Development of the play began in 2014, when Koechlin wrote a four-page conversation between Death and an old woman who is in a strange surreal space, about to die but unwilling to exit the world. She further worked on the script of the play in 2015. In a 2016 interview with Mumbai Mirror she said, "Last year, when I was unemployed for six months, I started fleshing out the story. It turned into a comedy on life and death". The play was staged at the Ranga Shankara Hall, Bangalore, on 24 July 2015. Koechlin also worked in Rajat Kapoor's What's Done, Is Done, an adaptation of Shakespeare's tragedy Macbeth. She played Lady Macbeth and doubled up as one of the witches for the play. The first show of the play was staged on 5 June 2016 in Mumbai. Philanthropy Koechlin identifies herself as a feminist and extensively campaigns for the cause of gender equality. She wrote an article on gender pay-gap for 22 August 2014 issue of Forbes India, and is vocal in her support for the issue: "Equal pay won't happen because there is a hero-based industry [...] need to strive for scripts that empower women, make women our heroes, too."

She appeared in Puma's "Do You?" advertisement campaign which encouraged women to, "find their best self". Koechlin, alongside Jacqueline Fernandez and Sakshi Malik led a group of women at an event, organised as part of the movement, to break the Guinness World Record of "Most people to hold the abdominal plank position" for 1 minute.
