leadium runs email, calling and LinkedIn inside one SDR program. Some teams sell complex, expensive software and need senior specialists, a real strategy and coverage across the buying committee.
- A specialist on each channel. Some teams want separate people for strategy, data, calling, email and LinkedIn, rather than one SDR covering every channel.
- Lower-cost or offshore seats. Leadium's SDR team is fully US-based. Teams on a tighter budget sometimes want offshore seats at a lower monthly rate.
- More channels. Some teams want WhatsApp, paid ads, events or account-based marketing run by the same agency as their outbound.

How to choose
First decide how complex your sale is, whether you want a specialist on each channel, and whether your reps must be US-based. SalesHive's core team is US-based, CIENCE offers US, Europe and offshore seats, Martal works onshore across several regions, and Belkins covers the most channels. Compare published pricing where it exists and get quotes where it doesn't. Then check the terms: month to month, a pilot, or a set term with exit gates. Before you sign, ask each agency who keeps the lists, scripts and call recordings when the engagement ends.
