Have a look over at: TUNE APP.
While we'll focus on entrepreneurs and such as a first niche the scope is definitly much broader. (second one will probably be travelers here)
I (founder) got the first version of the idea while on a world trip. It's hard to stay in touch with everyone across timezones & lifestyles. You're trying to arrange calls, the wifi is bad & you retell the same story over and over. So I tried podcasts & youtube videos, but these took days if not weeks to make. And text messages just fail to convey the excitement or emotion of the adventures. Finally, I switched to sending audio messages via fb & whatsapp and it finally started to click. I still had to send them to everyone individually or make them personal, but there was no easy way to share, tag, edit or save them, or a dedicated place to do so. And it also got me thinking that I would like to follow other peoples lives like that. Short < 5 min updates strung together in an endless feed of different peoples lives. We took it from there.
Twitter, instagram, etc need eyes.
Podcasts can be a bit long or not very personal.
TUNE can keep you in touch with other entrepreneurs, friends & family while walking / cycling / driving / etc. It's easy to share your story & follow others'
Think TIKTOK without the visuals and dancing but longer and with actual depth. So not like TIKTOK at all.
Yes the pitch can use some work too (:
