Commsor was a community and go-to-network software company founded by 📝Mac Reddin. It launched as a "community operating system" — integrating common tools to tie community data together so companies could unlock insights, measure impact, and build community-led businesses — before pivoting to curated warm introductions as a sales channel. The company was acquired by 📝The Swarm, which announced it would wind down Commsor's products while folding its best features into its own network platform.

In its community-era years, Commsor built an ecosystem beyond the core product: C School, an education program for community managers, and The 📝Community Club, a community for community professionals. As the "community-led growth" wave crested, Reddin repositioned the 13-person company around the go-to-network movement — the thesis that warm intros and referrals close faster, spend more, and churn less than cold outbound. Its backers included 📝Alexis Ohanian. Across six years, Commsor helped shape how the industry thinks about community and relationships in go-to-market.
