Something odd is happening in marketing right now.

Output is way up. Results are down. Business owners tell me they’re publishing more content, sending more email, and running more outreach than ever, and the phone rings less than it did 2 years ago.

Here’s what I think is going on.

The great flattening

AI made competent marketing cheap. Any business can now produce a decent blog post, a polished cold email, and a professional-looking ad campaign in an afternoon.

So everyone did.

The result is a flood of marketing that all sounds the same. Buyers can’t tell who’s good anymore because everyone looks good on paper. And when everything looks professional, professional stops meaning much.

Two more shifts pile on. Ad costs keep climbing, and I don’t need to quote a stat you’ve already felt in your own budget. And buyers are doing more of their research inside AI assistants. They ask ChatGPT or Claude who to hire, get a summarized answer, and may never see your website at all.

Add it up and the channels most businesses depend on for new customers (content, ads, outbound) are getting louder, pricier, and less believable all at once.

The half of the journey nobody can automate

I’ve taught the Marketing Hourglass for 2 decades: Know, Like, Trust, Try, Buy, Repeat, Refer. Unlike a funnel, it widens back out after the sale, because the customers you keep and the fans you create are where the best growth comes from.

AI just made that second half a lot more valuable.

Anyone can generate Know, Like, and Trust content now. A delivered experience still has to be earned. So does a customer telling a friend, “hire these people, they took care of us.”

The bottom half of the Hourglass gets built one customer at a time, and that’s exactly why it’s about to become the highest-return part of your marketing.

I wrote this book 16 years ago

In 2010 I published The Referral Engine. The argument was simple: referrals are too important to leave to chance, so build a system that produces them.

Here’s a fact that surprises people. I’m known for Duct Tape Marketing, but The Referral Engine is my best-selling book. It still sells today, 16 years on. Owners have always understood at a gut level how much referrals matter, and the book keeps finding readers because the problem never went away.

What most readers didn’t have back then was urgency. Referrals stayed the nice-to-have channel, appreciated but never built for, because ads and SEO and email were working fine.

They’re working less fine now. And the ideas in that book turned out to be built for this exact moment. Here are the ones that matter most.

People are wired to refer

Making a good referral feels good. It’s social currency: introducing a friend to a great business makes you look smart and useful. That wiring didn’t change when the tools did.

Which means your customers want to refer you. Most just don’t, because nothing in your business makes it easy, obvious, or timely.

That’s a system problem. System problems have fixes.

A referral system beats a referral hope

Most owners treat referrals like weather. They happen or they don’t.

But a referral system has the same parts as any other marketing system: a clear picture of who you want referred, language your sources can borrow, an offer that makes the referrer look generous, a trigger for when to ask, and a way to track what came in.

Here’s the part that’s new. Follow-through used to kill referral programs. Somebody had to remember to ask, personalize the thank-you, keep partners warm. AI handles that kind of follow-through well now. The strategy still has to come first, but the old excuse about not having time is gone.

Referability comes before referrals

No tactic fixes an unremarkable business. Before any referral campaign, answer one question: what happens in your business that’s worth talking about?

Close the gap between what you promise and what customers experience. Then engineer one moment worth retelling. The surprise check-in. The problem you fixed before the client noticed it. The onboarding that felt like a welcome instead of paperwork.

Referrals are the byproduct of experience design.

Your best referral source may be another business

Direct referrals come from customers. Indirect referrals come from strategic partners: businesses that serve your exact customer right before or right after you do.

For most B2B companies, the partner engine is the bigger one, and the less built one.

Try this. List the 5 businesses your best customer hired in the 12 months before they hired you. That’s your partner shortlist. Teach those firms exactly who to send you, give them something worth giving away, and send business back on purpose.

I’ll give you a live example from our own shop.

My friend Mike Michalowicz runs a group of business advisors called Prosper. These are the people founders already trust with profit, operations, and the big picture. When one of their clients needs marketing leadership to hit a growth target, guess who gets asked for a name.

We’re working with 3 clients right now who came to us through that group. The engagements are going well, and going well is the whole engine: results for a referred client are what produce the next referral. Just recently, another advisor sent us a new client the same way.

The part worth studying is the order of events. Those first referrals showed up on their own. The system came second. Now we’re debriefing the advisors who send us business to learn what prompted each referral, defining exactly which founders we want sent our way, and building tools an advisor can hand a client the moment marketing comes up in a planning session.

Your business almost certainly has a pattern like this running right now. The work is spotting it, then formalizing it.

And a quick word if you’re a business advisor yourself. When a client needs marketing leadership and you want to hand them a name you can vouch for, that’s the exact gap our advisor partnership fills. See how the advisor partnership works.

The new part: AI is listening to your customers

Here’s what makes a 2010 book feel current in 2026.

When someone asks an AI assistant who to hire, the answer gets assembled from reviews, testimonials, case stories, and mentions scattered across the web. Your customers’ words are the raw material AI uses to describe and recommend you.

Word of mouth now travels machine to machine.

That turns review generation and testimonial capture into discovery infrastructure. Every satisfied customer is writing part of your AI sales pitch.

Try it yourself. Ask 3 different AI assistants who they’d recommend in your category and your market. Compare what they say to what your best customers say about you. The gap between those two answers is your work.

Where to start

Four moves for this quarter:

1. Track where your last 10 customers actually came from. Most owners are surprised by how much of their growth is already referral-driven.
2. Pick one moment in your customer experience and make it worth talking about.
3. Build your partner shortlist using the exercise above and set up 2 conversations.
4. Ask for reviews at high points (right after a win, a renewal, a thank-you email) and make it a 30-second task for the customer.

Do it in that order. A referral push with no strategy underneath it is just another random act of marketing.

The businesses that win the next few years will treat the second half of the Hourglass as their primary growth channel and build a system to run it. The good news is that your competitors are all busy generating more content.
