The MVP Playbook

Your MVP isn't a prototype. It's proof.

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 AFWERX / SpaceWERX — STRATFI & TACFI proposal and their first raise, before spending on tooling.

The process

Four steps from claim to fundable evidence

1 · Define the one claim

The single technical claim that, if true, makes you fundable. The MVP exists to test that — nothing else.

2 · Model the physics

Build the virtual prototype in the physics that carries the claim: Mechanical (FEA), Fluent (CFD), HFSS/Maxwell (EM), or a coupled model.

3 · Iterate in software

Sweep the design against your requirement. Every failure found in the solver is a prototype you didn't machine.

4 · Package the evidence

Converged results become the performance curves, margin tables, and contour plots funders and investors evaluate.

Teams that funded on simulation evidence

Hermeus

Reusable hypersonic aircraft (Quarterhorse), pursuing Mach 5 flight.

Won a ~$1.5M AFWERX contract in 2020 and a ~$60M follow-on in 2021; has since flown a demonstrator.

Hypersonic vehicle development leans on high-speed CFD and aerothermal-structural analysis to survive the thermal environment.

Ursa Major

Independent rocket-propulsion company building storable and oxygen-rich staged-combustion engines.

Backed by Air Force and Space Force SBIR/innovation work; has raised ~$150M in private capital, illustrating the matched-money model.

Engine development depends on combustion and conjugate-heat-transfer CFD plus structural analysis of the thrust chamber and turbomachinery.

Slingshot Aerospace

Space situational awareness and space-domain-awareness software and data products.

A frequent Space Force / SpaceWERX partner scaling on defense and commercial contracts (funding figures ~ and unconfirmed).

Mission and orbit modeling (coverage, conjunction, catalog maintenance) underpins the SDA analytics.

Firefly Aerospace

Small-to-medium launch vehicles and lunar landers.

Has worked with Air/Space Force programs and reached a reported ~$3B valuation, showing the trajectory from small contracts to scale.

Launch-vehicle work spans propulsion CFD, structural launch loads, and separation dynamics.

A representative Orbital Prime team

An in-space servicing/debris-remediation startup entering via SpaceWERX Orbital Prime Direct-to-Phase-II.

Orbital Prime D2P2 awards have run ~$1.7M each — a realistic on-ramp for a pre-revenue ISAM team with a research partner.

Rendezvous-and-capture concepts need orbit/mission modeling plus structural and thermal analysis of the servicing spacecraft.
