Veteran finance leader who guided three companies through IPOs joins ClickHouse as it surpasses $350 million in run-rate revenue
ClickHouse, Inc., the company behind the leading database for AI, announced the appointment of Michael Scarpelli to its Board of Directors. Scarpelli most recently served as Chief Financial Officer of Snowflake, and previously held the CFO role at ServiceNow and Data Domain, leading each company through its initial public offering. He will serve as an independent director and chair the board’s Audit Committee.

Scarpelli joins ClickHouse during a period of growth that is unusual even by the standards of the current AI cycle. The company has surpassed $350 million in run-rate revenue, up from roughly $200 million at the end of 2025. Scarpelli joins ClickHouse as more than 4,000 customers, including DoorDash, Ramp, Meta, Tesla, Cisco and Visa, build the applications that define their businesses on infrastructure that does not force a choice between speed, scale, and cost.

Earlier this year the company was valued at $15 billion in a Series D funding round, which was extended to include J.P. Morgan Private Capital, BDT & MSD Partners, Craft Ventures, and 20VC. ClickHouse now employs nearly 800 people across 27 countries, with plans to reach 1,000 by year-end, and derives more than half of its revenue from outside the United States.
“Bringing Mike onto our board is a statement about the kind of company we are building. He has scaled consumption businesses through some of the largest software IPOs in history with a discipline around unit economics that is rare at growth stage,” said Aaron Katz, co-founder and CEO of ClickHouse. “Customers choose ClickHouse because it comes down to price and performance, and we win on both. We ingest and query data at a speed and efficiency no other technology can match, and the value compounds as workloads and use cases grow. As AI agents become the dominant consumers of data, that advantage will only widen. Our job now is to build a world-class enterprise motion on that foundation without losing the developer-first mindset and efficiency that got us here, and Mike is the right person to help us do it.”

Over a career spanning more than three decades, Scarpelli has helped generate more than $100 billion in shareholder value. “Every generation of infrastructure has a company that redefines the category, and for real-time and agentic workloads that company is ClickHouse,” said Scarpelli. “Enterprises are drowning in data tools, and every CFO and CIO I know is trying to consolidate onto fewer platforms that can do more. It is a hard market to win with hundreds of options, and most vendors solve one problem. ClickHouse started with real-time analytics and is now taking on more of the data estate, from data warehousing and observability to agent observability and transactional workloads, on infrastructure that is faster and dramatically more efficient than what it replaces. The expansion I see in this customer base is unlike anything I have seen in my career. Aaron, Yury, Alexey, and the ClickHouse team have paired a category-defining product with a business model built for durability, and I am excited to help them build a generational company.”
Scarpelli’s appointment is part of a deliberate build-out of ClickHouse’s finance and governance capabilities, including the 2025 hire of Chief Financial Officer Jimmy Sexton, who previously spent six years in finance leadership at Snowflake, including leading investor relations, and earlier held finance roles at ServiceNow.
