Your TAM Slide is Bullshit

You’re in the room. The lights are down. The air conditioning is humming, and you’re clicking through the deck.

You get to page six. The big one. The Total Addressable Market.

The TAM.

There it is. A circle. A big, beautiful, blue circle.

You’ve labeled it “$50 Billion.” You look the Board in the eye. You tell them this is about “vision.” You tell them this is about “scale.”

You’re lying.

You aren’t showing them a vision. You’re showing them a hiding spot.

You tell yourself that a $50 billion market means there is room for everyone. It means safety. It means if you just capture 1% of the market, you’re a unicorn.

But here is the truth they don’t tell you at YC: In a $50 billion market, 1% is a rounding error. 1% is a statistic on someone else’s spreadsheet.

In a broad market, “1%” means you are invisible.

You aren’t dreaming big. You’re terrified of being small. So you chase after a market size you think will give you cover.

You choose to be nothing.

Why? Because you decided to storm the continent instead of taking the beach.

The Plumbing and the Button

Listen to me.

Microsoft does not care about your “horizontal agentic workflow.” They don’t care about your “AI-native productivity suite.” Why would they? They already own the plumbing. They own the pipes, the water, and the house.

Last November, they didn’t launch a competitor to you. They added a button. A small, grey button in the corner of Word. That button did 80% of what your startup does.

Your “broad market” wasn’t a market at all. It was just Microsoft’s Q4 feature list.

When you pitch a horizontal AI solution in 2026, you’re an unpaid R&D department for the giants.

You’re out there, burning your VC’s cash to prove a use case. And the moment you prove it? The moment that $50 billion market starts to look real?

Click.

The button appears. You’re dead.

The Ghost of 2025: A Case Study in Generic Death

Look at the “Legal AI” wipeout of last year.

Forty startups. Maybe fifty. I lost count. They all had the same pitch. “The AI General Counsel.” “The Future of Law.” They all sounded like they were written by the same marketing intern using the same prompt.

They all went after the “Legal Market.” They all wanted the big, blue circle.

And they all died.

They died because when OpenAI integrated the middleware directly into the enterprise tier, the “General Counsel” bot became a commodity overnight.

If everyone is an “AI lawyer,” then no one is. The price went to zero. The churn went to the moon.

But look at the survivors.

There were three of them. They didn’t pitch the ocean. They pitched the drain.

They didn’t build “AI for lawyers.” They built “AI for high-stakes deposition transcription in maritime law.”

Think about that. Maritime law. Boats. Shipping lanes. Jones Act disputes.

It’s a tiny market. A “small” circle. Your VCs would have laughed at it in 2021.

But guess what?

Microsoft isn’t putting a “Maritime Deposition” button in Word. It’s too specific. It’s too messy.

It requires understanding how a specific group of desperate people actually works.

Those founders weren’t “AI founders.” They were the only solution for a buyer who was bleeding money. They owned the beachhead. They didn’t have competitors; they had a monopoly on a niche.

In 2026, a $500M market you can dominate by Tuesday makes you a threat. A $50B market makes you a statistic.

The $180,000 Monthly Bonfire

You’re burning $180,000 a month. Maybe more. You call it “burn.” I call it vanity.

Where does it go? It goes to an agency. A group of people in expensive sneakers who talk about “Top of Funnel” and “Share of Voice.” They’re buying you a front-row seat to your own funeral.

You’re running LinkedIn ads for “HR leaders” and “Sales VPs.” You want “brand awareness.”

Let’s talk about awareness. A man standing in the middle of a crowded train station screaming, “I HAVE A COG!” has awareness. People see him. People hear him.

They also think he’s a lunatic, and they keep walking.

You don’t have a brand. You have a logo. You have a set of hex codes. You have a generic value prop that says “We automate workflows with AI.”

Who cares?

The giants are already automating workflows. The giants own the workflows.

Every dollar you spend on “general awareness” is a dollar you are giving to your competition.

You are warming up the market so Microsoft can close the deal with a checkbox.

You don’t win a war by attacking a continent. You don’t land your troops across the entire coastline of Europe and hope for the best.

You take one beach.

You find the one group of users whose hair is on fire. You find the one problem that is so specific, so painful, and so “small” that the giants won’t touch it because it doesn’t move their needle.

You narrow the target until it hurts. Then you narrow it again.

Category Design is Capital Defense

Founders think branding is about the “vibe.” They think category design is a marketing exercise you do after you find Product-Market Fit.

They’re wrong. Category design is the floor. It’s the walls. It’s the ceiling.

Category design is capital defense.

In an era where LLMs are a utility—like electricity or water, the only thing that protects your margins is the category you own. If you are “AI for Sales,” you are a commodity. You are competing on price against a thousand other bots. You are a line item waiting to be cut.

But if you create a category—if you are the “Cargo Claims Settlement Engine for Trans-Pacific Logistics”—you aren’t a bot anymore.

You are a business process.

You aren’t selling “intelligence.” You’re selling an outcome. You are selling a world where a specific, expensive problem no longer exists.

This is the difference between a Series B and a quiet fire sale in the middle of the night. It is the difference between being a “feature” and being a “firm.”

If your category is too big to define, it’s too big to defend.

Start the Bleed

You’re going to hate this.

You’re going to walk into the next Board meeting, and your stomach is going to turn. Why? Because you’re going to tell them you’re giving up 99% of the world.

You’re going to start the bleed.

You’re going to take that $50 billion TAM slide, and you’re going to throw it in the trash. You’re going to cut the fat until there’s nothing left but the bone.

You’re going to find that one, narrow, miserable niche where you can be the undisputed king. You’re going to find the beachhead.

Founders are terrified of this. They think “niche” means “small.”

It doesn’t.

Niche means dominant. Niche means defensible. Niche means you have the right to exist when the giants start swinging their weight around.

I help founders find the wedge. We stop the generic noise, and we start the bleed. We narrow the target until the message is so sharp it draws blood from the people who actually need you.

We take the beach. Then, and only then, do we talk about the continent.

You don’t need a bigger market. You need a smaller one that you can actually win.

I help early-stage B2B AI firms find their wedge and defend their category before the giants arrive.
