1. How fast is you want/have to deliver first iteration + what’s your long term company strategy (eg how fast you want to go for founds vs you would like to develop organic) = tech debt you can take.

For example if you wed to deliver fast and have plans for external founds I would go for Wordpress/PowerPoint or whatever allows me to show anything today or tomorrow to not waste time.

If you have more time/what to grow organic you have to keep in mind tech debt which might bite you in worst possible moment.

2. What problem you would like to solve?

Tech stack it’s just set of tools, nothing else. So saying I will choose hammer to build Swiss watch because my team know hammers in general and it’s more secure than screwdriver is accurate as choosing tech stack for same reasons.
