Real estate crowdfunding and startups as an alternative to ETFs: are you convinced or not?

I'm 26 years old and have been investing in ETFs for 8 years. For some time now, I've been thinking about allocating part of my investments to more "tangible" activities where I could potentially provide direct support to the team.

I'm considering allocating part of my new liquidity to real estate crowdfunding (Walliance, Leone Investments) and startup equity (Mamacrowd, Opstart), all CONSOB-authorized. Reported returns are 7–12% per year on real estate, with a possible 3–10% return on startups with a total loss risk. Returns aren't the key.

A significant tax bonus: investing in innovative startups deducts 30% of your personal income tax (IRPEF). Capital gains reinvested in another startup within 3 years aren't taxed at 26%.

**Would you do it? Does anyone have any direct, positive or negative experiences? I'm especially curious to know why you did it, or why you chose not to.**
