Embracing the 3-Month Rule: A Pragmatic Approach to Unscalable Innovations
In the world of startup development, the maxim from Paul Graham—”Do things that don’t scale”—is well-recognized, yet its practical execution remains a topic often left undiscussed among engineers, particularly in the realm of coding. After dedicating eight months to the creation of my AI podcast platform, I’ve established a straightforward framework: every temporary hack that isn’t built for scalability has a lifespan of three months. In this period, it either demonstrates its value and is fully developed, or it is phased out.
When we become engineers, the common training places emphasis on crafting solutions that can handle large-scale demands from the outset—think design patterns, microservices, and distributed systems. However, this methodology is primarily the domain of larger companies. In the vibrant world of startups, focusing on scalable solutions can easily become an expensive form of procrastination, as we find ourselves developing for users who do not yet exist and tackling issues that may never arise. This three-month rule helps me prioritize creating straightforward, even “imperfect” code that promptly brings my ideas to life while simultaneously providing crucial insights into actual user needs.
Ingenious Yet Simplistic Infrastructure Hacks
1. Consolidating Resources on One Virtual Machine
Currently, my entire system—comprising the database, web server, background processes, and Redis—operates on a single $40/month virtual machine. While this approach lacks redundancy and involves conducting manual backups, it’s immensely educational. In just two months, I’ve gained more insight into my actual resource requirements than any predictive document could have provided. My platform, which I expected to be resource-heavy, experiences peak usage of only 4GB of RAM. The complex Kubernetes architecture I contemplated would have resulted in managing unused containers instead of solving real problems.
2. Utilizing Hardcoded Configuration
I maintain a straightforward approach to configuration, utilizing hardcoded values for things like pricing tiers and user limits. This technique allows me to quickly index my codebase and track changes through version control. Over three months, I’ve only altered these values three times—making a week of work into a mere 15 minutes of redeployment.
3. Opting for SQLite in Production
Running SQLite for a multi-user application may raise eyebrows, but my database size is a manageable 47MB, efficiently serving 50 concurrent users without issue. This experience revealed to me

This post beautifully encapsulates the pragmatic mindset that many founders and developers need to embrace—prioritizing speed, learning, and adaptability over premature perfection and scalability. The 3-month rule acts as a disciplined yet flexible framework, enabling teams to iterate rapidly, validate assumptions, and prevent over-investment in unproven solutions.
Your approach to infrastructure—starting small with a single VM, hardcoded configs, and SQLite—aligns well with the “build fast, learn fast” philosophy. It reminds me of the “Minimum Viable Infrastructure” concept, where simplicity accelerates feedback loops and reduces technical debt early on.
One insight I’d add is that this methodology also fosters a mindset of continuous evaluation. After three months, whether you scale up or pivot, you’ve gained concrete insights into your users’ behavior and system bottlenecks, which informs smarter decisions later.
Overall, this article underscores that in the startup phase, prioritizing tangible progress and learning over theoretical robustness often leads to better long-term outcomes. Thanks for sharing such an insightful framework!
