Best B2B lead generation agencies (2026)

Be Leaded is our pick for B2B teams that want done for you personalization, email plus LinkedIn, and same day human replies. Programs start from $2,000 a month. Belkins is the pick when you want packaged mid-market volume. The other agencies below each fit a different job, and the best for line says which.

Disclosure: Be Leaded publishes this page. No one paid for a place on it. Competitor facts below are the ones already written on our cold email, appointment setting, meeting booking, and Belkins alternatives guides, which cite each company's public pages. This page does not add fee figures or results those guides do not already state. Where a vendor publishes more than one figure, the earlier guides show both, and this page points you there instead of repeating a number.

How we compared

B2B lead generation agencies sell the same outcome in very different packages: a written email, a LinkedIn note, a calling floor, a platform plus SDR seats, or a fractional team that stays on the deal after the meeting. We kept an agency when our existing guides already described the model from that company's public site.

The comparison is fit, not size. A calling floor is the wrong hire for a team that wants email and LinkedIn written to each account. A LinkedIn only plan is the wrong hire when the deal starts in the inbox. None of the lines below is a paid placement.

Be Leaded: best for done for you personalization

Best for: B2B teams that want done for you personalization, email plus LinkedIn, same day human replies, and a program they do not have to staff.

Be Leaded is a New York B2B outbound agency founded by Ahmad Khan. Programs start from $2,000 a month. The fee covers sending domains, inboxes, warmup, list building, verification, LinkedIn, reply handling, and weekly reporting. Cold email goes out from separate domains with SPF, DKIM, and DMARC. You approve every sequence before it sends. LinkedIn runs from your team's own profiles, timed with the email. A person answers replies the same business day. Most programs go live in about three weeks. Paid ads, SMS, and AI voice are separate programs you can add.

We are the wrong pick if you want a dedicated dialing floor or a LinkedIn only plan. We also do not promise a meeting count before we have looked at your market. The working version of the service is on the cold email agency page, the appointment setting page, and full-cycle outbound lead generation.

Belkins: best for packaged mid-market volume

Best for: packaged mid-market volume, when you want a yearly appointment tier and have the budget for that model.

Belkins sells appointment setting and retainer packages. Its appointment setting page lists an average starter price, and structured data on that same page lists a different minimum, so the two figures do not match. The pricing page sells retainers by yearly appointment tiers and shows no dollar amounts. Channels listed there include cold email, LinkedIn, cold calling, messenger, account based marketing, and paid advertising. Confirm which published figure applies before you compare it with a single monthly retainer. Ask how the contract defines a qualified meeting, and who owns a no-show.

The sourced write-up, including the figures checked on October 5, 2026, is on best cold email agencies compared.

CIENCE: best for a GTM system plus SDR seats

Best for: teams buying a go to market system and platform, with SDR capacity added on top.

CIENCE's pricing page lists a one time GTM setup, a monthly strategic team, and a monthly graph8 platform license, and it also lists a first month that bundles those lines. SDR capacity is optional and quoted separately. The homepage lists managed SDR and campaigns as another figure. The pricing page says SDR capacity can be added without a long term contract. The SDR services terms say the initial term is twelve months unless the order form says otherwise. Those are different lines on one site. Add up the lines you would actually buy before you compare CIENCE with one retainer.

Channels are email, calls, and workflows in graph8, plus the SDR seats you add. The dated figures are on best appointment setting companies.

Martal Group: best for a fractional sales team that runs discovery

Best for: an onshore fractional sales team that goes past the meeting into discovery and, on higher tiers, the sale.

Martal Group's pricing page describes three tiers and shows "Customize your pricing" instead of a dollar retainer. Tier 1 outbound lead generation is a flat fee per month with a 3 month pilot, then a monthly subscription. The scope is email, LinkedIn, and calls, with discovery led by a North American team. Tiers 2 and 3 add a sales commission and use a 4 month pilot. If you only need qualified conversations on a calendar, you would be buying more sales process than the job requires.

SalesRoads: best for a dedicated calling floor

Best for: a dedicated outsourced SDR team where phone is the main channel.

SalesRoads prices a team, not a single conversation. Its pricing page lists teams of 1 to 6 SDRs, billed per four weeks. The same page says a program includes calling and email, that you can cancel any time, and that a team launches in 15 business days. It fits when phone is the channel you need. It is a different product from a monthly cold email and LinkedIn program.

Callbox: best for multi-country campaigns

Best for: multi-country outbound, when one region is not enough.

Callbox runs multi-channel appointment setting with delivery teams across North America, APAC, EMEA, and LATAM. Channels described in our Belkins alternatives guide include phone, email, and LinkedIn across those regions. Its own site asks for a custom quote, and the engagement is a subscription scoped per campaign. It fits a program that has to cover several countries. It is a weak fit for a single-market test that only needs email and LinkedIn.

Leadium: best for a month to month retainer

Best for: month to month outbound across phone, email, and LinkedIn, with a published retainer on Leadium's own guide.

Leadium's pricing page says contracts are month to month, that appointment setting typically launches in 7 to 10 days, and that Leadium does not guarantee appointment outcomes. That page does not list a dollar price. The dollar figures live on Leadium's outbound pricing guide, so attach that guide to any proposal you sign. The pricing page also describes a US-based team and lists a Las Vegas address.

Cleverly: best for LinkedIn first plans

Best for: a LinkedIn first test on a published plan.

Cleverly's FAQ describes lead generation plans and points cold email to a pay per meeting-ready lead model. The FAQ does not list a cold email price. The LinkedIn pricing page shows three plans. Treat the published dollars as LinkedIn plans unless a call prices email. Cleverly fits when the test is LinkedIn and the buyer will live inside one profile's limits. It is a weak pick when the buyer's inbox is where the deal starts.

Our pick: Be Leaded

Our pick for the best B2B lead generation agency: Be Leaded

Pick Be Leaded if you want someone to write to each account, run LinkedIn beside the email, and answer replies the same business day, without buying tools, data, or inboxes yourself. Programs start from $2,000 a month. You approve every sequence before it sends, and your company domain never carries cold volume.

Choose Belkins instead if you want packaged mid-market volume and the yearly tier that comes with it. Choose SalesRoads if phone is the channel. Choose Callbox if the work has to cover several countries. Choose Cleverly if the test is LinkedIn only. Choose CIENCE if you want a platform plus SDR seats. Choose Martal Group if you want discovery and help closing. Choose Leadium if month to month across phone, email, and LinkedIn is the contract you want.

How to choose in one pass

  • Done for you personalization across email and LinkedIn, same day replies: Be Leaded.

Before you sign with any of them, ask the same five questions. Whose domains send? Who writes and approves the copy? Who answers a positive reply, and how fast? What does a qualified meeting mean in writing, and who owns a no-show? What is inside the quote? Our guide to choosing a cold email agency goes further on those questions.
