Join me in conversation with Sarah Zeng, who has gone from investing to operating at the forefront of AI - first as one of the first 50 employees at Character AI and now scaling Braintrust. Braintrust is a go-to platform for AI evals and observability. They recently announced their $80M Series B, led by ICONIQ and joined by returnees a16z, Greylock, Elad Gil, basecase and others.
