what i would do if i were you in a list :
- asap targeting your end-user that could be transit people like foreigners within meetups or interested in events or wework spaces e.g.
-digital media is the key: get a 10 min coffee and network about why you are differentiating yourself.
- and sample stuff like no others. Go to NYC and create a meetup or find embassadors and pay them a commission for example.
