The problem

Stackline sold retainers to growth-stage brands. A junior SDR, a list VA, and Apollo/Clay still left Jordan reviewing bad fits and chasing follow-ups. Meetings booked — but cost per qualified call was too high to scale.

What we ran in-house

Full pipeline department on turnkey tier: ICP Mapper, Scrape, Opener, Reply, Brief, Booking, Sequence, and Nurture agents — plus human calls on warm threads.

  • Weekly verified list refresh to Slack
  • Sequences and nurture on autopilot
  • Warm replies briefed before Jordan's closers dial
  • Human follow-up calls on interested leads

What changed

Jordan's calendar filled with qualified intros — not list reviews. The junior SDR role was cut. Tool spend dropped. One Slack channel became the entire outbound room.

"They run outbound. I run the agency. I only take meetings that are actually warm."

Results

22 qualified meetings in month one. Two retainers closed from pipeline sourced entirely through the turnkey room. Loaded cost vs prior SDR + tools: roughly $8–12K/mo saved.
