Discovery calls: a case study playbook for marketing and creative agencies in the DACH region

This edition of the Growth Broker playbook is written for agency owners and heads of new business operating in the DACH region. In this market, DACH buyers reward rigour, documentation, and long-cycle trust — not urgency-led campaigns, so the way you install discovery calls has to be shaped to that reality from day one.

Names removed, numbers preserved. This is a real discovery calls engagement, reproduced as a playbook. Client had product-market fit, a rev team of eleven, and a stalled pipeline.

Week one: diagnosis. The stated problem was "not enough leads". The actual problem was reading a script instead of running a diagnosis, which had been masked by inbound velocity that peaked two quarters earlier.

Weeks two to three: rebuild the target list from scratch and re-cut the trigger. Discovery calls works when everything after discovery is downstream of what you learned in it; the client had drifted away from that first principle.

Inside marketing and creative agencies, the binding constraint is almost always owner-time bottleneck on the sales function, and in the DACH region it is compounded by the fact that trust-building cycle length, not intent is what actually gates growth. Discovery calls is only useful here when it is pointed at both constraints at once.

Weeks four to six: live at 20% of previous volume, quality bar raised. Discovery-to-opportunity conversion moved every week, though absolute numbers stayed modest.

Weeks seven to twelve: ramp. By week ten the number was ahead of the pre-stall baseline. By week twelve it was 40% ahead. Cost per outcome was roughly halved.

What we would repeat: the diagnosis step, the quality bar, and the weekly review. What we would kill sooner: two tools we bought in month one that added noise instead of leverage.

The client's own summary at the end of quarter one: "we thought we needed more of everything; we actually needed less of the wrong things." That is usually the lesson.

Concretely for marketing and creative agencies in the DACH region: agencies that install this stop trading time for pipeline and start productising it, and one properly-run DACH account survives leadership changes and compounds for years. That is the reason it is worth installing discovery calls deliberately for this market rather than importing a playbook designed for somewhere else.
