Embracing the 3-Month Rule: A Pragmatic Approach to Software Development
When it comes to startup culture, the mantra “Do things that don’t scale,” popularized by Paul Graham, is a common point of discussion. However, I have found that the challenge lies not just in understanding this philosophy but effectively incorporating it into a technical framework. Over the past eight months of developing my AI podcast platform, I’ve devised a strategy that I call the “3-Month Rule.” Simply put, any non-scalable hack gets a three-month trial period. At the end of this timeframe, it must either prove its worth and be fully implemented, or be discarded.
As engineers, we are often conditioned to prioritize scalable solutions from the get-go. This typically translates to employing design patterns, microservices, and distributed systems capable of handling millions of users. However, such thinking may not serve a startup well. In fact, scalable code can often mean expensive procrastination—optimizing for potential users who may never exist and resolving issues that may never arise. The 3-Month Rule encourages me to focus on creating straightforward, though perhaps less-than-ideal, code that can be deployed quickly and expose real user needs.
Current Infrastructure Strategies: Smart Hacks That Work
Here are some of the unconventional yet effective strategies I’ve adopted in my project:
1. Consolidated Environment on a Single Virtual Machine
Currently, my database, web server, background jobs, and caching are all running on one $40/month VM. Although it lacks redundancy and relies on manual backups to my local machine, this approach has been enlightening. Within two months, I’ve gained more insight into my actual resource needs than any capacity planning document could offer. For instance, I discovered that my platform’s peak usage is only 4GB of RAM. The complex Kubernetes setup I almost deployed would have required managing virtually empty containers.
When my system crashes—twice, to date—I’m able to gather immediate, valuable data on the causes. Surprisingly, the failures have always differed from my predictions.
2. Hardcoded Configuration for Simplicity
Instead of relying on configuration files or environment variables, I’ve hardcoded key parameters directly into the code. My constants look something like this:
python
PRICE_TIER_1 = 9.99
PRICE_TIER_2 = 19.99
MAX_USERS = 100
AI_MODEL = "gpt-4"
The beauty of this
One Comment
Thank you for sharing such a practical and insightful approach with the 3-Month Rule. I appreciate how it emphasizes the importance of rapid experimentation and learning early on—something that’s often overlooked in pursuit of scalability from the start. Your strategy encourages a mindset of validation rather than perfection, allowing startups to prioritize real user feedback over speculative optimization.
The examples you provided, like consolidating resources on a single VM and hardcoding configurations, highlight how initial simplicity can reveal actual needs more effectively than overly complex setups. It reminds me of the “fail fast” philosophy, where early failures provide valuable lessons that shape scalable, more refined solutions later.
One aspect I’d love to see explored further is how you plan to evolve these initial hacks once the 3-month trial period ends. Do you have a framework for transitioning from quick, non-scalable solutions to more robust architectures? Balancing between agility and future scalability is often challenging, and your approach might serve as a blueprint for others striving to navigate that transition smoothly.
