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. This program offers a 20% flat rate on Portugal income and 0% on income earned outside Portugal, and there's no inheritance tax in Portugal, which is good for estate planning. However, board of advisors positions don't qualify for these tax benefits. Taking a board position is not required for the Golden Visa and is only relevant if you want to move to Portugal full-time. That said, if you're interested in it for its own sake, it can be fun and fascinating work.
