In deep tech, the minimum viable product is the minimum credible evidence that your core technical claim is true — and for physics-heavy hardware, that evidence is usually a simulation-built virtual prototype. It's how funded teams de-risk their first Army xTech & Army SBIR proposal and their first raise, before spending on tooling.
The single technical claim that, if true, makes you fundable. The MVP exists to test that — nothing else.
Build the virtual prototype in the physics that carries the claim: Mechanical (FEA), Fluent (CFD), HFSS/Maxwell (EM), or a coupled model.
Sweep the design against your requirement. Every failure found in the solver is a prototype you didn't machine.
Converged results become the performance curves, margin tables, and contour plots funders and investors evaluate.
Autonomous, uncrewed wing-in-ground-effect (WIG) craft that skim just above the water surface to move cargo cheaply and without ports or runways.
Named a winner of xTechSearch 9 in the contested-logistics-and-sustainment domain, earning cash and an Army SBIR lane.
WIG craft live or die on ground-effect aerodynamics and structural loads at the air-water interface — exactly the aero (Fluent/CFX) and structures (Mechanical) work simulation is built for.
Spatial-AI and mixed-reality platform; its Army entry modernized paint and camouflage workflows for vehicle sustainment.
One of just 24 winners from 900+ applicants in xTechSearch 9.
Digital-twin and geometry-heavy AI workflows pair naturally with simulation data that describes how a surface and its coating behave.
Honolulu-based engineering firm developing maritime and contested-logistics systems for the Indo-Pacific.
An xTechPacific winner that parlayed the prize into follow-on Army and Navy contract work.
Maritime autonomy and vessel structures depend on CFD (Fluent/CFX) hydrodynamics and structural fatigue analysis (Mechanical).
A small defense-tech firm whose xTechSearch 7 win led directly into an Army SBIR Phase I contract and new transition leads.
Converted an xTechSearch prize into an Army SBIR Phase I award and an experimentation-event transition path.
The classic prize-to-SBIR journey where a validated engineering model carries the technical volume from concept into a funded contract.
Quantum-sensing company applying optically-pumped magnetometers to defense positioning, navigation and detection problems.
Selected among xTechPacific winners advancing through the live experimentation event.
Quantum-sensor packages need tight electromagnetic (HFSS/Maxwell) and thermal (Icepak) control to hold sensitivity in a rugged enclosure.
