VC Deal Radar — Week of June 23, 2026

Week in one screen

Screening window: June 22 after the prior issue through June 29, 2026, 00:00 (UTC+8). I found 12 confirmed scoped financing announcements tied to a16z, Sequoia Capital, or Y Combinator. Disclosed capital totaled $525.3 million.

a16z / Andreessen Horowitz: 5 confirmed announcements, led by Mirendil, Probook, Netris, Ornn, and Prosper AI.
Sequoia Capital: 2 confirmed announcements, Probook and Sail Research.
Y Combinator: 7 confirmed financing announcements where YC was named as a participant, existing backer, or batch link.
Exits: no confirmed exits surfaced from the scoped firms in this window.

The week was unusually concentrated in AI infrastructure and agent infrastructure. The largest reported round was Mirendil's $200 million seed at a $1 billion valuation, followed by Sail Research's $80 million Seed/Series A package and Warp's $60 million Series B.

Coverage audit

The count includes only announcements where a scoped firm was explicitly named in an official company announcement, an official investor post, or verified press coverage. I did not count a16z-backed Base Power's Illinois rollout because the June 25 article was a market-expansion story, not a new financing; it referenced a16z's 2025 investment round instead. 18

I also excluded social-only funding snippets, Peak XV references that did not name Sequoia Capital US/Global, and older Ornn funding material from 2025. The Ornn row above uses the June 2026 a16z crypto investment note and June 2026 press coverage, not the older 2025 PR Newswire item.
