# September 1–8 Funding Backfill: Moonwalk, Poseidon, Bluecore, Split Pay and Yuma

> A VCT backfill for the first week of September covering obesity biotech, unmanned cargo aircraft, floating nuclear power, housing-payment fintech and battery swapping.

**TL;DR:** VCT's September 1–8 backfill closes several meaningful gaps while connecting them to existing coverage from the same week.

## Newly added

| Company | Financing | Focus |
| --- | ---: | --- |
| [Moonwalk Biosciences](/startup/moonwalk-biosciences) | $70M Series B | Adipose-targeted RNAi / obesity |
| [Poseidon Aerospace](/startup/poseidon-aerospace) | $60M Series A | Unmanned cargo aircraft |
| [Bluecore Energy](/startup/bluecore-energy) | $50M seed | Floating nuclear power |
| [Yuma Energy](/startup/yuma-energy) | $35M Series A | Battery swapping |
| [Split Pay](/startup/split-pay) | ~$100M Series B | Housing-payment lending |

## Already covered by VCT in the same window

VCT already had standalone coverage for:

- [Forus](/startup/forus), which raised $150M Series C at a $3B valuation;
- [Blee](/startup/blee), whose $20M Series A was sometimes misreported as a $27M round because $27M is lifetime funding;
- [CloudNC](/startup/cloudnc), which raised a $20M extension; and
- [Gridsight](/startup/gridsight), which raised $26M for grid-capacity software.

## Three infrastructure themes stand out

### Power

Bluecore's floating nuclear model and Gridsight's grid software show that AI-era infrastructure funding is moving both toward more generation and better use of existing electricity networks.

### Physical logistics

Poseidon is applying autonomy to cargo aircraft, while Yuma is scaling physical battery-swapping infrastructure across Indian cities.

### Healthcare and biotech

Moonwalk and Forus sit at very different points in healthcare: Moonwalk is developing new medicines, while Forus is trying to make approved medicines reach patients faster.

## Why the normalized event layer matters

Split Pay is the best example from this batch.

Its $125M headline represents a $25M Series A plus an approximately $100M Series B. VCT stores the latest financing as the Series B amount rather than copying the cumulative A+B headline into a single-round field.
