# September 29–30 Funding Backfill: Helix, EliseAI, Jeeves, Reverion, Reco and More

> VCT's latest funding backfill covers the final days of September, including major AI infrastructure, vertical AI, biotech, cybersecurity, fintech, energy and structured-finance transactions.

**TL;DR:** The final days of September added another meaningful financing wave after VCT's earlier backfill. This roundup covers the deals that now have canonical startup and investment-event records, while the highest-demand companies also receive standalone articles.

## Major financings

| Company | Financing | Notes |
| --- | ---: | --- |
| [Helix Digital Infrastructure](/startup/helix-digital-infrastructure) | $1B strategic investment | Six Samsung affiliates |
| [EliseAI](/startup/eliseai) | $350M at $4B | Company says ARR >$200M |
| [Reverion](/startup/reverion) | $175M Series B | Carbon-negative power plants |
| [Jeeves](/startup/jeeves) | $110M equity | Stablecoin-native banking |
| [Efficient Computer](/startup/efficient-computer) | >$97M Series B at $650M | Energy-efficient processors |
| [AnaCardio](/startup/anacardio) | €62.5M Series B | Secondary-source record pending stronger primary verification |
| [Reco](/startup/reco-agentic-security) | $55M | Agentic security |
| [ai3Bio](/startup/ai3bio) | $48M Series A | Autoimmune therapeutics |
| [Aptadir Therapeutics](/startup/aptadir-therapeutics) | €40M seed | RNA medicines |
| [Link Cell Therapies](/startup/link-cell-therapies) | $30M extension | Series A total increased to $90M |
| [HyperGuest](/startup/hyperguest) | $25M | Hotel distribution infrastructure |
| [Modulate](/startup/modulate) | $25M | Audio-native AI |

## Smaller but strategically useful rounds

[Rig Security](/startup/rig-security) disclosed a $12M seed when it emerged from stealth, but reporting says the financing actually closed in late 2025. VCT therefore preserves the difference between **announcement date** and **financing close**.

[Atomic](/startup/atomic-supply-chain-ai) raised $12.5M Series A for AI-native supply-chain planning.

[Rayon](/startup/rayon-interior-design) raised €10M Series A for collaborative interior-design software.

[Destro AI](/startup/destro-ai) raised $8M seed for warehouse-robot orchestration.

[RemoteThreat](/startup/remotethreat) launched with $7M pre-seed for offensive cyber operations.

[Marble](/startup/marble-compliance) raised €6.5M Series A for open-source fraud and AML automation.

[ANote Music](/startup/anote-music) raised €2M for its music-royalty investment marketplace.

## September 30 additions

[Arivihan](/startup/arivihan) raised $10M Series A co-led by Accel and Prosus. Economic Times cited regulatory filings implying a valuation around ₹570 crore, while the company declined to comment on that valuation.

[EDT](/startup/edt-consumer) raised $2.4M pre-Series A led by Sauce VC.

## Non-equity capital remains separate

[Voi Technology](/startup/voi-technology) secured a €150M revolving credit facility. VCT stores it as structured/debt financing rather than counting it as €150M of venture equity.

[Kahua](/startup/kahua) announced a Bain Capital minority investment at a valuation above $1B. The company did **not** disclose the investment amount, so VCT leaves the amount undisclosed despite secondary databases showing larger numbers.

## Why this is the right publishing model

The final September batch reinforces the same editorial rule as the earlier backfill:

- large brand/search opportunity → standalone article + permanent profile + event;
- meaningful but lower-demand financing → permanent profile + event + roundup;
- debt, credit and mixed financing → explicitly classified rather than merged into venture totals;
- weak secondary evidence → kept behind a draft review gate.

This gives VCT broad coverage without creating dozens of disposable funding-news URLs.
