Switch Bioworks

What Switch Bioworks does

Switch Bioworks is a synthetic biology company developing engineered microbial nitrogen fertilizer as a direct substitute for synthetic nitrogen fertilizer. Founded in 2022 in San Carlos, California by Tim Schnabel based on his Stanford PhD thesis on engineering ammonia production in free-living diazotrophs, the company reprograms naturally occurring soil microbes using proprietary genetic "switch" control systems that activate nitrogen production only on plant roots. Its core product is a powder-formulated microbial biofertilizer applied by farmers at sowing through a four-step process (produce, apply, grow, feed); the microbes proliferate alongside germinating crops and switch on nitrogen fixation in situ. Target customers are U.S. Midwest corn growers, with stated plans to scale across additional cereal crops domestically and internationally after successful field trials and full regulatory approvals.

The business model is product-based and B2B to agriculture: Switch Bioworks intends to sell microbial fertilizer formulations to farmers as a replacement for synthetic nitrogen fertilizer, addressing a market where fertilizer represents approximately one-third of crop input costs, accounts for over a gigaton of CO2 equivalent emissions annually, and exhibits significant supply chain and geopolitical risk. The company is pre-revenue and currently in field trial stage, having received first-in-class regulatory authorizations from the USDA and EPA in 2026 to conduct multi-site trials across the U.S. Midwest. Pricing is not publicly disclosed.

The company has raised approximately $27.1 million in cumulative funding, including a $17 million seed round in September 2024 led by Change Capital Partners with participation from Acre, Ag Ventures Alliance, Anthos, Astanor, Emerson Collective, Grantham, and Thia Ventures, supplemented by a $2 million ARPA-E TEOSYNTE grant from the U.S. Department of Energy in January 2025. Headcount stands at approximately 25 employees, predominantly scientists and bioengineers, with senior leadership supplemented by advisors from Syngenta, Corteva, PotashCorp, Indigo Ag, McKinsey, and Stanford faculty. The company holds patents pending on its founder's thesis work, with one featured on the cover of ACS Synthetic Biology.

Core offering

Switch Bioworks engineers naturally occurring symbiotic microbes to produce nitrogen fertilizer directly on plant roots, replacing synthetic nitrogen fertilizer. The product is a powder-formulated microbial biofertilizer (Living Fertilizer) that farmers rehydrate and apply at crop sowing; microbes colonize roots, proliferate alongside germinating plants, and switch on nitrogen production through proprietary genetic control systems.

Product overview

Switch Bioworks operates as a single-product company offering a living fertilizer solution. The core product is a microbial nitrogen biofertilizer consisting of engineered naturally occurring microbes that produce fertilizer directly on plant roots. The microbes are produced, formulated into a powder, and applied by farmers at crop sowing through a rehydration process. The four-step process involves: Produce (microbes in powder form), Apply (rehydration at sowing), Grow (microbial proliferation alongside plants), and Feed (activation of nitrogen fertilizer production via proprietary mechanism). The company is focused on scaling this technology across the U.S. and internationally, with current field trials targeting corn production in the U.S. Midwest.

Products and services

• Microbial Nitrogen Biofertilizer (Living Fertilizer) Engineered, naturally occurring microbes formulated into a powder (billions of dormant microbes per ounce) that farmers rehydrate and apply at crop sowing. The microbes colonize plant roots, proliferate alongside germinating plants, and switch on nitrogen fertilizer production via proprietary synthetic biology control systems, replacing synthetic nitrogen fertilizer inputs for corn and other cereal crops.

Direct peers

• Pivot Bio: Closest direct competitor — commercializes engineered nitrogen-fixing microbial products (Proven G3, ProveN, Return) for corn and other cereal crops. Targets the same U.S. Midwest customer base and same problem (replacing synthetic nitrogen fertilizer) with very similar science.
• Indigo Ag: Major microbial agriculture company that has launched 20+ microbial products planted on tens of millions of acres globally (per Switch Bioworks' CBO Brett Boghigian's prior tenure). Competes head-to-head for shelf space with biological nitrogen-fixing products and adjacent biological inputs.
• Sound Agriculture: Develops microbial and chemistry-based nitrogen efficiency products for row crops including corn. Targets the same farmer pain point of reducing synthetic nitrogen use with a sustainability- and yield-driven go-to-market.
• NewLeaf Symbiotics: Microbial agricultural company focused on pink pigmented facultative methylotrophs (PPFMs) for crop nutrition and stress tolerance. Competes in the same biological-input category with a different microbial chassis and platform.

Emerging players

• AgBiome: Ag-input biologicals company combining microbial crop protection with biological nutrition. Uses a microbial discovery platform to develop products targeting similar ag-input customers, though focus is broader than just nitrogen fixation.
• Joyn Bio (Ginkgo Bioworks / Bayer joint venture): Was a direct synthetic-biology nitrogen-fixing microbial venture backed by Bayer and Ginkgo Bioworks. Highly relevant as the closest analogue to Switch's engineered microbe approach, though its dissolution/transition makes its competitive weight uneven.

Broad incumbents

• Ginkgo Bioworks: Cell engineering and synthetic biology platform that has invested in ag-biologicals and historically partnered on nitrogen-fixing microbes (Joyn Bio). Operates as a broad incumbent in the synthetic biology tooling layer relevant to Switch's technology stack.
• Codexis: Industrial biotechnology / enzyme engineering company applying directed evolution to sustainable chemistry, including ag-input applications. Comparable as a public, mature synthetic biology company with Switch's CTO Steve del Cardayre as a former employee.
• Corteva Agriscience: Major global seed and crop protection company with a growing biologicals portfolio and a former CTO (Neal Gutterson) now advising Switch. Represents both a potential partner and a competitive incumbent in microbial ag-inputs.
• Syngenta: Global ag-input giant with an expanding biologicals platform built in part through acquisitions and corporate development led by Switch advisor Eric Bartels. Comparable as a large incumbent pursuing the same biological-fertilizer category.
