Hiring an in-house SDR team is slow and expensive. You recruit, ramp, buy data and tools, hire a manager, and then replace reps when they get promoted or leave. Outsourced SDR companies take that function on for you: they provide dedicated or embedded sales development reps who prospect your target accounts, qualify interest and hand booked meetings to your account executives.
SDR outsourcing is not the same as buying appointments. The firms on this list assign named reps to your account, train them on your product, and usually run them inside your CRM, so the work looks and feels like an extension of your own team. If you only need booked meetings and are less concerned with who sets them, our list of appointment setting companies covers that model.
This guide is for sales leaders, founders and CROs who want a dedicated SDR team without building one from scratch. It also suits companies that want to test a new market or segment with outsourced reps before committing headcount. For a wider view of the category, see our roundup of B2B sales outsourcing companies.
We checked each company’s own website, press releases and public profiles to confirm its SDR model, where its reps are based, how teams are managed and what it publishes about pricing and results. We favored firms that offer dedicated (not pooled) reps, explain their management and coaching structure, and publish named case studies. No company paid to be included.

Best Outsourced SDR Companies To Hire In 2027
1. memoryBlue — Dedicated SDR Teams With An Audition-To-Hire Path Since 2002
memoryBlue was founded in 2002 and is headquartered in Tysons, Virginia. In July 2023 it acquired Operatix, a London based sales acceleration firm founded in 2012, which expanded memoryBlue’s coverage into Europe and Asia. Today it lists seven offices: Tysons, Boston, Austin, Dallas and Denver in the US, plus London and Singapore.
Its model is built around dedicated outsourced SDRs who generate outbound pipeline and book meetings, with ADRs to qualify and progress opportunities and AEs available for discovery through close. memoryBlue says it has more than 650 dedicated SDRs, ADRs and AEs, with reps who speak over 30 languages, and that it has served more than 3,000 clients.
The feature that sets it apart is the audition-to-hire option: clients can hire memoryBlue reps onto their own teams once they have proven themselves. That turns the outsourced program into a recruiting pipeline as well as a pipeline generator, which suits companies planning to build an internal team later.
Best for: B2B technology companies that want embedded SDRs now and the option to hire the best reps directly.
2. SalesRoads — 500+ Outsourced SDR Teams Built With Reps Averaging 7 Years Experience
SalesRoads is headquartered in Boca Raton, Florida, and has operated for more than 19 years. The company says it has built more than 500 outsourced SDR teams, and that its SDRs average seven years of sales and appointment setting experience. That seniority is the main reason it ranks high: many SDR vendors staff programs with entry-level reps.
Each program includes dedicated SDRs plus a client strategist, an SDR performance coach, a research and data team, and an optimization specialist. SalesRoads also says it invests three times the industry standard in rep training. Clients can choose US-only or international calling regions. Named case studies include AchieveIt, where SalesRoads reports 27 million USD in total pipeline generated, InnSure at 170 appointments set and Copperweld at 225+ opportunities created.
SalesRoads is open about price: its site says programs start around 12,000 USD per month and scale with team size. That is above the low end of the market, which reflects the experience level and management layer included.
Best for: Companies with complex or higher-value offers that need experienced, phone-capable SDRs rather than junior reps.
Sales Focus Inc was launched in 1998 by founder, president and CEO Tony Horwath, and it runs a sales center in North Charleston, South Carolina. The company says it has served more than 1,200 businesses and hired more than 12,000 SDRs since it began.
Its SDR as a service model is strict about dedication and employment: every SDR works only on one client’s accounts, and every rep is a W-2 employee who is background-checked and drug-tested. That matters for buyers in regulated industries or those uneasy about contractor reps representing their brand. Sales Focus guarantees a team is live within 45 days, and it gives reps access to a B2B database of more than 35 million companies and 60 million contacts.
Sales Focus also runs outsourced outside sales and inside sales programs, so it can extend beyond appointment setting if you later want reps who carry a quota. The company reports more than 1.2 billion USD in gross revenue generated for clients.
Best for: Buyers who want fully dedicated, employee-based SDRs and a firm launch timeline.
4. Martal Group — Onshore Senior SDR Teams For B2B Tech Across North America And Europe
Martal Group has offices in Oakville, Ontario; San Francisco, California; Uniondale, New York; and Clermont-Ferrand, France. It says it has more than 200 onshore sales executives, distributed roughly 60% in the US, 20% in Canada, 10% in the EU and 10% in Latin America, and it positions them as mid-level and senior B2B sales talent rather than entry-level reps.
Buyers choose between a fractional sales team, a full-time dedicated team that Martal hires, trains and manages, or an enterprise sales team. Service tiers run from lead generation (lists, campaigns, outbound calls and qualified leads into your CRM) to tiers that add deal support, closing, onboarding and account management. Martal describes a typical monthly funnel of 3,000 to 5,000 prospects targeted, 9,000 to 12,000 emails and 250 to 450 calls.
Client logos on its site include Bosch and Zoho, and one financial services case study reports 880 booked meetings over 24 months. The EU presence makes it one of the stronger options for tech firms selling into both North America and Europe.
Best for: B2B software and technology companies that want experienced, onshore SDRs in multiple regions.
5. Televerde — SDR Outsourcing And Augmentation For Enterprise Tech Since 1995
Televerde was founded in 1995 and is headquartered in Phoenix, Arizona, according to its private equity owner, Main Street Capital. It runs delivery centers in Goodyear and Phoenix, Arizona; Madison and Rockville, Indiana; Córdoba, Argentina; and Glasgow, Scotland. Its customers have included enterprise technology companies such as SAP and Cisco.
Televerde offers two SDR models: full SDR outsourcing, where its team owns sales development, and SDR augmentation, where its reps add capacity alongside your existing team. Its business development reps identify, qualify and develop leads through the early and middle stages of the pipeline, using account-based insights for targeting. The company also supports customer retention and channel programs.
Televerde holds G2 Leader badges for lead generation services and displays an ISO/IEC 27001:2022 certification, which helps with enterprise security reviews. It also commissioned a Forrester Total Economic Impact study, published in November 2024, which buyers can read when building an internal business case.
Best for: Enterprise technology vendors running ABM programs that need SDR capacity with strong security credentials.
6. CIENCE — Outbound, Inbound And Local SDR Teams Backed By Its Own Data
CIENCE was founded in 2015 and is headquartered in Denver, Colorado, with additional offices listed in Kyiv and Guadalajara. It says it has served more than 2,500 B2B clients. Its SDR offering covers outbound and inbound SDR teams, scaled outbound, local SDRs and inside sales, and it combines those reps with its own B2B contact data.
CIENCE says a single SDR typically books 5 to 20+ qualified meetings a month depending on industry and target. Published examples include SendBird at 227 appointments in four months and Mandolin at 110 qualified meetings in six months. Pricing is a fixed monthly fee plus a commission for each held meeting, with month-to-month terms.
The breadth of models is useful if you need to add inbound lead response or local-market reps alongside outbound. Reviews on Clutch are more mixed than for some smaller providers, so check references in your segment before signing.
Best for: Companies that want flexible SDR capacity across outbound and inbound with data included.
7. Belkins — Dedicated SDR Supported By Researcher, RevOps And Deliverability Specialists
Belkins has run outbound programs since 2017 and lists Denver, Colorado, as its headquarters on Clutch. Its outsourced SDR service gives each client a dedicated SDR backed by a lead researcher, content strategist, RevOps expert, deliverability team, project manager, account director and HubSpot specialist.
That support pod is the main differentiator. Instead of a lone rep, the SDR works with specialists who build lists, write sequences and protect sender reputation. Belkins says starter programs average from 5,000 USD, with the starter tier covering about 1,500 leads a month across three outreach channels. It targets 20+ qualified meetings a month and says first meetings typically arrive within 30 to 45 days.
Belkins is especially strong when email is the primary channel, since it also sells cold email and deliverability services. Teams that need heavy phone work may prefer a phone-first provider.
Best for: Mid-market B2B companies that want a dedicated SDR with full research and deliverability support.
8. LevelUp Leads — Fractional And Full-Service SDRs With Cold Calling At The Core
LevelUp Leads is based in California and runs as a fully remote team serving clients globally. It offers fractional SDR and full-service outsourced SDR programs, with cold calling as the core channel and email, LinkedIn, list building and GTM strategy alongside.
Its reps are native English speakers working in the client’s time zone, and onboarding takes 10 to 14 days at no charge. The company reports more than 1,000 clients served and 5,100+ meetings booked annually, with case studies such as CoreVest at 224 meetings and 10 million USD+ in pipeline, and Site 20/20 at 240 meetings. It holds 5.0 ratings on both Clutch and G2.
The fractional option is the reason it earns a place here. Companies that cannot justify a full-time outsourced SDR can buy part of one, test the channel, then scale to a dedicated rep once it works.
Best for: Mid-market teams that want phone-led outbound and the option to start with a fractional SDR.
9. Launch Leads — Dedicated Reps For Outbound, Lead Qualification And Dead Lead Revival
Launch Leads was founded in 2009 and is headquartered in Salt Lake City, Utah. Its outsourced SDR service provides dedicated reps trained on a client’s category and offer, working as an extension of the client’s sales team. The company emphasizes human selling supported by technology rather than automated outreach.
Beyond outbound appointment setting, Launch Leads handles lead qualification, rapid inbound lead response, lead nurturing and dead lead revival. That makes it a good fit for companies sitting on a large CRM database of stale leads that never got proper follow-up. It reports more than 152,000 appointments set over its history.
Pricing is a monthly retainer based on campaign scope and target volume, not pay per lead, and a written scope and quote follow a free needs assessment.
Best for: Companies that want SDRs to work both new outbound and existing inbound or aged leads.
Strategic Sales and Marketing (SSM) was founded in 1989 by Al Davidson and is based in Farmington, Connecticut. It runs a US-based calling center staffed by its own employees, with no subcontracting, and says its reps are typically 35 to 55 years old. That older, experienced rep profile suits buyers selling to senior decision makers in traditional industries.
SSM’s services include appointment setting, inbound lead qualification, B2B lead management and nurturing, and major account lead generation. It focuses on sectors such as manufacturing, managed IT services, software resellers, ERP solutions and insurance. The firm says it has generated more than 3 million B2B sales leads since 1989.
On Clutch, SSM holds a 4.7 rating from 22 reviews, with reviewers describing scripted outbound calling, follow-up until a meeting is booked, and dashboards for tracking activity. It is a phone-first shop, so pair it with another partner if you need email-heavy outbound.
Best for: Industrial, IT services and insurance companies that want experienced US callers working major accounts.
How To Choose An Outsourced SDR Company
Will The SDRs Be Dedicated To Your Account?
Some providers assign reps who work only on your program. Others run pooled teams that split time across clients. Dedicated reps learn your product faster and represent your brand more consistently, so ask how many clients each rep supports and whether you can meet them before launch.
Who Manages And Coaches The Reps?
SDR performance depends on daily coaching. Find out who runs call reviews, how often scripts and sequences are updated, and who your main point of contact is. A provider that includes a strategist or performance coach takes management load off your sales leaders.
Where Are The Reps Located And How Are They Employed?
Onshore reps cost more but usually perform better on calls to senior buyers in the same market. Employment status also matters: W-2 employees are easier to vet and manage than contractors. Ask about location, language coverage, background checks and turnover rates.
Will They Work Inside Your CRM?
Embedded SDRs should log activity in your CRM, not a vendor portal you cannot access later. That keeps your data clean and makes handoffs to AEs smoother. If you are still choosing a CRM, our comparison of HubSpot vs Salesforce can help.
What Is The Commitment And Ramp Time?
Outsourced SDR programs usually take 30 to 45 days to launch and another few months to reach steady output. Ask for a written ramp plan, the minimum term, and what happens if targets are missed. Prefer providers that let you scale reps up or down after the first term.
Frequently Asked Questions
How Much Does SDR Outsourcing Cost?
Pricing varies by rep seniority, location and support staff. Among firms that publish figures, Belkins starter programs average from 5,000 USD per month and SalesRoads programs start around 12,000 USD per month. Most providers quote per dedicated rep or per team, sometimes with a per-meeting commission on top.
What Is The Difference Between An Outsourced SDR And An Appointment Setter?
An outsourced SDR is a dedicated rep who works as part of your team, prospects your accounts across several channels and qualifies interest before handing off. Appointment setting services focus on the output, booked meetings, and may use shared reps. Our guide on finding the right appointment setting company explains when that simpler model makes sense.
Can I Hire The Outsourced SDRs Later?
Some providers allow it. memoryBlue, for example, offers an audition-to-hire model. Ask about conversion fees and timing upfront, since many contracts restrict hiring vendor staff without an agreed fee.
Should Outsourced SDRs Use AI Tools?
Most providers now use AI for research, personalization and reply sorting, but the reps still handle conversations. If you want AI to make calls, our roundup of outbound AI call companies covers that separate category.
How Many Outsourced SDRs Should I Start With?
Most companies start with one or two dedicated SDRs on a single segment or region. That is enough to test messaging, measure meeting quality and see how your AEs handle the handoff. Add reps once conversion from meeting to opportunity is stable, rather than scaling volume before you know the leads are closing.
Conclusion
The best outsourced SDR companies in 2027 give you dedicated reps, a clear management structure and data that stays in your CRM. memoryBlue and SalesRoads lead for experience and depth, Sales Focus Inc stands out for W-2 employee reps, Martal Group and Televerde suit tech companies selling across regions, and LevelUp Leads offers a lower-commitment fractional entry point.
Shortlist providers whose rep location, seniority and channel mix match your buyers, meet the reps who will run your program, and agree on a written ramp plan before launch. If you are also deciding how cold email fits into the mix, our list of cold email agencies is a useful companion.
