How we built this list

A practitioner read, not a reposted directory

We verified each agency on its own current site in July 2026: what they run, who they serve, their engagement model, and any pricing they publish. We featured genuine outsourced and fractional SDR firms, the ones that staff reps who prospect for you, and read the Clutch reviews behind each.

We run outbound ourselves, as the two founders rather than a pod, so the read on each shop comes from knowing the work. Where an agency had no independent review sample we could trust, we left the rating off rather than invent one.

How we built this list

→ Every agency verified on its own current site, July 2026
→ Ratings shown only where a credible independent sample exists, linked and dated
→ No affiliate links, no paid placements, no pay-to-list
→ We publish this list and we are on it. We do not rank ourselves first, and we say where we are not the fit
→ Grouped by fit, not ranked. If a fact could not be verified, we left it out

The real test

Senior firepower, or a full-time pool?

The fractional question is really a question about who does the work. Do you buy a few days a week of a senior operator's expertise, or rent a full-time pool of junior reps dialing to a target? The first fits a seed to Series A team with a complex sale; the second fits a proven, high-volume motion. The right one depends on your deal and your stage.

Full-time pool

You rent headcount at scale

A larger, often blended or offshore team runs high activity against your list and books meetings to a target. It fills a calendar fast and costs less per meeting. Watch the show-rate and the qualification bar.

Use it when your motion is proven and volume, not nuance, wins.

Fractional senior

You buy expertise, not headcount

A senior, usually onshore operator works your account part-time, running more consultative outreach and calls and booking fewer but better-qualified meetings. Costs more per meeting, converts better on complex sales.

Use it when you are seed to Series A and the conversation carries the deal.

The through-line

Either way, ask two things before you sign: how do you define a qualified meeting, and can I read recent reviews on show-rate and lead quality? The gap between a booked meeting and a real opportunity is where SDR programs quietly fail.

The agencies

The fractional SDR agencies, grouped by job

Grouped by what they are best at, not ranked one to eleven. Read the group that matches where you are.

Group A

Managed appointment-setting pods

Done-for-you teams that run multi-channel outreach and book meetings on your behalf, at scale. The pick when you know your ICP and want coverage without hiring.

01

Belkins

4.9 Clutch 230+ Omnichannel

A large B2B appointment-setting agency that runs done-for-you omnichannel outreach across email, LinkedIn, and calling, with a dedicated SDR pod per client.

Best for

Mid-market and funded teams that know their ICP and want proven, high-volume appointment setting.

Model & pricing (Jul 2026)

Managed done-for-you service. Packages tied to appointment volume, quoted on a sales call. Pricing is not published.

Where they're strong

One of the largest positive review samples in the category and omnichannel appointment setting at scale.

Consider elsewhere if

You want a strictly US-onshore team or a single fractional SDR. Some reviews note booked-meeting counts falling short of the package.

Bottom line

The high-volume default once you have budget and a sharp offer. Confirm current terms directly.

02

CIENCE

4.2 Clutch 142 SDR-as-a-service

A large, long-running SDR shop that pairs human reps with its own data and AI tooling, and one of the very few in the field with fully itemized public pricing.

Best for

SMB to enterprise that wants outsourced SDRs with the option of a lower-cost offshore team.

Model & pricing (Jul 2026)

Month to month, no long contract. Published at about a $5,000 setup plus $2,000 a month, with SDRs from $1,500 a month.

Where they're strong

Genuinely transparent itemized pricing, large operating scale, and an onshore-or-offshore choice.

Consider elsewhere if

You want the highest-rated reviews here. Its 4.2 score trails others, with notes on lead quality and turnover, so read recent reviews first.

Bottom line

The most price-transparent option, with an offshore tier that lowers the floor.

03

Callbox

4.6 Clutch 119 Global

One of the oldest names in the category, running since 2004, with delivery teams across seven countries for genuinely global and cross-border outbound.

Best for

Mid-market and enterprise that need coverage across regions, or outbound into APAC and other cross-border markets.

Model & pricing (Jul 2026)

Subscription-based managed service, quoted per campaign scope. No public figure.

Where they're strong

A twenty-year track record and multi-region delivery across US, UK, APAC, and more, under one roof.

Consider elsewhere if

You want published pricing or a small, senior team. It is quote-only and built for larger multi-region programs.

Bottom line

The pick when your outbound has to cross borders and timezones.

04

Leadium

Las Vegas, US Data-led

A done-for-you SDR partner that leans on human-sourced, validated contact data across email, phone, LinkedIn, and SMS.

Best for

SMB to enterprise that want outsourced appointment setting with an emphasis on clean, researched data.

Model & pricing (Jul 2026)

Managed outsourced SDR service, quoted per scope. No public figure; the intake references budgets from $2,500 up.

Where they're strong

Human-validated contact research and omni-channel appointment setting, with 1,500+ sales orgs served.

Consider elsewhere if

You need published pricing or an independently verified rating; the public review trail is thin.

Bottom line

Worth a look for data-quality-led outbound; ask for recent, referenceable results.

Visit Leadium Verified Jul 2026

Group B

Senior onshore reps

Experienced, mostly onshore sales reps who run consultative outreach and calling, booking fewer but better-qualified meetings. The pick when your sale is complex and the conversation matters.

05

Martal Group

4.8 Clutch 109 Onshore reps

An outsourced sales team of experienced North American reps, running since 2009, now paired with an AI-powered outbound platform.

Best for

Funded startups to enterprise that want senior onshore sellers, not junior SDRs, on their outbound.

Model & pricing (Jul 2026)

Tiered retainer with a multi-month pilot, then monthly. Quoted on request.

Where they're strong

All-onshore senior reps, a long track record since 2009, and strong recent Clutch recognition on a large sample.

Consider elsewhere if

You want no minimum or fully transparent pricing. It asks for a multi-month pilot and is steep at seed.

Bottom line

The senior-seller pick for funded teams selling into North America.

06

SalesRoads

4.9 Clutch 66 Onshore, no lock-in

A US-based appointment-setting firm that stakes its pitch on rep quality: reps with real tenure, plus rare cancel-anytime terms and public starting prices.

Mid-market and enterprise that value senior onshore reps and want no long-term lock-in.

Model & pricing (Jul 2026)

Dedicated US teams on a retainer, cancel anytime. Published: appointment setting from $9,950 per four weeks.

Where they're strong

The highest Clutch score here, genuinely no-commitment terms, and all-onshore experienced reps.

Consider elsewhere if

You are seed-stage or budget-constrained; the roughly $9,950 per four weeks floor is the steepest entry point here.

Bottom line

Premium onshore reps with the rare freedom to cancel anytime.

07

EBQ

Austin, US Onshore department

An Austin-based outsourced sales-execution firm whose SDR-as-a-service supplies a full US-based BDR team for cold calling, inbound follow-up, qualification, and appointment setting.

Best for

Mid-market and enterprise B2B needing a managed onshore calling team for complex sales cycles.

Model & pricing (Jul 2026)

Per-SDR monthly retainer, quoted per scope. Not published on their site.

Where they're strong

Eighteen-plus years of process, a fast ramp with reps dialing within days, and full-department coverage across the buyer journey.

Consider elsewhere if

You want published transparent pricing, an offshore option, or a single lightweight fractional SDR.

Bottom line

A deep onshore BDR department for complex, calling-led sales.

08

Sales Focus Inc

Columbia, US 100% onshore

A US-based sales-outsourcing pioneer, since 1998, that recruits, trains, and manages dedicated 100% onshore inside-sales reps as a managed team, launching a program in 45 days or less.

Best for

B2B teams that specifically want a fully onshore, W-2, background-checked dedicated rep or team.

Model & pricing (Jul 2026)

Published per US rep: $4,650 to $5,850 a month, plus a one-time startup fee scaled by team size.

Where they're strong

The longest track record here, true 100% onshore W-2 staffing, transparent per-rep pricing, and a fast 45-day launch.

Consider elsewhere if

You want a low-cost offshore option, a modern email and LinkedIn signal motion, or a large online review sample.

Bottom line

The choice when fully onshore, employed reps and transparent pricing are non-negotiable.

Group C

Build-plus-hire and flexible

SDR programs with a twist: some train and recruit reps you can eventually hire, others flex between onshore and offshore on no-lock-in terms. The pick when you want more than a fixed pod.

09

memoryBlue

Tysons, US Build-plus-hire

A sales-development specialist for B2B tech that pairs outsourced SDR programs with sales training and recruiting, so it can also build your in-house team.

Best for

Funded B2B tech, including public-sector vendors, that want outsourced SDRs with a path to hiring the reps.

Model & pricing (Jul 2026)

Outsourced SDR programs plus training and recruiting, quoted per scope. No public figure.

Where they're strong

Twenty-plus years in sales development, deep tech and cybersecurity expertise, and a rare build-plus-hire model backed by an alumni network.

Consider elsewhere if

Bottom line

The pick when you want outbound now and your own SDR team later.

SalesHive

Denver, US Onshore or offshore

A US-based, AI-assisted B2B sales agency that provides dedicated outsourced SDRs, US or Philippines, running cold calling and email, on flat monthly pricing with no long-term contract.

Best for

SMB to mid-market teams that want flexible, no-lock-in outsourced calling and email with a budget choice.

Model & pricing (Jul 2026)

Tiered flat monthly retainers, month to month, no setup fee. US and Philippines options, with a US strategist over the account.

Where they're strong

Bottom line

The flexible, no-lock-in option when you want to test outbound without a long contract.

Group D

The founder-led alternative

Not an SDR staffing shop at all: the two founders run outbound themselves as a senior alternative to renting reps. The pick at seed and early stage, when you want operators testing the motion, not a pod dialing a script.

11

Real Good GTM (that's us)

Paris · US/Europe Founder-led · signal-based

The two of us run signal-based outbound on email and LinkedIn for seed to early Series A startups in the US and Europe. Not a rented SDR pod, the founders do the work, and you get booked pipeline plus a clear read on what to scale.

Best for

Seed to early Series A founders who want senior operators on the account, not junior reps dialing a script.

Model

A two-month start, then month to month, no lock-in. Pricing is custom, scoped on a fit check.

Where we're strong

Founder-led delivery, signal-based rather than volume-based outbound, and a live learning document on what actually converts and who really buys.

Not for you if

You need cold calling, enterprise-scale meeting volume, guaranteed meeting counts, or a big SDR team. That is not us.

Straight talk

We are the alternative to renting SDRs, not another pod. If outbound is not right for you yet, we will say so on the call.

How to choose

Who each one is for

Find your situation below and start with the agency next to it. A sensible starting point, not the only right answer.

You know your ICP, want volume

Belkins or Callbox for proven, multi-channel appointment setting.

Complex sale, senior buyers

Martal Group or SalesRoads for experienced onshore reps.

You want transparent pricing

CIENCE or Sales Focus, both with published rates.

You want no long contract

SalesRoads or SalesHive, both built for cancel-anytime terms.

You will hire SDRs later

memoryBlue to outsource now and recruit your own team over time.

Seed, still finding the pitch

Real Good GTM (that's us), founders testing the motion, not a pod dialing a script.

Putting it together

How we'd actually choose

We run outbound as the two founders, not a pod, so here is the order we would run the decision in, whether or not we are on your list.

1

Match reps to your sale

A complex, senior sale needs experienced onshore reps. A simpler, high-volume motion can use a blended or offshore pod. The rep profile matters more than the logo.

2

Pressure-test the pipeline

Ask how they define a qualified meeting, and read recent reviews on show-rate and lead quality. A booked meeting is not yet an opportunity.

3

Mind the commitment

Favor month-to-month or cancel-anytime terms over a long lock-in tied to a guaranteed appointment count. Flexibility protects you when the fit is not right.

FAQ

Questions people ask

What is the difference between a fractional SDR and an outsourced SDR agency?

A fractional SDR is a single part-time rep, often senior, who prospects for you a few days a week. An outsourced SDR agency gives you a managed team, one or more dedicated reps plus researchers and managers, running outreach on your behalf. Most of the firms on this page are outsourced agencies; true single fractional reps are rarer. Both rent you prospecting capacity you do not have to hire and manage yourself.

How much does an outsourced SDR agency cost?

Pricing is usually per dedicated rep on a monthly retainer. Where it is public, CIENCE lists about a $5,000 setup plus $2,000 a month with SDRs from $1,500, Sales Focus publishes roughly $4,650 to $5,850 a month per US rep, SalesRoads starts at $9,950 per four weeks. Belkins and many others quote per scope. Expect a floor near $4,000 to $6,000 a month for a serious onshore program.

Onshore or offshore reps, which is better?

Onshore reps cost more but tend to handle complex, senior conversations and calling better, and they sit in your buyers' timezone. Offshore reps lower the price and can work for simpler, higher-volume motions. Some agencies, like CIENCE and SalesHive, let you choose. Match the rep to how consultative your sale is, not just to the budget.

How is an SDR agency different from a cold email agency?

An SDR agency rents you reps who prospect across phone, email, and LinkedIn, and you pay largely for their activity and the meetings they book. A cold email agency is built around one channel and its deliverability. If calling is central to your motion, you want an SDR team; if inbox placement and email at scale are the job, a cold email specialist fits better. Some buyers use both.

Should an early-stage startup outsource SDRs?

Usually not before you have found a repeatable message. Outsourced SDRs execute a motion; they do not discover one. If you already know your ICP and what resonates, a team can add capacity fast. If you are still figuring out the pitch, a senior, founder-led outbound approach that tests and learns will waste less money than a pod dialing an unproven script.

Do outsourced SDR agencies guarantee meetings?

Some sell packages tied to an appointment count, which sounds reassuring but often pushes volume over quality and can mean a loose definition of a qualified meeting. No one controls your market or your offer. A better sign is transparency about process, rep tenure, and real pipeline, plus flexible terms, over a guaranteed number. Read recent independent reviews before you sign.
