Title: Embracing the 3-Month Rule: A Pragmatic Approach to Building Scalable Solutions in Startups
When it comes to startup development, the advice from Paul Graham to “do things that don’t scale” is often quoted, but the practical implementation of this philosophy in coding remains less discussed. Having spent the last eight months crafting my AI podcast platform, I’ve devised a straightforward framework that encourages experimentation: I give every unscalable workaround a lifespan of three months. After this period, the solution must either prove its worth and evolve into a robust build or be abandoned.
As developers, we often feel the pressure to create scalable solutions from the outset, embracing complex design patterns and architecting systems capable of handling vast numbers of users. However, this mindset can lead to inefficient procrastination, particularly in the early stages of a startup. The three-month rule compels me to focus on delivering simple, functional code, allowing me to gain insight into user needs and preferences.
Here’s a Look at My Current Infrastructure Strategies and the Reasons Behind Their Effectiveness:
1. Consolidation on a Single Virtual Machine
My platform operates entirely on a single $40/month VM, hosting everything from the database to the web server and background jobs. While this setup lacks redundancy and requires manual backups, it has provided invaluable insights into my resource requirements far beyond what any capacity planning document could offer. I’ve learned that my “AI-heavy” platform only peaks at 4GB RAM and dodged the time-consuming setup of a Kubernetes environment, which would have overloaded me with unnecessary management tasks.
2. Simplicity with Hardcoded Configurations
I have opted for straightforward hardcoding of configuration values directly in the code, rather than utilizing configuration files or environment variables. While this method may not align with best practices, it has allowed me to quickly access and modify values without the overhead of a dedicated configuration service. Every secondary change I’ve needed has required just a quick redeployment, saving countless engineering hours.
3. Efficient Use of SQLite in Production
While unconventional, I have chosen SQLite as the database for my multi-user application. With a compact 47MB size, it efficiently supports up to 50 concurrent users. This decision has spotlighted my access patterns, revealing a predominantly read-heavy usage which is perfectly suited for SQLite—thus averting unnecessary optimization concerns that would arise from a more complex database setup like Postgres.
4. Streamlined Deployment Process

Thank you for sharing your candid insights and practical approach to early-stage development. The 3-month rule is a powerful way to foster agility and avoid paralysis by over-engineering—especially in the startup environment where time and resources are limited. I appreciate the emphasis on rapid experimentation; it really aligns with the lean startup philosophy of validated learning.
Your choice to consolidate everything on a single VM and use SQLite for initial deployment exemplifies how focusing on core functionality and understanding actual usage patterns allows for smarter iteration. Hardcoded configurations, while not ideal long-term, serve as an effective placeholder during initial phases to speed up changes and gather real user data.
One thing I’d add is the importance of setting clear exit criteria at the end of that three-month period—whether it’s scaling up, refining configurations, or pivoting to more robust solutions. This disciplined approach ensures that temporary hacks evolve into sustainable architectures as your user base grows.
Overall, your framework encourages a healthy balance between pragmatism and strategic planning, which is crucial for startups navigating the uncertain early stages. Looking forward to seeing how your platform evolves!
