CRM or Accounting SaaS for nano-influencers?

Hi everybody !
I am a web software engineer and I would like to launch a SaaS for nano influencers and social marketers.

I have found lots of solutions for entreprise teams (Buffer, ect…) to schedule, do analytics and stuff. Also some SaaS matching influencers and companies.

What I would like to build is like a CRM but FOR the influencer, with accounting, payments features, ect…

I am currently looking for influencers and social marketers who might be interested by such a product. I would like to understand what are your pain points and, if you are willing to, become beta users to help me build a custom made solution !

Cheers !
