Missing a major investment opportunity taught me that waiting for complete certainty can be more costly than making a thoughtful decision with limited information.

Early in my investing career, a friend introduced me to a small trading app. At the time, the company had little revenue, barely any users and a valuation that seemed far too high for its current position.

I hesitated. I wanted stronger evidence, more reliable data and clearer signs that the business would succeed. I convinced myself that waiting would eventually give me the information I needed.

That company was Robinhood.

Watching it grow forced me to recognize an important truth: complete clarity is often an illusion. In early-stage investing and entrepreneurship, the most important decisions usually have to be made before all the answers are available.

Markets change, customer behavior evolves and new competitors appear. By the time the evidence feels undeniable, the opportunity may already be gone.

Why uncertainty should not automatically stop progress

Businesses often lose momentum when leaders treat uncertainty as a reason to delay. The fastest-growing companies are usually led by people who understand that clarity does not always come before action. In many cases, clarity is created through action.

Rather than waiting until every question is answered, effective leaders move forward once they have enough evidence to form a reasonable level of conviction.

I call this approach One Sigma Confidence.

What One Sigma Confidence means

The idea is inspired by statistics, but the principle is straightforward: once you are approximately 70% confident in a decision, it may be time to move.

This does not mean acting recklessly or ignoring legitimate risks. It means making a grounded decision based on what you know, what you reasonably believe and what remains uncertain.

Early-stage companies rarely have complete data. Entrepreneurs and investors must often evaluate opportunities using incomplete information, limited customer feedback and developing market signals.

One Sigma Confidence creates a useful balance. It encourages timely action without promoting careless decision-making.

The hidden cost of overthinking

Over-analysis can appear responsible, but it is often fear disguised as discipline.

Founders delay launches because they want perfect customer feedback. Investors continue asking for more evidence even after their main concerns have been addressed. Employees avoid making decisions because they want someone to guarantee the outcome.

The consequences are not always immediate, but they eventually become visible. Momentum disappears, competitors release products, promising opportunities move on and investors shift their attention toward founders who are making progress.

A flawless plan that never leaves the drawing board is rarely more valuable than an imperfect plan that produces real feedback.

People who move forward understand that incomplete information is not necessarily a problem. It is a normal part of creating something new.

When 70% confidence was enough

One of my most successful investments came from a situation in which many questions remained unanswered.

I was evaluating a robotics company using a framework that considered the strength of the team, the quality of the idea, the valuation and how closely the opportunity aligned with my investment strategy.

The company’s overall score crossed my required threshold, although I still did not have every detail I wanted.

However, I believed the founder had the right personality and leadership ability. The company was addressing a genuine problem, and the early indicators were promising.

That was enough for me to act.

Years later, John Deere acquired the company for $250 million.

That investment reinforced the lesson I learned from passing on Robinhood. Acting with 70% confidence is not the same as gambling. It is a structured way of pursuing opportunities that are unlikely to arrive with complete certainty.

Action creates information

Strong judgment is not developed by waiting indefinitely. It grows through taking action, observing the results and adjusting based on what happens next.

Every conversation with a customer, product test, early sale, investor meeting and business experiment provides useful information. Patterns become clearer once a company begins interacting with the real world.

Founders who act with sufficient confidence can often adjust more quickly because they are working with actual feedback rather than relying entirely on forecasts and theories.

Their teams remain motivated because progress is visible. Investors also gain confidence because company updates are based on real activity instead of speculation.

The same principle applies to investment decisions. Investors who depend only on presentations, projections and financial models may overlook qualities that become clear through direct interaction.

Meeting the founder, observing how they respond to challenges and evaluating their ability to follow through can reveal more than another round of analysis.

Movement often uncovers important signals faster than planning alone.

How investors can apply the 70% rule

For investors, One Sigma Confidence can reduce emotionally driven decisions. Instead of making choices based entirely on excitement, fear or instinct, investors can rely on a consistent evaluation system.

A framework might score factors such as:

• Leadership and team quality
• Strength of the business idea
• Valuation
• Market opportunity
• Strategic alignment

The goal is not to make the correct decision every time. No investment framework can guarantee that. The goal is to make decisions with consistency and discipline.

The approach can also improve portfolio management. Investors can regularly classify companies into green, yellow and red categories based on their performance and risk level.

Over time, these evaluations improve pattern recognition. Investors become better at identifying which founders need additional support, which businesses require intervention and which companies may no longer be able to recover.

Instead of reacting emotionally to every development, investors establish a steady process for reviewing progress.

How founders can apply the rule

For founders, the 70% rule provides permission to move before everything feels comfortable.

Strong leadership does not require pretending that uncertainty does not exist. It requires making timely decisions, communicating what is known and remaining honest about potential risks.

Teams are often capable of handling uncertainty when their leaders provide clear direction. Investors also tend to respect founders who take action, address concerns early and make thoughtful adjustments.

Seventy percent confidence often feels like having enough clarity to move forward while still recognizing that some questions remain unanswered.

It may not feel comfortable, but comfort is not the goal.

Once the available evidence crosses a reasonable threshold, continued hesitation may no longer improve the decision.

Clarity develops through movement

One Sigma Confidence is a skill that becomes stronger through experience. It requires leaders to review their decisions honestly, learn from the results and improve their judgment over time.

The principle does not eliminate uncertainty. Instead, it teaches investors and founders how to respect uncertainty without becoming controlled by it.

The businesses that grow are often led by people who understand when to analyze, when to adapt and when to move.

They do not wait for perfect clarity. They create clarity by taking the next thoughtful step.
