Embracing Imperfection: The 3-Month Rule for startup Development

In the world of startups, the age-old wisdom of Paul Graham rings true: “Do things that don’t scale.” Yet, the challenge lies in effectively applying this principle, especially in the realm of coding. Over the past eight months while working on my AI podcast platform, I’ve developed a straightforward approach: every unscalable hack is given a lifespan of just three months. After this trial period, it either proves its merit and gets refined into a robust solution, or it’s eliminated from the project altogether.

The startup Mindset: Rethinking Scalability

As engineers, we are often conditioned to prioritize scalable solutions from the outset. We dive into design patterns, microservices, and sophisticated architectures meant to handle vast numbers of users. However, this “big company” mentality can be a hindrance for startups, where premature optimization often serves as an expensive form of procrastination. Instead of preparing for problems that may never arise, my 3-month rule empowers me to write straightforward, though less elegant, code that can be deployed quickly and yield valuable insights about user needs.

My Strategic Infrastructure Hacks

Here are a few of my current approaches that may seem unconventional, but are surprisingly effective based on my circumstances:

1. Consolidated Resources on a Single VM

All components of my platform—database, web server, background jobs, and caching—operate on a single $40/month virtual machine. While this setup lacks redundancy and requires manual backups, it has allowed me to gain profound insights into my resource needs within just two months. For example, I’ve discovered that my AI-centric platform peaks at 4GB of RAM—far less than I anticipated. This approach has provided real data during crashes, illuminating unexpected vulnerabilities in the system.

2. Hardcoded Configurations

My codebase relies on explicit constants for configurations instead of using configuration files or environment variables. This method allows me to quickly search and track changes across the entire codebase. While I could have invested time in building a configuration service, the reality is that I’ve only modified these values three times in three months, proving this approach to be time-efficient.

3. Utilizing SQLite in Production

I’m currently employing SQLite to power a multi-user web application that handles a mere 47MB database size. Surprisingly, it supports 50 concurrent users seamlessly. This experience has revealed that my access patterns are primarily read-heavy, making SQLite
