Richard steps down as CEO of Pied Piper, and instead begins working on a new project: a decentralized, peer-to-peer internet, that would be powered by a network of cell phones without any firewalls, viruses, or government regulations. Gavin Belson is removed as CEO of Hooli after an incident involving COPPA violations from when he seized PiperChat. Jack Barker takes his place as CEO. Gavin temporarily works with Richard, until he has an existential crisis and leaves Palo Alto for Tibet. Laurie and Monica form their own VC company, Bream-Hall. Big Head becomes a lecturer at Stanford University’s Department of Computer Science. Erlich gets into business with Keenan Feldspar, whose VR headset is the Valley’s latest sensation. However, Erlich is left out of a signing deal and is abandoned by Feldspar, leaving Erlich disillusioned. Erlich then goes to Tibet to meet with Gavin. Gavin meets up with Erlich in Tibet. Belson eventually returns home, while Erlich stays behind. Richard gets into business with FGI, an insurance company, who uses Pied Piper for their data storage needs. After a crisis involving FGI’s data storage, the team discovers that the decentralized internet is a working concept after the data from their Pied Piper server had backed itself up to Jian-Yang’s smart refrigerator, as Gilfoyle used some of the Pied Piper code when he was trying to hack it, which in turn connected itself to a network of other refrigerators like it and distributing the data. Gavin ousts Jack from Hooli and regains his position as CEO. He offers a very generous acquisition deal to Richard, who turns it down and decides to be funded by Bream-Hall.

Silicon Valley (Season 4) Episodes

Silicon Valley S4, Episode 1: "Success Failure"

April 23, 2017
Pied Piper officially pivots to PiperChat, a video chat app created by Dinesh, which is steadily gaining users and is superior to all competitors. However, the team is unable to gain funding due to the scandal of their click farm upticks and demise of the compression platform. After clashing with Dinesh and Gilfoyle over the development of the app and attempting to gain investment from Hanneman, Richard realizes that he can't be the CEO of a project he doesn't believe in. Just as the team prepares to replace him with Big Head, he quits his position and signs over his equity in exchange for use of his algorithm and the Pied Piper brand in the pursuit of a more ambitious goal: a decentralized internet based on users and smartphones instead of large companies and mainframes. He suggests Dinesh become the CEO of PiperChat, which was his creation. Meanwhile, Gavin Belson and Jack Barker are returning from China after closing a deal to manufacture Hooli Endframe's box. Belson becomes irked that Jack diverts the plane for his own convenience while lying about it, and "promotes" Jack by assigning him a position at a desk in Hooli's data center, deep underground.

Silicon Valley S4, Episode 2: "Terms of Service"

April 30, 2017
PiperChat gathers attention from investors and a steady stream of daily active users (DAUs), while Richard keeps working on his "new internet" project. Richard finds that Dinesh has blocked him from PiperChat's data repository, violating a verbal agreement. After Big Head gives him login access, Richard learns that a third of PiperChat's users are children, and the app's terms of service never included parental permission. This violates the Children's Online Privacy Protection Act (COPPA) and can incur a total penalty of $21 billion. Meanwhile, Barker embraces his demotion to the data center underground, but Belson is suspicious and spies on his video chat sessions. Since Barker uses PiperChat, with unbreakable encryption, Belson determines to acquire the company. He accuses Dinesh of stealing Hooli Chat's tech and threatens lawsuits, demanding he sign over the company – without a legal assessment. Dinesh does so, knowing that this will make Hooli responsible for the $21 billion fine. Meanwhile, Erlich learns that Jian-Yang has investment meetings and makes a deal with him for 10% of his company; later, he finds out the app is not about Oculus VR but about recipes to cook octopus.

Silicon Valley S4, Episode 3: "Intellectual Property"

May 7, 2017
Gavin Belson is fired following the disastrous acquisition of PiperChat. He is replaced by Jack Barker, who has found a way to avoid the COPPA fines. During Jian-Yang's pitch, Erlich convinces venture capitalists that Jian-Yang's app is actually a "Shazam for food". He hires Dinesh to help write a demo. Monica tricks Raviga's new rising star, Ed Chen, into making a sight-unseen offer for the app, but Chen quickly finds out that there is no product after speaking to Jian-Yang. As revenge, Chen has Monica put in charge of the investment. Big Head applies to Stanford University; he is rejected for enrollment, but the admissions officer invites him to be a guest lecturer based on his name recognition and executive experience. Meanwhile, Richard learns from Monica that Peter Gregory thought of a decentralized Internet in the 1990s, and gains access to his archives. He finds Gregory came to the same conclusions, but the compression wasn't good enough back then. Richard then realizes that this is the best manifestation for his compression algorithm. However, Richard discovers that the new Internet idea was patented by Gavin Belson when he was founding Hooli with Gregory and others.

Silicon Valley S4, Episode 4: "Teambuilding Exercise"

May 14, 2017
Gavin is reluctant to build Richard's idea, but agrees in order to get revenge on Hooli. Knowing his team would never work for Gavin, Richard assembles outside coders to build the platform, but adds Gilfoyle and Jared, who admit they want to be on the team. Jian-Yang tests his SeeFood app, but it only recognizes if something is a hot dog or not. Angry and dissatisfied with the work, he refuses to add more foods to the app. Erlich angrily snaps a picture of his penis, which the app recognizes as a hot dog. Jian-Yang spends all the initial funding on a Corvette. Erlich convinces Big Head to make his students train the image recognition neural net as an assignment. Immediately understanding Erlich's motive, they meet with Coleman Blair Partners and create their own food-based app instead, beating SeeFood to market. Considering his shares of Jian-Yang's app worthless, Erlich trades them for Jian-Yang's Corvette. However, Jian-Yang manages to use Erlich's penis picture to pivot the project as a filter for "dick pics" and Periscope acquires the app. Dinesh is brought into Periscope where his main duty is scrubbing pictures of penises from the Internet, for which he is mocked by Gilfoyle.

Silicon Valley S4, Episode 5: "The Blood Boy"

May 21, 2017
Richard presents the business plan for the decentralized internet project, wanting a discreet launch beginning with a free compression app which will accumulate decentralized storage space on users' devices. Bryce, a jock who regularly donates blood to Belson, influences Belson to rethink the strategy. Richard and Jared warn Bryce not to interfere with their company. Belson demands that Richard apologizes, and he visits Bryce, eventually discovering that he actually consumes marijuana and sugary snacks and is not as healthy as Belson believes. Meanwhile, Erlich predicts that Ed Chen is planning to force Laurie out of Raviga. When Monica tries to warn her, Laurie says she knew about it and rewards Monica's loyalty with an invitation to be her partner on a new VC firm, as she had planned to exit Raviga with a number of investors. Dinesh is paranoid about Mia and doesn't have the courage to break up with her, so turns her in to the FBI for hacking access to the elevators at the Freedom Tower in New York City. Bryce gets a deal for a tell-all book about Belson who decides to leave Palo Alto, leaving Richard with ownership of the decentralized internet patent but no funding.

Silicon Valley S4, Episode 6: "Customer Service"

May 28, 2017
After a disturbing encounter with Hanneman, who urinates into Erlich's Corvette, Richard abandons searching for investors and tries to pre-sell cloud storage from their projected service. After several meetings fail because Belson left, they extort an insurance company FGI's CTO, Dan Melcher, the former TechCrunch judge Bachman twice cuckolded, to approve them. However, reviewing the tech late into the night, Hendricks ends up having sex with Melcher's new fiancée. Meanwhile, testing a prototype app, Dinesh and Gilfoyle's personal data is swapped onto each other's phones, leading to a tense standoff. While trying to prove he is still relevant, Erlich inadvertently crashes a meeting with Keenan Feldspar, an up-and-coming VR wiz, and brings him to Laurie and Monica's new firm, Bream-Hall, as leverage to get a job.

Silicon Valley S4, Episode 7: "The Patent Troll"

June 4, 2017
Pied Piper's space saver app reaches the top 500 utility apps on the Hooli store. This makes them a target for elderly lawyer Stewart Burke who lives off royalties; he bought patents from a failed startup and is working his way up the list seeking settlements. Feeling they are being shaken-down, Richard rallies the next targets on the list to join together, but they turn on him and, with a stronger case from those settlements, Burke raises his demand from $20,000 to $300,000. Hendricks turns the tables by threatening Burke's copyright claims to gain a perpetual license. Bachman returns half of his finder's-fee for Feldspar for a salaried position at Bream-Hall. To network with his rivals, he accepts an invitation to a basketball game not realizing he is expected to play; he breaks his leg while trying to install a practice hoop. Gilfoyle uses Anton to hack Jian-Yang's annoying smart fridge.

Silicon Valley S4, Episode 8: "The Keenan Vortex"

June 11, 2017
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.

Silicon Valley S4, Episode 9: "Hooli-Con"

June 18, 2017
Needing 123,000 new users, the team head to Hooli-Con, following Mia's advice to disguise their app as a Hooli download for free Wi-Fi at the event. Dinesh and Gilfoyle strategically place routers for maximum interception coverage; Hoover, Hooli's head of security, is suspicious and warns Barker who rebukes him for the distraction. Richard sabotages the screen saver of Winnie's new boyfriend, who reports it and triggers a response team which discovers some of the routers. The Pied Piper team attempt a workaround but are caught, and Jared is outraged at Richard for risking everything on something so petty. Hoover confronts them with CCTV evidence but lets them go as Richard once helped Belson hinder Barker's plans at Hooli. Pied Piper gains sufficient installs. However, Barker and Feldspar's keynote is a mobile demo of HooliVR, which causes a number of phones in the auditorium to explode. Meanwhile, Erlich deciding that he and Richard are forever cursed, decides to move to Tibet on Gavin Belson's invitation. When he gets there, Gavin is far from happy to see him.

Silicon Valley S4, Episode 10: "Server Error"Mike Judge

June 25, 2017
Gilfoyle confirms that fifty exploded phones had Pied Piper's app. Instead of a firmware update, Barker intends to replace 9 million smartphones in three days, at great expense. He tries to triple production with a motivational speech in China and is taken hostage by factory workers. Belson finds out and decides leave Tibet and go to China to try to get his company back. He invites Erlich, but Erlich is lazy and wants to smoke opium in his den. Gavin then gives his innkeeper enough money to house Erlich for five years and leaves Erlich in the Tibet den. Belson negotiates Barker's release, regaining the board's trust and his position as CEO. Meanwhile, during an attempt to move Pied Piper's network to their server, Anton, the incubator's broadband is cut for unpaid bills. Richard tries to move Anton to Stanford, but the server components fall out of the truck en route. They are surprised to find their network is still running all of FGI's data. Anton backed itself up to Jian-Yang's smart refrigerator, which Gilfoyle hacked with Pied Piper's code, and the code spread to other refrigerators creating a distributed network and proving their concept. Pied Piper agrees to funding from Bream-Hall.
