Embracing the 3-Month Rule: A Pragmatic Approach to Non-Scalable Solutions
In the dynamic world of start-ups, the conventional wisdom from tech luminary Paul Graham resonates deeply: “Do things that don’t scale.” Yet, the conversation often lacks pragmatic advice on how to apply this tenet effectively, especially when it comes to coding.
Having spent the last eight months developing my AI podcast platform, I’ve crafted a framework that I affectionately call the “3-Month Rule.” This guideline dictates that any non-scalable hack I implement must survive for only three months. After this period, if it hasn’t proven its value, it’s time to let it go.
As developers, we often gravitate toward creating scalable architectures right from the start. We think microservices, distributed systems, and other sophisticated frameworksΓÇöall designed for extensive user bases. However, in the early days of a startup, striving for scalability can often mean delaying real progress.
IΓÇÖve found that adopting my 3-month rule compels me to write straightforward, unrefined code that is deployable. This approach accelerates my understanding of user needs, rather than deferring it with intricate designs for hypothetical users.
HereΓÇÖs a Peek at My Current Unconventional Infrastructure Choices:
1. Operating on a Single VM
I’ve consolidated everything╬ô├ç├╢database, web server, background jobs, and caching╬ô├ç├╢onto one $40 monthly virtual machine. My setup carries no redundancy and relies on manual backups.
This might seem careless, but it has proven invaluable. Within just two months, IΓÇÖve gained insights into my resource consumption far beyond what any formal planning document could provide. My platform, which I presumed would be resource-intensive, actually peaks at 4GB of RAM. The complex Kubernetes framework I considered would merely have been managing idle containers.
Each time the system crashes (which has occurred twice), I obtain concrete insights into what truly fails, often revealing surprises about my assumptions.
2. Hardcoded Configuration Values
Instead of relying on configuration files or environment variables, IΓÇÖve chosen a straightforward method using hardcoded constants:
python
PRICE_TIER_1 = 9.99
PRICE_TIER_2 = 19.99
MAX_USERS = 100
AI_MODEL = "gpt-4"
This setup allows me to quickly locate configuration values across my codebase. Changes in pricing or parameters only require a minute of redeployment, sparing me extensive development time that setting

This is such a pragmatic and insightful approach to early-stage development. The 3-Month Rule effectively balances the need for rapid learning with practical constraints, allowing for quick experimentation without getting bogged down by over-engineering.
I particularly appreciate your emphasis on leveraging simple, non-scalable solutions to gain concrete feedback. The single VM setup, for instance, reminds me of the concept of ΓÇ£Doing the simplest thing that could possibly work,ΓÇ¥ which often yields invaluable insights that more complex architectures might obscure.
Additionally, your choice to hardcode configuration values highlights the importance of prioritizationΓÇömaking quick changes without the overhead of managing multiple config files can significantly accelerate iteration cycles. Of course, as the project matures, a transition to more scalable and maintainable practices will be essential, but your framework provides a solid foundation for making informed decisions along the way.
This approach resonates deeply with the ethos of lean startup methodologyΓÇötest fast, learn quickly, and iterate based on real data. Thanks for sharing this practical perspective!
This framework offers a compelling perspective on balancing speed and learnings in early-stage development. The ΓÇ£3-Month RuleΓÇ¥ emphasizes the importance of rapid experimentation and avoiding over-engineering, which aligns well with lean startup principles.
From my experience, embracing intentionally “non-scalable” solutions in the short term can accelerate iteration cycles╬ô├ç├╢especially when testing core hypotheses or onboarding initial users. Your approach to using a single VM and hardcoded configs exemplifies what Eric Ries called ╬ô├ç┬úminimum viable product╬ô├ç┬Ñ tactics, focusing on validated learning rather than perfect infrastructure from the start.
However, itΓÇÖs also valuable to recognize that this approach can expose risksΓÇösuch as reduced resilience and potential technical debtΓÇöthat should be addressed as the product scales. Balancing the current pragmatism with a plan to refactor into scalable architecture later ensures sustainability.
In essence, your framework champions a disciplined, time-bound experimentation mindset that can significantly shorten the path from idea to validated product, provided itΓÇÖs accompanied by mindful planning for eventual scalability.
