Ask HN: Where to invest 200k / year

I own a software company and it profits about 200k a year, after all expenses, including my salary and tax. Its not a big business but it works great and i love what i do... I dont want to remove the money from the company (as a dividend to me), as i would pay a lot of tax again and i dont need it personally. Its also hard to re-invest that money in the software company, because i just do client projects, have some contractors and a most depends on me doing it myself. All i could do is invest in marketing and hope for bigger projects which can be done by employees, but that seems like a shot into the blue... Also i have no clue where to start on this.

So the question is what to do with it... I dont like traditional investments like stocks or index, and i am not sure about real estate...

I used a part and started a mining farm at a local water power plant... its fun and works quite well... but i dont want to put too much into crypto =) I also plan to put some into peer-to-peer lending.. but also, no significant amounts.

I would like to invest in some semi-automated businesses... like lending cars, renewable energy plants... something which requires some amount of time, money and maybe technical expertise (like setting up a website or some required software stuff), but it should be able to run either mostly on itself or by employees on the long term.

Maybe i would also be happy to do small angel-invests (40-70k) into companies which need some technical expertise as well.. I dont really care for the risk of the investment as i am not hurt if the money is gone, but for sure i will verify if the potential payoff is in relation to the risk.

any ideas ?
