Embracing Imperfection: The 3-Month Rule in Building a Scalable Future
In the entrepreneurial world, advice such as “Do things that don’t scale,” often attributed to Paul Graham, is common wisdom. Yet, the practical implementation of this principle, particularly in the realm of software development, isn’t frequently discussed. Over the past eight months of developing my AI podcast platform, I’ve crafted a straightforward yet effective framework that I like to call the “3-Month Rule.” This guideline entrusts each unscalable hack with a three-month lifespan, after which it either earns a permanent place in our tech stack or gets phased out.
As engineers, our instincts drive us to conceive scalable solutions right from the start. We often find ourselves engrossed in design patterns, microservices, and complex architectures tailored for potential millions of users. However, this mindset can lead to unnecessary complexity, particularly in a startup environment where focusing on scalability can prove to be a form of procrastination.
My three-month rule encourages a departure from this pattern, compelling me to write straightforward, albeit “suboptimal,” code. This approach has provided real-world insights into user needs and platform performance—lessons that can’t be gleaned from theoretical designs alone.
Current Infrastructure Strategies: Innovating Through Simplicity
1. Consolidated Resources on a Single VM
Currently, every component of my application—from the web server to the database and background jobs—operates on a single $40/month virtual machine. This setup lacks redundancy and relies on manual backups.
Why is this a smart decision? In just two months, I’ve learned more about my application’s resource requirements than any capacity planning documentation would have revealed. My “AI-heavy” platform consistently peaks at only 4GB of RAM, proving that a complex Kubernetes setup would have been overkill, given that I’d have been managing underutilized resources. Each time a failure occurs—twice so far—I gain valuable insights into the specific causes, which often defy my initial expectations.
2. Hardcoded Configuration Values
Rather than using configuration files or environment variables, I have opted for hardcoded constants throughout my codebase, such as:
plaintext
PRICE_TIER_1 = 9.99
PRICE_TIER_2 = 19.99
MAX_USERS = 100
AI_MODEL = "gpt-4"
This may seem outdated, but it has a hidden advantage: I can instant

This is a fantastic perspective on the practical realities of startups and early-stage product development. The 3-Month Rule effectively balances the need for rapid iteration with learning from real-world usage, which often surpasses theoretical planning. I appreciate how you emphasize that initial simplicity—embracing “suboptimal” solutions—can lead to more actionable insights and a clearer understanding of user needs.
Your example of consolidating resources on a single VM underscores the value of starting lean and learning the actual workload before overengineering. Similarly, using hardcoded configuration values may seem unorthodox, but it facilitates quick adjustments during rapid experimentation, which is crucial in the early days.
This approach echoes the broader principle that delivering value early and iterating based on real feedback should take precedence over creating a perfect, scalable architecture from the outset. In my experience, balancing temporary workarounds with a clear exit plan helps safeguard against technical debt while maintaining agility. Looking forward to seeing how your framework evolves as your platform scales!
