📘Knowledge Drop: The Importance of Unit Economics
A company spends $50 to acquire a customer who pays $100 back. That's a nice 2x return.
That sounds exciting, but if you see this you should be nervous.
This is called unit economics
Unit economics is simply about how much money a company makes on each customer.
It's the math between two numbers:
CAC (Customer Acquisition Cost): What they spend to get one customer
LTV (Lifetime Value): What that customer pays them over time
Example: A company spends $50 on ads to get a customer. The customer buys once for $30 then never comes back. In this case, the unit economics are broken because the company loses money on every sale. This means the business will never be profitable.
Same $50 on ads, but the customer pays $200 over their lifetime through repeat purchases. Unit economics works because the company profits $150 per customer.
Why this matters for you: If the company loses money on each customer, scaling just means losing money faster. Your investment helps them dig a deeper hole.
If they make money on each customer, growth works. This is the foundation your investment is built on.
The problem with "good enough" unit economics
That company with $50 CAC and $100 LTV sounds fine until you realize customer acquisition costs almost always go up.
Early customers are cheap. They come from the founder's network or referrals. Then the company tries to grow and now they're competing against companies with big budgets, hiring salespeople, paying premium rates for ads.
Six months later that $50 CAC is $80. A year later it's $120. If the business only works at $50 CAC, you just invested in something that's already on its way to going down hill.
What you should be looking for
If a company shows you $50 CAC and $100 LTV and feels good about it, but you should be asking lots of questions.
What happens when CAC hits $100, $200 or even $300? Will the business model still work or does it collapse? If it collapses, you're not investing in a sustainable business.
Why big failures happen
You see headlines about startups that raised $200 million and then closed down. When you dig into what happened, it's usually the same story, the unit economics never made sense from the beginning.
What has usually happened in these cases is that the companies were spending money slower than they could make money or raise money. And eventually they ran out of cash.
What you should look for
Look for companies that make their money back in the first transaction. Example..they spend $50 on marketing, $30 on product costs and the customer pays $100. That's a $20 profit immediately, before you even the repeat purchases.
Not "we break even in 12 months." Not "we'll be profitable eventually." Profitable right now, from day one. That gives them cushion when CAC goes up.
Decent unit economics is a tightrope walk that most companies can't pull off so stay away from them.
What this means when you're investing.
Don't just verify that the math works today. Ask whether it can survive CAC doubling or tripling. Ask what happens when growth gets expensive and competitive.
The companies worth backing aren't the ones that need everything to go perfectly. They're the ones with fundamentals strong enough to take hits and keep working. And those are the companies you should invest in.
