Emma and I explain our use of Retool positively (and shout out to Retool for providing it free during the crisis) in this Strangeloop talk: https://www.youtube.com/watch?v=tQPaGpVzjBg
We did a COVID-related PPE supply nonprofit in 2020 and loved Retool, so it was good to be able to give props here. Retool was super generous and helpful to us getting ~1 Million masks to health care workers in the first wave of the pandemic.
