Which EV charging companies offer B2B or B2C investment opportunities?

I've been doing some research into the EV charging space and I'm trying to better understand which companies allow outside investment, beyond simply hosting or operating a charger.
Specifically, I'm curious if there are EV charging networks that support: • B2B investment models (where businesses can own or co-own chargers) • B2C investment models (where individuals can invest in chargers or participate in revenue sharing)
I'm already aware of companies like EVgo, ChargePoint, and Voltanio, but it's not always clear which of these actually allow ownership or investment versus just site hosting or network participation.
If anyone has experience or insights into companies that truly offer B2B or B2C investment options in this space, I'd appreciate hearing about it.
