Co-marketing campaigns with partner agencies: how we found clients by working together instead of competing

I’ve been thinking about something that I haven’t seen discussed much in the hub, and I want to test the idea here.

For the last 2 years, I’ve been solo-ing most of my work—individual campaigns, individual pitches, individual client management. It was sustainable but not scalable, and honestly, it was lonely.

About 6 months ago, another agency head I met in the hub (Svetlana, shout out) suggested we try co-marketing a campaign. Not a one-off collaboration, but actually putting out a joint offer to clients.

Here’s the pitch we came up with: “Cross-Border Campaign Package.” We’d take on clients who needed both Russian-market expertise and US execution (or vice versa). She’d handle the Russia side, I’d handle the US side, and we’d co-deliver.

I was skeptical. What if the client prefers working with one of us directly? What if we disagree on strategy? What if the logistics are a nightmare?

Turns out, none of those things were the real problem. Here’s what actually happened:

First 3 months: We got about 8 inquiries through the hub and our combined networks. Closer rate was maybe 50%—4 clients took us on. Three turned into solid 3-month engagements. One kinda fizzled because the budget dried up.

Next 3 months: With 3 case studies in our back pocket of actual cross-border work, our pitch got way cleaner. We updated our positioning, posted about the wins in the hub, and suddenly we were getting inbound. Ended up with 6 more clients.

What I didn’t expect: the partnership made us both more credible individually. Like, clients would sometimes contact me directly later for Russia-only work, or contact Svetlana for US-specific campaigns. The co-marketing package was the door opener, but it also built individual reputation.

Here’s the harder part: how do you structure the economics? We went 60/40 on profit based on who’s doing more work per project. But it’s been surprisingly easy because we trust each other and we’re transparent about effort upfront.

Also: how do you avoid scope creep when you’re co-delivering? We built a lightweight SOW that basically says: “Here’s what we own individually, here’s the integration point, here’s who’s the client’s primary contact.” Took us a few projects to iron it out, but once we did, it was smooth.

The other thing I realized: this basically turned into a steady stream of leads. Instead of me hunting for clients monthly, we’re hunting together, which is way more effective. We feedback leads to each other, we pitch together, we close together.

I’m wondering if this is replicable with other people. Like, could we add a third agency to the package and scale further? Or does it break at some point?

Also, has anyone else tried actual co-marketing with partner agencies? What worked and what didn’t?

This is the next evolution of what we’ve been talking about in the hub. Co-marketing is way more powerful than referrals because you’re not just sending a lead—you’re delivering together, which means the client can’t pit you against each other and you have tighter margins on delivery.

Your 50% close rate and then growing inbound through case studies is the playbook. You proved it works, and now you’re getting signal.

On scaling with a third partner: I’d be careful. Two agencies have a clear division of labor (you handle X, I handle Y). Three gets messy unless you have totally distinct specialties. Like, if Partner C handles a third market or a totally different service line, it works. But if you’re three agencies doing similar things, you’re just adding coordination overhead.

I’ve seen two-person co-marketing work for 2-3 years really well, then hit a ceiling. Then you either split (and they become colleagues again) or you actually merge. The in-between is friction.

That said, what if you kept the two-person package tight, and then brought in specialists from the hub as project partners rather than permanent partners? Like, for specific projects, you’d bring in a UGC expert or a media buyer. That scales without organizational overhead.

Oh! Hi! I’m honored that you mentioned me. This partnership has honestly been some of the most fun work I’ve done in 5 years. And you’re right—it opened doors we didn’t expect.

One thing I want to add for others reading this: the reason it worked was because we genuinely liked each other and we had complementary skills, but we also invested time upfront getting aligned on values, decision-making, and communication.

We spent like 3 hours on a call just talking through ‘What bothers us about typical agency partnerships?’ and ‘How do we want to treat clients differently?’ That alignment was worth its weight in gold.

I’d also say: if you find someone for a co-marketing partnership, do a small test project first. Don’t jump straight to “let’s launch this together globally.” Do one campaign, see how you work together, then scale.

To your question on adding a third partner: I think it depends on the person and the structure. If they’re genuinely specialized in something we’re not, I’d be open. But if they’re mostly just distributing clients and also doing the work we already do, it dilutes what makes our offer special.

Love this collaboration and can’t wait to see where it goes.

I’ve been edges of trying this. Got a partner in the US who I’m testing something similar with—mostly collaboration on specific clients rather than a full package yet.

What I’m learning: the economics get complicated fast if you’re not super clear. Like, if a project is 50/50 effort, great—60/40 split makes sense. But if one of you is doing 80% of the work but the other brought in the client, how do you split?

We solved it by saying: “Whoever brings in the client gets a 10% finder’s fee off the top. Remaining profit splits based on hours worked.” It’s more admin, but it removes ambiguity.

Also: you need an actual contract. I thought we could handshake agreement with my partner. We couldn’t. There were three things that came up in month two that would’ve exploded without contractual clarity. Not huge things, but enough that I got a lawyer involved and drafted a 2-pager on how we handle disputes, IP ownership, and exclusivity.

Do that before you’re at conflict stage.

From a creator perspective, I notice the difference immediately when an agency is co-marketing versus flying solo. When you’re partnered, the whole pitch feels more… solid? Like, there’s redundancy built in, and that actually makes me more comfortable committing.

I’ve done collabs where it was just one person managing both sides of a campaign, and there were always these weird handoff moments or gaps. When it’s two people actively co-managing, the client experience is cleaner.

I’d imagine for brands buying your services, it’s the same thing. The co-marketing angle isn’t just about market coverage—it’s about having built-in quality control.

Strong operational move. A few things to track to make sure this actually scales:

  1. Unit economics: Track profit per project across all your co-marketing clients. Are you making more or less per client than you would solo?

  2. Client retention: Co-marketed clients—are they stickier than solo projects? (Hypothesis: yes, because switching costs are higher if two agencies are integrated)

  3. Project delivery time: Did co-marketing increase or decrease your time to execution? (Hypothesis: small increase due to coordination, but offset by higher quality)

  4. Sales cycle: How long from inquiry to close on co-marketed package vs. your typical solo sales process?

If co-marketing wins on all four, you’ve got a moat. If it wins on some but loses on others, you need to know which ones matter most.

Also: have you thought about what happens if one of you wants to exit the partnership? Or if someone gets acquired? Those scenarios seem distant now, but putting them in writing saves heartache later.

Let me put some hypothesis on this:

Your 50% close rate on co-marketed services vs. what you were closing solo (which was presumably lower?) is a data point, but we need baseline. Like, were you closing at 30% solo? 10%? If the gap isn’t huge, the co-marketing might just be adding legitimacy, not changing fundamentals.

Also: your inbound climb in months 4-6. Is that from the co-marketing package specifically, or is it compound effect of having more case studies + being more visible in the hub + just time passing?

To actually know if co-marketing is driving new logo acquisition, I’d suggest:

  • Track where each lead comes from (warm intro, hub visibility, referral, etc.)
  • For co-marketing package leads, what % of budget are coming from the package vs. adjacent services?
  • Are co-marketing clients actually 3-month engagements, or are some of them short-term, low-value projects where the package just made it easier to commit?

I’m not being skeptical to be harsh—I’m asking because if this is actually working at the margins, you probably want to invest more. But if it’s just a better sales story wrapped around the same economics, you should know that too.

This is exactly the kind of partnership model I’ve been thinking about for my US expansion. Instead of hiring a US operations person (which seems expensive), what if I just partner with someone who’s already operating here?

Question: how did you vet Svetlana as a partner before committing to co-marketing? Like, what made you trust her enough to put your reputation on the line?

Also—did you do any contracts upfront, or did you just start and figure it out?

I’m asking because I’m trying to find partners in the US market, but I don’t know how to evaluate if someone’s trustworthy before we’ve actually done significant work together.
