Startup Idea: Cross-Platform Social Media Scheduling Software

Startup idea to develop a cross-platform scheduling software that allows a social media manager to schedule posts across all platforms, including Instagram and Snapchat stories.

I am a social media manager and their is no scheduling software that I can use across all platforms. Currently,

I can use Hootsuite for Facebook and Twitter, but unfortunately I cannot schedule my Instagram posts their. I am also unable to use a scheduling platform to schedule out stories on Snapchat and Instagram.

This makes my job 24/7 even when I have preplanned posts to go out on my brand's stories.
