Write the breakup clause before you write the logo

Before you register anything, sit down with your friend and answer one question in writing: how does one of us get out?

Not if. How. What triggers a buyout, who values the business, on what formula, over how long, and what the person leaving can and can't do afterward. If you can have that conversation calmly on a Tuesday in month zero, you can probably survive the rest. If it feels too awkward to raise, you've already learned something important, and it cost you nothing.

Most people do it backward. They buy the domain, design the logo, split it down the middle because that feels fair and friendly, and start taking work. Two years later one of them is doing most of the selling, the other is doing most of the delivery, neither thinks the split is fair anymore, and nobody knows how to say so. The business limps. The friendship goes first.

The failure math nobody wants to hear

A lot of small businesses close in the first few years. That's true of solo operations too, and it isn't a reason to avoid starting one. But a partnership adds a failure mode a sole proprietorship doesn't have: the business can be working fine and still come apart because two people stopped being able to talk to each other.

Go in expecting a meaningful chance this ends. Not because you're pessimistic, but because the version of you who plans for the ending writes better documents than the version who assumes you'll always get along. You already do this with other things you love. You get a will. You wear a seatbelt on the drive to church.

Fifty-fifty is the most dangerous number

An equal split feels like friendship. Structurally, it's a machine for producing deadlock. Two owners, equal votes, no tiebreaker. The first genuinely hard disagreement — a hire, a client you should fire, whether to take on debt — has no mechanism for resolution except one person caving or both people stewing.

Fix it one of three ways.

• Split by decision domain. One of you owns sales, pricing and client relationships. The other owns delivery, hiring and operations. Inside your domain, you decide, and the other person's job is to disagree once and then support it. Write the list down. Every recurring decision in the business should have exactly one name next to it.
• Make it 51/49 and be honest about why. Usually one person brought the book of business, the capital, or the idea. Uneven equity with an honest reason beats even equity with a quiet resentment.
• Name a tiebreaker in advance. An outside advisor with a small stake, or a named person you both trust who gets called in when you're stuck. This works less well than it sounds, but it's better than nothing.

Whatever you choose, the conversation matters more than the mechanism. The point is to prove you can talk about power without either of you flinching.

Vest the equity, including yours

Founder equity should vest over time. Four years is common, with a one-year cliff, meaning nobody owns anything outright until they've been in it a year.

Do it even though you trust him. Especially because you trust him.

The scenario you're protecting against isn't betrayal. It's life. Eight months in, his wife gets a job offer in another state, or his father gets sick, or he realizes he hates this and wants his old salary back. Without vesting, he walks away owning half a business he no longer works in, and you spend the next decade building value for someone who isn't there. With vesting, he leaves with what he earned, you both feel fine about it, and you still go to each other's kids' baptisms.

Money in, money out, and the effort gap

Write down three separate things, because people conflate them and then argue.

Capital. If one of you puts in cash and the other doesn't, treat the cash as a documented loan to the business with a repayment schedule and a rate, not as extra equity. Loans get repaid and then it's over. Extra equity is forever, and it distorts everything after.

Pay. Decide what each of you draws every month, and revisit it on a set date, not in the middle of an argument. In a service business the cash is lumpy. Agree now what happens in a bad quarter: do you both cut to the same number, or does the person with more savings absorb more? Say it out loud while you're friends.

Profit. Distributions follow ownership. Pay follows work. Keeping those separate prevents the most common blowup, which is one partner working sixty hours and the other working twenty while both take home the same amount.

Define "full time" in actual terms. Is it a day count? A response-time expectation? Can either of you take outside consulting work? What happens if one of you takes a job? These aren't insulting questions. They're the questions you'll wish you'd asked.

The exit document

Get a business attorney to draft a buy-sell agreement. This isn't a place for a template you found online, and it isn't expensive relative to what it prevents. Ask a CPA about the tax treatment of whatever structure you pick, and ask an insurance professional about funding a buyout if one of you dies or is disabled.

What it needs to cover:

• Triggers. Death, disability, voluntary exit, a partner wanting to sell to an outsider, a partner failing to perform.
• Valuation. Agree the formula now. A multiple of trailing profit, an independent appraisal, or a number you both revisit and initial every January. Any of those beats arguing about it later when one of you has a lawyer and a grievance.
• Terms. A buyout paid over years is survivable. A buyout due in thirty days kills the company and the person still running it.
• Non-solicitation. In a service business, the clients are the business. Say clearly what a departing partner can and can't take.
• Right of first refusal, so neither of you ends up in business with a stranger.

Some people include a shotgun clause: either partner can name a price, and the other must buy or sell at that price. It resolves deadlock fast. It also favors whoever has more cash and more stomach. Know the trade-off before you sign it.

Protect the friendship as its own thing

Put a standing weekly meeting on the calendar with a written agenda. Look at the numbers together monthly, both of you, in the same room, so neither becomes the person who "handles the money." Once a quarter, ask each other plainly: is this still working for you, and what's the thing you've been avoiding saying?

Then build a fence. Dinner with your wives isn't a business meeting. Sunday isn't. If one of you starts a sentence about receivables at a kid's birthday party, the other gets to say "Monday," and nobody takes offense.

The businesses that hold up are the ones where the friendship gets scheduled maintenance too, not just the P&L.

You'll know it worked when the company is long sold or long closed, and he's still the guy you call first.
