But it's his work for Mamdani that propelled Katz's name to the national stage.
He told New York Magazine in June that he was taken with the 33-year-old democratic socialist after their first meeting.
"I left thinking, I love this man. And I am supposed to be skeptical. What is going to happen when the rest of New York gets to know him?" the outlet published him saying.
Katz is now reportedly throwing his progressive ad-making chops behind Casar, who is running for his third term representing part of the Austin, Texas area.
Fox News Digital reached out to the Fight Agency and Casar's campaign multiple times for confirmation and further comment but did not receive a response.
Casar's new ad, which runs just over two minutes long, touts his time as a labor organizer and state lawmaker before coming to Congress in January 2023.

"I had hoped that my commitment to reelection under any circumstances would encourage Congressman Casar to not surrender his winnable district to Trump," Doggett said in a statement on Thursday. "While his apparent decision is most unfortunate, I prefer to devote the coming months to fighting Trump tyranny and serving Austin rather than waging a struggle with fellow Democrats. If Trump's extreme gerrymandering prevails, I wish Congressman Casar the best."
Casar said Thursday in response, "Lloyd Doggett is an Austin institution. I’ve learned so much from him. I’m grateful to him. The fight for democracy continues."
He wrote on X Monday morning of his decision to switch districts, "I'll keep fighting Trump's gerrymander. If the new maps hold, I’m running in the new Austin District (37), which includes my home, my city council district, and 250,000 of my current constituents."
