Picture a kitchen where the cooking has suddenly become instant. Any dish, ready in seconds.
You'd think the restaurant would fly. It doesn't. Because now the queue is at the person writing the menu. The chef is waiting, ready to go, with nothing new to cook.
That's roughly what happened at Mother Root, a fast-growing UK brand. It was the story Zaeem Bhanji, CEO of Yolodex, told at aiblLIVE in London on 20 October, with Tom, Mother Root's growth lead, alongside him.
Mother Root is no small side project. It came eighth in the Financial Times' first list of the UK's fastest-growing companies, published on 1 October 2026. Its revenue grew around 29 times between 2022 and 2025. Its growth runs on paid social ads on Meta.
Where the queue moved to
Zaeem opened with the line that framed the whole session. "AI has made producing ads easier and faster than ever, and this creates a new bottleneck."
The bottleneck was the brief. Making an ad had become fast and cheap. Coming up with a fresh, specific idea for each ad had not. Mother Root's strategist could write roughly one good brief a week. Everything else waited behind it.
So they put AI to work on the thinking. Yolodex reads the brand's ad account, its own and its competitors' reviews and competitors' ads, then groups customers into personas and drafts briefs from them. Customer interviews feed in every month. A human, the creative lead, approves every brief before anything gets made.
Yolodex's own figures from the project are strong: briefs live within two weeks, most of them ready for production, and twice as many ads a month. Those are the vendor's numbers from one client, and Tom was honest that it's "still early days, maybe a month in." So treat them as an early result.
What I found more useful was where they ended up. The bottleneck didn't disappear. It moved again, this time to production. That's how bottlenecks work.
The lessons slide
The last slide in this session is the one worth pinning up. Its advice was to find your real bottleneck, and for Mother Root that was the brief. "Production is becoming a commodity," it said. And: "Keep a human gate: the creative lead approves every brief."
And Tom's advice to the room was refreshingly old-fashioned. You should be doing customer interviews, he said, about 20 a month.
Production is the easy bit
Almost everyone adding AI to their marketing starts with production. Faster posts, quicker emails, more images. It's the easy bit to see.
But maybe your real problem is that you don't know what to say, or who you're saying it to. Then producing more of it faster just gets you more of the wrong thing. A small business can make a hundred posts in a week with AI. Very few can tell you what their customers were worrying about last Tuesday.
That's what Mother Root went looking for. It came from data, reviews and real conversations, and then AI helped turn it into briefs.
Think about every piece of content you'll put out this quarter. Now picture each one starting from something a real customer actually said. Their words, their worries, their reasons for buying. The content gets easier to write and better at its job, because you're no longer guessing.
You don't need Yolodex for that. You need a few conversations and somewhere to keep what you hear.
Maybe it's time you booked a few customer calls. Twenty minutes each, asking what nearly stopped them buying and what they'd tell a friend. Record them, with permission, and I think you'll find your next few briefs are already in there.
