What are the opportunities to sit on boards or advisory boards for startups?

Startups are often looking for people with marketing, sales, and executive experience, so board positions are available for those who want them. There's an important tax benefit to consider: if you take a board position and move to Portugal for more than 183 days per year, you can qualify for the non-habitual residence 2.0 program offering a 20% flat rate on Portugal income.
