The Dawn of the AI Builder, and how to become one - Deb Liu & Marily

Work is changing — fast. The builders win now.

Not long ago, building a product felt well-defined. PMs owned the roadmap, designers crafted flows, UXR validated needs, and engineers stitched it all together. Everyone had a lane. Today, the lanes are blurring and in some cases, gone completely.

I’ve spoken with CEOs who’ve eliminated entire layers of PMs, founders who say designers “run the show,” and leaders who quietly admit: roles aren’t what they used to be. At first these stories sound extreme. But zoom out, and they point to something bigger: the product org as we know it is collapsing — and at the center of that collapse is AI.

Suddenly, leaders were making massive changes to the field. One incoming CEO fired his PMs and had designers and engineers step in. Another head of a large division said she replaced most of her PMs because they were just turning the crank when she needed builders. A founder said they combined design, product, and product marketing into one.

Alarming? Maybe. But the truth is, the product roles we once knew are evolving.

Why this moment feels different

A founder put it to me this way:

“There will be people building with AI, and people who aren’t. And if you’re not, you won’t be building at all.”

It’s a stark, polarized view — but it captures what’s at stake. Just as the internet and mobile once defined who could compete, AI is drawing a new line in the sand.

• On one side: those who learn to orchestrate these systems — turning ideas into prototypes, prototypes into products, and products into companies.

• On the other: those who wait, watch, and eventually get left behind.

The rise of the AI Builder isn’t just about efficiency but it’s more about survival.

When AI redrew the map

Over the past two years, AI has quietly eaten away at the boundaries between roles. Tools can generate wireframes, draft copy, scaffold code, and even spin up prototypes. What once took weeks of coordination can now be done in a single afternoon, by one person and a laptop.Instead of specialization, we’re seeing convergence. PMs aren’t limited to specs. Designers aren’t limited to mockups. Researchers aren’t limited to reports. Anyone with a sense of the problem can start building the solution.

And out of this convergence, a new archetype has emerged.

Enter: The AI Builder

The AI Builder isn’t a PM with extra tools, or a designer dabbling in code. It’s something new.

The AI Builder is someone who orchestrates a constellation of AI systems to go from idea → prototype → live product.

The AI Builder isn’t simply faster at executing. What sets them apart is how they think. Traditional product development was built for a deterministic world, where rules and processes guided every step. Building with AI is different: it’s non-deterministic. Things break, outputs surprise you, and success depends less on rigid specs and more on setting the right goals and guardrails. The AI Builder thrives in this ambiguity.

Picture this: you describe an idea. One AI tool drafts the PRD. Another turns it into wireframes. Another builds a prototype. Yet another converts it into working components. Finally, a deployment tool stitches it into an app customers can actually use. Days later, you’re live. That’s the superpower of the AI Builder.

Prototyping the vibe

For decades, PMs primarily communicated ideas through text — PRDs, specs, docs. But writing isn’t always the fastest or clearest way to align a team.

With AI, you don’t just describe the idea. You show it. This shift — call it vibe prototyping — lets PMs and non-PMs create quick interactive artifacts that capture the “feel” of a product. These aren’t production-ready. They’re conversation starters. They make the vision tangible enough that others can react, refine, and rally around it.

The workflow itself is evolving:

• Traditional: Idea → PRD → Debate → Refine → Build

• Emerging: Idea → Brainstorm with AI → Prototype the vibe → Team experiences it → Refine → Build

For complex projects, documents still matter. But for many ideas, the prototype itself is the spec.

Today’s builders face a new pain: not knowing what or why to build.

The possibilities feel infinite, and without the right frameworks it’s easy to fall into the trap of spinning out demos that never find traction. The AI Builder rises above this by combining product taste with second-order thinking — asking not just “how do I build this feature?” but “what does this unlock that changes the game?” In a world of democratized technology, the differentiator isn’t who can code faster. It’s who can make the smarter bets.

Why the dawn of the AI builder matters

If you zoom out, the implications are huge:

• For PMs: The role shifts from spec-writing to actually launching.

• For designers: The Figma-to-code gap is closing.

• For engineers: Routine coding is being commoditized, but engineers who partner with AI Builders will become force multipliers.

• For companies: Product cycles compress. The distance between idea and customer feedback shrinks.

The bigger movement

Bootcamps are already forming to train AI Builders. Enterprises are experimenting with letting non-engineering teams ship their own tools. Communities are forming around “AI-first” startups.

We’ve seen this movie before: Shopify turned anyone into a merchant. YouTube turned anyone into a creator. Now, platforms like the tools above are making it possible for anyone to be a builder.

Looking ahead

The old product org isn’t dying — it’s evolving. The AI Builder is its next chapter.

And the question isn’t if this archetype will dominate, but who will step up and claim the mantle.
