# August 10–11 VC News Roundup: Counter-Drone, Defensive Cyber AI, Optics & Live Commerce

> Gap-fill deep-dives for deals not in PRs #69–#75: Cambridge Aerospace, Corma, Lumilens, Whatnot, Dwelly, and Aureka — who uses the products and why these funds fit.

Earlier August batches already covered Hadrian, Base Power, Onyx, Valar, Fireworks, Horizon3, and the Aug 9–10 chips/infra set. **This roundup is the gap-fill** — six deals that still needed VCT-style write-ups: who uses the product, why now, and why *this* capital.

## Snapshot table

| Company | Amount | Stage | Key capital | Job |
| --- | --- | --- | --- | --- |
| [Lumilens](/2026-lumilens-700m-series-c-ai-optical-interconnect) | >$700M | Series C @ $5.51B | [BCV](/fund/bain-capital-ventures), [Spark](/fund/spark-capital) + | Optical AI interconnect |
| [Whatnot](/2026-whatnot-545m-series-g-20b-live-commerce) | $545M | Series G @ $20B | ICONIQ / Lightspeed / Avra; [a16z](/fund/andreessen-horowitz) | Live commerce marketplace |
| [Cambridge Aerospace](/2026-cambridge-aerospace-300m-series-c-counter-drone) | $300M | Series C @ $3.4B | DFJ Growth; [Lux](/fund/lux-capital) | Low-cost drone intercept |
| [Dwelly](/2026-dwelly-170m-series-b-general-catalyst-proptech) | $170M | Series B | EQT Growth; [GC](/fund/general-catalyst) | AI lettings roll-up |
| [Aureka](/2026-aureka-biotechnologies-100m-series-b-bio-foundation-models) | $100M | Series B | Granite Asia + strategic | Bio foundation models |
| [Corma](/2026-corma-60m-seed-sequoia-defensive-cyber-ai) | $60M | Seed | [Sequoia](/fund/sequoia), [Khosla](/fund/khosla-ventures), [Coatue](/fund/coatue) | Defensive cyber FM |

## Theme 1 — Physical security still clears mega-checks

**[Cambridge Aerospace](/2026-cambridge-aerospace-300m-series-c-counter-drone)** sells the cost-exchange fix: Skyhammer interceptors for Shahed-class drones under UK MoD contract. [Lux Capital](/fund/lux-capital) returning next to a DFJ Growth lead is the defense-manufacturing tell.

## Theme 2 — AI needs wiring and a defensive brain

**[Lumilens](/2026-lumilens-700m-series-c-ai-optical-interconnect)** argues the bottleneck moved from GPUs to **photonics** — already shipping to a hyperscaler. Directory anchors: [Bain Capital Ventures](/fund/bain-capital-ventures), [Spark Capital](/fund/spark-capital), [Addition](/fund/addition), [Redpoint](/fund/redpoint-ventures).

**[Corma](/2026-corma-60m-seed-sequoia-defensive-cyber-ai)** is the other polarity: a **$60M seed** from Sequoia/Khosla/Coatue to train defensive foundation models because offense already has the AI head start.

## Theme 3 — Services and marketplaces still raise when GMV/ops prove out

**[Whatnot](/2026-whatnot-545m-series-g-20b-live-commerce)** nearly doubled to **$20B** with H1 GMV past full-year 2025 — proof consumer mega-rounds did not die in the AI year.

**[Dwelly](/2026-dwelly-170m-series-b-general-catalyst-proptech)** buys UK letting agencies and runs them on AI — [General Catalyst](/fund/general-catalyst) on an equity + debt package built for roll-up velocity.

**[Aureka](/2026-aureka-biotechnologies-100m-series-b-bio-foundation-models)** closes the loop between biological foundation models and wet lab for antibody partners — Asia-led capital, no invented `/fund/` IDs.
