Federal science.
Farm-level tools.

The USDA Agricultural Research Service produces some of the world's most rigorous agricultural science — disease resistance models, economic thresholds, water yield equations, livestock health indices, and hundreds of other research outputs that take years to develop and validate.

The problem: that science almost never reaches the farm. It sits in journals, in spreadsheets, in the institutional memory of federal researchers. AgrStak changes that.

We take peer-reviewed USDA ARS research and translate it into precise, research-grade calculators — accessible to any farmer, agronomist, or institution that needs it, with live federal data auto-populated and AI-guided interpretation built in.

One Farmer. One Stack.

Peer-Reviewed Science Only
Every model in AgrStak cites a published USDA ARS paper, federal program dataset, or documented research methodology. No guesswork, no generic AI approximations.
Live Federal Data
USDA NASS commodity prices, WASDE forecasts, APHIS biosecurity data, NRCS conservation payments, and NOAA climate normals auto-populate your calculations in real time.
Aligned with USDA One Farmer, One File
AgrStak is positioned as the computational decision layer on top of USDA's One Farmer, One File initiative — putting federal science in the hands of every connected farmer.
Patent-Pending Method
Our method of translating USDA research into farm-level calculator stacks is protected intellectual property. US Application 63/970,943 — NumeriXGPT LLC.

How AgrStak was built.

2023
The problem identified
Founded by Harry Brunache in Lawrenceville, Georgia, NumeriXGPT LLC was built on a simple observation: the USDA produces world-class agricultural science, but the tools to apply it at the farm level don't exist. The gap between federal research and practical farm decisions is enormous — and entirely unnecessary.
2024
Building the platform
AgrStak launched with its first storefronts — SF0 (Fusarium Head Blight & WGC002) and SF1 (Crop Production). Each model was built from published USDA ARS research, with direct outreach to federal researchers for validation. The provisional patent application US 63/970,943 was filed.
2025
Scaling to 30+ storefronts
The platform expanded rapidly — livestock, aquaculture, weed science, precision agriculture, carbon & climate, forestry, bee health, and more. USDA Agricultural Outlook Forum 2026 attendance established direct researcher partnerships. 431+ models now span the full agricultural stack.
2026
One Farmer. One Stack.
AgrStak V2 launches with a full platform redesign, live USDA data integrations across all storefronts, enterprise team collaboration, and VacStak — a companion platform for veterinary vaccine economics. The mission remains the same: make federal science accessible to every farmer, every day.

Built on the shoulders of
federal scientists.

Every AgrStak model is grounded in work by USDA ARS researchers whose careers are dedicated to advancing American agricultural science. We build on their published research, cite their work, and work to connect their science to the farmers who need it most.

Principles that guide
every model we build.

🧬
Science first, always
Every calculator starts with a published research paper, not a general formula. If we can't cite the science, we don't ship the model.
🌾
Built for the farmer
Research-grade doesn't mean complicated. Every model is designed so a farmer can use it in the field, not just a PhD in a lab.
📡
Live data, not stale defaults
Your calculations use today's USDA commodity prices and climate data — not averages from three years ago.
🔒
Transparent methodology
Every result shows its work. Calculation steps, source citations, and research references are visible on every output.
🤝
Aligned with federal science
We work alongside USDA researchers, not around them. AgrStak extends federal science — it doesn't replace or misrepresent it.
🏛️
Accessible at every scale
From a single producer running one calculator to a university deploying the full platform — the same research-grade tools, at every level.
