Embracing the 3-Month Rule: A Strategic Approach to Unscalable Solutions
In the world of startups and software development, Paul Graham’s adage, “Do things that don’t scale,” is often quoted but rarely operationalized within coding practices. After spending eight months developing my AI podcast platform, I have formulated a straightforward strategy: every unscalable hack I implement is given a lifespan of three months. At the end of this period, each solution must either demonstrate its worth and evolve into a more robust system, or it will be discarded.
Engineers are typically conditioned to prioritize “scalable” solutions from the outset. We are taught to utilize design patterns, microservices, and distributed systems, creating architectures capable of accommodating millions of users. While this is certainly a valuable mindset for larger organizations, it can lead startups to invest in complex solutions prematurely. More often than not, pursuing scalability at the beginning translates to expensive delays, as we prepare for potential users who may never materialize. My three-month rule compels me to write direct, straightforward code that allows me to learn what my users genuinely require.
Current Infrastructure Hacks: A Smart Approach to Learning
1. All-in-One Virtual Machine Setup
I run my database, web server, background tasks, and Redis on a single virtual machine costing $40 a month. This setup lacks redundancy and depends on manual backups to my local system.
Why is this advantageous? The experience has revealed my actual resource needs far more accurately than any theoretical capacity planning could have. I learned that my “AI-heavy” platform typically peaks at just 4GB of RAM. The complex Kubernetes framework I almost implemented would have only involved managing idle containers.
When my system crashes—something that has occurred twice—I gain concrete insights into the specific failures. Interestingly, the causes have consistently been unexpected.
2. Simplified Hardcoded Configuration
My approach to configuration is straightforward:
plaintext
PRICE_TIER_1 = 9.99
PRICE_TIER_2 = 19.99
MAX_USERS = 100
AI_MODEL = "gpt-4"
With no config files or environmental variables, these hardcoded constants mean that any updates necessitate redeployment.
The advantage? I can quickly search my entire codebase for configuration values. Each price modification can be traced through git history, ensuring that every change receives code review—even if it’s just by myself.
While constructing a dedicated configuration service would take a

Great insights into balancing rapid iteration with intentionality in early-stage development! The 3-month rule offers a pragmatic framework—allowing you to quickly test ideas while setting a clear horizon for refactoring or pivoting. I especially appreciate how you emphasize learning from real-world failures, such as system crashes, rather than relying solely on theoretical capacity planning.
Your approach to infrastructure—using a simple VM and hardcoded configs—mirrors the “build simple first” philosophy, which can save substantial time and resources upfront. It reminds me of the concept of “practical tech debt”: intentionally accepting short-term constraints to gain clarity and flexibility. As your platform matures, transitioning toward more scalable solutions can be done gradually, informed by your actual usage data.
One thought: as your startup scales, consider implementing lightweight monitoring or feature flags to keep the feedback loop tight without introducing unnecessary complexity. This way, you can retain the agility of your current approach while preparing for growth. Looking forward to seeing how your framework evolves!
