The problem with outbound today

Every channel is getting more expensive and less effective

Every channel is getting more expensive and less effective

Call centers have dismal economics

Outsourced SDRs cost $4–8k/month and book just 8–15 meetings at $300–600 each — before overhead.

Paid ads are in a cost spiral

B2B LinkedIn leads run $75–200 and Google $50–150, and that's just leads, not booked meetings.

Email open rates are collapsing

Email opens sit at 18–23% and replies at just 1–3% — and spam filters tighten every quarter

SDR agencies are unpredictable

Agencies take 4–8 weeks to ramp and charge $150–500 per booked meeting — quality you can't control
