Most people assume a successful investor’s job is finding great companies. Adrian Vanzyl would argue the bigger part of the job is saying no. He does this over and over, to companies that look perfectly reasonable on paper. The math of venture investing makes this unavoidable. However, the discipline of doing it well is rarer than it should be.
This isn’t about pessimism or excessive caution. Instead, it’s about understanding what the job actually requires, and building a process that reflects that reality honestly.
Why the Base Rate Forces Constant Rejection
Venture investing runs on a brutal numerical reality. Most individual investments will underperform or fail outright. A small number of outsized winners have to carry the entire portfolio’s return. Given that structure, saying yes too often isn’t generous. It’s actually a failure of discipline that dilutes the few bets that matter most.
Consequently, a healthy investing process involves rejecting the overwhelming majority of opportunities that come through the door. This isn’t a sign that the market lacks good founders. Rather, it reflects the sheer volume of opportunities relative to the narrow slice that will actually justify real conviction.
The Danger of Saying Yes to Avoid Discomfort
Saying no is socially uncomfortable in a way that saying yes rarely is. Declining a founder who’s poured years into their company feels harsh, even when it’s the right call. As a result, some investors drift toward saying yes more often than their own judgment actually supports. They do this simply to avoid the discomfort of delivering bad news.
This pattern is easy to justify in the moment and costly over time. A portfolio built partly on avoided discomfort, rather than genuine conviction, ends up diluted. It fills up with investments that never had a strong thesis behind them in the first place. Notably, the discomfort of a difficult no is temporary, while the cost of a weak yes compounds for years.
How Adrian Vanzyl Thinks About a Good No
A good no isn’t simply a rejection. Instead, it’s a clear, honest explanation of why the fit isn’t there, delivered in a way that respects the founder’s time and effort. Vague, hedged rejections waste everyone’s time. They often leave founders more confused than if no explanation had been given at all.
Specificity matters here. Consider a no that says the market feels too early right now. That gives a founder something they can actually act on. By contrast, a vague no that says it’s just not quite right gives them nothing to work with. It often signals the investor didn’t engage seriously with the pitch in the first place.
Why Speed Matters Almost as Much as Honesty
Founders operate on limited runway and can’t afford to wait indefinitely for a decision that was never going to be a yes. An investor who strings a founder along imposes a real cost on that founder’s fundraising timeline. This holds true whether the delay comes from genuine indecision or simple avoidance.
A fast no is almost always kinder than a slow one, even though it doesn’t always feel that way to deliver. Founders consistently report valuing investors who decide quickly and communicate clearly. This holds even when the answer disappoints them, over investors who take weeks to arrive at the same conclusion.
The Long-Term Value of Saying No Well
How an investor handles rejection shapes their reputation across an entire startup ecosystem. Often, this matters more than their occasional big wins do. Founders talk to each other constantly, and word about how an investor treats people during a pass travels just as fast as word about a great outcome.
An investor known for clear, respectful, timely rejections builds a reputation that pays off well beyond any single deal. Founders who were once told no, and treated well in the process, often come back with the next company they build. They also refer other founders into that investor’s pipeline. A careless or dismissive no does the opposite, quietly, over years.
What This Means for Investors Evaluating Deals
For any investor building a real process, the practical discipline is straightforward, even if it’s uncomfortable to practice consistently. Expect to say no far more often than yes, and treat that as healthy rather than as a failure. Make the no specific enough that it’s actually useful. And deliver it quickly, since a fast, honest rejection respects a founder’s time in a way a slow, vague one never can.
That’s the standard Adrian Vanzyl applies to every pass. He understands that how he says no shapes his reputation just as much as any single yes ever could.
