We help organizations activate the social clout of their communities.
We're SoSha.
Our platform makes it easy to build shareable content, get it into supporters’ hands to share on their own accounts, and measure engagement so you can iterate quickly.
Your goals drive our roadmap. We want to help you unlock social media amplification, so every update focuses on speed, ease of use, and measurable results.
Who We Are
SoSha was founded in September 2019 with a clear mission: help organizations communicate at scale without losing authenticity.
Organizations have more tech options 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.

Using the right tools makes your marketing team more efficient, freeing you up to focus on the bigger picture things and think more cohesively about what your organization can do as a whole. Toolkits like SoSha’s abandon the “one thing at a time” mentality, allowing you to think through a solid comms plan and expedite and grow to bigger audiences.
