Quick answer
Belkins sells monthly retainer packages sized by the number of appointments you want a year (30+, 100+ or 200+, plus a custom Enterprise plan) and shows no prices, so you get a number after a call. CIENCE publishes its price: $2,000 a month for a campaign team and $499 a month for the graph8 platform, then each SDR from $1,750 (offshore), $2,500 (Europe) or $4,500 (US) a month, a bonus when an SDR hits target and a setup fee quoted on the call. CIENCE is month to month. Belkins publishes no term. Pick Belkins if you sell into the US and want one team running a wide multichannel program. Pick CIENCE if you want to model the cost before a call, need SDRs in Europe or want to add and drop seats each month. Checked on both sites on 14 October 2026.
Belkins vs CIENCE at a glance
I'm a GTM consultant in Riga with 2000+ meetings booked for B2B clients, so I read agency proposals like these from the buyer's side of the table. Every agency fact below comes from belkins.io and cience.com.
Disclosure. I work with teams as a fractional Head of GTM or set up the outbound function inside their team, and my agency, Shipyard GTM, sells done-for-you outbound on email and LinkedIn. That puts me in competition with both Belkins and CIENCE, so weigh my take with that in mind. Neither agency, and no tool named here, pays me.

Price: appointment packages vs a line-by-line list
Belkins' pricing page offers monthly retainer packages, "custom-built" for each client. It names four and puts no figure on any of them:
| Belkins package | Appointments a year | Roughly a month | Note |
|---|---|---|---|
| For small business | 30+ | 2 to 3 | "Delivered through partnering agencies from the Belkins ecosystem" |
| Growth | 100+ | About 8 | |
| Growth Plus | 200+ | About 17 | |
| Enterprise | Not stated | Not stated | Custom SLAs and contract terms |
Every package includes a sales audit, a total addressable market calculation, manual lead research, copywriting, scheduling with no-show recovery and reports, plus tools worth "up to $10,000 annually", among them Belkins' own deliverability platform, Folderly. One catch: the small business package is run by partner agencies, not by Belkins' own team. If that's the one you're quoted, ask who will run your campaign.
CIENCE lists every line except setup:
| CIENCE line | Price |
|---|---|
| Campaign team | $2,000 a month |
| graph8 platform (contact data, email, calls, workflows, 75,000 credits a month) | $499 a month |
| SDR, offshore / Europe / US | From $1,750 / $2,500 / $4,500 a month each |
| Bonus per SDR | None below 60% of target; base × % of target × 0.35 from 60% to 99%; base × % of target × 0.7 from 100% |
| Setup | One time, quoted on the call |
With the fixed fees included and before setup, one SDR comes to $4,249 a month offshore, $4,999 in Europe and $6,999 in the US. In a month at exactly 100% of target, that's $5,474, $6,749 and $10,149. I read "base" as the SDR's monthly fee, so confirm that on the call. I go through the bonus and a three-month cost model in CIENCE pricing: SDRs by the seat vs a bundled retainer. CIENCE repriced in 2026, so older CIENCE figures you find elsewhere are out of date.
How to compare the two quotes
The two prices buy different units. Belkins sells a volume of appointments a year. CIENCE sells SDR months, each with a target for held meetings. So ask Belkins for the monthly price of the package it recommends and ask CIENCE for the target it would set per SDR. Then divide the total for the first three months, setup included, by the held meetings each plans for that period. Both say they launch within two weeks, so month one is mostly setup.
Who does the work
Belkins puts a dedicated team on each client, picked "to act as an extension of your own". That team covers research, copy, outreach and scheduling. Its homepage says it launches in 14 days, while its FAQ says 5 business days from kick-off.
CIENCE splits the work in two. A campaign team runs the campaigns, reviews the SDRs' work and reports held meetings each month. The SDRs call, email and message your buyers on LinkedIn every working day, inside graph8's software. Setup covers a verified target list, four campaigns and the email, phone and LinkedIn infrastructure, live in 14 days.
CIENCE also changed hands. Its About page says "graph8 acquired the assets of CIENCE". In practice your outbound runs on graph8, so ask what you can export if you stop.
Channels and markets
Belkins sells the wider menu. Its pricing page lists cold email, LinkedIn, intent-based cold calling, cold calls and voicemails, Messenger and WhatsApp, account-based marketing, paid ads, executive dinners, conference activation and webinar support. It doesn't spell out in text which package includes which, so ask. CIENCE keeps to three: its SDRs work phone, email and LinkedIn.
Both put the phone in the mix. If your buyers don't pick up, ask how much of the work goes into calls. For the record, I run email and LinkedIn as one sequence and don't do phone outreach, so on calling both offer something I don't.
Markets are where they split:
- Belkins calls itself "the top-rated B2B lead generation company in the USA" and publishes no list of other markets or languages.
- CIENCE prices European SDRs separately and says it works through "an international network of SDR and GTM operators across more than 10 languages".
For buyers in Europe who speak another language, CIENCE is the only one of the two that claims to cover them. For agencies built around Europe, see Belkins alternatives.
Contracts, guarantees and what you keep
Term. CIENCE's page says "Month to month, no long contract", and you can add or remove SDRs each month. Belkins publishes no minimum term or notice period, and its Enterprise plan comes with "custom SLAs and contract terms". Get the term, notice and any auto-renewal in writing.
Guarantees. The description Belkins gives search engines says its approach "guarantees 100-400 yearly appointments". Its own FAQ is more careful. Asked "Can you guarantee the number of appointments you set?", it answers with an average, around 5 to 10 appointments per 500 leads, and says that if a campaign falls short it will change the approach or the channel. It mentions no credit or refund, so ask what happens, in writing, if a quarter comes in below plan. CIENCE works the other way round: no guarantee, and you pay a bonus when an SDR hits target, so a good month costs more.
What you keep. Neither says on its site who owns the sending domains, mailboxes and lead lists if you stop. Belkins runs its own tools inside the retainer, and CIENCE's setup includes email infrastructure "with domains protected", but neither says whose name the domains sit in. Here's why that question matters.
Get it in writing. The notice period, what counts as a held meeting, what happens below plan and who owns the domains and lists when you leave. With Belkins, add who runs the work. With CIENCE, add who sets each SDR's target.
Track record: a long review trail vs a new owner
Belkins has one of the largest public review trails among outbound agencies. Clutch's own summary of those reviews names one negative theme: "Challenges with Meeting Promised Deliverables". It comes from a minority of reviewers, but it's the risk that matters on a retainer, so pin down the guarantee question above.
CIENCE has a long review history too, but much of it was written before graph8 bought the assets. Ask for a reference who signed after the acquisition.
Pick Belkins or CIENCE
Pick Belkins if you sell into the US, you want one team to run a multichannel program that can include calls, ads and events, you'd rather buy a volume of appointments than manage SDR seats and you're fine getting the price after a call.
Pick CIENCE if you want to model the cost before any call, your buyers are in Europe or speak another language, you want to add or drop SDRs month to month and you're happy for your outbound to run on graph8.
Look past both if your offer and target market haven't been tested yet, or if your buyers don't take cold calls and email plus LinkedIn would cover your market. For the wider field, see 12 Belkins alternatives, and for the other Belkins head-to-head, Belkins vs Martal Group.
What to ask both before you sign
Send both the same note before the second call, so the quotes come back in the same shape:
Hi [Name], before our next call, could you send me a few things in writing? The total for the first three months including setup, the number of held meetings you plan for months two and three, what counts as a held meeting, the minimum term and notice period and who owns the domains, mailboxes and lead lists if we stop.
Then ask two things on the call: who runs your account day to day and where they're based, and whether you can speak to a client in your segment from the last 12 months. From CIENCE, ask for one who signed after graph8 bought the assets.
