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 | $70M Series B | Adipose-targeted RNAi / obesity |
| Poseidon Aerospace | $60M Series A | Unmanned cargo aircraft |
| Bluecore Energy | $50M seed | Floating nuclear power |
| Yuma Energy | $35M Series A | Battery swapping |
| Split Pay | ~$100M Series B | Housing-payment lending |
Already covered by VCT in the same window
VCT already had standalone coverage for:
- Forus, which raised $150M Series C at a $3B valuation;
- Blee, whose $20M Series A was sometimes misreported as a $27M round because $27M is lifetime funding;
- CloudNC, which raised a $20M extension; and
- 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.
