What Entrepreneurs Can Learn from Range

Startup culture rewards a clean story: find your niche, commit hard, and never look back. But investors, accelerators, and pitch-deck advice often push founders to lock into one business model, market, or customer segment before there's been time to test whether it's actually the right one — and any later change of direction gets read as a founder who "didn't do their homework" rather than one who learned something real. That pressure can push you to defend a first guess long after the market has started telling you something different.

This edition works through 4 core lessons — take them one at a time, not all at once.

02 · Where Are You Now?

What's different for your conditions

Tap whichever ones sound like you. Nothing here is sent or saved — it's just for your own noticing.

Runway is finite, so sampling costs real money and time, not just curiosity.
Investors often want a single clear thesis before you've had a real chance to test it against customers.
Early hires and public messaging lock you into describing the business as more fixed than it actually is.
Competitors who look more "focused" can create pressure to commit prematurely.
Market feedback in year one is often slow, noisy, or contradictory, making it hard to tell a bad idea from a good idea poorly executed.

03 · Core Lessons

The core lessons, applied to you

Rethink "pick A Lane

Rethink "pick a lane and never look back"

The idea

Committing hard and fast to one plan works well in stable, well-understood markets, but in a new venture — where you're still learning who the customer actually is — locking in early can mean building on a guess before you've gathered enough evidence to know if it's wrong.

What it looks like

A founder builds a scheduling app for one narrow vertical and stays committed to it for two years past the point where usage data, churn, and sales calls all pointed somewhere else, because switching felt like admitting the original plan had failed.

Try this

At the start of a new push, write down what evidence over the next 90 days would tell you to change course — so a shift later reads as following the data, not caving to doubt.

Run Small

Run small, cheap experiments before betting the company

The idea

Treat your first business model as a hypothesis, not a commitment. Structure early spending so you can test a few variations of your offer, customer, or channel before scaling any single one.

What it looks like

A founder spends a full year of funding building the complete version of one product for one customer segment, only discovering in month eleven that a different segment was buying it for a completely different reason than intended.

Try this

Before your next major spend, list three different customers or offers you could test cheaply this month, and run at least one before committing the full budget to any of them.

Bring In What You Learned

Bring in what you learned somewhere else

The idea

Experience from a past job, a hobby, or a stint in an unrelated field often contains exactly the pattern-matching your venture needs, even when it doesn't look like "industry experience" on paper.

What it looks like

A founder with a background in restaurant logistics dismisses it as irrelevant to her new software company, then spends months rediscovering inventory principles her old job had already taught her the hard way.

Try this

List two skills or patterns from a job or hobby with nothing to do with your current business, and ask where they might solve a problem you're stuck on right now.

Be Willing To Change Direction

Be willing to change direction

The idea

Pivoting a business model, a market, or even the core of the venture, once you have real evidence it doesn't fit, is a form of applied learning rather than a wasted year — many ventures that eventually work are shaped substantially differently from their first version, and the early effort is what made that later shape possible.

When the clusters compete

You need to look decisive and consistent to investors and employees, but you also need to stay genuinely open to pivoting. Hold both by being transparent that you're testing specific assumptions on a set timeline, rather than either projecting false certainty or looking like you're flailing.

04 · Choose Your Priority

Name one thing, honestly

What is one assumption about your business that you have never actually tested against a real customer?


Good. Now look back at the "Try this" line under whichever lesson feels most connected to what you just wrote, and treat that as this week's actual assignment — not all 4 at once.

05 · Put It Into Practice

The practices from this edition

At the start of a new push, write down what evidence over the next 90 days would tell you to change course — so a shift later reads as following the data, not caving to doubt.
Before your next major spend, list three different customers or offers you could test cheaply this month, and run at least one before committing the full budget to any of them.
List two skills or patterns from a job or hobby with nothing to do with your current business, and ask where they might solve a problem you're stuck on right now.
