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.

| Jeeves | $110M equity | Stablecoin-native banking |

Smaller but strategically useful rounds
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 raised $12.5M Series A for AI-native supply-chain planning.
Rayon raised €10M Series A for collaborative interior-design software.
Destro AI raised $8M seed for warehouse-robot orchestration.
RemoteThreat launched with $7M pre-seed for offensive cyber operations.
Marble raised €6.5M Series A for open-source fraud and AML automation.
ANote Music raised €2M for its music-royalty investment marketplace.
September 30 additions
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 raised $2.4M pre-Series A led by Sauce VC.
Non-equity capital remains separate
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 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.
