Good Ventures LLC is a for-profit investment subsidiary of the Good Ventures Foundation. Created in 2012, it donates its net earnings to the Good Ventures Foundation to support grantmaking in the areas of left-of-center criminal justice reform, farm animal welfare, pandemic preparation, and scientific research.  Good Ventures LLC supports for-profit organizations working to improve disease testing, develop medical therapies, and support COVID-19 vaccine research.
Good Ventures LLC, along with the Good Ventures Foundation, supports organizations at the recommendation of Open Philanthropy, a center-left funding nonprofit. Rather than donating to an organization because of its nonprofit tax-status, Good Ventures LLC invests in various for-profit ventures aligned with Good Ventures Foundation’s left-of-center agenda. 
In 2021, at the recommendation of Open Philanthropy, Good Ventures LLC invested in OliLux Biosciences for the development of diagnostic and treatment tools for tuberculosis. In 2020, Good Ventures LLC invested in VasoRX, a biotech company launched by researchers at Yale and MIT to develop new testing and therapy for vascular diseases. 
In response to the COVID-19 pandemic in 2020, Good Ventures invested in a point-of-care diagnostic platform company called Binx, to support the incorporation of Sherlock Biosciences’ COVID-19 assay into Binx’s diagnostic platform. It also invested in a new drug candidate against COVID-19 being developed by Riboscience and a nanoparticle COVID-19 vaccine being developed by Icosavax. 
In 2018, EicOsis received a $5 million investment from Good Ventures LLC for its development of an oral treatment for neuropathic and inflammatory pain.
