Partnerships and co-selling: examples that actually work in 2026 for PE-backed portfolio companies

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.

Most articles on partnerships and co-selling are five years out of date. This one is not. Partnerships and co-selling in 2026 is using another company's distribution to reach buyers you cannot cost-effectively reach yourself, and the examples below are all inside the last four quarters.

Example one: a Series B infrastructure company applied partnerships and co-selling to a list of 340 accounts and moved sourced and influenced pipeline from partners from a baseline to a defensible weekly number inside seven weeks. What worked was ruthless focus on trigger quality.

Example two: a bootstrapped agency owner ran the same play at one-tenth the budget and produced enough qualified pipeline to hire two full-time operators. The lesson is that partnerships and co-selling scales down, not just up.

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.

Example three: an enterprise incumbent tried partnerships and co-selling across four regions in parallel and stalled — the exact pattern of signing MOUs no one operationalises. They restarted with one BU, hit the number in nine weeks, and then expanded.

The pattern across every winning example: they respect that one great partner is worth ten marketing hires, and they refuse to touch the model until they have a legible number on sourced and influenced pipeline from partners.

The pattern across every failing example: too many tools, too many stakeholders, no single owner. Fix that first and copy the plays.

If you take one thing from this list, it is that partnerships and co-selling is a discipline before it is a technology. The examples that work are all built on the same operating rhythm.

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.
