After years of building software for other companies, we’ve noticed a pattern: the products that survive, scale, and stay pleasant to work on are almost always the simplest ones that could have done the job. Simplicity isn’t a style preference at Loopjet — it’s the engineering principle that everything else depends on.
Complexity is the default, and it’s expensive
Nobody sets out to build a complicated system. Complexity accumulates one reasonable-sounding decision at a time: an extra configuration option here, a speculative abstraction there, a microservice split before there’s anything micro about the team. Each addition feels cheap. Together they create real costs:
- Slower changes: every new feature has to thread through more moving parts
- More failure points: complex systems break in ways nobody predicted
- Harder onboarding: each new engineer pays the complexity tax again
- Costlier operation: more services, more dashboards, more 2 a.m. surprises
Across the systems we run — used by over five million people — the simple ones are the reason we can promise 99.8% uptime. Complexity is where downtime hides.
What simplicity actually means
Simplicity is not building less than the problem needs. It’s refusing to build more than the problem needs. In practice, that looks like a few recurring decisions:
- Start with the smallest thing that solves the problem well. You learn more from two weeks of real usage than from two months of speculative architecture.
- Choose boring technology for the critical path. Save the experiments for places where failure is cheap.
- Delete as a feature. Code that no longer earns its keep gets removed, not commented out.
- Make the design match the domain. If you can’t explain the architecture to the client on one whiteboard, it’s probably wrong.
- Say no early. The cheapest feature to maintain is the one you talked someone out of.
Simple for users, too
The same principle drives our interface work. Modern, minimal design isn’t fashion — it’s respect for the user’s attention. Every screen should make the next step obvious. When a product feels effortless, it’s usually because someone did the hard work of cutting everything that didn’t matter.
The discipline is saying it out loud
The hardest part of simplicity is that it requires honest conversations. Sometimes the most valuable thing we tell a client is “you don’t need that yet.” It can feel strange coming from the people who would be paid to build it — but it’s exactly why our clients stay.
If you want a team that will argue for the simpler version, we’d love to hear about your project.
