String Bio is a technology company.
String Bio develops and manufactures sustainable ingredients using a proprietary gas fermentation platform. The company applies synthetic biology, chemistry, and process engineering to convert methane, a greenhouse gas, into high-quality proteins and other value-added products. This approach offers alternatives for various industries, aiming to reduce environmental impact and meet market demands.
String Bio was co-founded in 2012 by Ezhil Subbian and Vinod Ml Kumar. Their insight focused on biology's potential to transform methane into useful materials, leading to their innovative platform. The company's vision was conceived in Silicon Valley before establishing operations in Bengaluru, India, to commercialize its biotechnological solutions.
String Bio's offerings serve diverse sectors, supplying ingredients for animal nutrition, human dietary applications, and agriculture. The company's mission is to redefine manufacturing with sustainable processes that manage natural resources. Its long-term vision focuses on fostering a cleaner, resource-efficient global economy through biological innovation to produce essential products.

String Bio is a Bengaluru-based biotechnology company founded in 2012 or 2013 that develops sustainable products through its proprietary String Integrated Methane Platform (SIMP), a gas fermentation technology converting methane—a potent greenhouse gas from waste or natural sources—into high-value ingredients like single-cell proteins, lactic acid, succinic acid, and food additives.[1][2][3][4][6][7] It serves sectors including animal nutrition, human nutrition, agriculture, and personal care, solving critical problems such as climate change, food security, and reliance on unsustainable resources like soy or fishmeal by producing climate-positive, performance-differentiated alternatives that improve feed efficiency and reduce carbon footprints.[1][2][4][7] The company has scaled from lab to commercial production, backed by a strong IP portfolio with granted patents in the US, India, and Europe, and endorsements from industry leaders like Dr. Kiran Mazumdar-Shaw of Biocon.[1][3]
String Bio emerged from a "radical idea" to harness biology for complex environmental challenges, founded by Ezhil Subbian and Vinod Kumar in Bengaluru, India, with founding dates cited as 2012 or 2013.[1][2][4] The founders drew on interdisciplinary expertise in synthetic biology, chemistry, process engineering, and fermentation, inspired by nature's simple solutions like longstanding fermentation processes to address methane's greenhouse impact.[1][5] Early pivotal moments included developing SIMP to convert methane into proteins for animal feed, achieving lab-to-pilot-to-commercial scale-up over years, and securing initial traction through customer validation in nutrition and agriculture.[1][2] The team's "motley crew of innovators" has since expanded, focusing on commercialization while earning awards like Future Food Asia and BIRAC Innovator.[5][7]
String Bio stands out in the biotech space through these key strengths:
String Bio rides the circular economy and sustainability wave, capitalizing on rising demand for climate-positive solutions amid global methane reduction pledges and protein shortages driven by population growth and climate pressures.[2][3][7] Its timing aligns with advances in synthetic biology and fermentation, turning waste methane—a key contributor to atmospheric warming—into valuable chains, supporting UN sustainability goals and influencing agribusiness toward greener feedstocks.[1][3][4] By disrupting soy/fishmeal markets and enabling bio-polymers, it fosters ecosystem-wide shifts: competitors like DSM and Avantium signal a maturing field, while String Bio's India-based innovation exports deep tech globally, amplifying impact in emerging markets and drawing investment into gas-to-product biomanufacturing.[3][7]
String Bio is poised for accelerated growth by expanding SIMP-derived products into human nutrition and bio-materials, leveraging its scaled platform and IP to capture shares in the $500B+ animal feed and protein markets while advancing climate goals.[2][3] Trends like methane capture mandates, precision fermentation hype, and sustainable investing will propel it, potentially through partnerships or acquisitions akin to peers like Calysta.[3][7] Its influence may evolve from niche innovator to ecosystem shaper, commercializing "next-generation ingredients" that balance food security with planetary health—transforming that initial radical idea into a cornerstone of biotech sustainability.[1][5]
