Embracing the 3-Month Rule: A Practical Approach to Unscalable Solutions
When it comes to building successful tech projects, one piece of advice often resonates among entrepreneurs: “Do things that don’t scale.” This sage insight from Paul Graham encourages startups to focus on immediate user needs rather than get bogged down by the complexities of scaling from the outset. However, the challenge remains: how do you put this approach into practice, especially in coding?
After eight months of developing my AI podcast platform, I’ve devised a straightforward framework that I call the “3-Month Rule.” This rule stipulates that any unscalable hacks I implement are given a three-month lifespan. At the end of this period, the hack either proves its worth and is transformed into a more robust solution, or it is scrapped entirely.
The Problem with Traditional Thinking
As engineers, we often get trained to prioritize scalable solutions right from the start. We dream in terms of design patterns, microservices, and distributed systems—architectural complexities built to accommodate millions of users. However, this line of thinking is more aligned with large companies than with startups.
In a startup environment, focusing on scalability can often lead to costly delays, where we’re preparing for hypothetical users while neglecting the real ones. This is why my 3-Month Rule encourages me to write straightforward, even ‘suboptimal’ code that gets shipped quickly. Through this process, I gain deeper insights into what users genuinely need.
Current Unscalable Strategies: Why They Work
Let’s dive into some of the infrastructure hacks I’ve adopted and examine their unexpected benefits.
1. Consolidating on a Single VM
I’ve placed my database, web server, background jobs, and even Redis on a single $40/month virtual machine (VM). This approach may seem reckless due to the absence of redundancy and reliance on manual backups. Yet, it has offered invaluable insights into my resource requirements within just two months. I’ve discovered that my AI-heavy platform only peaks at 4GB of RAM. The complex Kubernetes configuration I had considered? It would have meant managing empty containers.
When my system has unexpectedly crashed (twice so far), I received genuine data about actual failures—none were what I anticipated.
2. Hardcoded Configuration Parameters
My code features hardcoded constants like this:
“`python
PRICE_TIER_1 = 9.99
PRICE_TIER_2 = 19.99
MAX

This is a compelling approach that emphasizes the importance of prioritizing learning and user feedback over premature scalability. The 3-Month Rule reminds me of the concept of “release early, release often,” where rapid iteration allows you to validate assumptions without being bogged down by over-engineering.
I particularly appreciate the example of consolidating everything onto a single VM—often seen as a “hack” or shortcut—but in reality, it provides crucial real-world data about resource demands and failure modes. These insights are invaluable and often hard to uncover with overly complex or prepared-for-scale architectures.
Your framework also highlights a key mindset shift: embracing “the messy middle” of development where the focus is on learning and iteration. Ensuring that each hack has a clear expiration date prevents stagnation and encourages continuous refinement.
Have you noticed any common patterns or lessons from the solutions that survive the three-month filter? It might be insightful to identify which unscalable hacks tend to evolve into scalable solutions versus those that are better to scrap early on.
