TL;DR
Belkins = multichannel outreach powerhouse, global scale, SDR stack with polish.
CIENCE = data-first, research-heavy, SDR + sales tech hybrid.
If you want brand polish and enterprise breadth, Belkins is a safe bet.
If you want aggressive, data-backed outreach with research muscle, CIENCE fits better.
But if you want pure cold calling speed, transparency, and human reps who convert? There’s a sharper alternative — RemoteAides.
Why This Comparison Matters
Let’s skip the polite sales-speak: building a cold calling function in-house is exhausting.
You burn months recruiting SDRs, training them, burning through lists, and hoping they last long enough to book a meaningful number of meetings. By the time you realize the SDR you hired isn’t hitting quota, you’ve lost a quarter of your year.
That’s why more B2B founders are outsourcing outbound not because they want to hand off sales entirely, but because they want motion without the headache.
In this space, Belkins and CIENCE are two of the most talked-about agencies. Both are trusted by hundreds of companies, both claim to fill your pipeline, and both have case studies that look great on paper.
But if you dig deeper, they represent two very different approaches to outbound.
Belkins: Multichannel Outbound with Enterprise Polish
Belkins has built its brand on being a full-service lead generation partner. They make calls and orchestrate an outbound engine across email, LinkedIn, cold calling, list building, and appointment setting.
They’ve worked with 1,000+ companies, especially in tech, SaaS, and professional services. If your goal is to run a polished, multi-touch campaign that reaches prospects on multiple fronts, Belkins has the infrastructure.
One of their differentiators is Folderly, their in-house email deliverability tool, which helps keep outreach out of spam folders a common pain point for teams relying on email.
Their account managers work closely with clients to align messaging, adjust targeting, and keep the campaign machine running. This makes Belkins feel more like a marketing department extension than just a vendor.
But here’s the trade-off: because Belkins spreads its focus across channels, cold calling is one piece of the puzzle, not the centerpiece. If phone-first outreach is your top priority, you may find that calls are part of a broader, slower-moving play rather than a standalone driver of meetings.
Why companies choose Belkins over CIENCE:
Full-stack outbound engine with multiple touchpoints.
Enterprise-grade process and reporting.
In-house tech like Folderly to improve deliverability.
Strong for brand-conscious companies who value campaign breadth over call volume.
CIENCE: Data-Driven, Research-Heavy Outbound
CIENCE approaches outbound like a science experiment and every campaign is powered by heavy data research and process control.
They run a People-as-a-Service model, pairing SDRs with data researchers, sales operations staff, and campaign managers. This means you’re not just hiring callers but also a small team to find, qualify, and engage your market.
Their strength is in list accuracy and targeting depth. They put a lot of effort into building high-quality databases before outreach even begins. If your audience is hard to find especially niche industries or senior decision-makers, this research-first approach reduces wasted dials.
On the delivery side, CIENCE also runs multichannel campaigns that blend calls, emails, and LinkedIn. The difference is that every move is backed by fresh, customized prospect data.
The downside? This process can take longer to spin up. You may spend weeks in the research and list-building phase before the first call is even made. For teams that need pipeline fast, this can feel slow even if the long-term targeting is strong.
Why companies choose CIENCE over Belkins:
Unmatched focus on data accuracy and lead research.
Strong for niche targeting and hard-to-reach audiences.
Integrated teams handling multiple outbound functions.
Campaigns rooted in custom-built prospect lists, not generic databases.
Head-to-Head: Belkins vs CIENCE in the Real World
While both agencies deliver multichannel outbound, the philosophy is where they diverge.
Belkins operates like a well-oiled marketing engine polished, scalable, and process-driven. They’re ideal if you want your brand represented across multiple channels with an enterprise touch.
CIENCE works like a research lab digging deep into your market before making a move, then running highly targeted, data-backed campaigns. They’re ideal if precision targeting is more valuable to you than speed to first call.
If we’re talking pure cold calling firepower, both can deliver calls but neither is built solely around the phone. In both models, cold calling is a support act in a larger multichannel show.
That’s why many founders who want phone-first momentum end up looking for alternatives.
Cold Calling vs Multichannel in 2025
Multichannel sounds like the safer bet, more channels, more chances, right?
In reality, it’s easy for multichannel campaigns to drift into email-heavy sequences with calls playing second fiddle. And when calls are an afterthought, they lose the urgency and human connection that make them powerful.
Cold calling, done right, is not just another channel. It’s the fastest feedback loop in sales. It lets you hear objections in real-time, adjust your pitch instantly, and build rapport in a way an email never will.
The problem is, few agencies in 2025 are truly phone-first anymore. That’s where alternatives like RemoteAides stand out.
A Sharper Alternative: RemoteAides
While Belkins and CIENCE operate in the multichannel space, RemoteAides is unapologetically phone-first.
They skip the bloated tech stacks and focus entirely on voice-led outbound. No diluted efforts across half a dozen channels, just reps who dial, handle objections, and book meetings.
Their team is made up of experienced African-based cold callers with strong sales instincts, fluent English, and cultural adaptability. Every rep is matched to your ICP, not just whoever’s available.
The biggest difference? Speed. RemoteAides onboards campaigns in days, not weeks. You can be listening to real cold calls before a multichannel agency has even finalized your prospect list.
Pricing is transparent, starting at €800/month per rep, with no hidden fees or long-term lock-ins. For founders who want lean, accountable outbound that actually moves the pipeline, that’s hard to beat.
What to Look for in a Cold Calling Agency
Whether you’re leaning toward Belkins, CIENCE, or a phone-first agency like RemoteAides, a few things matter more than any case study:
Reps who can sell, not just read scripts.
ICP alignment so conversations resonate.
Fast feedback loops with real call recordings.
Transparent pricing so you know exactly what you’re paying for.
Cultural fit so they sound like your team, not a vendor.
