Embracing the 3-Month Rule: A Practical Approach to Non-Scalable Coding for Startups
In the ever-evolving landscape of startup development, one piece of wisdom often stands out: “Do things that don’t scale.” Coined by Paul Graham, this advice is well-known, yet there╬ô├ç├ûs a surprising lack of discussion around how to effectively apply it within the realm of coding.
During my eight months of developing an AI podcast platform, IΓÇÖve stumbled upon a straightforward framework that I now swear by: each unscalable hack is given a lifespan of just three months. After this period, it must either demonstrate its worth and be properly implemented, or it will be removed from the project.
ItΓÇÖs a common trend among engineers to prioritize scalable solutions right from inception. We are often tempted by the allure of sleek design patterns, microservices, and distributed systemsΓÇöall intended to handle millions of users. But this mindset predominantly caters to larger companies and can lead to unnecessary delays in a startup setting. At this stage, focusing on scalability may be a form of costly procrastination, as we are optimizing for hypothetical future users rather than addressing current user needs. With my 3-month rule, I find myself writing straightforward, albeit imperfect code that actually gets deployed, allowing me to understand what users truly require.
My Current Infrastructure Hacks: Smart Decisions in Disguise
1. Consolidated Infrastructure on a Single VM
I operate my database, web server, background jobs, and Redis all on a single $40/month virtual machine, with no redundancy and manual backups to my local machine.
This might seem reckless, but itΓÇÖs been invaluable in helping me truly grasp my resource requirements in just two monthsΓÇöfar better than any capacity planning document would have. IΓÇÖve learned that my ΓÇ£AI-heavyΓÇ¥ platform operates within a peak of 4GB RAM. Had I gone ahead with a complex Kubernetes setup, I would have been managing empty containers instead of refining my core functionality.
When the system has crashed (which has happened twice), IΓÇÖve gained real insights into the actual causes of failureΓÇöinsights that typically defy my initial expectations.
2. Hardcoded Configuration Values
Instead of relying on configuration files or environment variables, IΓÇÖve opted for hardcoded constants throughout my codebase:
“`python
PRICE_TIER_1 = 9.99
PRICE_TIER_2 = 19.99
MAX_USERS = 100
AI_MODEL = “gpt-

This is an insightful and practical approach to early-stage development. The 3-month rule effectively balances the urgency of deploying functional code with the reality that many “perfect” solutions become obsolete or unnecessary as you learn more about your users. I appreciate your emphasis on focusing on current needs rather than hyper-optimizing for scale too early ╬ô├ç├╢ it aligns with the lean startup principles of rapid iteration and validated learning.
Your example of consolidating infrastructure on a single VM is particularly relevant for startups operating with limited resources. It allows for faster experimentation, easier troubleshooting, and a grounded understanding of real workload demands. Similarly, starting with hardcoded configuration values expedites development and reduces complexity, enabling quicker pivots based on user feedback.
One thing to consider as you approach the end of the three months is implementing lightweight abstractions or configuration management tools before expanding to more scalable architectures. This can help maintain agility while preparing for future scaling, without sacrificing the learnings gained from initial hacks.
Overall, your framework encourages a disciplined yet flexible mindset ΓÇö focusing on delivering value first and optimizing for scale only when the need truly arises. Thanks for sharing this thoughtful approach!
This is a compelling approach that underscores an often-overlooked truth: in the early stages of a startup, speed and learning far outweigh the benefits of perfect scalability. Your 3-month rule reminds me of the concept of “release early, release often,” emphasizing rapid iteration to gather real user feedback rather than investing heavily in hypothetical future demands.
The infrastructure hacks you describeΓÇösuch as consolidating everything on a single VM and hardcoding configurationΓÇöare practical shortcuts that allow for fast experimentation and immediate learning. While these may seem risky or unorthodox, they reflect a pragmatic philosophy: validate core assumptions quickly, then iterate toward more scalable solutions as user needs become clearer.
This approach also highlights an important insight: sometimes, the best way to understand scaling is to first understand your actual usage patternsΓÇöan understanding that is often obscured by complex setups. By embracing simplicity and imperfection temporarily, startups can pivot more effectively, avoid overengineering, and focus on creating value.
I’d add that as your user base grows and your understanding deepens, systematically refactoring and adopting scalable infrastructure will become more manageable╬ô├ç├╢it’s an evolutionary process rather than an all-or-nothing switch. Your framework exemplifies how intentional short-term sacrifices in sophistication can lead to better long-term product-market fit.
