Best B2B Lead Generation Company: 7 Picks Compared

How we chose

The shortlist came from agencies that sell people and outcomes rather than software logins, and the deciding filter was price transparency: each entry either publishes a starting price on its own site or states its pricing model plainly enough to quote. Every price below was read from the agency's own pricing or service page and checked on 13 November 2026. No hands-on testing was done, no client results were scored, and no buyer-reported figure is presented as a vendor price. Where an agency publishes no dollar figure, the pick says so.

1. CIENCE: best for published per-SDR pricing at scale

CIENCE sells outsourced SDR teams that work across phone, email and LinkedIn, plus B2B contact data and appointment setting. Its platform, graph8, sits underneath the service. The pricing page breaks the cost into parts instead of hiding it behind a single quote: a campaign team from $2,000 a month, the graph8 platform at $499 a month, and SDRs from $1,750 a month offshore or from $3,500 a month in the US or Europe, with a performance bonus when an SDR passes 60% of target.

That itemised list is the reason CIENCE leads this ranking for buyers who want to model cost before a sales call. You can see what each extra SDR adds and what the platform costs on its own. The trade-off is that the parts add up fast. One offshore SDR with the team and platform fees comes to $4,249 a month before setup and bonus, and a US-based SDR pushes the same setup to $5,999 a month. A one-time setup fee is listed without an amount, so ask for it in writing. Billing is month to month.

Skip CIENCE if your average deal is small. The model fits companies selling high-value contracts that can absorb a multi-thousand-dollar monthly programme.

2. Belkins: best for appointment setting for mid-market teams

Belkins is a B2B appointment-setting agency founded in 2017. Its service covers cold email, LinkedIn outreach, cold and intent-based calling, account-based marketing, outsourced SDRs and deliverability consulting, and it also offers HubSpot CRM consulting. Every package includes a sales audit and strategy mapping, total addressable market calculation, buyer profile refinement, manual lead research and validation, copywriting, appointment scheduling and no-show recovery.

Belkins does not publish a single list price. Its pricing page sells packages by yearly appointment volume: a small-business package at 30+ appointments a year, Growth at 100+, Growth Plus at 200+, and an Enterprise tier with custom strategy and terms. That structure tells you what Belkins thinks it sells — a number of meetings a year — but it leaves the monthly cost to a proposal. Its most common recommended term is a 12-month subscription, with terms ranging from 3 to 12 months depending on strategy.

Skip Belkins if you need a firm number before talking to sales. It fits buyers who want a large, multichannel team and are comfortable committing for a year.

3. Callbox: best for multi-country campaigns

Callbox has run B2B lead generation since 2004 and works across North America, Asia-Pacific, Latin America and EMEA, with local teams in Singapore, Australia and New Zealand among others. Its offer covers lead generation, appointment setting, outsourced SDRs, account-based marketing, and event and webinar marketing. Each Campaign Pod includes one dedicated SDR plus a team of six, a multi-channel outreach cadence, AI-enriched and human-curated contact data, multilingual coverage, campaign manager oversight and weekly reporting. Its own CRM is included.

The pricing page gives an estimated monthly investment of $7,334 for one pod, with the exact price provided after consultation and no commitment required. That figure is an estimate, not a quote, and the range behind it is wide, so treat it as a budgeting anchor. The pod model also means you buy one market segment or persona per pod: entering three regions means three pods.

Skip Callbox if you sell in one market only. It fits companies that need the same outbound programme running in several countries at once.

4. Martal Group: best for B2B tech outsourced sales teams

Martal Group is a Canadian outsourced sales agency founded in 2009, focused on B2B technology and SaaS companies. It pairs onshore sales executives with an AI-powered SDR platform, and its tiers run from outbound lead generation alone (Tier 1A) through lead generation plus customer onboarding (Tier 2) to lead generation, onboarding and account management (Tier 3). The pricing page publishes monthly activity targets for the outbound tier: 3,000 to 5,000 prospects targeted, 9,000 to 12,000 emails sent, 250 to 450 calls, 600 to 700 LinkedIn follow-ups, 150 to 200 responses and 20 to 30 qualified leads.

Martal Group publishes structure but no dollar amounts. Tier 1A is a flat fee per month after a 3-month pilot; Tiers 2 and 3 add a sales commission after a 4-month pilot, then move to a monthly subscription. The published funnel targets are useful because they let you judge whether the volume matches your sales capacity — 20 to 30 qualified leads a month is only useful if your team can work them.

Skip Martal Group if you want to start month to month. It fits B2B tech companies whose real gap is experienced salespeople rather than an outbound system.

5. SalesRoads: best for US-based SDRs with no long contract

SalesRoads is a Florida-based appointment-setting agency founded in 2007, and every SDR is based in the United States and employed directly rather than contracted. Its programmes focus on outbound calling with personalised email layered in, plus appointment setting, lead generation and SDR outsourcing, with inbound appointment setting and account reactivation as add-ons.

The pricing page lists $11,950 per 4-week engagement for one SDR, $16,750 for two, falling to $7,192 per SDR at six. Every programme includes a client strategist, a performance coach, a research team and 500 prospect records per SDR per month, and the terms state no long-term commitment — cancel anytime. Note the billing rhythm: a year has thirteen 4-week periods, so one SDR costs $12,946 a month on a calendar-month equivalent, not $11,950. Email deliverability infrastructure is billed separately.

Skip SalesRoads if your buyers do not care where the caller sits. It fits US companies that want domestic callers and are willing to pay the premium for them.

6. Sopro: best for managed outreach with no minimum term

Sopro is a UK-based managed prospecting agency founded in 2015, with offices in Brighton, Miami and Skopje. It runs multi-channel B2B outreach — email, LinkedIn messaging, display ads, phone and physical mail — with a bespoke audience built for each client, intent tracking from website visits and a live reporting portal. Replies go to your team rather than to a separate appointment-setting queue.

Sopro's pricing page states that pricing starts at around £3,000 per month, with no minimum contract. That combination is rare in this list: most agencies in the same price band ask for a 3-month pilot or longer. The price is shaped by market coverage rather than campaign complexity, and longer commitments earn discounts. One limit to note: Sopro's strength is precision targeting and compliance, not raw meeting volume, so buyers chasing a high number of booked meetings per month should check the expected volume before signing.

Skip Sopro if you need a US-only team or a high-volume appointment engine. It fits UK and European mid-market companies that want managed outreach without locking into a term.

7. Cleverly: best for budget LinkedIn outreach

Cleverly is a done-for-you LinkedIn outreach agency. Its team runs prospecting campaigns from your LinkedIn profile — connection requests, message sequences and follow-ups — with list building, copywriting and an account manager. LinkedIn lead generation starts at $397 a month, which is the lowest published entry price in this list by a wide margin. Cold email and cold calling are sold separately: cold email is listed at $1,995 a month and cold calling lead generation at $4,000 a month for a dedicated SDR.

The low price buys one channel. LinkedIn Sales Navigator is required on top and billed to you separately, at roughly $100 a month, and reviewers report a 90-day minimum on the LinkedIn plans with a no-refund policy. Volume-based outreach on LinkedIn also needs careful targeting, because connection-request limits punish broad lists.

Skip Cleverly if you need email and phone alongside LinkedIn. It fits small businesses that want a managed LinkedIn programme at a listed price and can live with a single channel.

What one booked meeting really costs

A monthly retainer hides the unit that matters, so convert each price to a cost per qualified meeting before you compare agencies. Martal Group's own published funnel gives you the arithmetic: 20 to 30 qualified leads a month from its outbound tier. At a $5,000 monthly programme, 25 qualified leads means $200 per lead. At a $7,334 Callbox pod producing the same 25 leads, the figure is $293 per lead. At Cleverly's $397 a month, even 5 qualified leads means $79 per lead — but those leads come from one channel and a narrower service.

Run the same calculation with your own numbers: monthly programme cost divided by qualified meetings delivered, then multiply by your close rate to get cost per customer. A $5,000 programme that books 10 meetings a month at a 20% close rate costs $2,500 per customer. If your average contract is worth less than that, the agency model does not pay, whatever the headline price says.

How to choose

• You sell high-value contracts and want cost transparency first: start with CIENCE, because its itemised pricing lets you model the total before a call.
• You need meetings booked in several countries: shortlist Callbox, and budget one pod per region.
• Your buyers expect US callers: SalesRoads is the only pick built entirely on US-based SDRs, and its price reflects that.
• You sell B2B tech and need senior sellers, not just outreach: talk to Martal Group and accept the pilot term.
• Your budget is under $1,000 a month: Cleverly's LinkedIn programme is the only priced option at that level, and you should add the Sales Navigator cost to the total.
• You want managed outreach with no lock-in: Sopro's no-minimum-term model is the least committing full-service option here.

Before you sign anything, read the best lead generation software list to see whether software plus one SDR covers your need more cheaply, and the best lead intelligence software list if your real gap is data rather than people. The best email finder tools for sales teams post covers the contact-data layer most of these agencies charge for separately. When you take proposals, use the questions to ask a marketing agency guide, and if the work touches your search presence as well, Adziq's SEO services page explains how that side is scoped.

Common mistakes when hiring a lead generation company

• Comparing retainers instead of cost per meeting. A $3,000 programme that books 5 meetings costs more per meeting than a $7,000 programme that books 25.
• Forgetting the extras. Setup fees, deliverability infrastructure, Sales Navigator and per-meeting bonuses sit outside most headline prices.
• Signing before the pilot terms are clear. Ask what the pilot must deliver for the rolling contract to start, and who judges it.
• Not asking who owns the data. Prospect lists, sequences and message copy should stay yours if you cancel.
• Buying volume your sales team cannot work. Twenty-five qualified leads a month is a liability, not a win, if nobody follows up within a day.
