Thank you @revcd and @ben for sharing your approach! I haven't had time to properly go through everything but as soon as I do, I'll share my learnings.

So happy to read your feedback, Pieter! Portugal is definitely a small market and my main goal is to create some value for the local startup scene. Not expecting to pay the bills and I do agree with @marc when he says that the difficult part is having a targeted audience that employers are willing to advertise their job listings to.

The job board would be be connected to a Slack community focused on the Portuguese startup scene (already exists) and my hope is to work alongside incubators and coworking spaces to make it more relevant.

I didn't think about SEO optimisation. Thank you for the tip!

If your target are people who are not too tech savvy, I would go for the .com domain. Having that in mind, this is not enough information! What else can you tell us about your customer and their journey (how would they find out about you, get to the website, get the product)?
