The Decisions You Can’t Undo
In a startup, the hardest decisions to reverse all involve people.
The Three Most Irreversible Decisions in a Startup
TLDR: Most startup decisions are reversible. The ones that aren’t almost always come down to people. Here are three that stand above the rest: your co-founders, your investors, and your early hires. Think about the worst case before making these calls. If you can accept the consequences, move forward with confidence. If you can’t, slow down. And for everything else, stop treating it like it’s permanent.
Most startup decisions are reversible. You can pivot the product, change your pricing, scrap a campaign, redo your deck. The cost is time, but you recover.
The decisions that actually shape a startup’s trajectory are different. They involve people. In our experience, three people decisions stand above everything else in terms of how difficult they are to undo: the co-founders you choose to build with, the investors you bring on, and the early hires you make.
Hire slow, fire fast. It is a cliché because it is true. That does not mean you should be paralyzed. But I have always liked to think about worst-case scenarios before making these calls. Not to be pessimistic, but because if I can accept the consequences of the worst outcome, I can move forward with confidence. If I cannot accept them, that tells me I should not move forward yet.
The Co-Founders You Choose to Build With
The decision of who to build with is the single most irreversible choice in a startup. You can fire an employee. You can replace a vendor. But separating from a co-founder is surgery. It touches equity, IP, institutional knowledge, team morale, and investor confidence. Even when it goes well, it never goes cleanly.
Pick people you truly enjoy building with. At Moichor, Matt, Thanh, and I spent literally twenty-four seven with each other for over three years. We worked out of our Oakland apartment, played Overwatch at night, woke up, and did the same thing again the next day. That was our life. If we did not genuinely enjoy being around each other, it would have been unbearable.
Our relationship only strengthened with time. At first we were shy about talking about the hard stuff. Eventually we stopped holding back. We argued, got loud, patched things up, and moved on. That cycle became how we operated. Over time we became a package, and in the beginning that was viewed as a strength. Three founders who were completely aligned, inseparable, and deeply trusted each other. Later, as the company grew and more experienced leadership was wanted at Moichor, being a package was sometimes seen as a weakness. But looking back, that bond is what carried us through the hardest years of the company. It outlasted every other advantage we had.
If you are starting a company with someone you met recently, be honest about what you do not know about them yet. How do they handle bad news? Do they avoid conflict or lean into it? When things go wrong, do they blame or take ownership? You learn these things through shared difficulty, not conversation. If you have not been through something hard together, stress-test the relationship before you sign papers.
The Investors You Bring On
Of the three, investors are the hardest to reverse. The moment someone writes a check, they get shares or some right to your company that is essentially impossible to erase. A co-founder can be bought out. An employee can be let go. But an investor is on your cap table for the life of the company.
Do not take easy money. The excitement of someone wanting to invest can cloud your judgment about whether they are the right partner for a decade-long relationship. Capital is replaceable. The wrong investor is not. One of the most revealing things you can do is talk to founders in their portfolio whose companies did not work out. That is where you see an investor’s true colors. Did they disappear when things got tough, or did they show up with real help?
Once you bring investors on, do not over-promise. This is one of the most common traps, and one we fell into ourselves. You want to impress them. So you set expectations high. But if you put expectations at the ceiling on day one and then under-deliver, you create a trust problem that is very hard to fix. Set expectations you can actually meet. If you beat them, wonderful. But do not put yourself in a position where you are constantly explaining why reality does not match what you told them.
Over-communicate during the rough times. When things are hard, the instinct is to go quiet and try to fix the problem before anyone notices. That is a mistake. Your investors are managing many companies at once. Whether for worse or better, they are not in the weeds with you. They miss key details. This happened to us multiple times, situations where our investors did not have the full picture because we had not shared it proactively. By the time we did communicate, the problem had compounded and the conversation was harder than it needed to be. Silence does not signal strength. It creates surprise, and surprise destroys trust faster than bad news ever does.
The Early Hires You Bring On
Your first few hires are not just filling roles. They are setting the culture, the pace, and the standard for everyone who comes after them. Every early hire carries disproportionate weight because they become the template. How they work becomes how the company works. What they tolerate becomes what the company tolerates.
This is why hire slow, fire fast matters so much at this stage. A bad early hire does not just underperform. They set the wrong precedent. They create dynamics that the next five hires inherit. Before you extend an offer, ask yourself: if this person does not work out, can I live with the consequences?
The best early hires at Moichor, and the ones who stuck with us the longest, did not come from recruiters. They came from our own networks, our own instincts, and our own judgment about who would thrive in the chaos of an early-stage company. VCs often feel comfortable recommending recruiters because they have established relationships with them. And recruiters can be valuable later. But at the earliest stage, trust yourself more than you trust VCs and recruiters when it comes to hiring. They are not the ones who have to live with the consequences every day. You are.
Do not rush to fill a seat just because it feels like you should be growing. Before hiring, ask yourself whether you are solving a real bottleneck or just trying to feel like you are making progress. Leverage beats headcount, especially early on.
The Common Thread
Co-founders, investors, and early hires. All three are people decisions. All three are hard to undo. And all three shape the company in ways that persist long after the original decision stops feeling like a decision at all.
Think about the worst case. If you can accept it, move forward with confidence. If you cannot, slow down and figure out why. The founders who last are not the ones who avoid mistakes. They are the ones who give the irreversible decisions the weight they deserve, and save their speed for everything else.
The Flip Side
Most of the things founders lose sleep over are not actually irreversible. Pricing can be changed. Products can be rebuilt. A missed deadline is not a death sentence. If your product does not look great today, you ship a better version tomorrow. Most doors can be walked back through and fixed.
Do not treat every decision like it is permanent. Save that weight for the ones that actually are.
And those, as we have learned, almost always come down to people.
