Allied Progress is a project of the New Venture Fund, a left-of-center funding organization characterized by critics as a “dark money outfit.”   It has a sister organization, Allied Progress Action, which is a project of the Sixteen Thirty Fund.
However, as of January 2020, Accountable.US (another New Venture Fund project) has claimed control of Allied Progress. Accountable.US notes that it is “in the process of transitioning from the New Venture Fund” into a standalone nonprofit. 
Allied Progress has strongly criticized Trump administration officials, launching a campaign called “Defending the Consumer Bureau” against Consumer Financial Protection Bureau acting director Mick Mulvaney.
In May 2018, the Washington Free Beacon reported on Allied Progress’ status as a fiscal sponsor (or project) of the New Venture Fund, a major left-of-center grantmaking organization affiliated with Clinton operative Eric Kessler that has received funding from left-wing sponsors such as George Soros’s Open Society Foundations. The New Ventured Fund has been criticized as a “dark money” organization for funding its fiscal sponsorship of activist organizations such as Allied Progress, a practice which obscures donors to the activist groups. 
Criticism of Trump Administration
Allied Progress signed a letter condemning the immigration policy of the Trump Administration and urging American CEOs not to employ anyone involved with the policy. It accused these officials of being directly guilty for physical abuse, sexual assault, and even the death of illegal immigrant children. The letter was titled “An Open Letter to America’s CEOs” and was dated April 6, 2019.
