I wrote "Piece of P *I S S" but it blurred it out.Sorry @Brad93 , but the world runs on VFDs, or VSDs to give them their other name. The bigger ones tend to be 3ph in 3ph out though. Starting out with 240 is not good, nor is running a motor at 230v 3ph, but mostly it gets the job done.
You can get voltage doubling VSDs that put out 400v 3ph, but they are not cheap, and sometimes get you into trouble - my Fritz Werner mill was blowing output and driver stages one after the other, I kept fixing it until I ran out of spares, but in the end found out the real culprit - the forward reverse switch buried in the machine had got damp and was tracking across. I hate to think how much in time and money that mistake cost me...
I'd use a VFD
