We enable organizations to reach their audiences through trusted messengers.
We're SoSha.
Our platform makes it easy for organizations to leverage the social clout of their communities to spur organic growth by providing their audiences with shareable social content and helping them track the engagement of the posts shared.
Who We Are
SoSha was founded in September 2019 with a clear mission: help organizations communicate at scale without losing authenticity.
Organizations have more technology than ever — yet reaching the right audiences is harder than ever. For years, paid media has grown more expensive and saturated, organic reach has been throttled, and trust in institutions has declined.
SoSha was founded on the belief that the future of communications belongs to communities. Our mission is to turn communities into distribution channels — empowering real people to share messages they believe in, and making that sharing measurable, optimizable, and scalable.
Everything we build — from our embeddable social share toolkits to our predictive AI and closed-loop analytics — helps organizations transform one-way messaging into authentic, peer-driven amplification.
Because when trusted messengers share the story, audiences listen.
