The IWMF, based in Washington, funded the Swedish journalist on a reporting trip to Sri Lanka and supported her on a reporting trip to Uganda last year, led by Nadine Hoffman.
Nadine Hoffman, deputy director of the IWMF, remembers a gifted journalist with a vibrant personality.
"This is really devastating news for us, for the International Women's Media Foundation and for the community of journalists that we consider to be our family. Kim was really loved by many in our network who knew her and worked with her. So it's a loss for all of us," she told Radio Sweden.
Kim was really a vivacious person. She ws just such a magnetic personality. People really gravitated to her. Her sense of humour is the thing I'll always remember about her."
The 30-year-old, who grew up in Trelleborg in southern Sweden, reported on conflicts, crises and natural disasters around the world but also covered stories not often featured in mainstream journalism, according to Nadine Hoffman at the IWMF.
"She found those human interest stories that not everyone was looking at. She came from a really unique perpective.She was talking about people's experiences you would never have heard about if she had not reported on it."
Kim Wall was at risk reporting from some of the world's hotspots, but it was closer to home in Denmark where her body was found on Monday. She had gone missing after going for an interview with a Danish inventor on board his submarine.
It is a horrible irony for Nadine Hoffman, who told Radio Sweden that her organisation had given Ms Wall hostile environment training last year.
I think for us at the IWMF our highest priority is journalist safety. We do provide hostile enviornment training for every journalist we take into the field. Kim had that training with us last year. You expect that there will be a risk when you work in a conflict environment and I think in this case it's just a risk that no one could have anticipated."
The Danish prosecutor holding the Danish inventor on manslaughter charges, told media, Thursday that he is looking at a murder charge.
