Embracing the 3-Month Rule: A Pragmatic Approach to Developing Unscalable Solutions

In the ever-evolving landscape of software development, the conventional wisdom of “do things that don’t scale” is often bandied about, particularly by thought leaders like Paul Graham. However, the practical execution of this philosophy, particularly within the realm of coding, is rarely discussed.

Having dedicated the last eight months to creating my AI podcast platform, I have devised a pragmatic framework: every unscalable approach I implement is given a three-month trial period. At the conclusion of this period, each hack must either validate its worth and undergo proper development or be discarded.

Why Think Small?

As engineers, we’re often trained to prioritize scalability from the outset—embracing architectural paradigms such as microservices or distributed systems designed to accommodate millions of users. Yet, in the startup environment, this mindset can become a costly form of procrastination; we optimize for hypothetical future users and tackle problems that may never arise. My three-month rule compels me to prioritize simplicity, allowing me to write straightforward code that can be deployed quickly, thus revealing genuine user needs.

Current Infrastructure Hacks: Intelligent Choices for Growth

1. Consolidated Virtual Machine

Everything for my application—database, web server, background jobs, and caching—is hosted on a single $40/month virtual machine. While this setup offers no built-in redundancy and requires manual backups, the insights gained have proven invaluable. In just two months, I discovered my resource consumption peaks at a mere 4GB of RAM. The complex Kubernetes configuration I thought I needed? It would have merely managed empty containers. Each time the system crashes—twice so far—I gather critical information about real-world issues, often surprising me.

2. Hardcoded Configuration

Configuration values are hardcoded directly into the application, without the use of files or environment variables. This may seem backward, but it allows for rapid tracking and easy changes, with each adjustment captured in version history. Rather than investing a week to develop a sophisticated configuration service, I’ve made changes three times in three months, taking only 15 minutes for redeployment—an investment of time far less than the alternative.

3. SQLite for Production Use

Currently, my application runs on SQLite, which effectively powers a multi-user environment with a database size of only 47MB. Surprisingly, it manages 50 users simultaneously with ease. This experiment has taught me

  • This post offers a compelling perspective on how embracing simplicity and rapid iteration—especially through the 3-month rule—can lead to meaningful insights and more targeted development. I appreciate how you’ve pragmatically challenged conventional scalability assumptions, especially in a startup context where speed and learning often outweigh immediate robustness.

    The tangible benefits you’ve highlighted—such as using a single VM and hardcoded configs—demonstrate that real-world constraints often reveal the actual bottlenecks and needs much faster than theoretical planning. Your approach aligns with the idea that “doing things that don’t scale” can be a powerful way to gather evidence before investing heavily in infrastructure—saving time and resources while maintaining agility.

    One takeaway I’d add is that this methodology not only accelerates learning but also fosters a mindset of continuous validation, which is crucial for startups. It might be interesting to consider how this 3-month rule could evolve over time—perhaps as the product matures, you could systematically transition unscalable hacks into more scalable solutions once validated.

    Thanks for sharing such a practical and insightful framework—definitely a valuable read for engineers balancing rapid iteration with strategic growth!
