Best B2B lead generation agencies in 2026

How we chose and ranked these agencies

Tibexa publishes this list and is a vendor in this market, so it appears as one entry, placed by the same checks as the others. We read each agency's own website on 18 October 2026. We did not call any of them, buy from them or read their reviews, so nothing here says which agency performs best. Every number attributed to an agency is that agency's own claim.

The ranking uses five checks. Does the site say plainly what is sold? Does it publish a price, a price floor or a pricing model? Does it state contract length and how to exit? Does it say who owns the data, domains and scripts? Does it state limits or say who it is not for? Agencies that publish a price or price floor come first, then those that publish only a pricing model, then those that publish neither. Within each group the order follows how many of the other four checks the agency's own pages answer. A published price comes first because it is the one thing you cannot work out yourself.

Two agencies we meant to include are missing. Martal Group's site refused our requests with an access-denied error, and LeadBird's page, as we could load it, gave only a one-sentence description. Neither left enough to verify. Narrower lists: cold email agencies and appointment setting companies.

The ten agencies at a glance

CIENCE

Best for B2B teams that want a staffed SDR program with a per-SDR price and a month-to-month term. CIENCE sells outsourced SDR teams that book meetings by cold call and cold email, plus B2B contact data.

Its pricing page lists a $2,000 monthly campaign team fee, a $499 monthly platform fee with 75,000 credits included, and SDRs from $1,750 (offshore), $2,500 (Europe) or $3,500 (US) each per month. SDRs earn a bonus when they hit a monthly held-meeting target, and a one-time setup fee has no amount shown. The page's own example, five offshore SDRs, comes to $11,249 a month plus bonus. It says the term is month to month and a campaign goes live in under 14 days.

The homepage says to expect 5 to 20+ qualified meetings a month per SDR, depending on industry and target, and does not call that a guarantee. It also describes the performance element as a commission per held meeting, while the pricing page calls it a bonus, so ask for the formula in writing.

SalesRoads

Best for teams that want dedicated phone and email SDRs billed as a program, with the price visible up front. Its products are outbound appointment setting and market-research lead generation.

Its pricing page lists prices for each 4-week period: $11,950 for one SDR, $16,750 for two, $23,500 for three, $30,150 for four, $36,700 for five and $43,150 for six. It says there is no long-term commitment and you can cancel at any time, and that a team launches 15 business days after kickoff. Every program includes a playbook, 500 prospect records per SDR per month, CRM integration and a live dashboard.

Inbound appointment setting and account reactivation are add-ons. In the page's inclusion table, email deliverability infrastructure (multiple domains and mailboxes) carries no Included mark, so ask whether it sits inside your price. Source: SalesRoads pricing, checked 18 October 2026.

Sopro

Best for B2B companies that want managed multi-channel outreach and a stated price floor, quoted in pounds sterling. The offer covers B2B lead generation, cold email, demand generation, account-based engagement and multi-channel outreach.

Its pricing page says pricing starts at around £3,000 a month, explains that it lists no tiers because each campaign is tailored, and says there is no minimum contract. The service is described as fully managed, with a bespoke audience built fresh and a data set you can download and keep.

The homepage headline says Sopro is trusted by 3,750+ businesses, while its statistics block shows 3,375 clients, so ask for references. Source: Sopro pricing and Sopro homepage, checked 18 October 2026.

Callbox

Best for companies that want a multi-country, multi-language outbound program from a large provider. Its range runs from B2B lead generation to appointment setting, outsourced SDRs, account-based marketing, event and webinar marketing, and multilingual SDR teams for APAC, EMEA, LATAM and North America.

Its homepage publishes no prices and says pricing varies with campaign scope, target market and engagement model. A Callbox article on appointment setting pricing cites what it calls Callbox's published estimate of $16,000 to $32,000 a month per campaign pod, on a minimum one-quarter contract.

Callbox says results depend on industry, audience and message alignment, and it states no performance guarantee. Source: Callbox homepage and Callbox pricing article, checked 18 October 2026.

Belkins

Best for companies that want one vendor across several channels and a stated annual appointment range. The core product is omnichannel appointment setting (cold email, calling, voicemail, SMS and WhatsApp, LinkedIn and paid advertising), plus outsourced SDRs, deliverability consulting and HubSpot CRM consulting.

Its homepage says it delivers 100 to 400+ qualified appointments in a year, footnoted as average yearly outcomes that depend on multiple factors. Its appointment setting page shows an average starter price of "from $5,000" with 1,500 leads a month, three outreach channels and "100 guaranteed appts/year". It does not define the guarantee or say what happens if the number is missed, and the billing period for the $5,000 is not stated on that line. No contract length is published.

Lead Cookie

Best for smaller B2B teams that want manual LinkedIn and email outreach at a published starting price. Its two products are Core Outbound Campaigns, described as tailored LinkedIn and email outreach with manual outreach, and Boutique Outreach Campaigns, a fuller LinkedIn and email campaign aimed at a highly specific market.

Its homepage lists Core "starting at $1,500 / month" and Boutique "starting at $3,700 / month". It says it has 14 in-house experts, 800+ campaigns and nine years in business, and shows a case study in which the client reports a 15.1x return in year one. Those are claims by Lead Cookie and its client. No contract terms appear.

The page does not say who owns the lists or sending accounts, or what a starting price leaves out. Source: Lead Cookie homepage, checked 18 October 2026.

EagleRev

Best for sales-led teams with spare closing capacity and deals worth $10k+ in lifetime value that want a fixed-length trial before any retainer. The product is a 45-day sprint of LinkedIn and email outreach in which a human caller phones interested replies, followed by an optional ongoing service called Pipeline Coverage.

Full pricing is sent in writing before the strategy call. The page says the sprint is a one-time payment with no recurring charges, no hidden per-meeting fees and no 6-month lock-ins. It says a meeting quota goes in the contract, and that if it misses the quota it keeps working for free until it hits it. You define "qualified" in good faith and no-shows do not count.

Its LinkedIn outreach runs through its own tool, InMailer.ai, and through what it calls dedicated, ID-verified profiles that you approve. LinkedIn's help page says it does not permit third-party software that automates activity on its site, so ask how this is handled and who carries the risk. EagleRev's own FAQ says it will not promise LinkedIn never changes its rules. Source: EagleRev homepage and LinkedIn help page, checked 18 October 2026.

SalesHive

Best for teams that want a US-based SDR team on a flat monthly fee and can accept a vendor that declines to promise a meeting count. The service covers sales strategy, list building, email outreach, cold calling and appointment setting.

Its pricing page describes one flat monthly fee that covers the SDR team, a strategist, its platform and data, with no setup fees and no dollar amounts. Its Starter, Growth and Crush plans differ in channels, SDR count and daily touches, from phone only with 100+ touches to two SDRs with 500+. Plans run month to month, and annual plans cost less per month with a longer commitment of unstated length. You owe nothing until you approve launch, and cancelling after launch needs written notice.

SalesHive says it does not guarantee a number of meetings. It commits to the daily outreach volume in your plan, weekly strategist tuning and access to your own login. Its core SDR team is described as 100% US-based, with offshore teams a separate option. Source: SalesHive pricing and SalesHive homepage, checked 18 October 2026.

Tibexa

Best for B2B companies with a proven offer and capacity for 20+ sales calls a month that want to own the system. Tibexa designs, builds and runs outbound systems: GTM strategy, cold email and outbound infrastructure, list building and CRM cleanup, and automation of qualification, routing and scheduling.

Clients own the infrastructure, data and copy, with no lock-in, and we judge success by booked meetings. Our planning benchmarks are 2 to 3 percent of sends replying, 15 to 50 percent of replies positive, and 30 to 50 percent of positive replies booking. In one engagement a PR and brand agency booked 130+ meetings, 24 of them in the first 12 days (case study).

Pricing is not published. We are a poor fit for pre-product startups, B2C companies and anyone who wants leads without sales follow-through, and we do not sell a standalone calling team. Source: Tibexa's own pages on cold email systems and GTM strategy, checked 18 October 2026.

Cleverly

Best for teams that want LinkedIn, cold email and calling from one provider and are willing to get pricing on a call. The service is done-for-you B2B outbound across LinkedIn lead generation, cold email, cold calling, appointment setting and outsourced SDRs.

No prices or contract terms appear on its site, only an offer of a free strategy call. Its homepage shows company-wide figures such as $312M pipeline generated, which are Cleverly's own claims with no method stated.

The homepage gives more than one client count (1,000 active clients in one place, 5,000+ clients in another), and one case-study block still holds placeholder text. Ask for a client list you can call. Source: Cleverly homepage, checked 18 October 2026.

What to check before you sign

Ask who owns the sending domains, mailboxes, lists and scripts if you leave, because in some arrangements the agency does and your sender reputation leaves with it. Get the definition of a qualified meeting, whether no-shows count, and the exit terms into the contract itself.

Check the sending rules your agency will operate under. Google's sender guidelines require bulk senders (5,000+ messages a day to Gmail) to authenticate with SPF, DKIM and DMARC and to support one-click unsubscribe, and they tell senders to keep the spam rate in Postmaster Tools below 0.10 percent and never reach 0.30 percent (Google). In the US, the FTC's CAN-SPAM guide says the law makes no exception for business-to-business email, requires you to honor opt-outs within 10 business days, and puts penalties at up to $53,088 per violating email (FTC). Rules differ outside the US, and this is not legal advice.

If an agency uses LinkedIn automation, read what LinkedIn says: it does not permit third-party software that scrapes or automates activity on its site, and members using such tools may have accounts restricted or closed (LinkedIn). Whether to accept that risk is your decision.

Questions

How much does a B2B lead generation agency cost?

Published figures in this list run from Lead Cookie's $1,500 a month starting price to SalesRoads' $11,950 per four-week program for one SDR. Callbox's own article cites $16,000 to $32,000 a month per pod. Several agencies publish nothing and quote on a call.

Do these agencies guarantee meetings?

Mostly not in the terms they publish. SalesHive says it does not guarantee a number. Belkins shows 100 guaranteed appointments a year at its starter price without defining the guarantee, and EagleRev says its contract carries a meeting quota and free work until it is met. Read the clause itself.

Which pricing model should I pick?

The models here differ: CIENCE charges per SDR plus a bonus, SalesRoads charges per program, SalesHive a flat monthly fee, EagleRev a one-time sprint. Whichever you choose, write down what counts as a qualified meeting before you sign.

Is B2B cold outreach legal?

In the US, the FTC says CAN-SPAM makes no exception for business-to-business email, so opt-out and sender-identity rules apply. Other regions have different rules, so check the law where your recipients are. This is not legal advice.
