I've been meeting with startup marketers over the last few weeks to better understand how they are generating demand, whether with a sales force or strictly PLG. It got me thinking how much it takes to really build a startup [successful or not!] Here's a peak into ours.
These are just some of my favorite tools - I know there's a ton more out there.

This is the tech stack I rely on to build and launch fully functional apps within a week. After years of experimenting with different combinations and shipping six failed products, I’ve refined a setup that balances speed, flexibility, and ease of use—especially for solo developers. It lets me move fast, iterate quickly, and get real feedback without getting bogged down in infrastructure or boilerplate. Below is a breakdown of the tools I use across frontend, backend, mobile, deployment, auth, and analytics.

Before moving onto my third startup, I wanted to take a step back, reflect on what I've done and create a good base for future startups. Which is why I've decided to write down my tech stack and create some boilerplate code for my future startups. I hope sharing this can help you build your startup!
Here are the tools that will allow you to launch your first SaaS in 21 Days.
