Embracing the 3-Month Rule: A Flexible Approach to Unscalable Solutions

In the startup ecosystem, efficiency and adaptability are crucial. A well-known piece of advice from Paul Graham encourages aspiring entrepreneurs to “do things that don’t scale.” However, the practical implementation of this concept within the realm of software development often goes unexplored.

After dedicating eight months to developing my AI podcast platform, I have devised a straightforward framework: every unsustainable hack receives a trial period of three months. Following this timeframe, the hack either proves its effectiveness and transitions into a properly structured solution, or it is abandoned.

Rethinking Scalability in Startups

Engineers are typically trained to create scalable solutions from the outset, employing design patterns, microservices, and distributed systems to craft robust architectures capable of handling millions of users. While this approach may be beneficial for large companies, it can lead to unnecessary complexity in a startup environment. In many cases, prioritizing scalability early on merely delays decision-making and places effort into optimizing for hypothetical users and problems that may never arise.

My 3-month rule compels me to write straightforward, unrefined code that is deployable. This approach not only accelerates the development process but also provides valuable insights into user needs that can only be gleaned through practical application.

Ingenious Yet Simple Hacks

Here are some of my current unconventional infrastructure strategies, demonstrating how they contribute to my learning process:

1. Single Virtual Machine (VM) Operations

All crucial components—database, web server, background jobs, Redis—are hosted on a single $40/month VM. While this setup lacks redundancy, it has provided immediate insights into my resource needs. In just two months, I’ve discovered my platform typically operates within a 4GB RAM threshold. Had I opted for a more complex infrastructure, I would have wasted time managing empty containers before understanding my actual requirements. When the VM has gone down, I’ve gained real-time insights into the failure points, which have often contradicted my assumptions.

2. Hardcoded Settings

Instead of using configuration files or environment variables, I have hardcoded constants distributed throughout my codebase:

PRICE_TIER_1 = 9.99
PRICE_TIER_2 = 19.99
MAX_USERS = 100
AI_MODEL = "gpt-4"

Changing a parameter necessitates a redeployment, but this simplicity allows me to quickly locate any value I wish to
