[Assuming that you're referring to Sierra Space and their https://en.wikipedia.org/wiki/Dream_Chaser#Crewed_version]

Note that the Crew version still seems to be aspirational. And the base-model Cargo version isn't exactly flying in the fast lane, either - "[first] demonstration mission is planned for launch no earlier than 2025."

And note that it took SpaceX almost 10 years to go from Demo-1 of their Cargo Dragon to Demo-1 of their Crew Dragon.
