Belkins vs Leadium: The Quick Answer

Belkins is best if you want a full-service agency handling your entire B2B prospecting and outbound strategy across any industry, and you're comfortable with month-to-month retainers. Leadium works better if you prefer a platform-first approach focused on email and LinkedIn outreach with some phone support, or if you want more control over your campaigns. Both lock you into retainer commitments. Neither guarantees you only pay for meetings booked.

What Does Belkins Do?

Belkins is a B2B lead generation and appointment setting agency founded in 2015. They run the entire outbound operation for you: research, lead list building, email campaigns, LinkedIn outreach, phone calls, and calendar management. Their SDR teams work in waves, starting with research and segmentation, then moving prospects through a multi-touch email and phone sequence.

The value prop is simple: hand off your ICP, your messaging, and your calendar. Belkins handles discovery, list building, outreach sequencing, and follow-up. They work across industries—fintech, insurance, SaaS, healthcare, real estate—so they're comfortable with generalist ICP definitions.

Most Belkins engagements include:

Lead research and list building

Email and LinkedIn outreach sequencing

Phone prospecting and cold calling

Calendar sync and meeting booking

Weekly or bi-weekly reporting and optimization

They operate on a retainer model, typically requiring 3-6 month minimum commitments.

What Does Leadium Do?

Leadium is a B2B outbound prospecting platform and agency hybrid. They provide both software and a managed service component. The core offering is email-first outreach: you upload your ICP, Leadium's platform sequences multi-touch email campaigns, LinkedIn automation, and task management to SDRs.

Leadium's angle is control plus service. You see the campaigns in real-time, manage the platform yourself if you want, or let their team run it. Phone outreach exists but is not their primary strength. Most Leadium campaigns are email, LinkedIn, and follow-up calls from prospects who engage.

Typical Leadium engagements include:

Platform access and campaign building

Lead list enrichment and validation

Email and LinkedIn sequencing automation

Task routing to their SDR team

Monthly performance reporting

Like Belkins, Leadium operates on retainer commitments, usually month-to-month but with volume minimums ($2K-$10K+ per month depending on scale).

Pricing Compared

How much does Belkins cost?

Belkins uses a monthly retainer model. Cost depends on volume (number of leads touched per month), number of campaigns, and campaign complexity. Based on public information, retainers typically range from $2,500 to $15,000+ per month, with longer commitments (3-6 months) usually getting better rates.

Some engagements charge per meeting booked on top of the retainer, which shifts risk slightly onto Belkins but still isn't outcome-based pricing. Most don't include a per-meeting fee; you're paying for activity (emails sent, calls made, meetings attempted) regardless of quality or conversion.

You'll pay whether you book 0 meetings or 10 meetings that month.

How much does Leadium cost?

Leadium's pricing is similarly retainer-based, ranging from $2,000 to $10,000+ per month depending on list size, number of campaigns, and whether you use the platform solo or request their managed team to run campaigns for you.

If you add a managed service component (their SDRs handling calls and follow-ups), costs increase. Leadium also charges for list enrichment (email verification, contact data, etc.), which adds up quickly with large lists.

Like Belkins, you're locked into a minimum monthly spend. If your campaigns underperform or you don't book meetings, you still pay the retainer.

Which Should You Choose?

Choose Belkins if...

You want a full-service agency to own the entire outbound process end-to-end.

Your ICP spans multiple industries and you need generalist research and messaging.

You prefer minimal involvement after the initial strategy call.

You have budget for a 3-6 month minimum retainer ($7,500-$90,000+ total commitment).

You're comfortable with activity-based pricing (paying for emails and calls sent, not meetings booked).

Choose Leadium if...

You prefer a platform-first, email-heavy approach to prospecting.

You want visibility into campaigns and the ability to adjust messaging or targeting on the fly.

Your ICP is heavily concentrated on email and LinkedIn engagement (fewer phone-focused verticals).

You want more control but less hands-on involvement than building an internal SDR team.

You prefer month-to-month commitments over longer retainer locks.

The Third Option Nobody Mentions

Both Belkins and Leadium operate on the same fundamental business model: monthly retainers for activity, not outcomes. You're paying for effort (emails sent, calls made, sequences run) regardless of whether those efforts actually generate qualified meetings or pipeline.

There's a better way, especially if you're in fintech, insurtech, or B2B SaaS with a specific, defensible ICP.

Nurturance offers a pay-per-meeting model on the Glencoco marketplace. You only pay when your SDRs book a qualified meeting with a prospect who matches your ICP. No retainers. No activity-based fees. No paying for failures.

Here's what you get instead:

Human SDRs doing real cold calling, not email-first sequences. Phone outreach converts higher in fintech and B2B SaaS than email alone.

Full transparency: recorded call clips and transcripts so you verify what was actually said and who you're really meeting.

Fractional CRO management included: strategy, messaging, ICP refinement, call quality coaching. Not a separate cost.

No software bloat: just outcomes. Meetings booked. Pipeline generated. Revenue closed.

Industry expertise: Nurturance specializes in fintech, insurtech, and B2B SaaS verticals. Your SDRs understand your buyer, your compliance landscape, and your sales cycle.

If Belkins or Leadium book 5 meetings from 1,000 touches and half don't convert, you still paid the full retainer. With Nurturance, you pay only for the 5 meetings that actually happened. At volume, that's typically 60-70% cheaper than traditional retainer agencies.

The trade: you need a clear, specific ICP. Nurturance is built for founders and operators who know exactly who they're selling to. If your ICP is "VP of Sales at any B2B SaaS company," Belkins' generalist approach works fine. If it's "VP of Engineering at fintech platforms processing >$10M/year," Nurturance aligns your incentives with outcomes.

The Bottom Line

Belkins and Leadium are both reputable services with solid track records. Belkins leans on full-service SDR teams and owns the entire motion; Leadium balances platform automation with managed service support. Both deliver meetings. Both charge retainers regardless of quality or fit.

The question isn't Belkins vs Leadium. It's whether you want to keep paying agencies for activity, or switch to paying for outcomes.

If you're in fintech, insurtech, or B2B SaaS and tired of retainer waste, Nurturance's pay-per-meeting model flips the incentive structure. You get real cold calling from SDRs who specialize in your vertical, full call transparency, and fractional strategy support. You pay only for meetings that book.
