Tokamak Energy has made 3 fusion devices in 11 years. It's not super fast, but certainly faster than the megaprojects. They are planning on their current design

  Indeed, Tokamak Energy's whole strategy hinges on fast iteration [1]: "The basic approach being taken by Tokamak Energy is simple—to combine the two aforementioned technologies to unlock the potential of fusion power in more compact devices, and to do whatever development, testing and iteration are necessary on smaller machines in order to reduce construction timescales and to progress faster." As of January 2020, Tokamak Energy had raised a total of £117 milllion (~$156 million). I read that SpaceX has raised $5.4 billion [3]. That's the limiting factor.
