$120K SDR Hire
Hiring an SDR costs $8–12K/month all-in, takes 3–6 months to ramp, and 55% miss quota in the first six. We replace that gamble with a fully-built outbound team — lists, copy, infrastructure, multi-channel outreach, reply handling, qualification — at a fraction of the cost.
Why Outsource
The In-House SDR Math Doesn't Work for Most Companies
The standard advice is "hire an SDR." But the standard SDR hire costs $8–12K/month all-in once you stack base salary ($55–75K), commission, tools ($500–1,500/mo), management overhead (~10 hrs/week), and recruiting fees amortised over a 14-month average tenure. They miss quota 55% of the time in their first six months. They quit at a 35%+ annual rate.
That's a $96–144K annual bet on a single rep — and you absorb every dollar of ramp risk, every recruitment cycle, every tool subscription, and every "it's not working" meeting before you have any real pipeline.
An outsourced SDR team flips the math. The agency owns the ramp, the infrastructure, the playbook, and the talent pool. You just pay for the output: qualified meetings on your calendar.
You Should Outsource SDRs If:
- You need pipeline in weeks, not quarters
- You've burned 1+ SDR hires that didn't ramp
- You don't have a dedicated sales manager to coach a SDR
- You're testing a new ICP, market, or offer before committing headcount
- Your founder or AEs are still doing prospecting
- You want multi-channel coverage without hiring 3 specialists

How It Works
What Your Outsourced SDR Team Actually Does
ICP Definition
Industry, company size, title, geography, buying triggers. We define your exact target with surgical precision and validate it against your best existing customers.
Prospect List Building
Verified contact data sourced via Apollo, LinkedIn Sales Navigator, and Clay — segmented by ICP layer so every message is relevant to the recipient.
Sequence & Copywriting
Custom cold email, LinkedIn DM, and cold-call sequences written for your ICP. No mass templates. Every line is built to earn a reply, not impress a copywriter.
Infrastructure & Deliverability
Dedicated sending domains, properly warmed inboxes, SPF/DKIM/DMARC setup, and inbox rotation — so emails land in primary inboxes, not spam.
Multi-Channel Sending
Email + LinkedIn + cold calling, sequenced together so prospects see your name across multiple channels. Familiarity compresses the sales cycle.
Reply Handling & Qualification
Every interested reply goes through a qualification step before booking. You only get on calls with prospects who match your ICP and have a real reason to talk.
Weekly Reporting
Open rates, reply rates, meeting rates, and pipeline value — reviewed weekly so you always know what's working and where we're optimising.
Continuous Optimisation
Every campaign generates data. We run 3–5 message variations simultaneously and double down on what produces meetings — month after month.
Buyer's Guide
How to Pick a Good Outsourced SDR Agency
Most outsourced SDR engagements fail for predictable reasons. Use these filters before signing with any agency.
They Specialise in B2B Outbound — Not Generic "Sales as a Service"
Avoid call-center operations that lump cold calling, customer support, and back-office work together. You want a team that lives and breathes B2B outbound — they've sent millions of emails and run thousands of campaigns. Generic shops can't compete on craft.
They Insist on Defining Your ICP Before Building Lists
If an agency starts running campaigns within 7 days, run. Real outbound starts with ICP definition, list segmentation, and sequence design. Anyone skipping that step is delivering volume, not pipeline.
They Manage Their Own Sending Infrastructure
Sending from your primary domain is how you torch your sender reputation. A real agency uses dedicated domains, manages warming, and handles deliverability themselves — so the worst-case is they replace a domain, not your business email getting blacklisted.
They Show You Real Pipeline — Not "Activity Reports"
Beware of dashboards full of emails-sent and meetings-attempted. The only metrics that matter are qualified meetings booked, show rate, and pipeline value generated. Insist on those metrics in the contract.
They Have Case Studies in Your Industry or Deal Size
What works for $99/mo SaaS does not work for a $50K consulting engagement. Demand to see results from clients with similar ICPs, deal sizes, and sales cycles to yours. Generic "we work with everyone" is a red flag.
You Own the Data and the Sequences
If the agency disappears, you should walk away with your prospect list, your campaign sequences, and your performance data. Read the contract. If they retain everything, you're renting a pipeline rather than building one.

FAQ
Outsourced SDR Questions
What is an outsourced SDR?
An outsourced SDR (Sales Development Representative) is a contracted team — usually inside a specialized agency — that runs the top-of-funnel prospecting work an in-house SDR would do: building target lists, sending cold emails and LinkedIn messages, making cold calls, qualifying replies, and booking meetings on your team's calendar. Instead of hiring, training, and managing a single SDR yourself, you pay an agency for the full output.
How much does an outsourced SDR cost?
Most outsourced SDR engagements cost $3,500–$7,500/month, depending on volume, channels, and qualification depth. By comparison, an in-house SDR typically costs $8,000–$12,000/month all-in once you include base salary ($55–75K), benefits, tools ($500–$1,500/mo), management overhead, and recruiting fees amortised over their tenure.
Why does outsourcing fail for some companies?
Three reasons: (1) the company hadn't validated their ICP or offer before engaging — agencies need a clear target to be effective; (2) the engagement was treated as fully hands-off when monthly strategy alignment is required; (3) the agency was a generic call-center operation rather than a specialist matched to the company's deal size and industry. We screen out all three of these with a structured 30-day onboarding.
When should we outsource SDRs vs hire in-house?
Outsource when: you need pipeline now, you're testing a new ICP/market, you've already burned a SDR hire that didn't work, or you don't have a dedicated sales manager to coach an in-house SDR. Hire in-house when: you have 6+ month sales cycles requiring deep relationships, your industry needs deep credentialing, or you have RevOps maturity to coach a team of 3+ SDRs.
How quickly can we start booking meetings?
Most clients book their first qualified meetings within 2–4 weeks of campaign launch. The first 30 days handle ICP definition, list building, sequence writing, and infrastructure setup. By weeks 4–8 most engagements are at full sending volume with consistent meeting flow.
Do you replace our existing sales team?
No. Outsourced SDRs sit at the top of your funnel — they generate qualified meetings and hand prospects off to your account executives or to you (if you're founder-led). Your closers stay closers. We just remove the prospecting bottleneck.
What's included in your outsourced SDR service?
ICP definition, prospect list building (verified data via Apollo, Sales Navigator, Clay), email sending infrastructure (dedicated domains, warming, deliverability), copy for cold email + LinkedIn + calling, multi-channel sequence orchestration, reply handling, meeting qualification, weekly performance reporting, and continuous campaign optimisation.
What if we already have an SDR? Can you complement them?
Yes. Many growth-stage clients run an outsourced SDR team alongside their in-house SDRs — typically with the agency handling cold outreach (volume) while in-house focuses on inbound qualification, account-based outreach to enterprise targets, or post-event follow-up. Speak to us about a hybrid setup.
