Embracing the 3-Month Experimentation Framework for Startup Success
In the entrepreneurial landscape, the adage from Paul Graham, “Do things that don’t scale,” resonates with many. However, the challenge lies in translating this advice into actionable steps, particularly in the realm of software development.
Having spent the last eight months developing my AI podcast platform, I’ve stumbled upon a straightforward yet effective strategy: every unscalable approach I implement is granted a lifespan of just three months. At the end of this period, the solution is either validated and transformed into a robust feature or discarded altogether.
As engineers, we are often conditioned to pursue scalability from the outset. We gravitate toward intricate design patterns, microservices, and distributed systems—all tailored for accommodating vast user bases. But in the startup world, this mindset can lead to costly delays, as we invest time in optimizing for potential users that may never arrive. My three-month rule compels me to adopt a more pragmatic approach, concentrating on swift, functional code that provides invaluable insights into user needs.
Current Infrastructure Hacks: Smart Simplicity in Action
1. All-In-One Virtual Machine Setup
By hosting my database, web server, and background jobs on a single $40/month virtual machine, maintenance is straightforward, albeit with zero redundancy and manual backups to my local system. Here’s the brilliance: I’ve quickly gauged my actual resource requirements—my platform operates smoothly with just 4GB of RAM. Had I opted for a complex Kubernetes setup upfront, I’d likely be managing idle containers.
When the system crashes (which has happened twice), I gather real data about failures—typically not what I anticipated.
2. Hardcoded Configuration Values
I rely on fixed constants scattered throughout my codebase, eliminating configuration files and environment variables for the sake of simplicity. While it may seem backward, this method allows me to effortlessly search for configuration values and track changes via Git history. I’ve adjusted parameters only three times in three months, saving countless engineering hours through quick redeployments.
3. SQLite: A Low-Stakes Database Solution
Utilizing SQLite for my multi-user web application may raise eyebrows, but with a database size of just 47MB and the ability to support 50 users simultaneously, it functions well. This experience has illuminated my access patterns: 95% reads versus 5% writes, validating that SQLite is the right choice for now. If I’d begun with a more complex setup like Postgres

This post beautifully captures the essence of pragmatic experimentation in early-stage startups. Embracing the “three-month rule” as a structured way to validate or discard solutions is a powerful method to prevent analysis paralysis and focus on real-world insights. I particularly appreciate the emphasis on simplicity—using a single VM, hardcoded configs, and SQLite are excellent examples of avoiding unnecessary complexity during initial phases. This approach not only accelerates learning but also ensures that resources are allocated efficiently toward features and solutions that truly resonate with users.
Additionally, I believe this iterative, fail-fast mindset aligns well with modern development philosophies like Lean Startup and rapid prototyping. As startups scale, these insights can inform when to optimize and transition to more robust infrastructure, but the real value lies here—getting a product out, understanding user needs, and evolving based on that understanding. Thanks for sharing these practical strategies; they’re a valuable reminder that sometimes less truly is more early on.
