ClickHouse CEO: AI Margins Need to Improve | Revenue Concentration Should be a Concern
Aug 31, 2026 · 1:05:57
Aaron Katz, co-founder and CEO of ClickHouse, tells Harry Stebbings the AI cycle is 'just getting started' — revenue growth is unprecedented, but the biggest risk is revenue durability because agentic apps have low switching costs. He accepts lower gross margins if expansion is possible, measures AI token spend by ROI, and predicts agents will have identities, budgets, and pick their own infrastructure. He argues open-weight models won't win the enterprise over trust concerns, and sees enterprises moving back on-prem. ClickHouse revenue went 0, 12, 50, 200, finishing north of 500 this year, with >200% NDR; Katz would take the under on $1B ARR by December 2027. He calls the $2B Series B with no product the priciest round; revenue concentration matters — AI customers are under 12% of revenue.
