Sequoia wrote 2 checks in the last two weeks — 2 as lead (~$266M deployed). Led: Whop ($200M Growth (Series C+)), Blacksmith ($66M Growth (Series C+)). The pattern in the checks: devtools with checks between $66M and $200M. A firm leading at that pace has capital to deploy now; this is the quarter to get in front of them.

Tomasz Tunguz sizes the AI buildout against the 1990s telecom cycle: $516b of US venture investment in the first nine months of 2026, 44% above the full-year 2021 record, 82.7% of this year's deal value into AI companies, and 80% of the largest AI spenders are themselves venture-backed. The money is abundant and concentrated, so before a partner meeting decide which side of that circle you sit on and bring revenue that does not depend on other people's venture dollars. Read it.
