Stream Research Group
Stream is a content library of transcribed expert interviews, launched by expert network Mosaic Research in early 2020, and acquired by Alphasense in October 2021. Alphasense communicated that Stream will continue to operate as an independent entity, only integrating Alphasense's text processing tech and cross-selling the content library to Alphasense's existing clients.
Expert call transcript library
As per March 2021, the Mosaic Stream product contains around 3,000 transcripts of expert calls, adding almost 300 transcripts/month. At the time Alphasense acquired it, the database had grown to 8,500 transcripts, implying a growth rate of close to 800 new transcripts per month.
The model is similar to Tegus: investment professionals and company employees conduct expert calls (at low or no cost) which are transcribed and added to a library. Other investors subscribe to the library, and may conduct expert calls as well.
The experts may or may not get compensated for their participation.
