Partnerships and co-selling for Series B companies: scaling without breaking for B2B SaaS in the DACH region

This edition of the Growth Broker playbook is written for founders and revenue leaders at Series A–C B2B SaaS companies 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 partnerships and co-selling has to be shaped to that reality from day one.

Series B is the stress test for partnerships and co-selling. 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, sourced and influenced pipeline from partners, 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 B2B SaaS, the binding constraint is almost always efficient growth under a fixed CAC ceiling, and in the DACH region it is compounded by the fact that trust-building cycle length, not intent is what actually gates growth. Partnerships and co-selling 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 partnerships and co-selling is signing MOUs no one operationalises, amplified by headcount. Fix the root cause; do not paper over it with more people.

Compensation begins to matter now. Pay operators on sourced and influenced pipeline from partners outcomes, not on effort. Effort-based comp at Series B produces theatre.

A well-run partnerships and co-selling 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 B2B SaaS in the DACH region: the SaaS teams that install this early compound category leadership inside 18 months, and one properly-run DACH account survives leadership changes and compounds for years. That is the reason it is worth installing partnerships and co-selling deliberately for this market rather than importing a playbook designed for somewhere else.
