## Roundup only

### YC Summer 2026 Demo Day — today, not a financing

[YC’s Demo Day page](https://www.ycombinator.com/demoday) and the [2026 dates post](https://www.ycombinator.com/blog/2026-demo-days) put **Summer 2026 Demo Day on Thursday, September 10**. Invite-only; about **1,500** investors and media (YC). Batch-size figures of **234–235** circulating in directories are **not** a YC official count used here. The live apply window remains **Winter 2027** (on-time **November 2**). See the [YC guide](/yc-fall-2026-application-deadline-interview-guide). **No batch-wide round sizes** in this index.

### Limetax — €6M equity, €30M credit, not €36M equity

[Sesame, September 9](https://www.sesamers.com/funding/limetax-raises-36m-german-tax-firms/): Berlin tax-firm roll-up. **€6 million pre-seed** led by Motive Partners plus a **€30 million** German-bank **credit facility**. Headline **€36 million** is **mixed**. No `/startup/limetax`. Too small and too structured for a standalone on this tape.

### UniPat AI — $300M / $2.5B talks, not a close

[Bloomberg, September 10](https://www.bloomberg.com/news/articles/2026-09-10/alibaba-backs-ex-staffer-s-ai-testing-lab-at-2-5-billion-value): Alibaba **slated to lead** about **$300 million** at **$2.5 billion**; Tencent and HSG named; **talks remain in progress**. **Not a close.** No entity this pass.

### FRYTE Mobility — €3.5M seed

Munich eTruck charging software; **€3.5 million** seed (Tech.eu / company). Below the standalone bar here.
