Critical mass, one investor at a time.
A path into nuclear energy, from reactor developers to the fuel and forgings they depend on. Every offering carries a signed TRL score. Every dollar releases against a certified milestone.
A reactor is a billion-dollar build, and retail capital now sits in that stack for real: community tranches beside institutional money, direct lending to the developers and suppliers who make the build possible, and municipal issues that carry no ceiling at all. Every dollar of it priced against measured engineering rather than a pitch deck.

Why this platform exists
The platforms that lasted sold real claims on real assets, verified independently. Every mechanism below is built on that finding.
An assessment engine reads NRC dockets, patents, test reports, national lab results and supplier contracts, then returns a technology readiness score with a confidence band and every citation behind it. A qualified human signs it before you ever see it.
How scoring worksFunds unlock in tranches as milestones are reached, each technology verified by an independent certifier.
See the mechanismA seed-stage supplier and a municipal power agency need different paper. Regulation Crowdfunding, Regulation A+, 506(c), an intrastate community tranche or a municipal mini-bond, chosen per offering, not imposed by the platform.

A design at the lab-bench stage should not be sold as a fixed-rate note, and a reactor already generating electricity should not be sold as a SAFE. The platform enforces the mapping rather than trusting it: an offering whose instrument does not match its TRL cannot be published.
| Band | Stage | Instrument permitted | Release | Verified by |
|---|---|---|---|---|
| TRL 1–3Tier I | Concept formulated; lab proof of principle | SAFE or Convertible note | 15% | Peer-reviewed publication; DOE award letter |
| TRL 4–5Tier I | Component validated in a relevant environment | Convertible note | 30% | Independent test report; national lab result |
| TRL 6Tier I | Prototype demonstrated in a relevant environment | Preferred equity | 50% | Third-party witness test; NRC pre-application docket |
| TRL 7Tier II | System prototype in an operational environment | Senior note | 70% | NRC construction permit; supplier contracts executed |
| TRL 8Tier II | System complete and qualified; first unit built | Fixed-rate note or Municipal mini-bond | 90% | ITAAC closure; operating license issued |
| TRL 9Tier II | Proven in commercial operation | Revenue share or Fixed-rate note or Municipal mini-bond | 100% | Commercial operation date certificate; metered output |
A design can reach TRL 8 and still be unbankable, because the scale measures demonstration and not construction cost, offtake or aging. Where that is the live question, the reviewer says so in writing beside the score.
Read the methodologyCommitting capital and handing it over are two different events. Between them sits an escrow agent and an independent certifier who has to see evidence before the next tranche unlocks.
Capital is held by a third-party escrow agent, not by the issuer and not by us.
An ITAAC closure package, a witnessed test report, an executed supply agreement, whatever the rung requires.
Not the issuer, not the platform, and not the model that generated the score.
Structured as staged closings rather than withheld proceeds, because you generally cannot hold investor money hostage after a closing.
Worked example
An offering raises $48M against a reactor at TRL 8. Investors have committed $31.2M. The issuer has $21.4M, because the first two rungs, license issuance and module-one qualification, have been certified. The remaining $9.8M stays in escrow until full acceptance criteria closure is verified.
Two tiers
TRL six is the dividing line. Below it you are funding engineering; above it you are lending against an asset that exists.
Fund the reaction.
SAFEs, convertible notes and preferred equity in reactor developers and fusion programs. Long-dated, illiquid, and genuinely capable of returning nothing. This tier requires a risk acknowledgement before you can invest, and it should be a small fraction of anyone's portfolio.
Baseload for your portfolio.
Senior and fixed-rate notes, revenue share and municipal mini-bonds against plants under construction, fuel facilities with executed supply agreements, and forges with a backlog. The evidence base is documents and metered output rather than projections.
Structure
Committed capital is held by an escrow agent. The platform never takes custody of investor funds.
Milestone verification is performed by a certifier with no economic interest in the release.
A funding portal may not also be a broker-dealer. Regulated activity sits apart from the technology company that builds the scoring engine.
The Atomic Energy Act bars licensing an entity owned, controlled or dominated by a foreign interest. Citizenship and control are screened at account opening, not patched later.
Rails available to issuers
Every issuer, project, offering, TRL score and figure on this site is invented. Nothing here is an offer to sell or a solicitation to buy any security, no securities are being offered, and no money moves.
The regulatory behavior modeled throughout, including the investment limits, the accreditation tests, the intrastate residency rules and the foreign ownership screening, is a working interpretation built from public sources.
