Founders benefit more from inexperienced friends who push them to action.

A blend of experience and youthful nativity is the perfect mix. I agree that inexperience can be a huge benefit in tackling problems in different ways and having an irrational confidence to go after opportunities that others may avoid. A guiding hand is always helpful to avoid learned mistakes and leverage best practices

Founders benefit from FRIENDS, period. If you're paying attention to the news these days, you'd see that this is the loneliest time in history. People have less friends than they ever have, less romantic partners, and just generally less social relationships. It's pretty sad.

So I'd say it's less important whether your friends are experienced or inexperienced, and it's more important that you just have friends at all. It sounds crazy, but most people (I'm no exception) are lucky to have 1-3 good friends. It's an unfortunate world we live, but friends are hard to come by, and their impact is important, regardless of their professional background.

Curse of knowledge is a real thing, and I always like to discuss problems with external parties with no skin in the game to make sure my messaging is clear or if I'm going in the right direction

For me, it really depends. My friends who are inexperienced in entrepreneurship / Indie Hacking tend to be less supportive. Even when they're trying, it's often redundant - "don't worry," "keep going," doesn't mean much when they don't understand the gravity of what I'm facing or the sacrifice that attempting to fix something would entail.

This is an interesting thought. Something I believe in and much of the basis for Oxogen.io. Different perspectives are vital for startups.

I think both have value but the inexperienced friends ask naive questions and have a point of view probably closer to your target market.
