"platinumears" is just me, known as IIRs here on KVR, or Dan Worrall in real life.

I run a small but high quality studio here in Sheffield, UK, providing recording, mixing and mastering services. The "platinumears" range of plugins were all developed for my own use, and are available to download free of charge (donations are always welcome of course!)

NOTE: prices are MSRPs / RRPs / SRPs.
