YC Summer 2026 Demo Day — today, not a financing

YC’s Demo Day page and the 2026 dates post 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. No batch-wide round sizes in this index.

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

Sesame, September 9: 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: 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.

Explicitly not this index

  • Jet Zero, Navana, Cato, Jaipur, Fundly, Molten, W Health — open PR #140.
  • Mistral €3 billion Series D — merged PR #141. See the memo.
  • Cognition $2 billion / $48 billion, Stoke, TEC, Forus, Sapien — open PR #142.
  • Antioch, TrueBridge, Blee, CloudNC, PHYMI, Herdr — open PR #143.
  • Lightfield, Cymphony, Euno, Buildcheck, Bulwark — open PR #144.
  • Nua $50 million mixed Series C — already on September 6–7.

Harvey’s $550M Print Is $15.5B Company, $15.6B Bloomberg — Blog Omits ARR

Harvey announced $550 million at a $15.5 billion valuation on September 9, 2026, co-led by Diffusion and Lightspeed. Bloomberg printed $15.6 billion. The company blog and Reuters did not name a series letter or print ARR. LawSites attributed $400 million ARR to a Weinberg LinkedIn post we did not retrieve.

Clay’s $115M Series D Is $7.1B — ARR Last Printed at $100M in December

That is 2.3× the August 2025 $3.1 billion Series C and 42% above the January 2026 $5 billion employee tender. The Series D wire did not print current ARR. December 2025 $100 million ARR is the last company stock.

Covenant’s $250M Is Lifetime Capital at Stealth Exit — Not a September Round

Covenant unveiled Anthem, a heavy-payload cruise missile, on September 9, 2026. Founder Michael Kaufman (a16z) said the 2024 company has raised $250 million. Reuters said just over $250 million from a16z, Founders Fund, Lux, 8VC, Aleph, and Lightspeed. Valuation was not disclosed. About $150 million of orders is Reuters, not the founder post.
