Robot kills fish instantly, aims to cut waste

Poseidon robot – At TechCrunch’s StrictlyVC event in Los Angeles, Shinkei Systems’ founder Saif Khawaja pitched Poseidon—a refrigerator-sized robot for boats that uses computer vision to locate a fish’s brain and sever gills—framing the move as a way to reduce stress and spoil

On a boat, the moment matters. Shinkei Systems’ Poseidon robot doesn’t wait for the usual dockside scramble. It scans each fish with computer vision, identifies the species, locates the brain, then pierces the brain and severs the gills so the fish dies before it can thrash or suffocate.

The question driving the pitch wasn’t what venture investors usually circle around. At TechCrunch’s newest StrictlyVC event in Los Angeles, the conversation repeatedly returned to something that doesn’t come up often in a room full of technology bets: how do you know if a fish is stressed out?

For Saif Khawaja, that’s the whole premise. Shinkei’s approach is essentially an automated. industrial-scale version of ike jime. a centuries-old Japanese technique traditionally performed dockside by trained fishermen at the moment of catch. The goal is to kill instantly and drain blood so decomposition is delayed long enough for flesh to be safely aged for days—sometimes longer—before it’s served.

Khawaja described the alternative in practical terms: a slow death over a few minutes to an hour can flood fish with stress hormones and lactic acid. That, he says, dulls flavor and shortens shelf life. The company links the payoff to how sushi and sashimi get their depth. Ike jime delays decomposition. then aging lets enzymes slowly break down muscle—part of what gives top-tier sashimi its concentrated. umami-heavy flavor.

But the story isn’t just about killing. Shinkei says it has expanded into a vertically integrated fish harvester and processor, deploying robotics and AI across the chain from boat to plate.

In the model Khawaja laid out for attendees in El Segundo. Shinkei installs Poseidon by giving the machines to fishermen for free. The company then pays a premium price for the fish that come out of them—well above what the catch would fetch at a standard dock auction. In exchange, Shinkei takes full possession of the fish rather than letting fishermen sell it on the open market. The catch then ships to a 16. 000-square-foot plant Shinkei bought in Tacoma. Washington. where it’s broken down and sold under Shinkei’s consumer brand. Seremoni. marketed as “ceremony grade” fish.

If you want the most visible proof point so far, it’s already on a menu. Erewhon. the Los Angeles grocery chain beloved by influencers. sells Shinkei’s fish as Seremoni Grade Miso Black Cod hot off the prepared-foods bar. The marketing leans on framing that the fish are “sustainably caught. humanely harvested.” For now. the arrangement is a pilot running out of Erewhon’s Manhattan Beach location. Wider rollout to other stores is contingent on how well the pilot sells.

Khawaja also told the crowd that Shinkei already supplies fish to restaurants holding a combined 50 Michelin stars. He added a claim that he said has reportedly never happened before: Japan importing American-caught fish into its own fish markets. which have historically treated American seafood as distinctly inferior to the domestic product.

Even Khawaja, though, treats the animal-welfare story as secondary to what he calls the practical selling point—quality. A catch that might normally have a 5-to-7-day shelf life can stretch to 12 or 14 days, he said. He also said the company has cooked fish three weeks after it came out of the water with no issue.

That quality argument is backed by Shinkei’s newest product: an in-plant sensor system designed to quantify shelf life by scanning fish and projecting an individual shelf life for each one. In a business where spoilage is often invisible until it isn’t. Khawaja estimated that roughly 18% of product is lost to spoilage just between dock and store—before retail loss is even counted.

Spoilage also sits on top of a supply-chain detail that surprised many people watching from the outside. Shinkei’s pitch didn’t shy away from it: a meaningful share of fish caught in U.S. waters by U.S. boats gets frozen and shipped overseas—often to China—for labor-intensive work like heading. gutting. scaling. and filleting—then shipped back to be sold in the U.S.

Industry estimates of how much American seafood is imported run as high as 90%. though roughly half of that. by some estimates. actually originated in domestic waters before making the round trip abroad. Reporting has tied parts of China’s seafood processing sector to forced labor. including Uyghur workers in Shandong province and North Korean labor in Liaoning. making the system a target of U.S. trade and labor scrutiny in recent years.

That’s part of why the industry has pushed to “re-shore” some processing. spurred partly by tariffs and pandemic-era disruptions that made the China round trip less attractive. The bet behind Shinkei—and behind the investment from Founders Fund—is that re-shoring the entire chain. catch. kill. process. and distribute. all under one roof in Tacoma. can be done profitably enough to outcompete the loop.

Founders Fund partner Delian Asparouhov framed the gamble in a way that landed with the room: there’s “essentially nobody else on Earth who wants to spend their life on robots that kill fish. ” and given the smell of the Shinkei’s office. he added. it’s no wonder. Attendees laughed at the observation, even as Asparouhov’s point underscored the difficulty of the category itself.

Shinkei is not alone, though. Asparouhov pointed to a Japanese firm called Nichimo that sells a device to stun fish to assist humans performing ike jime by hand. He also referenced several Norwegian startups building robotic systems for more humane fish slaughter and processing. Shinkei’s edge. for now. is being the only one running the fully automated version of the technique at scale on U.S. boats.

He also said the fund tries to avoid crowding in fashionable areas. Asparouhov told attendees that AI and defense together account for something like 15% to 20% of Founders Fund’s deployed capital. well below what he estimated is typical elsewhere in venture. Shinkei sits alongside other bets in food and agriculture: Halter. a New Zealand-founded company making solar-powered. GPS-equipped cattle collars that let ranchers herd cattle remotely; and Ohalo Genetics. the crop-genetics company started by “All-In” podcast co-host David Friedberg.

That appetite for hardware and physical-world businesses has its own receipts. Asparouhov reminded the room that Founders Fund’s headline-grabbing recent win isn’t tied to fish at all. Its early and aggressive bets on Elon Musk’s SpaceX—linked to a relationship tracing back to Peter Thiel and Musk’s shared history at PayPal—are reported to have generated many tens of billions of dollars for the firm.

Asparouhov argued that outcome will accelerate a broader shift in venture toward hardware and physical-world companies. because most of today’s largest companies on the Nasdaq involve complex electromechanical systems rather than pure software. He predicted more of SpaceX’s alumni—flush with liquidity and shaped by working alongside Musk—will go on to start their own ambitious physical-world companies.

Whether Shinkei becomes one of those outcomes will take time. The company has taken on far more than one problem. It’s a robotics manufacturer. a seafood processor. and a consumer brand all at once. each with its own hard edges. Fishermen are used to working a certain way. Distributors are built around decades-old habits. Chefs and grocery buyers still have to be convinced that a story about humane fish slaughter is worth paying more for.

There’s also the matter of the hardware and the product itself. The Poseidon system has to survive saltwater, fish guts, and life on a commercial boat. And since the product is perishable, there’s little tolerance for the kind of stumble a straightforward software company can brush off.

Still. standing in El Segundo. with Khawaja and Asparouhov speaking side by side. the audience seemed to understand why Founders Fund finds the bet compelling. It’s not just that they say Shinkei is novel in a dysfunctional industry. It’s that. in their telling. the country’s venture ecosystem rarely attracts founders willing to spend their lives building robots that kill fish—and then make the quality problem that follows look solvable.
