You do have btcstock exchanges like Havelock(that rentalstarte is on), cryptostocks and so on, bitcoin lending platforrms like btcjam, croudfunding places like kickstarter, but you probably need to check up how to comply with rules with someone who knows exactly how it works like MSantori https://bitcointalk.org/index.php?action=profile;u=118100 here on bitcointalk if your in the usa & or your company is there or you seek funds from us citizens, rules & regulation over there seems to be a bit complicated even for smaller projects.
