The Twenty Minute VC (20VC): Venture Capital | Startup Funding | The Pitch - 20VC: The AI Bubble Is Wrong | AI Margins Need to Improve | Revenue Concentration Should be a Concern | Why People Over-Estimate Open Models But Enterprises Still Fear Frontier Models with Aaron Katz, ClickHouse
Aaron Katz, founder and CEO of ClickHouse, joined Harry Stebbings for a 20VC episode recorded at Craven Cottage, Fulham Football Club – a unique setting reflecting ClickHouse's recent front-of-shirt sponsorship. Katz introduced ClickHouse as the world's most popular open-source analytical database, known for lightning-fast queries and resource efficiency, used by leading AI-native companies like Anthropic, OpenAI, Tesla, and Netflix. ClickHouse boasts an astounding revenue trajectory: zero, 12, 50, 200, and finishing the current year north of $500 million ARR, aiming for $1 billion ARR before December 2027.
Katz shared his perspective on the current AI cycle, noting its "unprecedented pace" of acceleration compared to previous tech shifts (internet, mobile, social). This rapid growth translates into new demands on systems and revenue scaling "unlike anything we've seen in our lifetime." While acknowledging concerns about lower gross margins in some AI companies, he believes they are acceptable for now, given the rapid growth and healthy balance sheets, provided there's a clear path to margin expansion. For investors, he emphasizes revenue *durability*, contrasting the high switching costs of infrastructure software like ClickHouse with the potentially low switching costs of "agentic applications" where model providers are rapidly leapfrogging each other.
Internally, ClickHouse experienced an "AI awakening," leading to a 100x increase in Anthropic spending. Katz prioritizes sustained revenue growth over strict token budgeting, noting that token costs are declining, and AI tooling is accelerating their roadmap, allowing them to ship products faster and enter new categories years ahead of schedule. He reflected that ClickHouse has been "too efficient," specifically regretting not investing more in sales capacity earlier. His initial strategy, inspired by Datadog's PLG approach, focused on product and engineering, but he now sees the necessity of layering in an enterprise sales motion, drawing lessons from his 12 years at Salesforce under Marc Benioff.
Looking to the future, Katz highlighted the shift from building for humans to building for autonomous agents. Agents don't have personas, demand low latency, and exhibit unpredictable, exploratory query patterns. He envisions a future where agents need identity, budget, and authorization to consume services, and where they will ultimately select the underlying infrastructure stack (like ClickHouse) for applications they build. He predicts that while some specialized models will thrive (e.g., legal tech), large frontier labs will remain dominant. He controversially suggests a 50-50 split between open-weight and frontier models for enterprise adoption, citing concerns about legal protections and indemnification with open-weight models, particularly those originating from China.
Katz noted a trend of enterprises, including digital-native companies, considering moving back to on-prem deployments due to privacy, compliance, and security concerns. This requires ClickHouse to support multiple deployment models. His biggest competitive fear is "the next ClickHouse" – a disruptive technology emerging from the "rearview mirror," as ClickHouse itself disrupted incumbents.
On fundraising, Katz revealed that ClickHouse had a billion dollars on its balance sheet and didn't *need* the recent capital infusion but valued the strategic investors like David Sacks, Michael Dell, and JP Morgan. He views fundraising as a means to build a durable, long-lasting, generational company, not just for short-term valuation bumps. He anticipates hitting $1 billion ARR "within the next two years, if not sooner."
Talent acquisition in the AI world is challenging, but ClickHouse leverages its global distribution across 27 countries to hire experienced database engineers, maintaining single-digit attrition. While acknowledging the value of in-person collaboration, his company's distributed nature is driven by the need to support customers across diverse time zones and languages, making centralized hubs impractical.
Katz is excited about medical advancements, particularly in chronic conditions. Regarding ClickHouse's future, he sees no rush to go public, believing the company will thrive regardless of its public status in the next few years. He noted that public markets are currently "irrational," and being private offers protection from volatile stock prices and short-sellers, while structured secondaries provide employee liquidity. He acknowledges the benefits of public awareness and a tradable currency for M&A but argues that large private companies like Stripe and OpenRouter are now demonstrating that significant acquisitions are possible without being public.
