Best outsourced SDR companies in the USA (2026): the published facts, side by side
Nine providers US companies shortlist for outsourced sales development, compared on what they publish: who does the work, where, what it costs, the commitment, how fast you start and the proof they show. We include ourselves on the same terms. "Not published" means exactly that.

How to read the table
Three models, three different things you are buying
Agency
You buy a campaign
The agency's reps run outreach for you, often across several clients at once. Fast to switch on, priced per month or per meeting, and you rarely keep the people or the system. Strongest when you need phone-heavy US callers and can pay US rates.
Marketplace
You buy a person
An offshore staffing platform recruits one rep you then manage yourself. Cheapest seat on paper; the recruiting, coaching, QA, devices and backup power become your job in a country you may not know.
X77 pod
You buy a run team
Dedicated SDRs who work only for you, inside your CRM, with a working team lead in the pod, AI doing the research and drafting, weekly numbers, a monthly board-ready pack and a former listed-company CEO accountable for the result. Live in 7 days. Full model comparison.
Buyer questions
Choosing an outsourced SDR partner
Which outsourced SDR company is best for a US company in 2026?
It depends on the constraint you are solving. If you must have US-based callers and can pay $10,000–$17,000 a month per SDR, SalesHive and SalesRoads publish that model. If you want scale across many languages, memoryBlue and Callbox are the largest. If you want dedicated people who work only for you, inside your CRM, at 60–70% below a US seat, with an executive accountable for the number, that is the X77 pod model. The table above gives the published facts for each so you can compare like for like.
How much does outsourced SDR cost in the US?
Published US prices in 2026 run from roughly $2,000 a month for email-only managed outbound to $11,950–$16,750 per four-week cycle for one or two US-based SDRs. Most agencies do not publish prices. X77 quotes each pod in writing within 24 hours of a 20-minute scoping call; we do not publish a price list because every pod is scoped to a specific outcome, role mix and hours.
Is an offshore SDR team as good as a US-based one?
For research, list building, sequencing, inbound qualification and most outbound email and LinkedIn work, a well-run offshore team on US hours performs at parity at a fraction of the cost. For cold calling into senior US buyers, accent, hours and coaching matter more than passport: Cape Town's neutral English accent and Eastern-time overlap is why we lead with it. What makes the difference is the management layer — a team lead inside the pod, QA scoring and an executive who owns the number.
Do outsourced SDR companies guarantee meetings?
Almost none do, and the honest ones say so. Meetings depend on your market, offer and list as much as on the reps. X77 commits to what we control: seats live in 7 days, agreed daily activity and quality scores, a weekly KPI report, a monthly board-ready review, and replacement at no cost of any seat that misses target after ramp.
What should I ask any outsourced SDR vendor before signing?
Who exactly does the work and are they shared across clients? Who manages them day to day and how often do you see numbers? What happens if a rep under-performs? Who owns the lists, domains, sequences and data when it ends? What is the real start date and what is the minimum term? Can I speak to the executive accountable for my account? Every one of those answers is on this site for X77.
