A few years ago I was sitting with a founder who had just closed their first real round of funding.

It wasn’t a massive Series B or anything like that. This was early stage. A solid seed round. Enough capital to hire a few people, build product, and start figuring out whether the business actually worked.

The team was smart. The product looked promising. The market opportunity was real.

Then we opened the financial model.

Or rather, we tried to.

There wasn’t one.

When I asked about it, the founder shrugged and said something I’ve heard more times than I can count:

“One of our investors told us early-stage financial models are just poetry.”

The logic sounded reasonable on the surface. Early-stage startups are unpredictable. Revenue projections are guesses. Markets shift. Products pivot. Because of that uncertainty, the numbers supposedly don’t matter.

Just focus on the product. Focus on the vision. Focus on building.

The founder wasn’t being careless. They were repeating advice they had been given by someone they trusted.

But that advice is one of the most damaging ideas circulating in early-stage venture today.

The “Founder-Friendly” Shortcut

Over the past decade, a certain style of venture investor has become increasingly popular.

They brand themselves as “founder-friendly.” They promise quick decisions, minimal diligence, and high conviction. They proudly say they invest based on the founder and the vision rather than spreadsheets.

For early-stage founders, that pitch can sound incredibly appealing. The fundraising process is already stressful and time-consuming. An investor who claims they don’t care about financial models feels like a breath of fresh air.

But in practice, this attitude often crosses a dangerous line.

It starts with statements like:

“Financial models are just poetry.”

What that phrase really means is that early-stage founders shouldn’t bother thinking too deeply about the financial mechanics of their business.

And that’s a mistake.

Financial Models Are Not Revenue Forecasts

The core misunderstanding behind this advice is simple: people confuse financial models with revenue forecasts.

Yes, early-stage revenue projections are speculative. Anyone who has worked with startups understands that. No one expects a pre-seed company to accurately predict revenue three years into the future.

But revenue projections are the least important part of a financial model.

The real purpose of a model is to understand the mechanics of the business itself.

What does it cost to acquire a customer?

What does it cost to deliver the product?

How do margins change as the company grows?

How many customers are required to support the team?

How long will the company’s runway actually last?

These questions are not theoretical. They are operational.

And the earlier founders start answering them, the better.

Early Stage Is Exactly When This Matters

Ironically, the stage at which investors dismiss financial models is exactly the stage when founders need them most.

At the early stage, almost everything about the company is uncertain. Product-market fit is unclear. Customer behavior is still emerging. The go-to-market strategy is evolving.

That uncertainty makes it even more important to understand the basic economic assumptions behind the business.

A financial model forces founders to ask questions that are easy to avoid in the excitement of building a new product.

Is the cost of acquiring customers sustainable?

Does the product become profitable as usage scales?

Is the team hiring ahead of revenue, or building ahead of demand?

How much capital will it actually take to learn whether the business works?

Without a model, those questions often go unexamined until the company runs into trouble.

The Unit Economics Trap

One of the most painful lessons founders learn is that growth can hide broken economics.

A company can grow rapidly while losing money on every customer, especially if early growth is supported by venture capital or aggressive marketing spend.

Eventually the math catches up.

The startup ecosystem has seen this pattern many times.

MoviePass offered unlimited movie tickets for $9.95 per month while paying theaters the full retail price for each ticket. The product was extremely popular because customers received far more value than they paid for. But every time a user went to the movies, the company lost money. The more successful the product became, the faster the company burned through cash.

Homejoy faced a similar issue in the on-demand services market. The company raised more than $40 million and grew rapidly, but the economics of the cleaning service depended heavily on subsidies and contractor labor dynamics that proved difficult to sustain. Eventually the business shut down despite strong demand.

Even companies that ultimately survive can struggle with this dynamic. Uber’s early expansion relied heavily on subsidies for both riders and drivers. Those incentives accelerated adoption but also produced billions in losses. Uber eventually adapted its model, but the early years illustrate how easily growth can outpace sustainable economics.

These examples are large and visible, but the same pattern plays out quietly in early-stage startups every year.

Understanding the Machine You Are Building

A thoughtful financial model forces founders to understand the machine they are building.

It requires them to think through their cost structure, operating expenses, unit economics, and capital requirements.

It forces clarity around questions like:

How many customers do we actually need?

What does success look like economically?

How much money do we need to learn whether this works?

Those questions are especially important at the early stage because the company still has the flexibility to adapt.

Once a company has scaled a flawed model, the options become much more limited.

Startups Are Also Fiduciary Responsibilities

Startups are often described as ideas or experiments.

But they are also fiduciary responsibilities.

When investors wire money into a company, they are trusting the founder to allocate that capital thoughtfully. A financial model is one of the clearest ways a founder can demonstrate that they have considered how that capital will be deployed.

Models allow founders to test hiring plans, marketing investments, and growth assumptions before committing real money.

Without that framework, founders are effectively operating without a budget.

And that is not founder-friendly advice.

It is irresponsible.

Models Are a Tool for Adaptation

No early-stage financial model will be perfectly accurate.

Assumptions will change. Markets will evolve. Products will pivot.

But that doesn’t make models useless.

It makes them useful.

A model provides a baseline set of assumptions about how the business should behave. As the company learns more about customers and the market, those assumptions can be updated and refined.

In that sense, financial models are not static predictions.

They are learning tools.

They help founders understand the relationship between growth, cost, and capital.

And they help founders make better decisions as the company evolves.

What these VCs are really saying...

When someone dismisses early-stage financial models as “poetry,” what they are really saying is this:

“We don’t care whether you understand your business.”

That might feel founder-friendly in the moment.

But founders who ignore the economics of their business eventually have to learn them the hard way.

And by then, it is often too late.
