David Cahn
Snapshot
Partner / GP at Sequoia Capital (Menlo Park / SF). AI-infrastructure investor — compute, data centers, power, the economics of the AI build-out. Best known publicly as the author of Sequoia’s “AI’s 600B Question” — the most-cited skeptical-but-bullish framing of the gap between AI capex and AI revenue. For init.inc he is a relationship-only POC: Sequoia is structurally conflicted (leads two direct competitors), so Cahn cannot invest this round.
Background
- Sequoia Capital — Partner (current). Focus: AI infrastructure / compute economics.
- Coatue Management — previously General Partner & COO of Venture, where he led/helped lead enterprise & AI-infra investments (HuggingFace, Runway, Supabase among those associated with his Coatue tenure) ^[single-source — LinkedIn-derived; Coatue does not publish per-partner deal attribution]. The Coatue→Sequoia move is the key career arc.
- Education / earlier career: not fully verified here ^[needs-research] — moderate-depth page (conflicted firm).
Investing
- Thesis: the AI build-out is real but the return-on-compute question is unresolved — GPU data centers have weak pricing power (GPU compute commoditizing, metered hourly, new entrants flooding in vs the CPU-cloud oligopoly), and last-gen chips (H100s) depreciate faster than the market prices in. The “$600B Question” = NVIDIA’s projected data-center run-rate revenue implies an AI-revenue gap that has to be filled. Framed as “a time lag, not a bubble.”
- Focus areas: AI infrastructure, compute/power, data centers, enterprise software (carryover from Coatue).
- This thesis is orthogonal to init.inc’s wedge (back-office services-as-software / AI-ITSM) — which is part of why, even setting aside the firm conflict, Cahn is not a natural thesis match.
Public voice
- Writing: “AI’s 600B Question” (Sequoia post; also on his Substack); follow-on “AI is Now Shovel Ready” (Substack). These are the canonical pieces — quote-mine them for his views on AI unit economics.
- Podcasts/video: 20VC with Harry Stebbings — “Sequoia’s David Cahn on AI’s 600 Billion Question” (Spotify).
- Social: LinkedIn david-cahn-60150793 (matches the handle in the CRM). X presence exists but not verified to a specific handle here ^[needs-research].
Personal & interests (rapport)
Light for this conflicted-firm page. His public identity is tightly built around the AI-capex / data-center-economics debate; any rapport angle runs through that intellectual lane (the “is AI a bubble or a time-lag” conversation). Deeper personal research deferred ^[needs-research].
Fundraise Relationship (init.inc)
- Status: ⚠️ Conflicted — relationship/intel only. Sequoia is structurally locked out (leads Serval + Edra, plus the Anthropic services JV). Cahn is not on either competitor’s deal team, but the firm cannot write the check.
- Conversation log (CRM, newest first):
- 2026-04-28 — Kushal flagged Sequoia Conflicted; tracking Cahn (Partner/GP) for relationship-only, firm cannot invest. Kushal: “not very warm.”
- Mutual connections / warm path: Kushal (the connector who flagged him).
- Personal & rapport notes: His public identity centers on the AI-economics / data-center-economics debate, not back-office-ITSM (off his thesis).
- Live stage: CRM — Conflicted (relationship-only).
Cross-check vs existing wiki
Consistent with sequoia-capital (Fundraise intel section) and the CRM row. No contradiction. The “AI’s $600B Question” / compute-economics identity is corroborated by both Sequoia’s own post and his Substack (≥2 independent sources).
