Documented cause
Tandem, founded by Rajiv Ayyangar and Brian Paget in 2018, raised $9M to create a virtual co-working space that let remote teammates work side-by-side via audio. The product gained strong traction in 2020 but could not achieve sustainable retention as hybrid work normalized. In April 2022, Tandem was acqui-hired by Loom (which was itself later acquired by Atlassian) for an undisclosed sub-$10M sum, effectively shutting the standalone product.
Lesson
“Building ambient presence tools requires network effects that are nearly impossible to build without viral B2C distribution.”
