In September 2015, Dunham and Konner started Lenny Letter as a self-funded project that would give a platform to young female voices to discuss feminist issues. The newsletter features political essays, personal stories, interviews, artwork and even an advice column from Dunham and Konner themselves called "Letters to Lenny." Benjamin Cooley is the CEO. Laia Garcia has been Deputy Editor since July 2015.
Notable articles include an essay written by actress Jennifer Lawrence about the gender wage gap in Hollywood, and one written by singer Alicia Keys about her decision to start wearing little to no make-up.
In addition to the regular newsletter, Lenny Letter published a Fiction Issue and a Poetry Issue during fall 2015. Lenny Letter is developing a possible HBO short film series.
In November 2017, following Dunham and Konner's controversial letter denouncing Aurora Perrineau's accusation of sexual assault by Murray Miller, Zinzi Clemmons announced that she would no longer contribute to the newsletter, saying Dunham's racism was "well-known" and called for all women of color to "divest" from Dunham.
