VC Deal Tracker: a16z, Sequoia & YC — Issue #4 (June 25–July 2, 2026)

This was a concentrated week: fewer tracked investors on the tape, but one very large Sequoia-linked defense round and two portfolio exits changed the mix. Public announcements dated June 25 through July 2, 2026 produced five new investment entries and two exit entries, with roughly $853 million in disclosed financing or IPO proceeds, plus one acquisition with undisclosed terms.

What changed this week

AI infrastructure stayed broad, not just model-layer. Netris is selling network automation to AI neoclouds; Sail is attacking the inference and runtime layer for long-running agents. Both are picks-and-shovels bets, but at different depths of the stack: one around GPU-cluster operations, the other around the economics of agent workloads.

Sequoia’s biggest visible move was outside classic software. STARK’s €500M defense round dwarfed the rest of this issue. It also pushed the sector mix away from pure AI tooling and toward sovereign, NATO-aligned autonomous systems.

YC signals split between new funding and exits. Pocket and Aseon Labs were current-round participations; Hey Revia was a liquidity event. That makes this week less about a single YC batch theme and more about YC-backed companies showing up across hardware, mobility operations and healthcare workflow automation.

Watch next

Whether AI neocloud tooling keeps consolidating around operators with real GPU demand, not just AI branding.
Whether European defense-tech rounds continue to pull top-tier Silicon Valley investors into NATO-aligned hardware and autonomy.
Whether Lime’s public-market reception resets exit expectations for older consumer-mobility companies still carrying pandemic-era balance-sheet scars.
