Note that your site currently doesn't work in Safari (desktop or mobile). A quick glance at the error console shows that you're using the Fetch API [1]. Polyfills are available.
Have you tried running any adverts? Ultimately, I suspect it comes down to either running a marketing campaign yourself or networking enough to find someone else who's prepared to handle that side.
turns out I have been developing the site on safari tech preview and fetch api is only supported on tech preview! Thanks for the feedback.. I'll work on this.
You can use this polyfill and it should work: https://github.com/github/fetch
