Making Decisions Without Certainty: What Scientists Need to Learn When Building a Startup

Imagine you could meet two versions of yourself. The first carefully analyzes every decision and waits until all the information is available. The second decides earlier, tests ideas, makes mistakes, and learns from them.
Which one would likely have built the more successful startup after two years?
Probably not the person who tried to prepare every decision perfectly—but the one who learned the most along the way.
This highlights one of the biggest differences between academia and entrepreneurship: startup success rarely depends on making perfect decisions. Instead, it depends on acting quickly, gaining real-world experience, and continuously adjusting your course as you learn.
For many scientists, this mindset feels unfamiliar at first. Research is built on carefully testing hypotheses, collecting data, and critically evaluating results until they are robust. That approach is essential in science. But startups operate by different rules. Even the deepest expertise creates little value unless it is translated into concrete decisions and measurable progress.
Entrepreneurial success is not driven by knowledge alone but by consistently turning knowledge into action.
Especially in the early stages of a startup, the priority is execution. Rather than trying to eliminate every uncertainty before making a decision, founders need to move pragmatically, learn quickly, and keep taking the next step. Time is one of a young company's most valuable resources. Spending it on activities that generate neither meaningful insights nor customer value can mean losing critical competitive advantages.
The Trap of Analysis Paralysis
For Josua V., founder of Exomatter, one of the biggest challenges for scientists entering entrepreneurship lies in the habits of mind they bring from academia:
"Many researchers who make the leap into entrepreneurship carry a deeply ingrained mindset: before taking action, you first need to understand every relationship. Before making a decision, you need sufficient data."
While this approach is entirely appropriate in research, it can quickly become a barrier in entrepreneurship. If you always feel the need to read one more paper, test one more variable, or wait for one more iteration before making a decision, it's easy to fall into analysis paralysis, a state where excessive analysis prevents action.
The key mindset shift is to stop treating knowledge as an end in itself and instead see it as a means to an end. The goal is not to maximize what you know, but to generate the insights that create real value for customers and strengthen your business.
As Josua puts it: "Scientists who become founders have to get comfortable making decisions without certainty."
Moving Fast Without Compromising Scientific Rigor
Making decisions more quickly does not mean abandoning scientific standards. Instead, it requires consciously challenging your own perfectionism. A result doesn't have to be perfect to provide the next important insight. In many cases, "good enough" is all you need to gather valuable feedback from the market.
Josua illustrated this with the early development of Exomatter. The first version of the product was still far from technically perfect. Nevertheless, the team decided to test it with potential users as early as possible. Their focus wasn't on whether the code was flawless—it was on whether the product solved a meaningful problem. The feedback they received proved far more valuable than several additional months of internal optimization.
Treat Decisions as Experiments
One helpful way to think about decision-making is to treat decisions not as permanent commitments, but as experiments.
Very few entrepreneurial decisions are truly irreversible. More often, it makes sense to take the first step while defining in advance when—and by which criteria—you will evaluate whether your approach is working. This reduces the pressure of making the "perfect" decision and creates space for rapid learning.
To avoid getting stuck in perfectionism or endless analysis, a few simple principles can help:
Use timeboxing. Set clear limits on how much time you spend researching and making a decision. Not every question deserves unlimited attention.
Reduce your options. Too many alternatives make decisions harder. In many situations, choosing between two or three realistic options is enough.
Accept "good enough." Perfection is rarely necessary for the next step. What matters is having enough information to make a well-informed decision.
Define the next small step. Big goals can feel overwhelming. Small, concrete actions create momentum and keep the process moving.
For Josua, this has been one of the most important lessons of entrepreneurship: learning to recognize when additional work no longer creates meaningful value, and having the confidence to stop.
Great Decisions Start with the Founding Team
Individual decisions matter, but the team making them matters even more. Choosing your co-founders is one of the most consequential decisions you'll ever make. Clearly defined roles, transparent responsibilities, and a shared approach to dealing with uncertainty provide the foundation for making good decisions even under pressure.
Ultimately, successful founders don't make better decisions simply because they know more. They make better decisions because they are willing to act despite incomplete information, continuously test their assumptions, and adjust their course whenever new evidence emerges.
Scientists are particularly well equipped for this challenge. Anyone who has learned to formulate hypotheses, design experiments, and learn from results already possesses many of the core skills of entrepreneurial thinking. The crucial difference is that the experiment is no longer confined to the laboratory but is happening in the marketplace.
Every breakthrough begins as a spark. What matters is how you develop it and who supports you along the way.
