Apart has been useful for me to quickly experiment with ideas/improve on quick iteration. I've organised multiple hackathons before knowing apart, and their format is vastly more effective at converting talent/by unit of effort. While I was head of EffiSciences’ AI Safety Unit, this was one of my favorite event formats, and this is one of the format that I encourage alumni of ML4Good to run. Empirically, each apart hackathon that I organized in Paris enabled the long term careers of 0.6 person in AI Safety (see the table). This means that, on average, 0.6 new full-time persons started working on AI safety after each Apart hackathon event in Paris.
