I guess company directory is still the best place to look for this type of job. If you email the new companies who just got the pre-seed, I'm sure you can get low salary/high equity job if the connection is there.

Just email them even they're not hiring at the moment.

If you're aiming for remote opportunities, you could try platforms like Upwork or Fiverr since low pay doesn't bother you!!

But if you're genuinely looking for startups only, I would say try X.

If I may ask, why would you go for lower pay to work with a startup?
