What We've Seen After Building Dozens of Products
Every year, thousands of early-stage software products launch with great enthusiasm, only to stall out a few months later.
When people analyze why products fail, they usually blame marketing or lack of demand. But working directly behind the scenes with founders, we've seen plenty of promising products fail for a purely technical reason: they built the wrong architectural foundation for their current stage.
Here are the hard-earned lessons and mistakes we've observed—and how to avoid them.
1. The Trap of Premature Microservices
A common mistake we see technical founders make is trying to design their V1 application like Netflix or Uber. They split an initial prototype into separate microservices, authentication servers, background processing clusters, and standalone database instances.
What quickly happens is that developer iteration speed drops to a crawl. Changing a single form field requires updating three different repositories, updating Docker configurations, and debugging inter-service network requests.
[Premature Microservices]
1 Simple Feature Change ──> Update Repo A ──> Update Repo B ──> Debug Docker Network ──> 3 Days Wasted
[Modular Monolith]
1 Simple Feature Change ──> Update Function ──> Instantly Deployed in Minutes
OUR RECOMMENDATION
Start with a clean, modular monolith. Next.js App Router lets you keep your codebase organized in clean folders while keeping deployment as simple as a single Git commit.
2. Choosing Superficial Speed Over Basic Quality
The opposite mistake is building an app with zero structure—copy-pasting unvalidated JavaScript snippets and ignoring basic error handling.
This looks like a good idea until real users start trying the product. Unhandled form errors crash the screen silently, missing database indexes cause dashboards to time out, and users quietly abandon the product without telling you why.
The Balance: How We Recommend Building MVPs
Building a successful MVP isn't about writing throwaway code, nor is it about over-engineering enterprise infrastructure. It's about finding the sweet spot:
| Feature | The Fragile Extreme | Over-Engineered Extreme | The INQ Balance |
|---|---|---|---|
| Architecture | Spaghetti JS / No structure | 8+ Microservices | Clean Unified Next.js Project |
| Database | Un-indexed, messy schema | Complex distributed DB | Clean PostgreSQL with basic indexes |
| Validation | None (crashes silently) | Overly complex abstraction layers | Simple Zod schemas at API boundaries |
Summary
If we could give one piece of advice to founders building their first version, it would be this: keep your architecture as simple as possible, but enforce strict type checking and clean boundaries from day one. That way, when your product takes off, your codebase is ready to scale with you.

Frequently Asked Questions
What is the most common technical mistake early startups make?
Premature microservices. Splitting an unvalidated product into multiple independent servers creates massive networking and deployment complexity before understanding user workflows.
