```html Belkins vs CIENCE - Arvani Media

If you're evaluating Belkins vs CIENCE for B2B lead generation in 2026, the short answer is: Belkins wins on track record and review volume, while CIENCE wins on flexibility and built-in data technology. Both are legitimate agencies, but they serve different types of buyers — and picking the wrong one can burn serious budget without moving your pipeline. This breakdown covers pricing, services, reviews, and the real differences so you can make the right call fast.

What Belkins and CIENCE Actually Do

Belkins is a done-for-you B2B lead generation and appointment setting agency. They're best known for cold email outreach managed by a dedicated team of SDRs and copywriters, with multi-channel campaigns that combine email, phone, and LinkedIn. According to Clutch, Belkins has been ranked the #1 appointment setting company for five consecutive years and has 230+ verified client reviews on the platform. They've reported booking over 200,000 appointments across roughly 1,000 clients.

CIENCE Technologies operates as a hybrid: part outsourced SDR agency, part software company. On the services side, they run outbound and inbound SDR campaigns with a dedicated team. On the tech side, they've built graph8 — an AI-powered go-to-market platform that bundles intent data, audience intelligence, and multi-channel sequencing. That combination makes CIENCE more of a technology-forward agency than a traditional services shop, and it's what sets them apart from most pure-play lead gen agencies.

Both agencies target mid-market and growth-stage B2B companies — think SaaS, professional services, staffing, and financial services — that have a real sales team but need a consistent top-of-funnel engine they don't have to build from scratch.

Belkins vs CIENCE - What Belkins and CIENCE Actually Do

Services Comparison: Belkins vs CIENCE

At first glance, the service menus look similar. Both agencies do outbound prospecting, appointment setting, cold email, and LinkedIn. The differences show up in the depth of each channel and what's included without an add-on fee.

What Belkins Offers

Belkins covers the full outbound stack as a managed service:

Their model is highly managed — you get a dedicated team handling strategy, copywriting, sending, and reporting. For teams who want genuine hands-off execution and minimal internal involvement, this is the big appeal. It pairs well with companies already running a B2B outbound system that needs supplemental execution bandwidth, or those just starting to build outbound from scratch.

One thing to note: Belkins doesn't have a proprietary data platform. Their lead research is done manually, which maintains quality but means you're not getting real-time intent signals or AI-powered audience segmentation out of the box. If you're curious how they build B2B lead lists, it's a structured manual process rather than a data-tool-driven one.

What CIENCE Offers

CIENCE's service list overlaps significantly but adds a few meaningful layers:

The built-in data layer is the biggest differentiator. According to graph8.com, the platform includes 700M+ contacts, 100M+ companies, and 30 billion intent signals trained on a decade of real CIENCE campaign outcomes. That means CIENCE clients can build highly targeted lists without paying separately for a data subscription — the intent signals are baked in.

For teams running email and LinkedIn multi-channel outreach, CIENCE's orchestration layer can manage sequencing across both channels automatically. They also have built-in AI reply classification as part of their automation stack — something that matters a lot when campaigns are running at scale and you need to route hot replies without manual triage.

Pricing and Contract Terms

Pricing is where Belkins and CIENCE diverge most noticeably — not just in numbers, but in how they structure the relationship.

Belkins Pricing

Belkins uses a retainer model. Based on third-party reviews on OutboundSalesPro and LeadHaste, engagements typically start around $5,000–$5,500/month, scaling up based on channels used, market complexity, and team size. Multi-month commitments of 3–6 months are standard. There's no month-to-month option. Custom quotes are required for exact numbers.

CIENCE Pricing

CIENCE's model is more modular. Per their published comparison pages, the GTM setup starts at $5,000 as a one-time fee, with ongoing campaign management from $2,499/month. Their Talent Cloud model offers direct SDR hiring at cost, removing the agency markup — a meaningful distinction for companies building longer-term outsourced teams. The graph8 platform is separately priced at $499/month per graph8.com. Month-to-month contracts are available through certain arrangements.

The Broader Cost Context

Both options look expensive until you compare them to building in-house. According to cost analysis published by Konsyg, a fully loaded in-house SDR costs approximately $140,000/year once you add salary, benefits, tools, management overhead, and recruiting costs. SDR annual turnover sits between 35–45%, meaning that cost recurs frequently. HubSpot data puts new sales hire ramp time at an average of 3.2 months — so you're paying full cost while output is partial.

Track Record, Reviews, and Results

Review volume and consistency matter when you're handing over budget and pipeline access to an outside team. Here's where each agency stands based on publicly verified data.

Belkins Review Data

Clutch reviews for Belkins frequently highlight consistent month-over-month delivery, improved reply rates, and high-quality lead targeting. Specific reviews reference outcomes like 137 qualified demo bookings and 57 qualified sales appointments within a single engagement. The review base is the largest of any outbound agency on Clutch — that depth is hard to fake.

CIENCE Review Data

CIENCE's G2 popularity ranking is notable — being the #1 most popular lead gen service on G2 means high search visibility and buyer consideration volume. That said, their Clutch review base is smaller than Belkins, and recent reviews include more mixed feedback around SDR turnover and lead quality consistency. That doesn't make CIENCE a bad choice, but it's worth asking for recent client references and performance data before signing.

One factor both agencies share: deliverability matters as much as the strategy. No matter who's running your campaigns, if your infrastructure isn't set up correctly, results suffer. See our guide on cold email deliverability for the fundamentals that every outbound campaign depends on, and what to watch for if you start seeing inbox issues — including a rundown on cold email spam fixes when things go sideways.

Which Agency Should You Actually Pick?

Pick Belkins if: you want the safest bet on a fully managed service with the longest proven track record. Their Clutch ranking and review volume are hard to argue with. The model is genuinely hands-off — you show up to the meetings they book. If you're running cold email in a competitive B2B niche and need proven execution without building internal infrastructure, Belkins is the right call. This is especially true if you already understand your cold email offer and buying signals — they'll amplify what's already working.

Pick CIENCE if: you want tech-forward flexibility and care about intent data, multi-channel from day one, or the ability to move month-to-month before committing long-term. The graph8 platform is a real differentiator — Belkins doesn't have an equivalent. If you're debating cold email vs. LinkedIn as your primary channel, CIENCE's orchestration layer handles both without needing separate tools or teams.

The honest reality: both agencies are solid options for B2B companies with an active sales team and a clear ICP. Where either can fall short is for early-stage companies or teams whose targeting, messaging, or offer still needs work. An agency amplifies your motion — it doesn't create it. If your fundamentals aren't dialed in, outsourcing execution before that's fixed produces frustrating results regardless of who you hire.

The B2B lead generation services market is growing fast — according to Business Research Insights, the market is valued at $3.33 billion in 2026 and growing at an 11.91% CAGR. More options and more competition means you have more choices than ever — but it also means due diligence matters more. Whether you go with Belkins, CIENCE, or a boutique agency, the criteria are the same: proven results, transparent reporting, and alignment with how your sales team actually operates.

Not Sure Which Agency Fits Your Pipeline Goals?

Arvani Media is a done-for-you B2B outbound agency specializing in cold email, LinkedIn outreach, and AI-powered personalization. Before you spend $5,000+/month with a large agency, it's worth getting a second opinion on your outbound strategy — including whether you even need a full-service agency or a leaner setup that gets you the same results.

Belkins vs CIENCE - Pricing and Contract Terms

Frequently Asked Questions

Belkins has the stronger appointment setting track record, holding the #1 spot on Clutch for five consecutive years with 230+ verified reviews. CIENCE is a solid option but its Clutch ranking has slipped from peak years and its review base is smaller. For pure appointment setting with minimal internal involvement, Belkins is the more proven choice.

Based on third-party reviews, Belkins typically starts around $5,000–$5,500/month with 3–6 month minimum contracts. CIENCE starts lower at approximately $2,499/month plus a $5,000 GTM setup fee, with more flexible month-to-month options through their Talent Cloud model. Both require custom quotes for exact pricing based on scope and channels.

Yes. CIENCE is backed by graph8, an AI-powered GTM platform with 700M+ contacts, 100M+ companies, and 30 billion intent signals. According to graph8.com, the platform is priced at $499/month and includes multi-channel sequencing and AI-driven campaign orchestration — something Belkins does not offer.

Yes — boutique B2B outbound agencies often provide tighter execution, more direct communication, and better pricing for companies that don't need enterprise-scale SDR teams. The best fit depends on your budget, ICP, and how hands-on you want to be. For companies exploring alternatives, evaluating smaller specialized agencies alongside the major players is worth the time.

Look for verified reviews on Clutch or G2 from clients in your industry, transparent reporting practices, and a clear explanation of how they build and qualify lists. Ask about deliverability infrastructure, reply handling, and what happens when results underperform. Before signing any contract, make sure your ICP and offer are defined — agencies perform best when the strategy is already solid.

Which Agency Should You Actually Pick?

Pick Belkins if: you want the safest bet on a fully managed service with the longest proven track record. Their Clutch standing and review volume are hard to argue with. The model is genuinely hands-off — you show up to the meetings they book, while their team handles everything else. This works especially well when you already know your cold email offer and have a handle on your buying signals — they'll amplify what's already working. For teams debating cold email vs. LinkedIn as a primary channel, Belkins leans heavily email-first, so keep that in mind.

Pick CIENCE if: you want tech-forward flexibility and care about intent data, multi-channel execution from day one, or the ability to operate month-to-month before committing long-term. The graph8 platform is a real differentiator — Belkins doesn't have an equivalent. If your campaigns will cover multiple channels simultaneously and you want a single platform managing the orchestration, CIENCE's stack is built for that.

The honest reality: both agencies are solid options for B2B companies with an active sales team and a defined ICP. Where either can fall short is for early-stage companies or teams whose targeting, messaging, or offer still needs work. An agency amplifies your motion — it doesn't create one from scratch. If your fundamentals aren't dialed in before you start, outsourcing execution won't fix that, regardless of who you hire.

The B2B lead generation services market is growing quickly — according to Business Research Insights, the market is valued at $3.33 billion in 2026 and growing at an 11.91% CAGR through 2035. More options means more choices, but it also means more due diligence. Whether you go with Belkins, CIENCE, or a smaller boutique agency, the criteria are the same: proven results in your specific industry, transparent reporting, and a model that fits how your sales team actually operates.
