Embracing the Unscalable: The 3-Month Rule for startup Development
In the world of startups, the common wisdom from Paul Graham rings true: “Do things that don’t scale.” However, the challenge lies in effectively applying this advice within the realm of software development. After dedicating the past eight months to building my AI podcast platform, I’ve come up with a unique approach—one that allows me to make meaningful progress while simultaneously learning from my efforts: the 3-Month Rule.
The Concept Behind the 3-Month Rule
As engineers, we often feel pressured to design “scalable” solutions from the outset. We’re trained to think in terms of elaborate architectures—think microservices, distributed systems, and design patterns meant to support millions of users. This approach may suit large companies, but in the startup arena, such solutions can be a costly form of procrastination. Instead of anticipating the needs of non-existent users, I advocate for a lean approach: any unscalable solution gets a trial period of three months. At the end of this timeframe, if the hack hasn’t proven its worth, it gets scrapped.
By forcing myself to write straightforward, often imperfect code, I can launch features that gather real user feedback, revealing their needs and preferences much more effectively than theoretical planning ever could.
My Key Strategies and Their Learnings
1. Consolidation on a Single VM
Currently, everything from the database to the web server is hosted on one virtual machine, costing just $40 a month. This setup comes with the risk of zero redundancy and manual backups, yet has delivered invaluable insights into my resource requirements. Over the last two months, I’ve learned that my “AI-heavy” platform peaks at only 4GB of RAM, contradicting my initial fears that it would require much more complex infrastructure like Kubernetes.
Frequent crashes provide pertinent data about system vulnerabilities, illuminating areas I never anticipated before.
2. Hardcoded Configurations
By embedding configuration values directly into my code (such as pricing tiers and user limits), I’ve eliminated the need for external configuration files or environment variables. This approach may seem unorthodox, but it allows me to quickly track changes through version control, ensuring all adjustments are easily retrievable and historically documented. While creating a dedicated configuration management service might have taken substantial time upfront, the actual value of these adjustments has proven negligible over the last three months.
