SeaWith is solving environmental problems of the world in ways no one has thought nor attempted ever by using resources from the ocean.
The initiation of SeaWith was Yo.od to develop iodine reduction technology on seaweed without affecting the integrity and taste of seaweed. The success of Yo.od development was the seed of the SeaWith, which is adding value to marine resources with bioengineering. It will lead the world one step closer to a more sustainable future.
Yo.od evolved into SeaWith to secure a sustainable food sources for humanity. We are developing delicious and clean meat, Well-done (project name : Cmeat), without slaughter by using the abundant marine resources, seaweed.
The meat without slaughter for rights of all living is the goal that SeaWith is getting a step closer to make it possible each day.

The APAC Society for Cellular Agriculture (APAC-SCA) announced its launch this week as a new coalition with a mission to offer member companies developing cultivated meat and seafood access to shared information. Its key priorities include interacting with consumers, building knowledge and acceptance and developing straightforward regulatory frameworks.
In a joint statement by APAC-SCA’s management committee, which include founders from some of the region’s most established cultivated players such as Dr. Sandhya Sriram (President) of Shiok Meats; Mr. Ziliang Yang (Secretary) of CellX; Dr. Jay Hyeongun Jee (Treasurer) of DanaGreen; Mr. Gary Brenner, Director of Market and Corporate Development at Aleph Farms; and Ms. Carrie Chan, CEO and Co-founder of Avant Meats said: “We’re delighted to announce the launch of the APAC Society for Cellular Agriculture; we hope the society and our coalition will foster a productive and harmonized industry in APAC.”

A shared vision
The 11 founding members include Singapore’s Shiok Meats and Gaia Foods, Israel’s Aleph Farms, SuperMeat and MeaTech, Hong Kong’s Avant Meats, China’s CellX and Joes Future Food, South Korea’s DaNAgreen and SeaWith, and Japan’s IntegriCulture.
All of the 11 companies signed up to the society share one common vision: cultivated meat and seafood products as a key solution to numerous issues that plague the global food supply chain, as well as to guarantee food security, human health, sustainability and animal welfare. APAC-SCA hopes to be a ‘kick-start’ for the entire sector, bringing harmonised values and goals together for mutual benefit and industry progression.
“As a society, we wish to engage with all the stakeholders in the region to promote transparency, safety, and awareness. We stand behind the vision of a more sustainable, healthy, and food-secure planet for all, and hope to build long-lasting partnerships with key industry, community, public, and governmental entities in efforts of promoting a brighter future.”

Initial focus points
While each individual member company is working on reaching its own milestones, all share one important common goal: bringing cultivated products to market.
As such, APAC-SCA’s priorities will include connecting with key policymakers within the regulatory sphere, to offer education and access to developments. From there, industry think tanks will prove invaluable, especially when looking to connect with consumers. One of the biggest stumbling blocks for the cultivated meat and seafood sectors, aside from gaining approvals for commercial sale, is public acceptance. The APAC-SCA will work to drive consumer awareness and understanding about the benefits and safety of cellular agriculture.
The need for representation
The APAC-SCA’s announcement comes on the heels of the Good Food Institute (GFI) APAC’s recently released its 2021 investment report, which revealed that last year was a record year for the alt-protein sector in the region, with increases across the board for all verticals. Most pertinently, cultivated meat and seafood claimed more funding than ever before” $62 million, up from $44 million in 2020, was recorded, demonstrating significant growth. One of the key reasons is that Singapore has established its spot on the global map as a leading city when it comes to alternative protein innovation. The nation-state remains the only country globally that has allowed for cultivated meat to be sold commercially, with Eat Just’s GOOD Meat chicken available at various F&B spots, including hawker stalls.
New APAC Cellular Agriculture Coalition Aims To ‘Foster A Harmonized Industry’ Ahead Of Commercialization

South Korean cultivated meat start-up SeaWith has developed a way to produce scaffolding and non-FBS growth media at a much lower cost using microalgae.
When they co-founded SeaWith in 2019, Joonho Keum's and Heejae Lee's idea was to produce low-iodine kelp. Soon enough, however, they realised they had the right technology and in-house talent to produce growth media and scaffolding for other cultivated meat start-ups, and also to develop their own cultivated steak.
Flash forward two years: SeaWith's ambition is now to present its first cultivated meat product to consumers by 2022 and accelerate commercialisation of cultivated meat with low-cost sustainable materials.
In this interview, Heejae Lee talks about SeaWith’s technology and future plans.
Q: How do you produce your low-iodine seaweed? What's the technology behind it?Brown-algae seaweeds, commonly called kelps, are well-known for accumulating great amounts of iodine and then releasing it when damaged by oxidative stress. We use this principle to induce the algae to naturally lower their iodine content by releasing it in the atmosphere. This process was documented in Proceedings of the National Academy of Sciences of the United States of America, a peer-reviewed multidisciplinary scientific journal.
Q: SeaWith was founded just two years ago: was cultured meat always part of the plan? We started as a producer of low-iodine seaweed and then pivoted to cultured meat after a month. Because all of five co-founders majored in biology or bio-engineering, we wanted to apply our technology to algae to make an even bigger impact on the alternative protein market.
Q: Can your growth media and scaffolding be used for other types of meat too?Yes. We are planning to test cell types for different animals, such as pig, chicken, and fish.
Q: Are you planning to sell your culture media and scaffolding to other companies too?Supplying our culture media and scaffolding to other cultured meat companies is our main strategy. Our goal is to help cultured meat companies speed up time to commercialization of cultured meat by reducing production costs. Our scaffold and culture media is extremely cheap, so it could be an optimal base material for cultured meat.
Q: What type of cultivated meat product are you targeting?Our first product will be beef steak. Our scaffold ‘ACe-gel’ can help the attachment of muscle cells and differentiation by alignment, and supply the nutrient, oxygen deep inside the tissues. We already developed >1cm-thick “cuts” of meat and held a tasting event this past May.
Q: How receptive are South Korean consumers to cultivated meat?They’re actually quite open to it. I was surprised because I worried that people might see microalgae as an ‘unnatural’ material for cultivated meat. As it turned out, however, seaweed is recognized as safe and healthy. Korean consumers set a high value on price because Korean beef (called “Hanwoo”) is much more expensive than in the US or other countries. Taste and safety are also important.
Q: Will cultivated meat be approved soon in South Korea?Korea’s FDA (The Ministry of Food and Drug Safety) is still working to create guidelines for cultivated meat. A draft will be released in November this year. We aim to register our pilot batch scale product as food in the last quarter of 2023. During the process, our materials will be ready as a product.
SeaWith Cracked the Code of Low-Cost Non-FBS Growth Media and Scaffolding With Microalgae

South Korean food tech Seawith has set its sights on churning cell-based steak out to the masses for cheap. By the end of the decade, the company wants to produce cultured steak for costs as low as $3 per kilogram. It comes on the heels of revealing its plan to debut its first cell-based meat products to consumers at a pilot restaurant before the end of 2022.
Seawith, a South Korean cell-based meat startup, has made an ambitious target of producing cultured steak for as little as $3 per kilogram by 2030. The goal was revealed by the company’s co-founder and CTO Heejae Lee in a recent interviewwith FoodNavigator-Asia, where Lee also shared how its proprietary cell-culture technology that uses algae will be critical to bringing costs down.
Lee started Seawith with co-founder Joonho Keum two years ago, when the two came together during their PhD studies at the Daegu Gyeongbuk Institute of Science and Technology (DGIST).
$3 per kilogram by 2030
In the interview, Lee explained that the most expensive part of producing their cell-based meat is the remaining 10% of traditional cell culture media the company still relies on. So far, Seawith has managed to replace 90% with their own seaweed-based culture media and scaffolding. Seawith team. (Image: Seawith)
Using algae, which is regionally abundant, is not only cost-efficient but also tackles the ethical issues associated with the use of fetal bovine serum (FBS), which is not slaughter-free as it is harvested from bovine fetuses.
“The scaffolding we have developed is based on seaweed, so as to hold the bovine cells that will grow into the steak as well as allow nutrients to penetrate deeper into the resulting tissue culture, which can make cultured meat cuts thicker than 1cm,” said Lee. “We have also developed our own culture media from microalgae – this holds the benefits of algae nutrition in addition to being much cheaper as microalgae is abundant.”
“By 2030, we aim to make 1 kilogram of meat for less than US$3 per kilogram – this is definitely doable once we get the technology right.”

In terms of its commercialisation plans, Seawith says that their domestic market in South Korea will be their first target. Earlier this year, the company revealed that it wants to be able to debut their first cell-based meats to diners at a pilot restaurant by the end of 2022. It will have to overcome regulatory hurdles to then launch commercially on the market, most likely through high-end restaurant foodservice.
To accelerate its go-to-market strategy, Lee says the startup is currently raising fresh funds, which will go towards scaling up its production capacity and expediting regulations and food safety tests.
“Seawith will be closing our Series A funding next month, and we estimate the funds to come in at around US$7 million,” he said. “We have two main plans…to obtain a bigger bioreactor for mass production to reach the industrialization stage more quickly, and also to help with all the necessary registrations, [such as] a HACCP-grade facility and biosafety certifications with the FDA.”
But Seawith is also eyeing Singapore and the U.S. as potential initial launch pads, pending the speed of regulations in South Korea. Singapore is building up its reputation as the region’s food tech innovation hub, famous for being the first to have approved the sale of cultured meat and home to cell-based players like Shiok Meats and Avant Meats, a Hong Kong company that has chosen to also establish a base in the city.

Seawith To Make Cell-Based Steak At $3 Per Kilogram By This Decade

It’s been a banner year so far for cultured meat. In addition to all of the funding that’s been flowing into the space since the start of 2021, there is also a growing number of startups from around the world attacking the issues of creating cell-based meat in unique ways.
The latest such startup to come to our attention is South Korea’s Seawith, which is leveraging algae to differentiate itself from other cultured meat players. The company uses algae to replace the fetal bovine serum (FBS) that has historically been used as a growth medium for cells. FBS is expensive and controversial, so most cell-based meat startups we cover are developing technologies that don’t require it. But Seawith is also using algae as a scaffolding to grow meat, which the company says yields thicker “cuts” of meat.
Following is a brief Q&A conducted via email with Heejae Lee, CTO of Seawith, who provides a little more insight into the company and what it is creating. Answers have been lightly edited for clarity.
1.) What makes Seawith different from other cell-based meat companies?
Seawith has the distinction of making the world’s first perfect steak at a price similar to slaughter meat. Based on algae engineering technology, it has replaced most of the bovine serum, which accounts for more than 90 percent of the cost of culturing meat, and the cell culture scaffold technology can make cultured meat thicker than 1cm.
2.) What makes algae so useful in creating cell-based meat?
The key principle of cultured meat is that one muscle cell takes nutrients and synthesizes them to make large meat. Algae is rich enough to be used as a nutritional supplement, which allows efficient cell culture by supplying it to cells. Also, algae are one of the most abundant resources on Earth, and they have the advantage of being cheap and available everywhere because they can grow anywhere with water and sunlight.
3.) Where are you at with your product right now?
We just finished our research and held a cultured meat tasting event. Cultured meat made with Korean bovine cells was evaluated well by attendees, who said it had the taste and aroma of beef, and the texture of meat could be seen. Currently, it is a muscle-only culture, but we are preparing various features such as taste of fat cells. We are preparing to get permission to produce enough to supply large quantities of products to restaurants by 2023.
4.) What types of cell-based meat will you be creating?
Seawith is making beef steak. There are many different types of meat, but the reason why we are makingdifficult steaks is that only the technology we have can implement them. After perfecting the texture of muscle tissue, we plan to develop various meat products such as chicken, pig, and fish as well as meat products and animal feed.
5.) What is your timeline to bring your product to market?
We are currently discussing with the Ministry of Food and Drug Safety to make a trial sale in Korea with the aim oflaunching a restaurant at the end of 2022. To this end, we are planning an urban cultured meat factory and will introduce a minimum production model by 2021. From 2023, we are preparing for local tasting event and product launch in different locations such as North America and Singapore.
South Korea: Seawith Uses Algae for Serum and Scaffolding in Cultured Meat

South Korean startup SeaWith has set its sights on bringing cultured meat to diners by the end of next year. The firm has already developed its own seaweed-based cell culturing medium and scaffolds, and is now in the process of scaling up production ahead of its plan to unveil its final cultivated meat products at a pilot restaurant.
Founded two years ago by Joonho Keum and Heejae Lee, who came together during their PhD studies at the Daegu Gyeongbuk Institute of Science and Technology (DGIST), SeaWith is a homegrown South Korean food tech with ambitious plans to revolutionise the country’s protein production.
While South Korea’s plant-based meat industry is steadily growing, with big players like Pulmuone entering into the space alongside vegan startup brands like Unlimeat, SeaWith wants to make real animal meat – but without the animals. At their base in the metropolitan city of Daegu, the company is using cellular agriculture to culture slaughter-free steaks that will hopefully convince even the hardiest meat-lovers to turn away from its conventionally farmed counterparts.
By doing so, SeaWith hopes to disrupt the livestock industry and its enormous environmental footprint, from the huge amounts of greenhouse gas emissions it releases, to the overuse of crucial planetary resources like land and water.
But one problem standing in the way for SeaWith and the rest of the cultivated protein industry when it comes to mass consumer adoption is cost – and currently, culturing meat is an expensive process.
To tackle production costs, SeaWith has been working on developing their own materials that are necessary for cell-based meat production – cells, scaffolds and culturing media. And they’ve managed to do it using the regionally abundant and cost-efficient seaweed, which offers an additional benefit of being completely plant-based and cruelty-free, as opposed to the existing expensive and non-animal-free use of fetal bovine serum (FBS).
According to the firm, their microalgae-based cell-culture medium is already able to replace more than 80% of FBS usage at current levels. Already inexpensive to produce, the startup says that they are likely going to keep cutting costs even further as they scale mass production of their microalgae materials.
Once the cells are feed nutrients to begin growing in the media, SeaWith gives cells their own algae-based 3D scaffold dubbed “Ace-Gel” to allow the cells to begin multiplying, growing and forming a thick tissue structure. After incubating the cells with the scaffolding, SeaWith says they are able to produce a cultured meat prototype that mimics the thickness and texture of a cut of steak.
Their technology has already won them ₩500 million (approx. US$450,000) from South Korean early-stage tech startup investors Bluepoint Partners and Enlight Ventures, and has been handpicked to join the country’s government-backed Tech Incubator Program for Startups (TIPS).
While the startup’s cultivated meat product is still in R&D stage, the team has already set an ambitious timeline for commercialisation. By the end of 2022, SeaWith hopes to have scaled their technology and manufacturing capabilities to be able to present their first cell-based meats to consumers at a pilot restaurant, ahead of a commercial launch if they manage to climb over regulatory hurdles.
If they manage to do so, SeaWith could be among the first in the country to launch a cultivated protein product to diners. So far, only San Francisco-based Eat Just has managed to gain regulatory approval from Singapore authorities to sell their cultured chicken on the market in a world’s first in December 2020.
Other homegrown food techs in the running in South Korea include CellMEAT, who recently closed ₩5 billion (approx. US$4.5 million) in a pre-Series A funding round, which will go towards developing its FBS-free cultured meat and lowering costs.
DaNAgreen, who has adapted its initial biomedical scaffolding for cell-based meat production and at a price “a thousand times cheaper than the original”, says that they are now in the process of creating an entire platform for cellular agriculture protein production, from culture media to bioreactors.
