The early days of a business run on pure adrenaline. You have an idea and you go with it. Every decision comes from your gut. You know your customers because you talk to every single one of them.

Then success happens.

It’s intoxicating at first, but then… things get noisy. You have more customers than you can remember by name. Revenue grows, but so does complexity. Your crystal-clear intuition starts to get fuzzy.

I know that feeling. It’s the seeds of self-doubt and anxiety that arise from flying blind, once the plane gets bigger.

I promise: you aren't losing your touch. You're simply outgrowing your toolkit.

The skills that built the business are different from the skills required to scale it. You need a new way to see what's happening. A way to turn the noise back into signal.

This is where we embrace the numbers. Gut feeling got you here, but data propels you forward. It gives you your confidence back. Proves that your success is both real and repeatable.

Today’s leaders face multiple, intersecting crises, from geopolitical conflicts to climate change and technological disruption. In this article, CEOs and Harvard Business School experts share six strategies for turning disruption into opportunity. You will learn:

Our story begins in a familiar setting. One person, a belief, and a series of experiments. 

Lane Wagner knew the way coding was taught needed to change. 

As a senior backend engineer, he saw people enter the workplace without the foundational knowledge they needed to move forward. Though there were myriad ways to learn this stuff, people didn’t. He launched Boot.dev to target this friction.

At launch, he had a simple, intuitive mission: make backend engineering accessible.

For two years, he built the product he would have wanted. He built an efficient library of content. Assumed that if the information was good, students would stick around.

He made it to $1k revenue per month, then the business got stuck. His intuition started the engine, but the car refused to move.

Wagner did some diagnostics, and determined there were two truths holding him back:

Armed with this knowledge, Wagner formed a hypothesis: learning to code should feel like playing a game.

He concentrated his efforts on proving out this hypothesis. To do so, he had to figure out the single most important metric to look at. He needed a North Star. 

Rather than obsessively checking vanity metrics like total signups and non-recurring revenue, he obsessed over a single number: lesson completion rate.

He gamified the entire platform. Users earned XP, collected items, and leveled up. He tracked the specific “difficulty score” of every coding challenge. If the data showed users quitting at Level 5, he fixed Level 5.

He still leaned into his intuition, to set the theme. But, importantly, he let the data build the product.

The results were astounding. As a result of Wagner’s new quest, Boot.dev jumped from a $1k/mo side project to a $350k/mo juggernaut.

Wagner’s Founder skill leveled up. He had stopped guessing about what his users wanted, and started tracking what they actually did.

Use your gut to choose the mountain. Use the data to climb it.

I find that most early-stage founders adopt one of two approaches, depending on their personal inclination:

If you’re a Renegade, I trust it’ll be difficult to persuade you to change until your business stagnates. If you’re a Robot (like me), I know you’ll have trouble letting go of the numbers that look good, even when they don’t move you forward.

In either case, I beseech you to put your ego aside if you want to scale.

You need to simplify.

Effective scaling requires ignoring 90% of your available data to focus intensely on the one metric that drives your business forward.

Use this simple Bottleneck Audit to identify yours.

Every stalling business has a singular, most important root cause. Ask yourself where the chain breaks.

Once you identify the constraint, assign a single metric to it. This becomes your North Star for the next 90 days.

Do not build a complex dashboard. Do not start convincing yourself that you need to subscribe to expensive analytics software.

Just write your North Star on a sticky note. Stick it to your monitor. Update it every Monday morning.

If a task moves that number, do it. If it doesn't, deprioritize it.
