Today the company Krisiloff started, called Conception, is the largest commercial venture pursuing what’s called in vitro gametogenesis, which refers to turning adult cells into gametes—sperm or egg cells. It employs around 16 scientists and has raised $20 million from well-known tech figures including Sam Altman, the CEO of OpenAI and former president of Y Combinator; Jaan Tallinn, one of the founders of Skype; and Blake Borgeson, a cofounder of Recursion Pharmaceuticals.
