What are mergers and acquisitions? Lessons from my first exit

The exact percentage shifts with the study, the sector, and the rather slippery question of what counts as “value,” but the warning is sound enough to haunt every founder who hears a banker whisper “strategic fit” over cocktails.

It is also why the modest $598,000 sale of a small hardware startup called TinyPilot in April 2024 is worth dissecting. The textbook answer to what are mergers and acquisitions conveniently skips the part where the deal room is where optimism gets priced, negotiated, escrowed, and occasionally beaten to death by a twelve-page indemnity schedule.

I have sat in enough of those rooms to recognize the choreography. The buyer’s slide deck, polished and patient. The seller’s nerves, polished less. The lockup. The reps and warranties nobody reads with enough dread at signing and everybody rereads with great intensity a year later.

Most founders will not negotiate a marquee tech acquisition with a fleet of investment bankers circling the table. They will, however, write smaller cheques, sign smaller purchase agreements, and encounter exactly the same structural problems. What changes is the lawyer’s hourly rate and the size of the wire. Everything else is plumbing.

The mechanics of consolidation: stock purchases vs. asset purchases

When somebody asks what are mergers and acquisitions — or, as bank decks sometimes phrase it, what is M&A in business terms — the honest answer is that the acronym covers related but different transactions.

A merger combines companies into one corporate structure. An acquisition transfers ownership or control of a business from one party to another. In practice, particularly for founders selling a closely held company, the conversation usually lands on one of two structures: a stock purchase or an asset purchase.

That choice is not a technicality to leave entirely to the lawyers. It decides what the buyer receives, what the seller remains responsible for, how contracts move, and where unpleasant surprises have somewhere to hide.

A stock purchase buys the corporate entity itself: its assets, contracts, debts, tax history, dormant disputes, and whatever else has accumulated inside the shell. The buyer obtains the shares, and the business continues as the same legal organism under new ownership.

That can make a stock deal operationally cleaner. Customer contracts may remain in place. Employees remain employed by the same entity. Licenses and accounts may not need to be rebuilt from scratch. But the cleanliness is deceptive. A buyer is taking on the company’s past, including risks that may not become visible until long after the champagne has gone flat.

An asset purchase lets the buyer choose what comes over. Inventory, intellectual property, customer relationships, equipment, a domain name, specific contracts: these can be acquired without necessarily taking every legacy liability with them. The seller retains the entity, residual obligations, and the work of winding down whatever remains.

Buyers like asset deals because they provide optionality. Sellers often find them exhausting because businesses are rarely built as neat piles of transferable components. A customer agreement may require consent. A software license may be non-transferable. A key employee may need a new contract. A vendor relationship that existed mostly through habit and goodwill suddenly requires documentation.

The legal distinction matters, but it is also a preview of the post-close relationship. A stock purchase says, broadly, “I am taking over your machine.” An asset purchase says, “I am taking the parts I like, and we need to agree about every bolt.”

The strategic categories get talked about as if they were distinct species. They are not. A horizontal deal can be a sensible move toward scale or a panic purchase disguised as strategy. A vertical deal can solve a real supply problem or trap a company inside a business it does not know how to run. Conglomerates, meanwhile, have a special talent for making a presentation deck look more coherent than the operating reality.

That is the first M&A basic for founders: the deal structure is not paperwork after the “real” negotiation. It is the negotiation, translated into consequences.

The reality of the exit market: why so many deals fail to create value

The grim statistic gets repeated because it contains a truth, even when its precise number is debated: many mergers and acquisitions fail to produce the value their advocates promised. Depending on the methodology, research and post-mortems have placed the failure rate across a wide range, often somewhere between 70% and 90%.

That does not mean every deal is a disaster. It means the announcement is usually the easiest part.

A deal can be financially rational at signing and operationally disastrous six months later.

The usual post-mortems are depressingly familiar. Cultural integration collapses. Key people leave before their institutional knowledge has been transferred. The combined engineering roadmap becomes two tribes with competing priorities and incompatible habits. Finance argues over which purchase-order system survives. The integration budget that appeared “manageable” during diligence swells into something nobody wants to defend at the next board meeting.

The mechanism is human before it is financial. People do not surrender their judgment, their process, or their calendar because a logo changed on the building. The deal closes; the personalities do not.

This is why understanding mergers and acquisitions requires more than knowing who bought whom and for how much. The price is a hypothesis. The integration is the experiment.

For a founder selling a small company, this point becomes personal very quickly. The buyer may be acquiring the product, the customers, the cash flow, or the distribution channel. But they are also acquiring the undocumented way you make decisions: which supplier actually responds, which customer needs a phone call rather than a ticket, which part of the codebase breaks when someone “cleans it up,” and which employee keeps a critical process alive through memory alone.

Those things are not usually in the headline valuation. They are, however, where the value leaks out.

A smart seller should ask questions that sound less glamorous than “What multiple are you offering?”

1. Who will own integration after closing? If the answer is vague, the work will drift back to the founder by default.

2. What changes on day one, and what is deliberately left alone? Buyers who want to change everything immediately are often buying a business they have not yet understood.

3. Which people, contracts, and systems are indispensable? “Indispensable” should mean named and documented, not merely mentioned in a diligence call.

4. What does success look like after the handover? Revenue retention, product continuity, customer migration, and team stability are different objectives. A buyer that cannot prioritize them is not ready to manage the transition.

5. What happens when the original plan fails? It will fail somewhere. The useful question is whether the parties have already agreed on who absorbs the pain.

The founders who survive an exit intact are not always the ones who negotiated the highest multiple. They are often the ones who decided, before signing, which battles would still exist after the wire cleared.

The cost of selling: broker fees and the closing accounting nobody shows you

The number that scares first-time sellers is not the headline price. It is the number that arrives after the wire transfer, minus the three other numbers they forgot to model.

A small-business exit can consume a meaningful share of total transaction value once legal fees, broker commissions, escrow reserves, indemnity holdbacks, tax work, and the small army of advisors have taken their seats at the table. TinyPilot’s founder paid a 15% broker fee for a buyer the broker sourced, structured, and helped bring to closing.

That fee looks brutal when isolated from the transaction. It looks less absurd if the broker created a competitive process, found the buyer, managed the back-and-forth, and got a deal completed that the seller could not have replicated alone. The relevant question is not whether a broker fee hurts. It does. The question is whether the broker’s work produced more value than it extracted.

These ranges are not promises. They are reminders that gross proceeds are a press-release number, while net proceeds are the number that changes your life.

There are also costs that do not fit neatly into a table. Time spent answering diligence questions is time not spent running the company. A distracted founder can let revenue soften during the sale process, which gives the buyer leverage precisely when the seller needs confidence. A poorly organized data room can turn a manageable diligence request into a month of forensic archaeology. An aggressive holdback can leave a seller technically wealthy and practically unable to use a portion of the money for a long time.

The cleanest way to think about an exit is not “What did I sell for?” It is “What did I receive at close, what remains at risk, and what obligations did I sell along with the company?”

Plan around the net number. Plan around the delayed number. Plan around the number that may be disputed if a buyer decides a warranty was breached. The headline valuation is not fake; it is simply incomplete.

The documentation playbook: how a Notion folder shaved 55 hours of post-sale work

This is the part I want tattooed on the forearms of every founder I advise.

When Michael Lynch sold TinyPilot in April 2024 for $598,000, he had spent the preceding months building a detailed operations playbook in Notion. Recurring tasks, vendor relationships, support runbooks, and the ordinary machinery of the business were explained in language a stranger could follow.

The result was a quiet but devastating advantage at closing: his estimated post-sale consulting burden dropped from 80 hours to 25.

The deal does not end at the wire transfer. It ends when the buyer stops calling.

Most founders treat documentation as a virtuous chore they will get to later. Later is usually when the buyer has churned through a few confused employees and has begun to wonder, privately and correctly, whether the acquisition was a mistake.

Documentation is not a moral exercise. It is leverage.

Every page written before a sale is a transition call you may not have to take afterward. Every workflow captured is less room for a buyer to claim they were misled by an undocumented dependency. Every vendor relationship mapped out is one less frantic search through old inboxes after the person who knew the password has left.

A usable operating playbook does not need to become a corporate museum. It needs to answer the questions a competent new owner will ask in the first weeks:

• What happens every day, every week, and every month?
• Which systems actually run the business, and who has access to them?
• Which customers or vendors require personal handling?
• Where are the recurring failure points?
• What does a normal support escalation look like?
• Which decisions are policy, and which are founder instinct?
• What has been tried before and quietly failed?

The last question is the one founders routinely omit. Buyers do not merely need a map of what works. They need a record of the expensive dead ends that nobody should repeat.

Fifty-five hours may not sound like much in the abstract. In a transition, it is the difference between a clean handoff and a slow bleed of calls, messages, emergency requests, and emotional obligation. It is also the difference between being able to begin your next chapter and discovering that you sold the company but retained the job.

Build the playbook before you shop the company, not after the buyer asks for it. By then, the missing documentation has become a negotiating weakness.

The trap of seller financing: why installment payouts can keep founders tied to a deal

Seller financing deserves suspicion, not superstition.

It is not automatically a bad structure. In some deals, it can bridge a genuine financing gap, widen the buyer pool, or produce a higher nominal price. A buyer may pay part of the consideration at closing and issue a note for the rest, to be paid over time. For the seller, that can look attractive: more total consideration, interest income, or a path to completing a transaction that otherwise would not happen.

It can also turn the seller into an unwilling lender to a buyer whose operating judgment they no longer control.

The danger is straightforward. Once the business changes hands, the buyer decides how it is run. They may cut staff, mishandle customers, overextend on expenses, or discover that the business was harder to operate than the spreadsheet implied. If their cash flow weakens, the installment payment becomes negotiable in the worst possible sense. The seller’s remedy may be a dispute with an owner whose balance sheet has already been drained by the very business they bought.

Lynch’s warning from his own exit lands because it is practical rather than ideological: when money is paid over time, the seller can end up continuing to work for the buyer without a real employment agreement, benefits, or a severance clause. The buyer calls because they need help protecting the asset that is supposed to fund the remaining payments. The seller answers because they need the remaining payments.

That is not a clean exit. It is a relationship with different stationery.

Seller financing may be unsuitable in many founder-led deals, especially where the buyer is thinly capitalized, the business depends heavily on the founder, or there is no credible collateral behind the note. But if a seller considers it, the risk should be treated as credit risk, not as a friendly accommodation.

That means asking harder questions:

• How much cash is actually paid at closing?
• What security supports the deferred amount?
• What happens if the buyer misses a payment?
• Can the seller reclaim assets or enforce a personal guarantee?
• Is the seller expected to provide ongoing support, and is that support separately compensated?
• Does the buyer have sufficient working capital after the transaction, or are they buying the business and immediately starving it?

If the buyer cannot pay the full price in cash, that is information. It is not necessarily a reason to walk away. But it is a reason to stop treating the stated purchase price as cash equivalent.

You can renegotiate the price to match actual liquidity. You can reduce the deferred portion. You can insist on stronger protections. You can decide the risk is worth taking because the buyer is credible and the structure is secure. Or you can walk.

What you should not do is confuse an IOU with a completed exit.

What I take away from the TinyPilot tape

Here is the lesson I keep returning to.

Understanding what are mergers and acquisitions at the deal-table level means accepting that signing is not the finish line. It is the opening bell for a transition period in which every undocumented vendor relationship, every fuzzy representation, every vague consulting obligation, and every deferred payment can come back to bill you.

The best exit is not always the highest headline number. It is the deal that leaves the buyer able to operate, the seller able to leave, and both sides clear about what remains unresolved.

Know whether you are selling stock or assets. Model the net proceeds rather than admiring the gross figure. Document the business until a competent stranger can run it. And if part of the price arrives later, evaluate it with the caution you would bring to any loan.

That is what M&A basics for founders really amount to: not a vocabulary lesson, but a refusal to let a flattering offer make you careless.

Now go document your playbook. Before somebody writes the cheque.
