Startup snaps up Benson Hill's sustainable soy assets

Biotechnology Feed ingredients Mergers and acquisitions +3 more

The assets of Benson Hill, a developer of more sustainable soy varieties that were incorporated into some of BioMar’s aquafeeds, have been bought by Confluence Genetics.

Incorporating these into aquafeeds could help to reduce the environmental footprint of aquafeed producers and their customers

Benson Hill, which used genetic selection and gene editing to produce a range of soy varieties, filed for bankruptcy earlier this year.

According to the US company, ultra-high protein (UHP) and low anti-nutrient levels in their soy reduce the need for processing steps to concentrate protein levels. The result is a minimally processed ingredient designed as an alternative to commodity soy protein concentrate (SPC) that requires up to 70 percent less water and up to 50 percent less carbon dioxide equivalent to produce than US-sourced SPC.

The deal follows the acquisition of Confluence Genetics by a group of seasoned agribusiness investors, spearheaded by Expedition Ag Partners and S2G Investments. The company says it will focus on scaling its proprietary ultra-high protein soybean genetics for animal feed, expanding market position in its specialty food grade portfolio, and expanding geographies by leveraging its unique soy germplasm, AI-powered breeding platform, and speed breeding facility.

“This is more than a financial reset - it’s a strategic reboot and a bright beginning,” said Kim Hurst, Confluence Genetics’ newly appointed chief executive officer, in a press release. “With our proprietary genetics, CropOS technology platform, and state-of-the-art speed breeding facility, we will deliver high-value, differentiated, quality trait soybeans.”

Confluence Genetics’ acquisition includes more than 350 patents issued or pending, and its 2029 soybean class – recently planted in 2025 field trials – is expected to deliver advanced quality traits in the industry. This lineup of value-added varieties is designed to deliver higher protein, boost oil quality and offer differentiated genetic advancements across the agriculture value chain.

Expedition Ag Partners president and CEO, Mike DeCamp, who is also the incoming board executive chairman for Confluence Genetics, emphasised that the company's future is built upon valuable lessons learned from past experiences and possesses significant growth potential.

“Confluence Genetics has the right tools, talent, and technology to shape soy innovation in ways that we’re only beginning to appreciate,” said DeCamp. “We at Expedition Ag believe Confluence Genetics has a promising future as a nimble innovation engine that will deliver value across the value chain, from farm gate to end user. Our team is thrilled to support Confluence Genetics as it combines the ambitious spirit of a startup with the disciplined approach of a category leader.”

Under Hurst’s leadership, Confluence Genetics will be headquartered in Creve Coeur, Missouri, which is also the location of its indoor speed breeding facility, and will operate with an experienced team of approximately 60 employees.
