One hands you software and leaves the motion to you. The other hands you volume and leaves the brand risk to you. Here's the honest comparison — including where we lose.
Signal-based, not spray-and-pray: SDR.ai reaches out only to signals — yours (inbound) or ours (intent from the web and our partners). Never cold lists.

Start here
"AI SDR" and "SDR agency" get compared as though you're picking between two versions of the same thing. You aren't. You're choosing what you want to own — and what you want someone else to be accountable for.
An AI SDR platform builds lists, writes sequences, and sends at scale. Some now handle replies and booking. The AI does the work of a rep — but nobody on the vendor's side is accountable for whether meetings actually land.
Typically $250 – $2,000/mo · you supply the operator
An outsourced SDR agency assigns you reps who prospect on your behalf. They own the process end to end and report meetings booked. The people are real — but they may be shared across accounts or new to your category.
Typically $5,000 – $12,000/mo · 6–12 month contracts

The comparison
The third column is us. We put it here so you can hold it to the same standard — and so you can see plainly where the other two models beat us.
| AI SDR software | SDR agency | SDR.ai (hybrid) | |
|---|---|---|---|
| Who runs it day to day | You. The tool is only as good as the person operating it. | Their reps — sometimes shared across several clients. | One named SDR on your account, augmented by AI. |
| Time to first meeting | Days — if you already know what to say. | 4–8 weeks, after onboarding and rep ramp. | Live in days. Week 1 targeting, week 2 the motion runs. |
| Does anyone dial? | Usually not — most are email and social only. | Yes — manually, which caps volume. | Yes. AI-Dialer runs up to 125 dials a day per SDR. |
| Who owns the brand risk | You — it's your domain being burned. | Them, in theory. You, in practice. | Shared. You approve every sequence before it ships. |
| Accountable for meetings | Nobody. The software has no quota. | Yes — that's what you're paying for. | Yes. Judged on the calendar at day 90. |
| Lock-in | Low. Cancel any month. | High. 6–12 month contracts are standard. | 90-day pilot. No long-term contract. |
| Where it breaks | Nobody operates it, so it quietly stops working. | Rep churn resets your institutional knowledge. | Needs a real ICP. If you can't name your buyer, we can't help. |

The honest part
Most vendor comparison pages are a rigged fight. This one isn't. There are real situations where an AI SDR tool or a traditional agency is the better call — and if you're in one of them, we'd rather you knew now.
The gap nobody's filling
Look closely at the two models and the same hole appears in both — from opposite directions.
Autonomous agents are good at getting attention and bad at what happens next. The moment a prospect asks something real, there's nobody there — and the thread dies.
A rep dialing manually gets through a fraction of the list. That's not a work-ethic problem. It's an arithmetic one, and no amount of coaching fixes it.
AI does the volume — targeting, sequencing, dialing. The human does the part that requires being a person: the conversation that turns interest into a meeting.
One SDR. Ten AI-powered LinkedIn accounts. Up to 125 dials a day. The AI finds who's in-market inside your ICP, opens the conversation on the channel your buyers actually read, and warms the connection. Then a real person picks up the phone — and by then, the call isn't cold.
Across a 90-day pilot that runs to roughly 15,000 connection requests to your ICP and 750+ real conversations opened — landing up to 20 qualified meetings a month from a single SDR.*
The math
Cost per qualified meeting is the only number that survives a board meeting. Here's how the three models compare on it.
Cheapest per seat, unpredictable per meeting. A few hundred dollars a month buys the tool. It does not buy an operator, and the cost per meeting swings wildly depending on whether anyone is actually running it.
$1,200+ per qualified meeting. Four SDRs run $360K+ a year fully loaded, take six months to ramp, and often churn before they get there. Your window between rounds is shorter than their ramp time.
Roughly $350 per qualified meeting. $7,000/mo plus a $2,500 setup, no long-term contract — and live in days rather than quarters.*
Why take our word for it
Most comparison pages on this topic are written by content teams who have never carried a quota. This one isn't.
SDR.ai is founder-run by Chad Burmeister, who wrote the books on AI for Sales — literally — and has spent a career building and running AI-powered sales teams. The model described on this page is the playbook refined across those teams, now pointed at your ICP.
"…significant impact on our business — ~$.5B high quality PipeGen."

That's also why this page tells you when not to hire us. An operator who has actually run the motion knows exactly where it doesn't fit — and pretending otherwise just wastes a discovery call we both have to sit through.
Questions buyers actually ask
The discovery call
Thirty minutes. We map the model to your actual accounts — profiles, sequences, dial math — and show you what 90 days of pipeline looks like before you spend a dollar. If an AI tool or a traditional agency is the better fit for you, we'll say so on the call.
