Plot summary
Keenan Feldspar put a rider in his contract so he can leave Bream-Hall if Erlich does. Due to a cold snap and consequent insurance claims, FGI has unexpected data processing requirements and the team faces a huge bill from their storage provider. Needing another client, they pitch to Feldspar. Dinesh and Gilfoyle are sucked into his VR project which they improve with middle-out compression. Feldspar offers to acquire Pied Piper; Richard tries to bluff with a valuation of $25 million, which Keenan accepts. Feldspar gets the money by pitching his improved VR to another firm, receiving triple Bream-Hall's advance, and convincing Erlich to quit.
Monica warns Richard that Feldspar's VR tech is a bloated demo that can never be fully realized, which he is hyping for quick money. She promises to fund their series A round if they can implement the decentralized internet project on a sufficient number of smartphones. Feldspar sells his company to Hooli, the only other company with middle-out compression, as Barker's box2 faced setbacks and he desperately needs something to showcase at the upcoming Hooli-Con tech conference. Erlich is left out of the Hooli deal with nothing to show for it.
