TL;DR
- Belkins is known for its large team and multi-channel outreach (email, LinkedIn, and cold calling), making it ideal for companies that want volume and structure.
- Leadium focuses more on personalized outbound and smaller, high-touch campaigns, making it a better fit for startups or niche industries.
- Both agencies help with cold calling and lead generation, but their approach and pricing models differ.
If you want a more flexible, transparent cold calling service, I recommend RemoteAides. They offer trained SDRs, simpler pricing, and hands-on campaign support.
Before You Choose
Belkins and Leadium are two names that come up often when you’re searching for cold calling agencies that can actually deliver meetings not just calls. .
But when you look closer, their approaches (and results) are quite different. Belkins leans heavily on automation and outreach scale, while Leadium emphasizes custom research and tailored messaging. In this comparison, we’ll break down how each one works, their strengths and weak spots, and which type of business each agency fits best.
Belkins
Belkins is one of the most recognized names in outbound lead generation. Their team combines cold calling with multichannel outreach (mainly email and LinkedIn), and they promise predictable pipelines powered by intent data and automation.
The agency positions itself as a done-for-you outbound engine, so you get a dedicated team, a database of prospects, and ongoing reporting. But while that sounds ideal, their service comes with a higher price tag and mixed client feedback on lead quality.
Pros
Structured process with dedicated account managers and SDRs.
Uses intent data and automation to reach prospects at scale.
Detailed reporting and campaign visibility.
Cons
Pricing can be steep for smaller businesses.
Several reviews mention inconsistent meeting quality.
Limited flexibility — campaigns often follow a set formula.
Best for:
B2B companies that want a structured, data-backed outreach system and are comfortable paying more for volume and visibility.
Leadium
Leadium focuses on building customized outbound strategies rather than cookie-cutter campaigns. They combine human-led research with verified data to identify high-intent prospects before any calls are made. Their SDRs also handle both cold calls and follow-up sequences, giving each campaign a full outreach cycle.
Where Belkins feels more automation-driven, Leadium takes a personalized approach. However, this can make them slower to scale — and their pricing is also on the premium side for smaller teams.
Pros
Tailored outbound strategies built around your ICP and goals.
Hands-on research and data verification before campaign launch.
Integrated outreach (calls, emails, and LinkedIn) managed by one team.
Cons
Slower onboarding due to heavy customization.
Pricing may not fit early-stage startups.
Performance depends on data accuracy and campaign structure.
Best for:
Companies that value personalization, detailed data work, and a partnership-style engagement over quick volume.
How Belkins and Leadium Compare
At first glance, both Belkins and Leadium offer full-service outbound support — but their approach to cold calling, pricing, and delivery style set them apart. Here’s how they compare:
1. Approach to Cold Calling
Belkins: Cold calling is just one part of their larger appointment-setting model. They combine email outreach, LinkedIn engagement, and call follow-ups to create consistent touchpoints — but this sometimes means fewer actual calls.
Leadium: Cold calling is built into a personalized outbound framework. Every campaign starts with custom data research, ICP definition, and manual list-building, which gives their calls more context and relevance.
2. Caller Quality
Belkins: Their team is known for professional communication and structured scripts, but some clients note inconsistency in caller quality depending on the assigned SDR.
Leadium: Their SDRs tend to handle fewer clients at a time, allowing for more in-depth product knowledge and better alignment with the company’s tone.
3. Use of Technology
Belkins: Uses automation and data enrichment tools to scale outreach quickly. Great for volume — but sometimes at the cost of personalization.
Leadium: Relies on data verification tools but still prioritizes manual input and SDR-driven targeting. This hybrid approach leads to higher precision but takes more setup time.
4. Pricing
Belkins: Typically charges higher retainers due to their infrastructure, team setup, and automation tools.
Leadium: Pricing depends on project size and research depth, but it’s often more flexible and can scale with smaller teams.
5. Best Fit
Belkins: Ideal for companies that want predictable, high-volume outreach with less manual input.
Leadium: Better for businesses that value precision, verified data, and a more human-centered calling process.
