You did the joint webinar. Both logos on the invite, both teams promoting it, a genuinely decent session.
Twelve people showed up. Four were internal. Nobody followed up.
Everyone agrees it was a good first step, nobody wants to say it produced nothing, and six months later somebody suggests another webinar.
Co-marketing fails in a specific and repeatable way, and it is almost never the content’s fault.
Nobody Agreed What It Was For
Ask both sides what success looks like before the campaign and you will get two different answers. Yours is pipeline. Theirs is often visibility, or keeping a vendor relationship warm, or a marketing manager hitting an activity target.
Neither answer is wrong. But if you never surface the gap, you build one campaign trying to serve two goals and it serves neither.
The fix: agree one number before anything gets designed. Not “raise awareness.” A number: qualified conversations, registrations from a defined segment, sourced pipeline. Write it in the first email. If they will not commit to a number, that tells you what this campaign is going to be.
You Assumed the Audiences Overlap
This is the quiet killer. Two companies both selling to “enterprise IT” assume shared audience, then discover afterwards that yours are security architects and theirs are procurement.
The overlap is often much smaller than the org charts suggest, and you only find out after you have spent six weeks building.
The fix: test it in an hour. Both sides pull twenty target accounts and compare. Both sides name the exact job title. If the titles do not match, you do not have a co-marketing campaign, you have two campaigns sharing a landing page.
Nobody Owned the Follow-Up
The campaign has an owner. The follow-up does not.
Leads land in a shared spreadsheet. Your team assumes the partner will work them because they are the partner’s audience. The partner assumes you will because it is your product. Eleven days pass. The lead is cold and both companies conclude co-marketing does not work.
The fix: name the person, not the company, before launch. One human, on one side, who calls the list within forty-eight hours. Put their name in the plan.
You Built Content Nobody Asked For
Joint content tends to be about the partnership. “How Acme and Beta work together.” Nobody has that problem.
The buyer has a problem that happens to need both of you. That is a different piece of content, and it usually does not mention the integration until well past the halfway point.
The fix: write down the customer problem first, in one sentence, with no product names in it. If you cannot, there is no campaign here. That is a useful thing to learn in an hour rather than a quarter.
The Incentives Pointed Different Directions
Their rep gets paid on their product. Your campaign asks them to spend time on a conversation where your product is half the value.
Nobody says no. They just do not prioritise it, which looks identical to agreement right up until the deadline.
The fix: make sure the campaign produces something their reps want. Usually that is qualified conversations in accounts they already want, not brand exposure. If your campaign does not make their quarter easier, it will lose to whatever does.
What Working Co-Marketing Looks Like
Less exciting than the failed version, which is part of why it works.
- One agreed number, written down, before design starts.
- A tested audience overlap, not an assumed one.
- A named human owning follow-up on one side, with a deadline.
- Content about a customer problem, not about the partnership.
- Something in it that makes the partner’s reps money this quarter.
- A small first campaign, so you learn what works before you spend.
Note that four of the six are decided before anything gets created. Co-marketing is mostly an agreement problem wearing a content problem’s clothes.
One More Thing Worth Doing
Publish it publicly, and publish it well.
Joint content that is indexable does something a gated PDF never will: it creates independent corroboration of who you are and what you do. When your partner’s site, the joint session page and the write-up all describe you the same way, that consistency is what gets a company named when a buyer asks an assistant who solves their problem.
Most co-marketing gets locked behind a form and produces one list. The same work published openly compounds for years.
P.S. If your last joint campaign has no owner named in the plan, you already know how it went.
