Partnerships and co-selling for agencies: how to productise the offering for PE-backed portfolio companies
The service design, pricing, and delivery model for running partnerships and co-selling as a productised offering inside a services firm. Written for operating partners and portfolio CEOs inside private equity.
This edition is written for operating partners and portfolio CEOs inside private equity. In PE-backed portfolio companies, PE-backed operators run on 90-day cycles and reward operating rigor over storytelling, so the way you install partnerships and co-selling has to reflect that reality from day one.
Partnerships and co-selling is one of the highest-margin offerings an agency can add in 2026. It is using another company's distribution to reach buyers you cannot cost-effectively reach yourself, and clients will pay a premium for the discipline they cannot install themselves.
Productise around outcome, not activity. Sell sourced and influenced pipeline from partners moving to a defined level in a defined window, not a monthly retainer of vague ops.
Delivery pod: one strategist, one operator, one editor. Fewer people than that risks quality; more than that dilutes margin.
The binding constraint we see in PE-backed portfolio companies is almost always predictable execution against a hold-period thesis. Partnerships and co-selling is only useful in this vertical when it is pointed at that constraint — not at a generic growth number borrowed from another category.
Onboarding takes two weeks: diagnosis, list build, trigger definition, kill criteria. Do not ship anything live before the diagnosis is signed off.
Pricing: outcome-linked base plus a monthly ops fee. The base rewards results; the ops fee funds the delivery pod.
Client failure mode: signing MOUs no one operationalises. Write it into the engagement letter as a shared risk, not something you absorb quietly.
The agencies making the most from partnerships and co-selling are the ones with the tightest playbook. Documented, versioned, and improved every quarter.
Concretely for PE-backed portfolio companies: the portfolio companies that install this hit the next value-creation milestone on schedule. That is the reason it is worth installing partnerships and co-selling properly rather than half-heartedly across three vendors.
