Why Startups Burn Billions

Read in·

In 2024, venture-backed startups raised over $300 billion. Most of them were losing money.

This was the plan.

I've been trying to understand the logic behind this for a while. At first it sounds like collective delusion — thousands of smart investors choosing to fund companies that spend more than they earn, at scale, on purpose. But once you see the underlying math, it becomes almost obvious.


Imagine you spend $700 to acquire a customer. She pays you $100 a month and stays for three years — $3,600 total. Five times what you spent.

You "lose" money for the first seven months of that relationship. Then you earn, for the next twenty-nine.

The math works. It works so well that the only intelligent thing to do is acquire as many customers as fast as possible, even if each one looks like a loss at first. The planting season always looks expensive. That's what planting seasons are.

But here's where it gets interesting.

The benchmark for healthy unit economics: lifetime value should be at least 3x the cost to acquire each customer.

Every month you don't have her, she might become someone else's. And in some markets, that's not just a missed sale — it's a permanent structural disadvantage.


Some products get better the more people use them.

A ride-hailing app with more drivers means shorter wait times. Shorter wait times attract more riders. More riders mean more income for drivers, which attracts more drivers. The cycle reinforces itself. The bigger the network, the harder it is to displace — not because the product is better in some absolute sense, but because the network is the product.

In markets like this, being second is nearly worthless. The leader captures most of the profits. Everyone else fights for scraps.

Uber understood this early. The company raised $13 billion in venture capital and lost over $30 billion across 60+ countries — subsidizing rides below cost, city by city, for years. Not because the economics were broken. Because the economics only work at scale, and getting to scale required surviving a long, expensive war.

Uber posted its first operating profit in 2023. Fourteen years after it was founded.


But the logic has a shadow side.

Not every market has winner-takes-all dynamics. Not every loss is an investment. And when those two things get confused, the results are spectacular.

WeWork raised $12.8 billion at a $47 billion valuation. The company was losing more money than it earned — $3.9 billion in losses against $3.5 billion in revenue. The CEO bought a private jet and sold the company the naming rights to his own initials. The IPO collapsed. The company went bankrupt.

The difference between Uber's burn and WeWork's burn isn't the size of the losses. It's whether each dollar spent is building something that compounds — a larger network, a lower cost structure, a flywheel that gets harder to stop. Uber was buying market share in a business where market share changes the product. WeWork was leasing expensive offices and calling it a technology company.

Reid Hoffman called the right version of this "blitzscaling." He also warned: if you're burning cash without extraordinary growth rates, "you're not blitzscaling. You're just burning cash."


For a few years around 2020 and 2021, the distinction got blurry.

Interest rates near zero meant investors couldn't earn real returns on safe assets. Capital poured into anything that looked fast-growing. Global venture funding peaked at $681 billion in 2021. Valuations drifted away from any anchoring logic.

Then rates rose. Funding fell by more than half. Companies that had never thought seriously about profitability were suddenly asked to demonstrate it. Over 260,000 tech workers were laid off in 2023. The WeWorks disappeared. The Ubers and DoorDashes — which had been burning well, building genuine scale advantages — survived and emerged profitable for the first time.

The correction didn't disprove the logic of losing on purpose. It just clarified when the logic applies.


The underlying math hasn't changed. In markets where scale compounds and winners capture most of the profits, spending aggressively to get there first is rational — sometimes the most rational thing a company can do.

What changed is the assumption that every market works this way.

Most don't. A network that compounds, a product that improves with every new user, a cost structure that bends downward at scale — these are specific conditions, not universal ones. They describe some markets clearly. They describe most markets not at all.

The question worth asking isn't whether losing money can be smart. Sometimes it can.

The question is whether the market you're entering is actually a race with one winner — or whether you're just spending money and calling it strategy.
