Build Things That Don't Scale: The Counterintuitive Startup Advice

"Do things that don't scale." It's the most famous piece of startup advice, courtesy of Paul Graham. And it contradicts everything engineers are taught. We're supposed to build for scale. Automate everything. Plan for millions of users. Graham says: forget all that. At least at first.

The Paradox of Early Startups

Here's the uncomfortable truth: most startups fail not because they can't scale, but because they never find something worth scaling. They build elaborate systems for users who don't exist. They optimize for problems they don't have.

The goal of an early startup isn't to handle a million users. It's to find ten users who love you. Everything else is premature.

What "Doesn't Scale" Actually Means

Stripe's founders manually onboarded early users. They'd visit offices, sit with developers, and integrate Stripe themselves. This is insane from an efficiency standpoint. But it taught them exactly what developers needed.

Airbnb's founders went door to door in New York, taking professional photos of listings. They couldn't hire photographers at scale. But those better photos increased bookings dramatically, proving the concept worked.

DoorDash founders delivered food themselves before building any driver network. They'd take orders, drive to restaurants, drop off meals. Totally unscalable. But they learned the business inside out.

Why Manual Work Beats Automation Early

You learn faster. Automated systems hide problems. Manual work exposes them. When you're personally onboarding users, you see every friction point, every confused expression, every drop-off moment.

You build relationships. Early users who get personal attention become evangelists. They feel ownership. They forgive bugs. They tell friends. You can't automate genuine human connection.

You stay flexible. Automated systems are expensive to change. When you're doing things manually, pivoting is cheap. Discover users want something different? Adjust tomorrow.

You validate before building. The manual version tests whether anyone wants the product before you invest in building it properly. Many startups discover their original idea doesn't work—better to learn that with a hacky prototype than an elegant system.

The Recruiting Mindset

Paul Graham describes early user acquisition as "recruiting." You're not just marketing to an audience. You're personally convincing individuals to try something. This feels wrong to engineers. Shouldn't the product speak for itself?

Not at first. At first, your product is rough. The value isn't obvious. Users need convincing. They need hand-holding. They need to be shown why this thing matters.

Later, word of mouth and organic growth can take over. But you need those first few users to generate any word of mouth at all. And you get them by recruiting, not broadcasting.

The Danger of Premature Scaling

Premature scaling is the silent killer of startups. It looks like this:

• Building a Kubernetes cluster before you have 100 users
• Implementing a microservices architecture for a product still finding market fit
• Hiring a sales team before you understand your sales process
• Building an admin dashboard before you know what metrics matter
• Creating automated onboarding before you know what users need to learn

Each of these seems responsible. You're planning ahead! But each one costs time and money that should go toward learning. And each one creates inertia—once you've built the system, you're reluctant to throw it away even when the product needs to change.

When to Start Scaling

So when do you transition from things that don't scale to things that do?

When you're turning away users. If demand exceeds your manual capacity, that's a good problem. Scale enough to meet demand, no more.

When you've found product-market fit. When users love your product and tell others unprompted, when retention is strong, when you understand exactly why people use you—then scale. Not before.

When the patterns are clear. Manual work should reveal patterns. "Users always ask about X during onboarding." "The first thing people want is Y." When patterns emerge, you can automate them confidently.

The Counterintuitive Lesson

Great startups look like terrible businesses early on. Their unit economics don't work. Their processes are manual. Their founders do jobs they should hire for. By traditional business metrics, they're failing.

But they're learning. They're iterating. They're finding the path to something that does scale. The messy early phase is how you discover what to build.

The alternative—building the "right" way from the start—means building confidently in the wrong direction. You'll have beautiful code and elegant architecture for a product nobody wants.

Do things that don't scale. Learn what matters. Then build it properly.
