Discovery calls for Series B companies: scaling without breaking for professional services firms in the DACH region

This edition of the Growth Broker playbook is written for managing partners and heads of business development at consultancies and agencies 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.

Series B is the stress test for discovery calls. What worked at fifteen people fails at fifty unless the operating rhythm is deliberate.

The Series B move is to separate the model owner from the operators. One senior human owns strategy, discovery-to-opportunity conversion, and the weekly review; a small team runs the machine.

Add a second geography or segment only when the first one is producing a defensible number for two full quarters. Not before.

Inside professional services firms, the binding constraint is almost always senior partner time, not lead volume, 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.

Governance appears at Series B — that is fine, provided it accelerates rather than slows. The test is whether reviews still make decisions or just distribute updates.

The Series B failure mode of discovery calls is reading a script instead of running a diagnosis, amplified by headcount. Fix the root cause; do not paper over it with more people.

Compensation begins to matter now. Pay operators on discovery-to-opportunity conversion outcomes, not on effort. Effort-based comp at Series B produces theatre.

A well-run discovery calls function at Series B is the moat that survives to Series C. Companies that skip this discipline burn through raises trying to buy it back.

Concretely for professional services firms in the DACH region: one signed retainer typically funds the entire growth program for a year, 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.
