Nebraska-based startup DARO has closed a $2.5 million funding round to expand its swine disease testing capacity. The investment follows a $1.1 million seed round raised by the company in early 2025.
Why it matters
The investment supports the scaling of diagnostic tools aimed at addressing Porcine Reproductive and Respiratory Syndrome Virus (PRRSV), which imposes a $1.2 billion annual cost on the swine industry. Costs associated with the virus have risen 80% since the mid-2000s.
DARO utilizes patent-pending diagnostic technology to identify swine pathogens. The platform addresses a PRRSV burden that now costs the U.S. industry $1.2 billion annually, an 80% increase since the mid-2000s.
The players
DARO
A Nebraska-based agricultural technology startup developing proprietary diagnostic testing for the swine industry.
Grit Road Partners
A venture capital firm focused on agricultural technology and early-stage startup investments.
Invest Nebraska
A statewide economic development organization that provides capital and support to growing Nebraska enterprises.
Nelnet
A Lincoln-based financial services and technology company that participates in regional venture capital investments.
The details
DARO is scaling its laboratory, data, and commercial systems to increase the throughput of its disease testing platform. The company employs patent-pending diagnostic technology, a proprietary method for pathogen detection, to identify specific viral markers in swine populations. This testing is critical in Nebraska, which maintains a population of 3.5 million pigs and accounts for $2 billion in annual hog sales.
Timeline
2022: Nebraska hog sales reached $2 billion.
Early 2025: DARO closed a $1.1 million seed round.
March 2025: Nebraska swine population reached 3.5 million.
October 6, 2026: DARO announced the $2.5 million funding close.
The Tech Race
The firm enters a market where PRRSV costs have surged 80% since the mid-2000s, necessitating more scalable diagnostic alternatives. DARO is competing to standardize high-throughput testing in a sector that currently faces a $1.2 billion annual economic impact.
The expansion will increase testing throughput for Nebraska producers managing the state's 3.5 million pigs. While details on specific commercial service dates remain unannounced, the scaling of this technology aims to provide faster diagnostic results for pork operations.
The takeaway
The swine industry is increasingly reliant on data-driven diagnostics to manage a $1.2 billion annual viral cost. Industry observers should watch for DARO's upcoming capacity benchmarks to see if the firm effectively scales testing throughput.
