Embracing the 3-Month Rule: A Pragmatic Approach to Unscalable Solutions in Tech Development
In the realm of startup culture, one piece of wisdom frequently cited is Paul Graham’s mantra: “Do things that don’t scale.” Yet, while this advice is widely acknowledged, the practical implementation of it in the world of coding often goes unexplored.
Over the past eight months, as I’ve been developing my AI-focused podcast platform, I’ve formulated a straightforward yet powerful framework: each unscalable solution I implement is given a lifespan of precisely three months. After this period, it’s either validated and evolved into a robust feature, or it’s phased out entirely.
Rethinking Scalability in Startups
As engineers, we’re conditioned to prioritize scalable solutions from the outset—think design patterns, microservices, and distributed systems. While these approaches are indeed effective for larger enterprises handling millions of users, they often become a hindrance in a startup environment.
In a startup setting, investing time in scalable architecture early on can result in costly delays. By focusing on potential users who may or may not materialize, we risk wasting resources addressing problems that aren’t relevant yet. My three-month rule encourages me to produce straightforward, even rudimentary code that can be deployed quickly, allowing me to learn firsthand what my users actually need.
Current Hacks in My Infrastructure
Here’s a snapshot of my current infrastructural quirks and the pragmatic reasoning behind them:
1. Consolidated Operations on a Single VM
With my database, web server, background jobs, and caching all running on a single $40/month virtual machine, I consciously forego redundancy and perform manual backups to my local environment. This may seem reckless, but it’s provided invaluable insights into my actual usage patterns. After monitoring resource allocation for two months, I’ve discerned that my platform’s peak usage is just 4GB of RAM. The complex Kubernetes setup that I almost implemented would have been managing empty resources instead of functional workloads. When crashes occur—which they have, twice—I gain real-time understanding of the root causes, which tend to differ from my initial expectations.
2. Directly Hardcoded Configuration
I maintain hardcoded configurations throughout my codebase:
PRICE_TIER_1 = 9.99
PRICE_TIER_2 = 19.99
MAX_USERS = 100
AI_MODEL = "gpt-4"
With no reliance on config files or environment

Thank you for sharing this insightful approach—it’s a refreshing reminder that agility often trumps initial scalability in early-stage development. The three-month rule provides a tangible framework to balance experimentation with eventual validation, which is especially critical when resources are limited.
Your emphasis on rapidly deploying rudimentary solutions to gather real-world data aligns well with lean startup principles, allowing for iterative learning. I particularly appreciate the pragmatic infrastructure choices, such as consolidating services on a single VM and hardcoding configurations for speed—these decisions underscore the importance of understanding core user needs before scaling complexity.
One aspect to consider for future iterations might be the integration of lightweight monitoring tools during these three months. This could help quantify the insights gained from manual processes and validate whether the quick-and-dirty solutions are truly meeting user demands. Overall, your methodology champions an experimental mindset that can dramatically reduce waste and accelerate learning—a crucial advantage in the fast-paced startup landscape.
