The Scalability Trap: How Premature Technical Excellence Kills the Product

Post image
Like a jet engine strapped to a small car - premature technical excellence is expensive but mostly useless

The “Build it right the first time” mantra has sunk more startups than bad code ever did.

I’ve seen it firsthand: One developer built his own message broker in PHP because ActiveMQ “didn’t fit his needs.” Another rebuilt Ansible in Perl to provision VMs. And the wildest one? Someone started designing a version control system on top of Elasticsearch because Git was “inefficient.”

These weren’t feats of brilliance. They were ego-driven distractions that added fragility, wasted money, and created zero customer value. And they all happened because leadership failed to ask the only question that matters: “How does this help the user?”

Why It Happens

The drivers for “premature optimization”, as tech people say, are actually predictable:

Driver Reason
Ego Engineers want to build impressive systems.
Fear Leaders worry that if they don’t plan for scale now, they’ll pay for it later.
Fantasy Scale Everyone imagines millions of users around the corner. Most never arrive.
Leadership Vacuum Without strong product direction, individuals drift into vanity projects and call it “refactoring.”

The Consequences

Premature “excellence” doesn’t make systems stronger. It makes them fragile. And it derails the business…

Teams lose months while competitors ship. Startups burn through investor capital on infrastructure nobody needs. Complexity increases failure modes, leading to more outages and firefighting. Morale craters when engineers realize they’re maintaining pointless systems. And worst of all, the company misses the opportunity to discover product-market fit, because shipping slowed to a crawl.

How to Avoid the Trap

This isn’t about telling engineers to aim lower. It’s about pointing technical ambition at the right problems.

1. Apply excellence to business problems

Pour your craft into the parts of the product customers actually touch: onboarding, workflows, reliability, collaboration, billing. That’s where engineering skill translates directly into value. By investing in elegant solutions to business problems, you ensure technical excellence is felt by users and tied to outcomes that matter.

2. Ask red-flag questions

Before greenlighting new technical directions, ask:

  • Would customers notice if we didn’t build this?
  • Are we solving a real business problem, or an imagined technical one?
  • Is this the best use of our most talented people right now?
  • Are we taking on complexity that we don’t have the team to support?

3. Use established, battle-proven solutions for the rest

Databases, queues, storage, search — these are solved problems. Don’t waste cycles reinventing them. Borrow stability so you can spend energy where it differentiates. Choosing stability here reduces operational headaches and gives your team freedom to innovate on the product instead of firefighting infrastructure.

4. Balance pragmatism and evolution

It’s not “forty microservices” or “one giant blob.” A good example for a pragmatic middle path is a modular monolith (modulith): one deployable system with clean internal boundaries. Simple to operate today, structured to evolve tomorrow. This balance keeps teams fast without boxing them in, and avoids the premature complexity that kills so many products.

Lessons Learned

Over the years, a few truths have stuck:

  • Some strategic debt is smart
    It’s better to rewrite later than stall today. The key is making debt visible and intentional, so you know why it exists and when to address it. Teams that acknowledge and manage this trade-off often move faster and with more confidence.

  • Scaling is about timing
    With traction, budget and urgency follow. Without traction, nothing else matters. Scaling challenges that come later are a sign of success, and usually easier to solve once the business justifies them.

  • Real excellence = elegant business solutions
    Customers don’t care about your infrastructure diagrams. They care that the product works for them. Excellence here means solutions that are reliable, resilient, and understandable to the business, not just technically impressive.

Closing Thought

The real danger isn’t messy code. It’s burning months — or millions — on complex systems no one needs. Code can be cleaned up, refactored, or rewritten once the product proves itself. But wasted time, burned capital, and lost market opportunity can rarely be recovered.

As leaders, we must keep asking:

Are we building for real customers today, or for imaginary ones tomorrow?

Products don’t die because their codebase was imperfect; they die because they failed to deliver value quickly enough. Technical superiority without customer value isn’t excellence. It’s waste.

In enterprise & solution architecture, connecting boxes with arrows is an often used and overrated visualization from high-level, thru component architecture, down to data and class diagrams. However, to create a holistic view on systems, component diagrams are not enough! When it comes to analysis or transformation of a high-level application- or service-architecture, I prefer to draw an Application Landscape Diagram, which I would like to show and elaborate on in this post.

Securing isolated systems: Caveats of using plain OAUTH flows and how to solve them

While OIDC and OAUTH are well-known standards, they don’t fit every purpose “out of the box.” In businesses with special regulations like banking, health care, etc., non-functional requirements to auth can be challenging. Different solutions and ways were evaluated to create a new identity provider for a medical network. The first approach was “just” using simple OAUTH by its most famous Authorization Code Flow. Of course, it failed fast, and I’ll show why and how we solved it in this post.
