§ Private Profile · Somerville, MA, USA
Developer of sustainable biological nitrogen fertilizers for agriculture, using engineered microbes to enhance soil health.
Kula Bio, based in Boston, Massachusetts, USA, develops sustainable biological nitrogen fertilizers using engineered microbes, such as Xanthobacter autotrophicus, to replace synthetic fertilizers derived from the Haber-Bosch process. Its flagship product, Kula-N, provides a slow-release nitrogen source designed to enhance soil health and significantly reduce greenhouse gas emissions in agriculture. The company secured $50 million in Series A funding in 2022, with notable investors including AgFunder and LowerCarbon, to scale operations and expand product trials for crops like lettuce and corn. This technology originated from over a decade of research by Harvard professor Dan Nocera. Kula Bio targets organic and sustainable farming markets, offering a premium alternative to conventional nitrogen inputs. The organization was founded in 2018 by Bill Brady and Kelsey Sakimoto.

Kula Bio is a Boston-based agricultural technology company founded in 2018 that develops sustainable nitrogen fertilizers using supercharged nitrogen-fixing microbes, specifically *Xanthobacter autotrophicus*, to replace synthetic nitrogen and reduce environmental impacts.[1][2][4][5] The company serves farmers across organic and conventional crops by delivering plant-available nitrogen directly at the root zone, enabling up to 20-25% replacement of traditional fertilizers without yield loss, while cutting greenhouse gas emissions by up to 84% per kilogram compared to conventional options.[5][7] This addresses key problems like nitrogen runoff, fossil fuel dependency in the Haber-Bosch process, and soil degradation, with products like Kula-N for organic use and Kula-Next for conventional farming showing consistent results in trials across crops, soils, and conditions.[1][4][5][8] Backed by $50 million in Series A funding, Kula Bio demonstrates strong growth through on-farm trials since 2019 and a beachhead in the high-margin organic market.[1][5]
Kula Bio emerged from peer-reviewed research in Dr. Dan Nocera’s lab at Harvard University, where his invention of the "bionic leaf"—a system using sunlight, hydrogen, and CO2 with genetically engineered microbes to produce biofuels—inspired the core technology.[2][6] Co-founder and CEO Bill Brady, a seasoned entrepreneur with experience scaling and selling commodity chemicals, led the commercialization effort, spinning out the tech to create energy-storing bioplastics that "supercharge" microbes for prolonged nitrogen fixation in soil.[1][6] Founded in 2018 and headquartered in Boston, the company quickly raised $50 million in Series A funding and began proof-of-concept trials in 2019 with third-party cooperators, evolving from lab innovation to field-tested solutions amid rising demand for sustainable agtech.[5][6]
Kula Bio rides the wave of regenerative agriculture and climate tech, targeting the $200+ billion global nitrogen fertilizer market dominated by energy-intensive synthetic production responsible for ~2% of global emissions.[1][7] Timing aligns with regulatory pressures on fertilizer runoff (e.g., EU nitrate directives), farmer incentives for carbon sequestration, and the shift to biologicals amid soil health crises. Market forces like rising natural gas costs for Haber-Bosch and premium pricing for organics favor Kula's low-volume, low-emission model, which sequesters carbon in soil while enhancing biodiversity.[1][5][6] By disrupting the "factory-to-field" model and enabling affordable stewardship, Kula influences the ecosystem, partnering with investors like AgFunder and proving biologicals can scale reliably, potentially accelerating adoption in row crops and turf.[1][2][5]
Kula Bio is poised to expand from its organic beachhead into broader conventional markets, with planned multi-year trials (e.g., 3-year study in Salinas, CA starting 2024) validating long-term soil benefits and yield gains.[1][5] Trends like AI-driven precision ag, policy-driven emission cuts, and investor focus on food security will propel growth, potentially capturing share as biologicals mature. Influence may evolve through platform extensions—maximizing microbial properties for other nutrients or turf—redefining nitrogen as a distributed, solar-powered factory in every field, bridging profitability and planetary health from day one.[2][4][7]
