My readlist in French is https://www.journalduhacker.net/ , as suggested in another comment, and https://linuxfr.org/, covering open source, if it applies to your product. Then Hackernews, but you are already here. Appart from that, it depends on your product. You will need to communicate through the niche channels your SaaS is adressing (aka woodworking channels for a woodworking Saas, etc ...)

Biggest IT news site in Germany is heise.de, they also have a catalogue with software and service providers - you can contact their team at software@heise.de (if it's a commercial proposal with subject: "Kommerzielle Listung bei heise Download" according to their FAQ at https://www.heise.de/download/page/Haeufig-gestellte-Fragen-... )

Sorry that my comment provides little to no value to the original question: being a native Spanish speaker from Latin America, in my 10 years in IT, I have been so far unable to find a site that comes close to any tech forum or something like Hacker News. I agree with franciscop that there should be a Spanish Hacker News. The problem is: what content would it be fed with, as quality content is scarce.

There are some in Spanish

https://elreferente.es/

https://startupslatam.com/

https://loogic.com/

https://startupchile.org/en/

For french, there's a decent website similar to Product Hunt: https://lespepitestech.com/

It has a good following and a weekly e-mail list so it's probably worth it to post there as well

French: https://www.journalduhacker.net/

European: https://starwatcher.io

Relevant only if you want to get some exposure to european investors though.

The Next Web: https://thenextweb.com/

For French PR: - https://www.maddyness.com/ - https://www.frenchweb.fr/ - https://www.presse-citron.net/ - https://www.journaldunet.com/ - https://www.rudebaguette.com/

I don't know of any significant Spanish website where you can feature your startup. The Spanish speaking community is mostly featured in English websites. Websites in Spanish are too fragmented.

For Portugal you might contact https://startupportugal.com/

This one is an official website for a government program, but I think it's for Portuguese companies https://portugaldigital.gov.pt/acelerar-a-transicao-digital-...

Only half related to Op’s question but I’m thinking a lot about this right now as i just translated my iPhone app to 11 languages and released the update a week ago. I see NO additional downloads and I’m really curious to why. If anyone here has some experience or insight I’d really love to hear about it.

This reminds me I've talked a dozen times with a friend whether we should start a "Spanish Hacker News", right now the closest thing is small dev Slacks on a per-city basis.

Heads up, "Portuguese" you mean Portugal, Brazil, and/or Africa? Those audiences are completely different in size, ticket, and so on.

For the Portuguese market you can try Pplware [1]

Expanding from OPs question, but how about a Chinese website along same lines?
