I ran a brand for ten years before I started Bylders.
And I'll tell you the single most exhausting thing about that decade:
it wasn't tariffs.
It wasn't iOS 14.
It wasn't even the supply chain meltdown of 2021.
It was the agency call.
You know the one. Paid is on the call. Email is on the call. Maybe Amazon is on the call too. Numbers are down. Everyone has a deck. Everyone has a story. And by minute 47, you realize what's actually happening:
Three agencies are on a Zoom together, all charging you retainers, all pointing at each other.
Nobody's wrong, exactly. Paid is right that email isn't capturing the traffic. Email is right that paid is sending unqualified clicks. Amazon is right that the DTC store is cannibalizing their listings. Everyone has a defensible position. Nobody is moving the number.
This is the silent tax most 7- and 8-figure brands pay every single month. And it's not because the agencies are bad. It's because the model is bad.
The "best of breed" trap
Somewhere along the way, the industry decided that the smartest brands hire specialists. One agency for paid. One for email. One for SMS. One for Amazon. One for creative. One for CRO. The logic sounds good — depth beats breadth, you get A-team talent in every channel.
What actually happens is this: each agency optimizes the slice of the funnel they get paid on. Paid optimizes for ROAS. Email optimizes for click rate. Amazon optimizes for BSR. None of them optimize for the only number that actually pays your bills, which is contribution margin per customer over 12 months.
And when results dip, every agency has an incentive to make sure the dip looks like someone else's fault. Not because they're bad people. Because their renewal depends on it.
How Graham and I started doing it differently
My partner Graham runs Pixel Theory. They're a growth partner — paid social, paid search, performance creative, and the strategic layer that ties it all together. I run Bylders, where we live and breathe retention: email, SMS, lifecycle, and the 60% of revenue that comes after the first click.
Naturally, our ideal customers are the same brand. A founder doing $5M to $50M who needs both top-of-funnel that actually converts and a back end that actually retains. So a few years ago we started showing up on each other's pitches. Then on each other's accounts. Then on each other's Slack channels.
Brands where our teams currently work side by side: Heirloom Coffee Roasters, Kēpos, Fazit Beauty, Optimize Minerals, and a growing list of others.
What we discovered is something we should have seen coming, but didn't fully appreciate until we lived it: when the retention agency and the growth agency are already on the same Slack, already share a roadmap, and already get on a Tuesday call before the client call — the math changes.
What actually changes when your agencies are partnered
1. The handoff stops being a black box
When Pixel Theory pushes a new audience into a paid test, our team at Bylders knows about it before the spend kicks in. Which means by the time those new customers hit the welcome flow, the welcome flow already knows what creative they saw, what offer they clicked, and what to say next. No more "wait, who are these people and why is the open rate so weird this week."
2. Creative stops being three different campaigns
Most brands are running three brands at once and don't realize it. The paid agency built one. The email agency built another. The Amazon team built a third. Our teams share the creative brief. The hook that's working in a Meta ad becomes the subject line in the post-purchase flow on Wednesday. The repetition isn't accidental — it's the strategy.
3. Bad weeks get diagnosed in 24 hours, not 24 days
When revenue dips, our two teams are already in a shared channel pulling the data together. We can usually tell you within a day whether it's a top-of-funnel problem, a list health problem, an offer problem, or a Klaviyo deliverability problem. No finger pointing. No "let me get back to you next week with my side of the data."
4. You stop paying for the same work twice
You'd be amazed how many brands have their email agency building the exact landing page the paid agency is sending traffic to — and how often those two pages don't match each other. When the agencies are partnered, that doesn't happen. One brief, one execution, one source of truth.
5. The compounding shows up in month four, not month one
This is the part that's hard to put in a deck. Two teams working together for the third time on the third client get sharper, faster, and more in sync than any single team can on its own. Our Bylders strategist already knows what Pixel Theory's media buyer is going to ask for. The channels are shorter. The decisions are faster. The results compound.
What to do tomorrow if your agencies aren't talking
Get them on a recurring 30-minute call without you. If they push back, that's the answer.
Share one north-star metric across both contracts. Not ROAS, not open rate. Contribution margin per new customer at day 90.
Ask each agency to name one thing the other agency does that helps them. If they can't, they aren't actually partnered — they're co-existing.
Build one creative brief, not three. The hook that works on Meta should be the same hook in your welcome series.
If your two main agencies don't already have a working relationship, consider hiring a pair that does.
The part where I tell you what we do
Look — the whole reason I'm writing this is that we've quietly built something we think is rare. A growth partner and a retention partner who actually want to be on the same call. Who share a Slack. Who don't bill you to argue with each other.
If you're running a 7- or 8-figure consumer brand and you're tired of refereeing your agencies, that might be the most valuable thing we can offer you — not the email flows, not the paid creative, but the fact that we already know how to work together.
