Embracing the 3-Month Rule: A Pragmatic Approach to Non-Scalable Solutions in Development
In the world of software development, particularly for startups, the phrase ΓÇ£do things that donΓÇÖt scaleΓÇ¥ often originates from the wisdom of Paul Graham. However, translating this advice into practical applicationΓÇöespecially on the technical sideΓÇöcan be quite challenging. Drawing from my experience in developing an AI podcast platform over the past eight months, I have devised a straightforward framework: every non-scalable approach gets a trial period of three months. If it proves its worth by then, it gets a proper implementation; if not, itΓÇÖs time to move on.
As engineers, we tend to prioritize scalable solutions right from the beginningΓÇöcreating robust design patterns and leveraging microservices. However, in a startup environment, focusing solely on scalability can lead to delays and inefficiencies, leading us to optimize for hypothetical future users instead of current needs. My 3-month rule encourages me to produce straightforward, albeit imperfect, code that can be released quickly. This allows me to gather real user feedback and understand their requirements more effectively.
Insights from My Current Infrastructure Hacks
1. Centralized Operations on a Single VM
I run my entire infrastructure╬ô├ç├╢including the database, web server, and background jobs╬ô├ç├╢on a single $40 per month virtual machine without any redundancy. Although this may sound reckless, the insight gained has been invaluable. I’ve learned about my actual resource requirements more in two months than any capacity planning document could provide. For instance, my platform’s peak usage demands only 4GB of RAM, which means that the complex Kubernetes setup I nearly built would have been unnecessary. Each crash (I’ve had a few) offers real data on system weaknesses that defy my initial expectations.
2. Configuration Hardcoding
Instead of relying on external configuration files or environment variables, I have embedded constants throughout my code. Although this means that changes require a redeployment, the advantages are surprising. It allows for swift searches across the codebase for any configuration value. Each change has been documented in my version control history, fostering a clear audit trail. Investing in a dedicated configuration service would have taken a week, but in three months, I’ve needed to make only three changes╬ô├ç├╢resulting in just 15 minutes of redeployment.
3. Utilizing SQLite for Production
Running a multi-user application with SQLite may raise eyebrows, but my relatively small database has proven to be effective. With only 47MB

This framework strikes a compelling balance between agility and practicality, especially for startups where time-to-market and validated learnings are critical. The 3-month trial period provides a clear, structured way to assess whether a non-scalable solution genuinely addresses current needs before investing resources in more complex, scalable infrastructure.
Your hands-on experience with centralized operations and hardcoded configurations underscores the value of real-world data over theoretical planning╬ô├ç├╢reminding us that sometimes simple, quick setups can yield faster insights than elaborate systems prematurely built on assumptions. Running SQLite in production for a smaller workload is a great example of pragmatism, emphasizing that “scalable” doesn╬ô├ç├ût always mean “necessary from day one.”
Overall, your approach encourages a disciplined iteration process, allowing teams to avoid over-engineering while maintaining focus on immediate value. It might also be beneficial to document lessons learned from these quick experiments, creating a knowledge base that guides future decisionsΓÇöespecially as the platform scales beyond the initial 3-month window. Looking forward to seeing how this framework evolves as your project grows!
This post highlights a pragmatic approach that many technical founders and engineers can resonate withΓÇöparticularly the emphasis on rapid experimentation driven by real-world feedback rather than upfront scalability concerns. The 3-month rule acts as a disciplined checkpoint, preventing analysis paralysis and ensuring resources are allocated toward solutions that genuinely add value at the current stage.
Your example of running everything on a single VM aligns with the concept of “modus operandi” over “modus operandi architecture,” where understanding practical limits through real data often surpasses theoretical planning. Similarly, hardcoding configurations for quick iteration can be counterintuitive in traditional environments but can significantly accelerate testing and learning cycles early on. It╬ô├ç├ûs a reminder that sometimes simplicity, backed by immediate feedback, outweighs premature optimization.
The use of SQLite in production for a small dataset exemplifies the importance of context-aware decisions╬ô├ç├╢what╬ô├ç├ûs “wrong” in theory may be perfectly valid practically, especially when the primary goal is to validate assumptions swiftly.
Overall, your framework mirrors principles from lean startup methodologies╬ô├ç├╢focusing on “build-measure-learn” loops╬ô├ç├╢and underscores that temporary, imperfect solutions are powerful tools for navigating initial traction phases. As your platform scales, you can then decide when to invest in more robust infrastructure, guided by validated needs rather than assumptions. Thanks for sharing this nuanced perspective!
