Embracing the 3-Month Rule: A Framework for Non-Scalable Solutions in Software Development
In the realm of software development, we often hear the sage advice from Paul Graham: “Do things that don’t scale.” However, the challenge lies in effectively applying this principle, especially in coding practices. After dedicating eight months to developing my AI podcast platform, I’ve implemented a straightforward strategy: any non-scalable solution is given a lifespan of three months. After this period, it must either demonstrate its value and evolve into a robust feature or be discarded.
Rethinking Scalability
As engineers, we are ingrained with the mantra of creating scalable solutions from the outset. We idolize architectures that can handle millions of users, utilizing design patterns, microservices, and distributed systems. Yet, this perspective often stems from the mindset of larger enterprises. In the startup world, pursuing scalable code can sometimes result in costly delays. We can find ourselves optimizing for future users who may never materialize, all while neglecting immediate needs. My three-month rule compels me to craft straightforward code that may lack elegance but is effective and insightful, allowing me to discern the true requirements of my users.
Current Infrastructure Hacks that Prove Effective
Here are the unembellished strategies I currently employ, each reflecting my commitment to practicality over perfection:
1. Consolidated Infrastructure on a Single VM
By running my database, web server, background jobs, and caching on a single $40/month virtual machine, I embrace simplicity with zero redundancy and manual backups. This approach has empowered me to gauge my actual resource needs more effectively than any complicated capacity plan could. I’ve learned that my AI-driven platform operates efficiently at just 4GB of RAM—what a Kubernetes setup would have managed is now a moot point, as I gather invaluable data during crashes.
2. Hardcoded Configurations Across My Codebase
My code features constants like:
python
PRICE_TIER_1 = 9.99
PRICE_TIER_2 = 19.99
MAX_USERS = 100
AI_MODEL = "gpt-4"
While lacking traditional configuration files means redeployment for changes, this method allows for swift searches and tracking through Git history. In three months, I’ve made only three price adjustments, validating the efficiency of this approach: 15 minutes of redeployment vs. 40 hours invested in a complex configuration service.

Great insights! I appreciate how you emphasize practical, rapid experimentation—it’s a mindset that often gets lost in the pursuit of perfect scalability from day one. Your three-month rule reminds me of the concept of “iterative experimentation” seen in lean startup methodologies: build a simple solution, test it quickly, and iterate based on real user feedback. This approach not only accelerates learning but also prevents wasting resources on premature optimization.
Additionally, your infrastructure hacks highlight an important principle: simplicity often leads to better insights. Running everything on a single VM and hardcoding configs might seem ad-hoc initially, but these strategies afford quick iterations and direct control. Over time, these insights can underpin more scalable solutions as your platform matures.
It might be valuable to consider how this framework could scale as your platform grows—perhaps transitioning from hardcoded configs to environment variables or simple config files, and modularizing infrastructure components—but maintaining the core philosophy of rapid validation before optimization. Thanks for sharing your practical approach; it offers a refreshing perspective for engineers balancing immediate needs with long-term growth.
