CHS-GROWMARK Fund Backs OpenTug to Digitalize Grain Barge Logistics

Cooperative Ventures, the joint venture capital fund of CHS Inc. and GROWMARK, has invested an undisclosed sum in OpenTug, a logistics technology company focused on inland and coastal marine transportation — and CHS is already moving to implement the startup's barge management system inside its own supply chain.

The St. Paul, Minnesota-based fund announced the deal without disclosing the investment amount, the stake acquired, or a deployment timeline. Those gaps matter for anyone weighing the announcement's practical weight: this is a capital commitment whose size and measurable impact on freight costs remain unverified.

What does OpenTug actually sell?

OpenTug is the company behind BargeOS, an AI-native software platform for marine logistics. The platform combines several functions in one system:

• commercial planning
• voyage management
• invoice reconciliation and intelligence
• performance management and reporting
• integrated barge GPS monitoring

A feature called BargeOS Autopilot automatically ingests traffic reports and operational emails, giving shippers and carriers what the company describes as a comprehensive, real-time view of barge movements and voyage activity.

The claimed economics for grain shippers are specific in kind, if not in number. OpenTug says the platform reduces costs by cutting idle barge days, improving estimated arrival time accuracy and minimizing demurrage charges — the penalties shippers pay when barges sit loaded past their allotted time. For co-ops moving grain and fertilizer on the Mississippi system and other waterways, demurrage and idle time are direct hits to basis and freight budgets.

What are the partners saying?

Jason Aristides, CEO of OpenTug, framed the deal as more than a financing round: "Partnering with CHS and GROWMARK allows us to accelerate digital transformation across one of America's most critical supply chains. With BargeOS, we're turning data into actionable insights that help cooperatives and farmers move product more efficiently, reduce waste, and strengthen return on investment."

David Black, executive vice president and chief information officer of CHS, tied the technology to the cooperative's core promise to its farmer-owners: "Cooperatives rely on resilient, cost-effective transportation to move grain, fertilizer and other key products efficiently through the supply chain. OpenTug's platform offers a digital bridge to improve visibility and coordination across marine freight networks, and this investment will ultimately help our supply chain and the cooperative system become more efficient so we can deliver more value to our farmer-owners."

GROWMARK's Heather Thompson, enterprise marketing executive director, went furthest in her claim: "OpenTug's platform has the potential to revolutionize how products move through the river system. This investment will help strengthen the supply chains that depend on barges to move product to the right place at the right time, ultimately enabling us to better serve our farmer customers."

"Potential" is the operative word. No pilot results, uptime figures or documented demurrage savings accompany the announcement.

Who is behind the fund?

Cooperative Ventures was founded in late 2021 as a joint venture between CHS and GROWMARK, two of the largest farmer-owned agricultural supply cooperatives in North America. The fund invests in agtech startups and, beyond capital, works to build commercial relationships between those startups and its cooperative partners. Its teams operate from Bloomington, Illinois, and St. Paul, Minnesota, with management assistance from Touchdown Ventures. OpenTug joins a portfolio the fund says targets productivity, sustainability and profitability across the agricultural value chain.

Why barges matter to farm margins

OpenTug claims improved visibility and coordination can help partners move more cargo with fewer barges, and that added transparency lets cooperatives respond faster to disruptions — river closures, traffic backups, weather — and keep agricultural goods moving. Both claims point the same direction: tighter logistics, fewer wasted days, lower freight costs passed through the cooperative system to farmer-owners.

Whether those savings materialize will depend on how fully CHS rolls out BargeOS across its marine freight network, a rollout the announcement describes only as underway.
