People often say "hop on the rocket."
It means ride along with a fast-growing company and grow together. But then these thoughts cross your mind:
- 'Is the rocket I'm riding actually taking off, or is it about to crash?'
- 'Will this company even exist a year from now?'
- 'And where is my life heading along with this company?'
A company's survivability is also a safety net for your career. So today, I want to talk about how to find -- and build -- a "company that doesn't fail."
What Failing Companies Have in Common#
The reasons companies fail are surprisingly simple.
- They ran out of money
- They couldn't make money
Just because a company isn't profitable doesn't mean it's about to die.
Like Coupang, some companies sustain long-term losses but survive thanks to growth potential. The key question is: 'We're in the red now, but will we eventually be profitable?' and 'Do we have enough cash to survive until then?'
In other words, failure is ultimately decided the moment cash runs out.
Look at the "Quality of Profits"#
What matters more than whether you're in the red or black is the 'quality of profits.'
That means you need to ask: Is the current structure's profitability sustainable, and does the profit scale as the business grows?
The key concept here is Contribution Margin.
- Revenue - Variable Costs = Contribution Margin
- Contribution Margin - Fixed Costs = Operating Profit
As revenue increases, variable costs (materials, commissions, shipping, etc.) should increase at a slower rate.
A high contribution margin ratio means that when revenue grows, profits grow much faster.
That's why investors always ask:
"As this business scales, does the profit structure improve too?"
Understanding Cost Structure: Variable Costs vs Fixed Costs#
The reason we separate 'variable costs' and 'fixed costs' is straightforward.
- Variable costs: Costs that move with revenue (raw materials, payment processing fees, etc.)
- Fixed costs: Costs that go out regardless of revenue (rent, salaries, etc.)
For early-stage startups, not growing fixed costs is critical.
If you expand headcount or office space before your business model (BM) is finalized, cash depletes rapidly.
Cash Is Truly King#
When judging a company's actual survivability, the Cash Flow Statement matters more than the income statement.
Profit is just a number on the books, but fixed costs are real cash going out every month.
You can calculate the cash depletion period (runway) like this:
Runway = Current Cash on Hand / Average Monthly Cash Burn
Founders should always keep this number in their heads.
To hold onto cash longer, you need to either reduce burn or increase cash inflow.
In other words, spend less and collect receivables faster.
How to Evaluate Intangible Assets and Technical Capabilities#
Patents, brand recognition, data assets, etc. are expressed as Intangible Assets in accounting.
But in the early days of a startup, they don't have much impact on the books.
What investors see as 'technical capability' mostly comes from how quickly, reliably, and efficiently a service actually operates.
Even if it's built on open source, the ability to quickly create a product and improve it based on customer feedback -- that's what early-stage technical capability really means.
The Early Startup Goal Is 'Finding a High Contribution Margin Structure'#
All early-stage strategy should align with this:
- With limited funds
- In the shortest possible time
- Find a structure with high contribution margins that can scale
To do this, you need to build an MVP using Lean Startup methods and iterate with rapid experiments.
Investors also look at whether 'this company is building a structurally profitable model, not just chasing revenue.'
"Companies That Survive" from an Investor's Perspective#
The questions investors ask when evaluating a company are clear:
- Is it making money now?
- Is that structure scalable and sustainable?
- Does it have enough cash to survive for a while?
- Does the founder have a clear picture of the next step?
Founders need to be able to answer these questions to receive investment.
In other words, you need to clearly articulate: "What will we validate with this money?"
Technical Skill, Entrepreneurial Spirit, and Ultimately -- People#
Great technical skill doesn't just come from algorithms or code. It's ultimately accumulated from experience handling scale.
At first, the ability to build fast matters, but later stability and scalability become the focus.
Entrepreneurship is the act of creating new opportunities from a position of limited resources.
This is exactly how Harvard Business School defines 'entrepreneurial spirit.'
And at the center of it all are people.
Communicating well, getting great talent to work together, and delivering value to customers.
That's the real capability of an entrepreneur.
The company you're at right now might be a rocket, or it might be just a spark.
But what really matters is knowing how much fuel that rocket has and how it's being used.
If you're riding someone else's rocket, calculate the survival odds coldly.
If you're building your own, be clear about your fuel (cash), thrust (contribution margin), and target orbit (Product-Market Fit).
That's how you survive in the market.
It has never been my object to record my dreams, just to realize them.
