Embracing the 3-Month Rule: A Strategic Approach to Rapid Development

In the world of startups, there’s a common piece of wisdom that many entrepreneurs and developers have encountered: “Do things that don’t scale.” This sage advice, popularized by the esteemed Paul Graham, encourages innovators to prioritize action over perfection. However, when it comes to implementing this strategy in the realm of software development, guidance can be scarce.

After dedicating eight months to building my AI podcast platform, I’ve adopted a pragmatic framework that I like to call the “3-Month Rule.” Essentially, any solution that defies scalability is permitted to exist for a maximum of three months. By this timeline, it must either demonstrate its worth and be developed further, or it will be discarded.

As engineers, we are often conditioned to create thoroughly scalable solutions right from the outset, employing the latest design patterns, microservices, and distributed systems designed to accommodate millions of users. However, such an approach can often lead to indecision and wasted resources in a startup environment. The 3-Month Rule encourages me to embrace a more straightforward, expedient coding style that delivers tangible results and genuine user insights.

Current Infrastructure Strategies: Unconventional Yet Effective

1. Single Virtual Machine Setup

Currently, my entire infrastructure operates on a single virtual machine for a modest fee of $40/month. This VM, while lacking redundancy and relying on manual backups, has delivered invaluable insights about my resource needs. In just two months, I’ve gathered data that far surpasses what any initial capacity planning documents would have provided. Although it has crashed a couple of times – offering a real-world glimpse into unexpected vulnerabilities – I now have a clearer understanding of the operational demands of my platform.

2. Hardcoded Configurations

Instead of utilizing configuration files or environment variables, I’ve adopted a strategy of hardcoded constants throughout my codebase. This approach allows for swift searching through my entire project for any given configuration value, ensuring that any changes I implement are easily tracked and documented. The effort saved here is significant; deploying a minor adjustment takes less time than drafting a dedicated configuration service, which would consume much more development time for minimal benefit.

3. SQLite in Production

Surprisingly, I’ve chosen SQLite to power my production database, which is currently only 47MB in size. This configuration has proven effective for handling multiple concurrent users without performance issues. From this experience, I’ve learned that my database usage trends are
