Cover image reading: Top 10 Outbound Agencies for B2B Tech Companies (2026).

Quick answer

The best outbound agencies for B2B tech companies in 2026 are Cymate, Understory, Frontal, SalesCaptain, Belkins, Martal Group, Leadium, CIENCE, SalesRoads and Callbox. Cymate is first because this is our list. Pick by how you want to reach buyers: mostly email, email plus phone calls, or phone first. Facts checked November 9, 2026.

Key takeaways

  • Match the agency to how you sell. Cymate, Understory, Frontal and SalesCaptain run outbound by email and LinkedIn. Belkins, Martal Group, Leadium, CIENCE and Callbox also list phone calls, and SalesRoads leads with the phone.

  • Four of the ten publish a price: Belkins, CIENCE, SalesRoads and Callbox. Each prices a different unit (a plan, an SDR, a 4-week cycle, a pod), so compare the full monthly cost for the same work.

  • Cymate, CIENCE and Leadium are month to month, and SalesRoads says you can cancel anytime. Frontal starts with 3 months and Martal Group with a 3-month pilot. The other four don't publish a term.

  • Cymate fits funded B2B tech teams that want email-led outbound. Our case studies include meetings at Coinbase, Visa and CreditKarma (Copybara) and NatWest and BBVA (Kinetica).

  • Before you sign with anyone, including us, get three things in writing: what counts as a qualified meeting, who owns the domains and data if you leave, and the minimum term.

Facts checked November 9, 2026.

Say you run sales at a Series A software company. Your reps are booking their own meetings, the board wants more pipeline, and you've decided to bring in an outbound agency. So you search for the best outbound agencies, and most of the lists you find were written by agencies or sales software companies.

This one was too. I run Cymate, an outbound agency, so we're on this list and we put ourselves first.

For each one, you'll see what it's best for, its channels, its price and term, and the proof on its own site. Each published price links to the page it came from.


Infographic listing 10 outbound agencies for B2B tech and what each is best for: 1. Cymate, email-led outbound at funded B2B tech teams. 2. Understory, outbound and paid media from one team. 3. Frontal, GTM engineering on Clay. 4. SalesCaptain, signal-led outbound in the US and Europe. 5. Belkins, multichannel outbound with calling. 6. Martal Group, onshore sales reps across email, LinkedIn and phone. 7. Leadium, month-to-month omnichannel appointment setting. 8. CIENCE, adding managed SDRs by headcount. 9. SalesRoads, phone-first outbound. 10. Callbox, programs across several countries and languages. Cymate is first because it's Cymate's list; the other nine aren't ranked.

What is an outbound agency?

An outbound agency is an outside team that books sales meetings for B2B companies by reaching buyers who haven't contacted you yet. It works through cold email, LinkedIn, phone calls or a mix of the three.

Most handle the whole process: who to target, the lead lists, the sending setup, the messages, the replies and the booked meetings. Some sell it as appointment setting, which focuses on booking the meetings. Others sell an outsourced SDR (sales development rep) team: reps who work your accounts for you.

This list leaves out call centers, recruiting firms and software you run yourself.

Which outbound agencies are best for B2B tech companies?

The 10 best outbound agencies for B2B tech cover four ways of working: email-led programs, multichannel teams that also call, phone-first SDR teams, and SDRs you add by headcount. Prices and terms come from each agency's own site, checked November 9, 2026, and ratings come from Clutch.

Cymate's #1 spot is our call. The other nine are grouped by what they do best, not ranked.

How did we pick these 10 outbound agencies?

This is Cymate's list. We run outbound for B2B tech companies, so we're one of the agencies on it, and we put ourselves first because it's our blog. The other nine aren't ranked against each other.

Every agency had to pass five checks:

  1. It serves B2B tech or SaaS companies, and its own site says so.

  2. Outbound is its main service, and it runs the work for you.

  3. It shows proof: case studies with numbers or named clients, Clutch reviews, or both.

  4. It's active in 2026, with a live site and current pricing, case studies or reviews.

  5. It fits funded companies (Series A and up, or bootstrapped with real budget).

Facts come from each agency's own site, plus Clutch for ratings and Clay's partner directory for one price, all checked on November 9, 2026. "Not public" means we couldn't find it on the agency's site that day. We left out call centers, recruiting firms, agencies built mainly for very small budgets, and software you run yourself.

No agency paid to be on this list. If something here is wrong, email admin@cymate.io and we'll fix it.

We also run outbound for our own pipeline. It sends about 40,000 to 50,000 emails a month from about 200 inboxes and books 80 to 100 meetings. That's how we scaled Cymate to seven figures with cold email.

Which outbound agencies made the list, and what is each best for?

All ten run outbound for B2B tech companies. What separates them is the channel mix, how they price, the minimum term and where their reps sit.

1. Cymate: best for email-led outbound at funded B2B tech teams

Cymate (that's us) runs email-led outbound for funded B2B tech companies, mostly in North America. We build lead lists from buying signals like hiring, new funding and leadership changes.

  • Based in: the Bay Area; founded in 2022

  • Channels: cold email, plus LinkedIn outreach

  • Price (checked November 9, 2026): not public; a flat monthly fee, quoted on a call

  • Minimum term: month to month

  • Reviews: no Clutch profile; 30 published case studies

Proof: Copybara's enterprise outbound case study shows $500K+ in qualified pipeline and 15+ enterprise meetings a month within 6 months, including Coinbase, Visa and CreditKarma. We also reached data leaders at NatWest and BBVA for Kinetica, and Dynasty's 120+ deals in pipeline came in 2 months, including Morgan Stanley.

Strengths: a dedicated team on every account, including an outbound strategist, GTM (go-to-market) engineer, campaign manager, SDR and copywriter. Setup takes about 21 days, and we target the first qualified meeting at 21 to 30 days.

Watch for: we're email-led, so we're not the pick for a team that wants cold calling, and our price isn't public.

Pick someone else if you need cold callers (SalesRoads, Belkins), paid media in the same retainer (Understory, Frontal) or programs outside North America (Callbox, Martal Group).

2. Understory: best for outbound and paid media from one team

Understory is an "allbound" B2B growth agency for growth-stage and enterprise SaaS companies. One team runs paid media, outbound built in Clay (a tool for building and enriching lead lists), LinkedIn content and RevOps (revenue operations). You can hire it for one service or all four.

  • Based in: Miami, Florida; founded in 2021

  • Channels: cold email and LinkedIn outreach, plus paid media on LinkedIn, Google, Meta, Reddit, X and Substack

  • Price (checked November 9, 2026): custom flat retainers; amounts not public (its company facts page)

  • Minimum term: not public

  • Reviews: no Clutch reviews yet

Proof: its site lists 14 case studies. FullPAC got "nearly $10M in outbound pipeline from under $60K in spend", with about 75 meetings in the first 3 months. For hapily, it reports "39 deals, 5 closed won and ROI positive on outbound by month five".

Strengths: one team for outbound and paid media, with RevOps on HubSpot or Salesforce behind it. Each engagement gets at least a GTM engineer, a GTM operations manager and a paid-media strategist, per its site.

Watch for: the price and minimum term aren't public, and its site says cold email campaigns start late in month 1 or early in month 2.

Pick Understory over Cymate if you want paid media and outbound run by one team.

3. Frontal: best for GTM engineering on Clay

Frontal, formerly ColdIQ Agency, is a GTM agency for B2B tech companies from Series A onward, "with a real sales team." It builds signal-based outbound on Clay and also runs account-based marketing (ABM), paid media, content and RevOps.

  • Based in: Cheyenne, Wyoming, per Clutch; ColdIQ Agency became Frontal in 2026

  • Channels: signal-based outbound, ABM, paid media, content

  • Price (checked November 9, 2026): not public, set on a call; its Clay partner profile lists $5,000+ a month

  • Minimum term: starts with a three-month engagement

  • Reviews: Clutch 5.0 (16 reviews)

Proof: AirOps reports "$7.83M qualified pipeline in 10 months", and Design Pickle went "from about 10 demos a week to 58 in 14 days".

Strengths: Frontal is a Clay Elite Studio partner, the top tier of Clay's partner program, and has built Clay workflows since 2022. It works inside the tools your team already uses, such as HubSpot, Salesforce or Attio.

Watch for: work starts with a three-month engagement, and the price depends on the services in scope.

Pick Frontal over Cymate if you want Clay-based GTM engineering plus ABM, paid media and RevOps in one engagement.

4. SalesCaptain: best for signal-led outbound in the US and Europe

SalesCaptain builds outbound on B2B data, including intent, funding and revenue signals, for SaaS, services and enterprise companies. It runs campaigns across cold email, LinkedIn and text messages, and helps international brands expand across the US and Europe.

  • Based in: New York, per Clutch, with an office in London; founded in 2021

  • Channels: cold email, LinkedIn, text messages

  • Price (checked November 9, 2026): not public

  • Minimum term: not public

  • Reviews: Clutch 4.7 (23 reviews)

Proof: its site lists 27 case studies. GlossGenius got 253 positive replies in 5 months, and a global recruitment service got 501 booked appointments and $394K ARR (annual recurring revenue) in 10 months.

Strengths: lists built from intent and funding data, with Clay and AI workflows behind the campaigns. Text messages sit alongside email and LinkedIn, and the London office suits teams selling into Europe.

Watch for: the price and terms aren't on its site, so get both in writing.

Pick SalesCaptain over Cymate if you want a team with a London office, or text messages in the mix.

5. Belkins: best for multichannel outbound with calling

Belkins is a B2B lead generation agency that books appointments through cold email, calls, LinkedIn, SMS and WhatsApp, and paid ads. It sells monthly retainer plans built around a yearly number of appointments.

  • Based in: Denver, Colorado, per Clutch; founded in 2017

  • Channels: cold email, cold and intent-based calling, voicemail, SMS and WhatsApp, LinkedIn, paid ads

  • Price (checked November 9, 2026): from $5,000, its "average starter price" for cold email; a Belkins article puts email-only plans from $6,500 and omnichannel from $7,995 a month

  • Minimum term: not public

  • Reviews: Clutch 4.9 (234 reviews)

Proof: Omnicharge got 320+ appointments in 12 months and won 9 deals in the first 3 months. A sustainability SaaS company got 56 opportunities with enterprise clients and $2.2M in total pipeline.

Strengths: the widest channel mix on this list, including calling. Its pricing page lists a Growth plan with 100+ appointments a year and Growth Plus with 200+. The Enterprise tier adds custom SLAs (service-level agreements) and support for SOC 2, ISO and data-privacy requirements.

Watch for: starting prices run from $5,000 for cold email to $7,995 a month for omnichannel, and the term isn't public, so get a written quote.

Pick Belkins over Cymate if you want cold calling and a yearly appointment target written into the plan.

6. Martal Group: best for onshore sales reps across email, LinkedIn and phone

Martal Group provides outsourced sales reps who run outbound by email, LinkedIn and phone for B2B companies, including tech and SaaS. Its site says it has "200+ onshore sales executives", based in the US (60%), Canada (20%), Europe (10%) and Latin America (10%).

  • Based in: Oakville, Canada, per Clutch; founded in 2009

  • Channels: cold email, LinkedIn, cold calling

  • Price (checked November 9, 2026): a flat monthly fee for its outbound tier, amount not public; its sales tiers add a commission (Martal's pricing page)

  • Minimum term: a 3-month pilot for the outbound tier, then a monthly subscription

  • Reviews: Clutch 4.8 (110 reviews)

Proof: about 20 case studies on its site. One example shows 145 booked meetings and 158 SQLs (sales-qualified leads) over 27 months, from 58,126 emails and 19,224 calls.

Strengths: one program covers email, LinkedIn and calls, with 5 to 7 touch points per prospect. Its pricing page shows the monthly funnel to expect, such as 3,000 to 5,000 prospects and 20 to 30 qualified leads.

Watch for: the fee isn't public, and you start with a 3-month pilot (4 months for the sales tiers).

Pick Martal Group over Cymate if you want onshore reps who call as well as email.

7. Leadium: best for month-to-month omnichannel appointment setting

Leadium is an outbound sales agency that runs appointment-setting campaigns by email, phone, LinkedIn, SMS and gifting. Its industry pages include cybersecurity, SaaS and freight logistics.

  • Based in: Las Vegas, Nevada, per Clutch; founded in 2016

  • Channels: email, phone, LinkedIn, SMS, gifting

  • Price (checked November 9, 2026): not public

  • Minimum term: month to month (Leadium's pricing page)

  • Reviews: Clutch 5.0 (90 reviews)

Proof: Mindtickle saw a "200% increase in quota attainment" from a US-based cold-calling program, and Mitek a "4x increase in qualified leads per quarter".

Strengths: all its contracts are month to month. Appointment setting launches in 7 to 10 days, and gifting and SMS add ways to reach buyers beyond email.

Watch for: the price isn't public, and new clients start on the 1st or 15th of the month, with a set number of openings.

Pick Leadium over Cymate if you want SMS, gifting and calling in the mix on month-to-month terms.

8. CIENCE: best for adding managed SDRs by headcount

CIENCE books sales meetings for B2B teams with managed SDRs who call, email and use LinkedIn. Since 2025 it has been part of graph8, which also sells a GTM software platform.

  • Based in: Miami, Florida, per its own site; started in 2016, per graph8

  • Channels: calls, email, LinkedIn

  • Price (checked November 9, 2026): $2,000 a month for the campaign team, $499 a month for the graph8 platform, and SDRs from $1,750 a month each (offshore) or $3,500 (US and Europe) (CIENCE's pricing page)

  • Minimum term: month to month

  • Reviews: Clutch 4.2 (142 reviews)

Proof: SendBird got 227 appointments in 4 months, and Mandolin got 110 qualified meetings in 6 months.

Strengths: a published, itemized price list. You can add or remove SDRs month to month, and its pricing page says campaigns go live in less than 14 days.

Watch for: the cost grows with headcount (its own example puts five offshore SDRs at $11,249 a month), and a performance bonus and setup fee come on top.

Pick CIENCE over Cymate if you want to add or remove SDR headcount month to month.

9. SalesRoads: best for phone-first outbound

SalesRoads gives B2B companies dedicated outsourced SDRs who lead with phone calls, backed by personalized email. Its industry pages include SaaS, manufacturing, healthcare and the public sector.

  • Based in: Boca Raton, Florida, per Clutch; founded in 2007

  • Channels: outbound calling, email

  • Price (checked November 9, 2026): $11,950 per 4-week engagement for one SDR, and $16,750 for two (SalesRoads' pricing page)

  • Minimum term: "No long-term commitment. Cancel anytime."

  • Reviews: Clutch 4.9 (69 reviews)

Proof: Layfield got $1.25 million in pipeline in 15 weeks, and AchieveIt got 937 appointments with local government.

Strengths: a published price for each team size, and every program includes a client strategist, an SDR performance coach and a research and data team. Programs launch in 15 business days.

Watch for: billing runs in 4-week cycles rather than calendar months, so compare prices on the same basis.

Pick SalesRoads over Cymate if your buyers answer the phone and you want callers first.

10. Callbox: best for programs across several countries and languages

Callbox is a B2B lead generation agency that brings email, LinkedIn and phone into one coordinated campaign. It has 6 offices on 4 continents and runs region-specific campaigns in more than 15 languages.

  • Based in: Encino, California; founded in 2004

  • Channels: phone, email, LinkedIn

  • Price (checked November 9, 2026): about $6,667 a month per "campaign pod" (one dedicated SDR with campaign manager oversight); exact price after a consultation (Callbox's pricing page)

  • Minimum term: not public

  • Reviews: Clutch 4.6 (128 reviews)

Proof: its site shows 146 sales appointments over 12 months for a US logistics company. It also shows 70 sales-qualified leads over 4 months for an enterprise managed-services firm.

Strengths: multi-country, multi-language programs from one team. Each pod targets one market segment or persona, so you scale by adding pods.

Watch for: the price is an estimate until the consultation, and the contract length isn't public.

Pick Callbox over Cymate if you run programs across several countries or languages.

How much does an outbound agency cost?

Prices were checked on November 9, 2026. To compare, ask each agency for one monthly number that covers everything, then divide it by the qualified meetings you expect.

How do I choose an outbound agency?

Ask every agency on your shortlist for the same five things, including us:

  1. Results from a company like yours, with the timeframe and the number of emails behind them.

  2. The unit those results are counted in. Between them, the ten agencies here report positive replies, booked appointments, qualified meetings, SQLs, pipeline and ARR.

  3. A written definition of a qualified meeting.

  4. Who owns the domains, inboxes and lead data if you leave.

  5. The minimum term, and how you get out.

Here are our answers. Our own outbound takes roughly 500 emails per booked meeting. A meeting counts as qualified when the lead matches the targeting we agreed on: industry, company size, revenue and role.

Budget, authority, need and timing are for your team to judge on the call. If you leave, you keep the domains, inboxes, lead data and copy, and our terms are month to month.

For all 10 checks, see how to choose an outbound agency.

Should I hire an outbound agency or an in-house SDR?

Hire in-house once your playbook is proven and a manager has time to coach. Until then, an agency is usually the cheaper way to get held meetings.

In our cost model, one in-house SDR costs about $10,971 a month fully loaded and books about 9 meetings, or $1,219 each. An agency on a $5,000 retainer (a typical published price, not ours) plus $1,492 of your manager's time costs $6,492 a month.

That agency is cheaper once it delivers more than 5.3 held meetings a month. The full math is in in-house SDR vs outbound agency.

The bottom line

The best outbound agency is the one that fits how you sell. If your buyers pick up the phone, start with SalesRoads or one of the multichannel teams. Understory and Frontal make sense when you want paid media in the same retainer.

And if you're a funded B2B tech company that wants email-led outbound built on buying signals, that's what our outreach management service does. Whoever you talk to, get the meeting definition, ownership and minimum term in writing before you sign.

If you'd like to see whether we're a fit, you can Run a Trial. It starts with a 25-minute call about your product, your market and your goals.

Frequently asked questions

What is the best outbound agency for B2B tech companies?

There isn't one best agency for everyone. The right pick depends on your channels, budget, contract length and region. If phone calls matter, look at Belkins, Martal Group, Leadium, CIENCE, Callbox or phone-first SalesRoads. For outbound plus paid media, look at Understory or Frontal, and for email-led outbound, look at Cymate or SalesCaptain.

How much does an outbound agency cost?

Four of the ten agencies here publish prices: Belkins from $5,000, CIENCE from $2,000 plus $499 plus $1,750 per offshore SDR a month, SalesRoads $11,950 per 4 weeks for one SDR, and Callbox about $6,667 a month per pod. The others, including Cymate, quote after a call. Compare the full monthly cost for the same work. Prices were checked on November 9, 2026.

How long does an outbound agency take to book the first meeting?

Plan for a few weeks of setup. CIENCE says it goes live in less than 14 days, Leadium launches appointment setting in 7 to 10 days, and SalesRoads launches in 15 business days. At Cymate, setup takes about 21 days and we target the first qualified meeting at 21 to 30 days. A launch date isn't a meeting, so ask each agency when to expect the first held meeting.

Which outbound agencies offer month-to-month contracts?

On this list, Cymate, CIENCE and Leadium are month to month, and SalesRoads says you can cancel anytime. Frontal starts with a three-month engagement and Martal Group with a three-month pilot. Get the term and notice period in writing either way.

Is an outbound agency the same as an SDR agency?

Mostly. An outsourced SDR service gives you reps who work your accounts, and appointment setting focuses on booking the meetings. Most outbound agencies do both, by email, LinkedIn, phone or a mix. On this list, Belkins, Martal Group, Leadium, CIENCE, SalesRoads and Callbox list phone calls as a channel, and Cymate is email-led.

Who owns the domains, inboxes and lead data if I leave an agency?

It depends on the contract, so get it in writing before you sign. At Cymate, clients keep the domains, inboxes, lead data and copy when they leave. If an agency keeps the domains, your next team has to warm up new ones from scratch.
