If you spend any time in business circles right now, you've heard about ETA, Entrepreneurship Through Acquisition. The idea is simple: instead of starting a company from scratch, you buy an existing one, usually a small or mid-sized business (SMB) with a retiring owner, and step in as the new owner-operator.
It got its start in academia. Harvard professors Rick Ruback and Royce Yudkoff built a now-famous ETA course at HBS and turned it into the canonical book, the HBR Guide to Buying a Small Business. Then Walker Deibel wrote a book called Buy Then Build, which pushed this concept further into the mainstream. Now there are podcasts, newsletters, conferences, search funds, and a whole cottage industry of advisors built around it. Business Insider literally called it the "hot new MBA hustle."
And on paper, the pitch is beautiful. There's a wave of baby boomers retiring with no succession plan. You can buy a profitable, boring business for a reasonable multiple, often with an SBA loan and very little of your own cash. You skip the brutal zero-to-one phase of a startup and walk into existing revenue, existing customers, and existing cash flow. What's not to love?
I get a lot of questions about ETA, and I want to issue a warning. Not to talk anyone out of it, but to make sure people walk in eyes wide open instead of eyes wide shut.
The biggest risk in ETA isn't the deal
Most of the conversation around ETA is about the front half: how to find a deal, how to raise capital, how to finance it with an SBA loan, how to negotiate with the seller. That's the part the courses and books cover well.
But here's the one major issue almost nobody talks about, and it lives entirely on the back half, after you own the thing:
Existing businesses are extremely reluctant to change.
Anyone who has spent real time inside a small or mid-sized business understands this in their bones. When a company has been around for 30 years, something as small as switching the brand of coffee in the break room can trigger a revolt. I'm not exaggerating. The team has a way of doing things, and that way is sacred, not because it's good, but because it's theirs.
Now look at what most ETA buyers tell me they plan to do the moment they take over. They're going to overhaul marketing. Rebuild the sales process. Redo compensation. Install a real CRM. Introduce AI and modern technology. Tighten up operations.
Every one of those moves makes total sense on paper. I'd probably recommend most of them myself. But there's a canyon between "makes sense on paper" and "actually gets implemented," and that canyon is where ETA dreams go to die, especially because the majority of ETA buyers have absolutely no experience managing a team, let alone getting a team to go along with big change.
Why ETA acquisitions actually fail: execution, not theory
I've tried to help more struggling businesses than I'd like to count. The pattern is almost always the same. The owner and I sit down, diagnose the problem, and design a fix. We run the numbers. It pencils out. Sometimes the solution would literally save the entire business.
And then... nothing happens.
Not because the idea was wrong. Because the existing team wouldn't, or couldn't, execute it. They nod in the meeting, then quietly drift back to the old way the second the door closes. I wrote about this in Small Tweaks Won't Save a Sinking Ship: in most small and mid-sized companies, the team isn't capable of, empowered to, or interested in making deep, risky changes. They default to minor tweaks, because tweaks feel safe.
That's the part ETA buyers underestimate, and I think I know why. They're working from theory. They've never lived the implementation.
You hear this everywhere if you listen for it. I'm a regular listener of Acquiring Minds, Will Smith's podcast that interviews people who've actually bought businesses through ETA. When these stories go sideways, it's rarely because the strategy was flawed. The math worked. The thesis worked. They just couldn't get the people inside the building to execute it.
The theory isn't the hard part. The execution is. And execution runs straight through human beings who were there long before you showed up with your spreadsheet and your big plans.
How to de-risk an ETA acquisition
Yes, there's a way through, but it requires being brutally honest with yourself before you buy. A few takeaways:
Buy a business that doesn't need to change to succeed. This is the big one. Look for companies whose current operations can healthily support the business as-is. If your acquisition thesis depends on you walking in and changing everything to make the numbers work, you're stacking enormous execution risk on top of an already hard situation. Buy a good business at a fair price, not a broken one you're betting you can fix. If change is required for survival, you may not get to make it in time.
Plan changes in quarters and years, not weeks and months. Whatever timeline you have in your head, multiply it. Real change in an established company is slow, painfully slow. The buyers who get frustrated and force it fast tend to blow up morale and lose their best people. Patience isn't a virtue here, it's a survival strategy.
Be ready to let a lot of people go. This is the uncomfortable truth I've watched play out again and again in the companies I've consulted for. For almost every meaningful change you want to make, you'll have to part ways with people who simply won't change with you. And it's not just about the individual, it's that one person's "this is how we've always done it" attitude is contagious. If you let it linger, that toxicity rubs off on the employees who were willing to adapt. Going in, assume that real change and real turnover go hand in hand. Barrett Ersek lived the extreme version of this: he came back to his existing team with a genuinely great idea, they shut it down, and he ended up selling the whole company and rebuilding from scratch with a new team that actually wanted to build it.
A thought for the AI era: buy, or rebuild?
There's a bigger question lurking underneath all of this, especially now with the rise of AI.
If the hardest part of ETA is dragging an unwilling team and legacy systems into the modern era, and AI is making it dramatically cheaper and faster to build from the ground up, then maybe, for some industries, the smarter play isn't buying the incumbent at all. Maybe it's replicating the business you'd want to buy and building it AI-first from day one: the right processes, the right systems, and a team that actually wants to adopt new technology, with none of the 30-year-old baggage.
I've made this case before. That most businesses won't survive the jump to AI-first. That there are four distinct stages of AI adoption most companies stall out in. And that disruption almost always comes from outside the incumbent, not within it. An ETA buyer inheriting a 30-year-old team is betting they can pull off the thing incumbents almost never manage.
Next steps
For now, if you're seriously considering entrepreneurship through acquisition: go in eyes wide open. The deal is the easy part. The people are the business, and the people are exactly what you can't change as fast as your spreadsheet says you can.
