Embracing Imperfection: The 3-Month Rule for Building Scalable Solutions in Startups
In the world of startups, the mantra “do things that don’t scale” is often echoed, particularly in the tech community, thanks to the insights of entrepreneurs like Paul Graham. However, while many agree with this philosophy, the implementation in the realm of coding is rarely discussed.
Over the past eight months, as I’ve been developing my AI podcast platform, I’ve found a practical approach that I like to call the 3-Month Rule. This framework allows me to test unscalable hacks for a finite period—three months—after which they must either demonstrate their value and be properly developed, or they face removal.
The Startup Mindset: Rejecting Scalable Solutions from Day One
As engineers, we are often conditioned to prioritize building scalable solutions right from the get-go. We focus on complex architectures—like microservices and distributed systems—aimed at accommodating millions of users. However, in the startup environment, chasing scalability too early can lead to costly procrastination. It often means we’re optimizing for hypothetical users who may never materialize, which diverges from the core goal of understanding our actual user needs.
By implementing the 3-Month Rule, I commit to creating straightforward, albeit imperfect, code that can actually be deployed, providing deep insights into user behavior and requirements.
An Overview of My Current Infrastructure Hacks
Let’s take a closer look at some of the unconventional strategies I’ve employed, which I believe showcase the wisdom in simplicity.
1. Consolidation on a Single Virtual Machine
Currently, my entire tech stack—encompassing the database, web server, background jobs, and Redis—operates on a single virtual machine costing just $40 a month. While this setup lacks redundancy and relies on manual backups, it has acutely informed my understanding of resource demands.
In the two months since implementation, I’ve discovered that my resource usage peaks at merely 4GB of RAM. A more complex Kubernetes architecture that I initially considered would have only served to manage empty containers. Not to mention, experiencing outages has illuminated unforeseen vulnerabilities—none of which were on my radar.
2. Hardcoded Configuration Parameters
Instead of implementing traditional configuration management through files or environment variables, I use hardcoded constants throughout my codebase. This may seem primitive, but it offers distinct advantages. I can quickly search for any configuration value, and every change is

This is a really insightful approach that balances the practical needs of startups with long-term scalability considerations. The 3-Month Rule reminds me of the concept of rapid iteration—getting something in front of users quickly to gather real-world feedback before over-engineering solutions. It’s especially valuable in the early stages when understanding actual user behavior trumps theoretical scalability planning.
Your example of consolidating everything on a single VM highlights how spending too much time optimizing for hypothetical peak loads can distract from learning what your users truly need. Similarly, your use of hardcoded configuration parameters emphasizes the importance of simplicity and speed in early development phases, with the understanding that these choices are temporary.
This methodology fosters a culture of experimentation and learning, allowing startups to pivot without being bogged down by unnecessary complexity. I believe that embracing imperfection with intentional constraints—like your 3-month window—can lead to more resilient, user-centered solutions in the long run. Thanks for sharing this practical framework!
