Embracing the 3-Month Rule: A Pragmatic Approach to Non-Scalable Solutions
In the world of startups, the adage coined by Paul Graham╬ô├ç├╢”Do things that don’t scale”╬ô├ç├╢is familiar yet often misunderstood, particularly in the realm of software development. How do we embrace this philosophy while still ensuring we’re making meaningful progress? After dedicating the last eight months to developing my AI podcast platform, I’ve implemented a straightforward strategy: any unscalable hack is granted a three-month trial period. Following that duration, it must either demonstrate its value through tangible results or be discarded.
As software engineers, we often lean toward crafting solutions that are designed for scalability from the very beginning. We get drawn into the allure of sophisticated design patterns, microservices architecture, and distributing systems meant to accommodate millions of users. However, this mindset can veer into what I call “big company thinking,” especially in a startup-focused environment.
In smaller ventures, prioritizing scalable solutions early on can feel like an expensive exercise in procrastination. You’re often preparing for a hypothetical user base, addressing challenges that may never arise. The three-month rule compels me to produce straightforward, no-frills code that is actually deployed and essentially informs me of what users genuinely require.
My Current Infrastructure Shortcuts: Smart Moves or Just Cutting Corners?
1. Single VM Deployment
I currently host everythingΓÇöa database, web server, background jobs, and cachingΓÇöon a singular $40/month virtual machine. While this might sound risky, it has provided invaluable insights into my real resource needs. Within just two months, IΓÇÖve discovered that my AI-driven platform only requires around 4GB of RAM during peak times. The complex Kubernetes setup I nearly implemented would have left me managing unused resources. Each time the system crashes, I gain genuine feedback about what truly failsΓÇöinformation that often surprises me.
2. Hardcoded Values Across the Codebase
Instead of using configuration files or environment variables, I╬ô├ç├ûve hardcoded critical values like pricing tiers and user limits directly into the code. While this may seem primitive, it allows for quick searches within the codebase. Any price adjustments are easily tracked through Git history, and each update involves merely a short redeployment. Creating a dedicated configuration service would have taken a significant block of time╬ô├ç├╢time I’ve instead invested in learning from agile iterations.
3. Utilizing SQLite in Production

Thank you for sharing this pragmatic approach╬ô├ç├╢it’s a refreshing reminder that sometimes, simple, unscalable solutions implemented quickly can offer invaluable insights early on. The 3-month trial rule provides a disciplined framework to evaluate what truly adds value versus what╬ô├ç├ûs just ╬ô├ç┬úfuture-proofing╬ô├ç┬Ñ with unnecessary complexity.
Your point about deploying everything on a single VM resonates strongly; itΓÇÖs often in the tight feedback loops enabled by such setups that founders and developers learn what the system genuinely needs. Similarly, hardcoding values, while seemingly crude, can accelerate iteration and experimentationΓÇöespecially when clarity and rapid changes are priorities.
Using SQLite in a multi-user environment is an audacious move, but it aligns perfectly with the philosophy of focusing on validated needs over premature optimization. These approaches underscore a core lesson: in early-stage projects, validating real user needs and maintaining agility trump theoretical scalability.
Ultimately, my takeaway is that scalability should be a concern only when it becomes a real bottleneck, not just a hypothetical scenario. Your 3-month rule offers a balanced way to experiment boldly while making informed decisionsΓÇöan approach every startup should consider.
This post highlights a pragmatic and insightful approach to navigating early-stage development challenges. The “3-Month Rule” serves as a disciplined framework that balances the virtues of rapid experimentation with the necessity of data-driven decision-making╬ô├ç├╢a key mindset for startups operating under resource constraints.
Your choice to deploy on a single VM and use hardcoded values exemplifies how quick feedback loops can inform whether a feature or infrastructure decision is worthwhile before investing in complex, scalable architectures. This aligns with the lean startup principle of “build-measure-learn,” emphasizing that real-world usage often reveals needs and bottlenecks that hypothetically designed systems might overlook.
While such shortcuts might seem “primitive,” they are often the most effective way to validate assumptions swiftly. Over time, as the platform matures and user demand grows, transitioning to more scalable solutions will be necessary. The key is to ensure these quick hacks are temporary, guided by clear metrics and the three-month evaluation window.
It’s fascinating how you’ve embraced these pragmatic compromises to prioritize learning and adaptability╬ô├ç├╢core to startup agility. One point worth considering is establishing a clear process for evolving these early solutions into more scalable systems, ensuring that debt doesn’t accumulate but rather informs deliberate upgrades. This disciplined approach can help sustain innovation while gradually building a robust infrastructure.
