How to Run Multiple 10K MRR Companies on a $20/Month Tech Stack

I often face skepticism from VCs when I pitch my lean, bootstrapped businesses. They wonder why I need funding when my companies are already generating Monthly Recurring Revenue (MRR) and have a dedicated user base. My approach is simple: keep costs minimal and focus on efficiency. This strategy not only extends my runway but also reduces stress and simplifies operations.

## Use a Lean Server

Instead of diving into complex and costly cloud services like AWS, I opt for a single Virtual Private Server (VPS) from providers like Linode or DigitalOcean, costing no more than $10 a month. This setup is sufficient for handling web applications if you manage resources wisely, such as using a swapfile for additional memory.

## Choose a Lean Language

For backend development, I prefer Go over languages like Python or Ruby. Go is efficient, easy to deploy, and well-suited for handling numerous requests with minimal resources. By compiling applications into a single binary, I avoid dependency issues and simplify deployment.

## Leverage Local AI

For AI tasks, I utilize local hardware, like a second-hand RTX 3090 GPU, running VLLM for efficient batch processing. This setup eliminates ongoing API costs and allows for rapid iteration and deployment of AI models. Tools like Ollama and Transformer Lab facilitate model experimentation and deployment.

## Simplify with OpenRouter

For cutting-edge AI interactions, I use OpenRouter to manage API integrations seamlessly. This tool provides access to various AI models without the hassle of multiple accounts and complex fallback logic, ensuring consistent service for users.

## Opt for Cost-Effective Development Tools

Instead of expensive AI IDEs, I rely on GitHub Copilot for coding assistance. Its pricing model allows for extensive use at a fraction of the cost, enabling detailed prompt-based development without breaking the bank.

## Use SQLite for Databases

I start projects with SQLite, which offers speed and simplicity over traditional database servers. By enabling Write-Ahead Logging, SQLite can handle high concurrency, making it suitable for many applications. I also developed a library to streamline user authentication, further simplifying project setup.

In conclusion, the tech industry often overcomplicates business building. By focusing on cost-effective tools and strategies, it's possible to create scalable startups without hefty expenses or venture capital.
