raising a pre-seed round for a social music platform

Hi everyone!

I've co-founded a social music platform and we're a couple weeks away from launching our iOS app. My team and I would love some advice from other founders and investors in the consumer/ social media or music space to learn from others experiences raising a pre-seed round. We do have some initial traction via pre-orders, instagram and partnerships.

Aside from traction, what should social media platforms flex in their pitch?

Congrats! Best of luck on the journey!
Thank you so much!
