Case Study
$143 Per Booked Meeting.
A marketing agency replaced a $5-10K/mo SDR-or-agency line item with Vruum. Here is the cost-per-meeting math, the stage funnel, and the segment-level intelligence that came along for the ride.

The Setup
A marketing agency wanted to grow pipeline without standing up an in-house SDR team or signing a six-month agency contract. The trade-off most operators face: hire and wait three months for ramp, or pay an agency $5,000+/mo for a motion they cannot tune.
We ran the standard Vruum motion. A live operator plus the agent stack handling research, outreach, and reply triage on LinkedIn under the agency's name. The agency takes the meetings. We tested multiple ICPs in parallel and read the funnel together every week.
The Vendor-Swap Math
Three ways to put outbound meetings on the calendar. Pick where your dollars work hardest.
| Option | Cost | Ramp | Per Meeting |
|---|---|---|---|
| In-house junior BDR | $8-12K/mo loaded | 3-6 months | $1,400-5,250 |
| SDR-as-a-service agency | $5-10K/mo | 1-2 months | $500-2,000 |
| Vruum | Retainer + $1K per 800 prospects | Meetings in 30 days | $48-188 |
The bottom row is Vruum's published pricing. This engagement landed at $143 per booked meeting, well inside that published $48-188 range.

The Hidden Win: Segment Intelligence
The dollars also bought a calibrated map of where the offer actually lands.
Most outbound spend buys you contacts. Vruum buys you contacts plus the segment-level read on which ICPs convert. We tested four prospect segments in parallel and let the funnel tell us where to scale. Here is what the agency learned, for the price of zero MQLs from a $5K agency retainer.
Real Estate Team Owners
Scale43% follow-up reply rate. 4 of 7 total meetings. This is the wedge. Scale it.
Coaches (Executive / Life / Divorce)
Expand73% follow-up reply rate, the hottest segment per dollar tested. Expand sample next cycle.
Consultants
Hold33% acceptance, 31% follow-up reply. Steady mid-tier. Keep running, watch unit economics.
Insurance Agency Owners
PivotHigh volume, low conversion. We are pivoting this budget into Real Estate next cycle.
This is the part agencies and in-house SDRs do not give you. In-house reps spend a quarter learning what works. Outbound agencies are not paid to tell you which ICP to drop. Vruum shows you the table every week and pivots volume the following cycle.
The Takeaway
$143 per booked meeting on LinkedIn. A stage funnel that beats industry at every step. And a segment-by-segment read on where the next dollars should go. The same budget on an SDR would still be in ramp. The same budget on an agency would not come with the data.
