Embracing the 3-Month Rule: A Pragmatic Approach to Non-Scalable Coding
In the world of startup development, the well-known mantra from Paul Graham╬ô├ç├╢”Do things that don’t scale”╬ô├ç├╢often meets some resistance. The challenge lies not just in adopting this philosophy, but in translating it into actionable practices within the realm of coding.
After eight months of developing my AI podcast platform, IΓÇÖve formulated a straightforward framework: each non-scalable solution I implement is given a lifespan of just three months. At the end of that period, I assess its value; it either warrants a refined version or is discarded.
Here╬ô├ç├ûs a reality check: as engineers, we╬ô├ç├ûre often conditioned to prioritize scalable architecture right from the outset╬ô├ç├╢design patterns, microservices, distributed systems. While this intricate design is vital for established companies, at a startup, focusing on scalability too early may simply lead to delayed decisions and unnecessary complexity. Instead, my three-month guideline compels me to prioritize simplicity. I focus on writing code that is functional and delivers real insights about my users’ needs.
Current Infrastructure Strategies That Surprisingly Work:
1. All-in-One Server Approach
Everything from the database to the web server resides on a single $40/month virtual machine. This choice eliminates redundancy, and I handle backups manually.
Why is this a smart move? In the past two months, IΓÇÖve gained invaluable insight into my resource requirements that no theoretical planning document could have provided. My ΓÇ£AI-dependentΓÇ¥ platform only peaks at 4GB of RAM, which suggests the extensive Kubernetes setup I had considered would have had empty containers to monitor. Whenever the system goes downΓÇöwhich has happened twiceΓÇöI receive actual data on what fails; itΓÇÖs rarely what I initially anticipated.
2. Hardcoded Values for Configuration
Rather than using config files or environment variables, IΓÇÖve opted for hardcoded constants throughout my codebase. Modifying any settings necessitates redeploying.
The unexpected advantage here is efficiency. I can rapidly search my codebase for any specific configuration variable. Each pricing adjustment is logged in git history, and every change undergoes a review process, albeit with just me evaluating my own pull requests. The time expenditure for such adjustments has amounted to only 15 minutes of deployment over three months, as opposed to investing an entire week on a configuration service.
3. SQLite as a Production Database
IΓÇÖm utilizing SQLite for what is essentially a multi-user web application. My

This post presents a compelling case for embracing rapid experimentation and iterative learning in startup development. The 3-month rule is a practical heuristic that encourages founders and engineers to focus on delivering immediate value without becoming bogged down by premature scaling concerns.
Your approach╬ô├ç├╢starting with a simple, all-in-one infrastructure and hardcoded configurations╬ô├ç├╢aligns well with the “build fast, learn fast” philosophy. It╬ô├ç├ûs especially insightful how you used actual system failures to inform future decisions rather than relying purely on theoretical scalability models.
One thing to consider moving forward is how to transition from these initial non-scalable setups to more scalable architectures as your platform grows. Having a plan for gradual migrationΓÇöperhaps leveraging the insights gained during these early stagesΓÇöcould ensure you maintain agility while preparing for increased demand.
Thanks for sharing these pragmatic strategies; they serve as a valuable reminder that early-stage development benefits greatly from simplicity and rapid iteration.
This framework offers a pragmatic perspective that resonates strongly with the lean startup philosophy. Emphasizing rapid experimentation within a constrained timeframe╬ô├ç├╢like your three-month rule╬ô├ç├╢allows founders and developers to focus on validated learning rather than premature optimization. Your approach to infrastructure, such as using a single VM and hardcoded configurations, aligns with the principle of “getting to first use” quickly and learning from real user interactions before scaling complexities.
Additionally, choosing SQLite for initial development is a classic example of prioritizing simplicity and speed over scalability, which often proves more insightful early on. As you gather data and understand user patterns, it becomes easier to transition to more scalable solutions when truly necessary. Overall, your approach underscores that building a minimal, functional MVP with room for iterative improvement is often more effective than over-engineering from the outsetΓÇöespecially in the unpredictable startup environment.
This is a compelling perspective on balancing practical experimentation with scalable architecture, especially in the early stages of a startup. Your “3-month rule” approach effectively emphasizes the importance of quick iteration and learning over premature optimization. I appreciate how adopting simple, disposable solutions—like a single VM, hardcoded configs, and SQLite—allows for rapid feedback and resource understanding. It’s a reminder that foundational insights often come from working with what’s simplest, rather than over-engineering from the start. As your data and user base grow, it will be easier to transition to more scalable and flexible systems. Thanks for sharing this pragmatic framework—it’s a valuable addition to the ongoing conversation about shipping quick, learning fast, and adjusting thoughtfully.
