Specifically for our company that is a hotel/managed Airbnb (ohotelsuites.com) and we are just relaunching our brand and platform in 3 weeks.
I agree with other responses, crowdfunding is not an appropriate channel for your business model. What is the value proposition that you offer to condo owners and people renting the place? Do you have an exclusive relationship with condo owners? Unfortunately, social media marketing is NOT FREE these days, paid social media marketing for B2C products is significant expense for all new high growth companies and I am not sure that's the best way to keep acquiring customers for you.
