# Co Marketing — Marketing Skill for AI Agents

The best co-marketing partner sells to the same buyer persona but solves a different problem and sits adjacent to you in the workflow — before, after, or alongside your tool — so you're complementary, not competitive. Find candidates by asking what tools your customers already use, checking account overlap in Crossbeam or Reveal, mining G2/Capterra category neighbors, and noting who sponsors the same newsletters and podcasts. Score each on audience fit, audience size, brand alignment, engagement quality, reciprocity potential, and ease of execution, then start with a low-effort format like a newsletter swap or co-authored post before committing to a bigger joint webinar or research report. Agree on lead handling, promotion commitments, and success metrics up front, and measure lead quality (MQL/SQL conversion), not just volume.

Subject: Acme + Beacon co-marketing idea

Hey Priya,

I'm head of marketing at Acme — we do marketing analytics for B2B teams.

I noticed we share a lot of the same audience: your CMS customers are exactly the marketers who ask us for content-performance reporting.

I have an idea for a joint webinar — "From publish to pipeline: measuring what your content actually drives" — that would work well for both our lists.

Open to a quick call to explore?

## FAQ

### Who makes a good co-marketing partner?

Someone who shares your buyer persona but solves a different problem and sits adjacent to you in the workflow — the tool your customers use right before or right after yours. They should be a similar company stage and customer size, have an audience worth reaching, and be a brand you'd be proud to associate with. Complementary beats competitive: you want to reach the same people without fighting over the same budget.

### How do I split leads from a joint webinar?

Decide before you run it and document it in a simple co-marketing agreement. Common splits: each partner keeps their own registrations (cleanest, but you lose cross-pollination), all leads shared between both (max reach, but needs a clear MQL/SQL handoff), or split by which list the signup came from. Whatever you choose, measure lead quality — MQL/SQL conversion rate and revenue attributed — not just raw signup count, and hold a post-campaign debrief to decide whether to do more together.

### How do I pick one partner when I have several options?

Score each candidate 1-5 on audience fit, audience size, brand alignment, engagement quality, reciprocity potential, and ease of execution, then weight by your current goal — if lead gen is the priority, weight audience fit and size higher; if it's relationship building, weight brand alignment and engagement. Favor partners with a partnerships team and a history of co-marketing, since they execute faster, and start with a low-effort content format to test the working relationship before a bigger commitment.
