Best SDR as a Service Companies in 2026: 9 Providers Compared by Model, Price and Risk

Five criteria. Model: whether you are buying a person, a program, or a meeting, which determines who carries the risk of a bad month. Price transparency: whether the vendor publishes rates or makes you sit through a discovery call to learn them; publishing is a signal of confidence. Rep location and dedication: US, nearshore or offshore, and whether the rep is yours or shared. Contract terms: minimum term, exit clauses, and what happens when a rep is replaced. And meeting definition: whether 'qualified' is written down and whether payment depends on the meeting being held. We did not rank on review scores, which in this category are gamed on all sides.

Belkins is the name most buyers encounter first, a large appointment-setting agency with a globally distributed team and a heavy emphasis on email deliverability and research-led targeting. The model is a managed program on a retainer, priced by custom quote rather than a public rate card, with pricing that reported benchmarks place in the mainstream $5,000 to $10,000-a-month band for a single-rep program. The strengths are process maturity and the depth of the deliverability tooling; the weaknesses are the retainer structure, which means a slow month costs the same as a good one, and minimum terms that typically run three months or more. Best for mid-market companies with a proven email message that want a reliable, well-run cold program. We compare the two models directly in Belkins vs Bountii.

SalesHive is one of the few large providers that publishes prices: US-based tiers from $7,000 to $12,000 a month and offshore tiers from $4,500 as of September 2026, on month-to-month terms rather than long minimums. The program combines cold calling with email and LinkedIn on the company's own platform, and the month-to-month structure is a genuine differentiator in a category that loves six-month lock-ins. The trade-off is that you are still buying a retainer, so cost per meeting swings with results, and the top tier is expensive if your segment does not answer the phone. Best for companies whose buyers respond to calls and who value the ability to cancel. Full comparison in SalesHive vs Bountii.

Martal Group is a Canadian-headquartered provider with a global team that specialises in technology and SaaS sales cycles. The distinguishing feature is flexibility of model: alongside the standard managed retainer, Martal offers a pay-per-meeting structure, which aligns incentives in a way most agencies on this list do not. Pricing is by quote; reported benchmarks place the retainer in the middle of the market. Strengths are tech-sector fluency and the option to move risk onto the provider; the usual caveats about shared versus dedicated reps and offshore communication overhead apply. Best for B2B software companies that want an agency but refuse to pay a pure retainer.

CIENCE built one of the largest research-plus-outbound operations in the category, with a strong reputation for data quality and multi-channel campaigns. In 2026 its assets moved to graph8, and the offering has been repositioned around that platform. We include it because buyers still search for it, but the practical advice is to verify exactly what you are contracting for, who employs the reps, and what the terms are today, rather than relying on anything written before the transition. Best for companies already on the graph8 stack; others should treat it as a new vendor and diligence it accordingly.

memoryBlue occupies the premium end of the US market: reps based in the United States, trained in-house, working dedicated programs, at prices that sit above the offshore-staffed competitors. The distinctive feature is the path to bring the rep onto your own payroll after a period of outsourced work, which turns the engagement into an extended, de-risked hiring process. That is genuinely valuable if you plan to build an in-house team and want to see reps perform on your product before committing. Best for companies that intend to hire SDRs within a year and want a try-before-you-buy route; expensive if you simply want meetings.

Callbox is one of the longest-established lead generation and appointment-setting firms, with large delivery teams in Asia and a client base that spans the US, APAC and Europe. The model is a managed, account-based program across phone, email, LinkedIn and web, priced by quote. Its scale and multi-region coverage make it a common choice for companies that need outreach in several time zones at once; the trade-offs are the offshore delivery model and a process built for volume rather than high-touch executive access. Best for companies running broad campaigns across regions with clear, repeatable messaging.

Leadium runs managed outbound programs with a blended team and is unusually willing to publish detailed cost guides for the category, which makes it easier to diligence than most. The model is a retainer with program management included, priced by quote within the mainstream band. Strengths are transparency and a data-first approach to targeting; the weaknesses are the ones shared by every retainer program, namely that you pay for activity and carry the risk of the activity not converting. Best for companies that want a managed program from a vendor that will show its working.

HireSDRs is a different product from the seven above: a staffing marketplace, not a managed program. You hire a vetted, mostly Latin American remote SDR at $1,999 a month full time or $999 part time as of September 2026, on month-to-month terms, hired in a day or two, with the contractor-of-record paperwork bundled. You manage the rep, supply the tools and the playbook, and own the results. That makes it the cheapest seat on this list by a wide margin and the one that demands the most from you. Best for companies with an existing sales playbook and a manager with capacity, who want a rep without recruiting overhead. We compare it with the marketplace model in HireSDRs vs Bountii.

Bountii is not an SDR provider, and we list it because buyers comparing SDR as a Service are usually trying to solve the same problem: more qualified first meetings without hiring. Bountii solves it by pricing the meeting rather than the outreach. A company posts a bounty naming its target accounts and titles and the price it will pay per qualified meeting, from $200; independent sellers with a real relationship to those buyers, called hunters, claim the bounty and make a warm introduction; the company confirms the held meeting met the written criteria and the bounty is released, 100 percent of it to the hunter. The company pays a subscription of $199 a month for ten target accounts or $499 for thirty, and nothing for meetings that do not qualify.

The strengths are the risk profile (a zero-meeting month costs the subscription and nothing else), the channel (warm intros convert markedly better than cold sequences, particularly with senior buyers), and the absence of ramp, minimum terms and shared reps. The honest limits: volume depends on how many hunters have paths into your accounts, so it is strongest for named-account and executive targeting rather than thousand-contact blasts; it is not a substitute for a high-volume mid-market cold program, and companies often run it alongside one. If that fits your list, book a demo. Glencoco offers a different take on pay-per-meeting, with cold-calling contractors rather than warm intros; the comparison is in Glencoco vs Bountii.

If your buyers answer cold email and you want a mature, well-instrumented program: Belkins or Leadium. If they answer the phone and you want to be able to cancel: SalesHive. If you are a tech company that wants an agency but not a pure retainer: Martal. If you plan to hire in-house within a year and want to audition reps first: memoryBlue. If you need coverage across regions at volume: Callbox. If you have a playbook and a manager and want the cheapest seat: HireSDRs. If your targets are named accounts and senior titles, or you simply refuse to pay for activity: Bountii. And whichever you pick, write the qualified-meeting definition into the contract and price every option per held meeting, not per month; the maths is in SDR as a Service Pricing in 2026.
