C3.ai Leadership
Who founded C3.ai, who runs it today, who sits on the board, and how the dual-class Class A / Class B voting structure keeps voting control concentrated with founder Thomas Siebel even after his September 1, 2025 transition out of the CEO seat. Sourced from C3.ai's most recent DEF 14A proxy statement filed August 21, 2025, plus the Item 5.02 8-Ks for the CEO transition and the November 2025 board expansion.
Sibling page: C3.ai Financials — the post-FY events panel surfaces the CEO transition, the February 2026 restructuring, and the April 2026 C3 Code launch as discrete cards. Roster row: C3.ai on /orgs/.
CEO transition — September 1, 2025
On September 1, 2025, the C3.ai board appointed Stephen Ehikian as Chief Executive Officer. Founder Thomas M. Siebel — who had served as CEO since founding the company as C3 Energy in January 2009 — transitioned to Executive Chairman, retaining his board seat and the Class B common stock holdings that anchor the voting structure described below. The transition is the first CEO change in C3.ai's history. Ehikian was previously co-founder and CEO of Airkit.ai (acquired by Salesforce November 2023), VP of AI Products at Salesforce after that acquisition, and Acting Administrator and Deputy Administrator of the U.S. General Services Administration from January to July 2025.
Ehikian's appointment is the first event in a sequence the company's Financials page tracks as the post-FY2025 narrative: the CEO transition (September 1, 2025) → the February 24, 2026 restructuring plan that eliminated 26% of the global workforce and roughly 30% of annualized non-employee costs → the April 8, 2026 C3 Code launch, the autonomous-agentic-coding product line that Ehikian framed as the company's pivot from "assisted development" to "AI designing and building Enterprise AI."

Founder
C3.ai is a single-founder company. Thomas M. Siebel founded it as C3 Energy in January 2009, renamed it C3 IoT in 2016 and C3.ai in June 2019, and led it through the December 9, 2020 IPO on the New York Stock Exchange under ticker AI. He served as CEO from founding until September 1, 2025; he remains on the board and now holds the Executive Chairman title. The founder-CEO continuity from 2009 to 2025 is itself one of the more distinctive things about C3.ai's leadership, ended only by the September 2025 transition.
Founded and ran Siebel Systems, the global CRM software company, before its January 2006 merger with Oracle Corporation. Earlier, served in various leadership positions at Oracle from January 1984 to September 1990. Holds a B.A. in History, an M.B.A., and an M.S. in Computer Science, each from the University of Illinois at Urbana-Champaign. Author of four books, most recently Digital Transformation: Survive and Thrive in an Era of Mass Extinction (RosettaBooks, 2019). Currently serves as a member of the College of Engineering boards at the University of Illinois at Urbana-Champaign and the University of California, Berkeley; elected a member of the American Academy of Arts and Sciences in April 2013.
At C3.ai, founded the company as C3 Energy in January 2009 (renamed C3 IoT 2016, C3.ai June 2019). Served as Chairman of the Board since founding and as Chief Executive Officer from July 2011 through September 1, 2025. Holds the Class B common-stock position that, alongside his Class A holdings, gives the directors-and-officers group as a whole approximately 52.3% of voting power under the dual-class structure described below — a concentration largely attributable to Siebel personally.
Current executive officers
The August 2025 proxy listed three executive officers as of August 4, 2025 (Siebel as CEO, Lath as CFO, Schilling as EVP/CCO). The September 2025 Item 5.02 8-K replaced Siebel with Ehikian in the CEO seat; Lath and Schilling continue. Siebel remains a Section 16 officer in his Executive Chairman capacity. The February 2026 restructuring 8-K (Item 2.05 — costs of exit / disposal) cut 26% of the global workforce but did not separately disclose officer departures, so the post-Sept 2025 officer roster remains the current one as of April 30, 2026.

Mike Clayville
II
—
Veteran enterprise-sales leader (former AWS, Stripe)
Nov 2025
Class II director; elected November 9, 2025 when the board increased its size from eleven to twelve to fill a newly created directorship; term holds until the 2028 Annual Meeting. Independent non-employee director per the Item 5.02 8-K filed November 13, 2025. Compensation: a $350,000 grant-date-fair-value option award under the 2020 Equity Incentive Plan, vesting 12.5% quarterly over two years; no cash compensation. The 8-K does not include a biographical summary; per contemporaneous reporting Mr. Clayville's most recent operating roles were senior enterprise-sales leadership positions at AWS and Stripe.
Ages and director-since dates as listed in the August 2025 proxy except for Mike Clayville, sourced from the November 2025 Item 5.02 8-K. The 2025 Annual Meeting was held October 3, 2025; the Class II nominees (Hyten, Levin, Sewell) were re-elected for terms expiring at the 2028 Annual Meeting. The "current term expires" column above reflects the term end as of the August 2025 proxy record date (before the October 3 vote); after the vote, Hyten / Levin / Sewell rotate forward to 2028.
Voting structure — Class A and Class B common stock
C3.ai has two classes of common stock outstanding: Class A common stock, with one vote per share, and Class B common stock, with 50 votes per share. Both classes vote together as a single class on all matters submitted to stockholders, including the election of directors, except in limited circumstances. The two classes are economically equivalent in dividend and liquidation rights.
As of the August 4, 2025 record date for the 2025 Annual Meeting, there were 134,027,425 shares of Class A common stock outstanding and 3,499,992 shares of Class B common stock outstanding. The 50-to-1 voting ratio means the small Class B float (≈2.5% of share count) carries roughly 56.6% of the per-share-equivalent voting power on the record date.
The August 2025 proxy's beneficial-ownership table shows that all directors and officers as a group (14 persons) held 33,370,362 shares of Class A and 3,072,820 shares of Class B — 87.8% of all Class B common stock outstanding — representing approximately 52.3% of the total voting power of Class A and Class B combined. The Class B holdings are concentrated in entities affiliated with founder Thomas M. Siebel (the Siebel Living Trust dated 7/27/1993, First Virtual Holdings, and other Siebel-affiliated vehicles). The September 2025 CEO transition did not change this voting structure; Siebel retained his Class B holdings on stepping into the Executive Chairman role.
Practical effect: even after stepping down as CEO, Siebel remains the single most consequential voter at C3.ai annual meetings, and the directors-and-officers-as-a-group bloc commands a majority of the company's voting power. The dual-class structure does not have a sunset trigger of the kind some peers have adopted (Snap, Lyft, etc.); the proxy does not describe a Class B conversion mechanism that would collapse the 50-to-1 ratio on a fixed date or threshold.
Notable transitions and departures
C3.ai's leadership has been unusually stable for a public company — Thomas Siebel held the founder-CEO role continuously from 2009 until September 2025. The post-IPO era's most material change is the September 2025 CEO transition itself; the February 2026 restructuring did not separately disclose officer departures. The list below reflects post-IPO transitions documented in C3.ai's SEC filings.
Thomas M. Siebel
Sept 1, 2025
Stepped down as CEO after 14 years; transitioned to Executive Chairman; retained board seat and Class B holdings.
Disclosed in the Item 5.02 8-K filed September 5, 2025. The transition was the first CEO change in the company's 16-year history. Siebel did not retire — he continues as Executive Chairman and remains a Section 16 reporting officer; the change was structurally an ownership-and-governance continuity move, not a clean exit. The September-2025-to-April-2026 sequence (CEO transition → February-2026 26%-workforce restructuring → April-2026 C3 Code launch) is best read as one integrated leadership-driven repositioning.
Pre-2025 officer departures (e.g. earlier CFO and product-leadership transitions) are not enumerated here — the page intentionally focuses on the post-IPO, 2025-onward leadership sequence that is the primary visitor question. Future Section 16-officer departures will be added in the same matched-set shape.
The September-2025-to-April-2026 transition arc
Read together, four events between September 2025 and April 2026 form a single arc that is the post-IPO era's most material story for C3.ai's leadership:
September 1, 2025 — CEO transition. Stephen Ehikian appointed CEO; founder Thomas Siebel transitions to Executive Chairman, retaining his board seat and Class B holdings. First CEO change in the company's history. Disclosed via Item 5.02 8-K.
September 14, 2025 — 2025 Inducement Plan adopted. Board adopts the C3.ai 2025 Inducement Plan reserving 5,000,000 shares of Class A common stock to fund Ehikian's $20M RSU and $15M stock-option inducement awards plus future hires under NYSE 303A.08. Item 5.02 8-K filed September 18, 2025.
November 9, 2025 — board expansion. Board increases its size from eleven to twelve and elects Mike Clayville (a senior enterprise-sales operator from AWS and Stripe) to fill the new Class II directorship. Item 5.02 8-K filed November 13, 2025.
February 24, 2026 — restructuring plan. Board approves a restructuring plan that includes a 26% reduction in C3.ai's global workforce (substantially completed at announcement) and approximately 30% reduction in annualized non-employee costs (targeted for completion in the second half of fiscal year 2027); $10–12M in pre-tax restructuring charges. Item 2.05 8-K filed February 25, 2026. The 8-K does not separately disclose officer departures, so the post-Sept 2025 named-executive-officer roster (Ehikian, Siebel as Executive Chairman, Lath, Schilling) continued through the restructuring as the current officer cohort.
April 8, 2026 — C3 Code general availability. The post-restructuring product pivot. C3 Code is C3.ai's autonomous-agentic-coding platform; Ehikian framed it as a structural shift from "assisted development" to "AI designing and building Enterprise AI." Constellation Research read the launch as the first installment of the post-restructuring turnaround plan. c3.ai press release (April 8, 2026).
Three of those four events are disclosed via Section 16-officer-and-director 8-Ks (Item 5.02 or Item 2.05); the fourth (the C3 Code launch) is disclosed via the company's IR press-release feed because product launches are typically not 8-K-disclosed. Each is also surfaced individually as a card on the C3.ai Financials post-FY events panel; the arc is what this page adds — reading them as one integrated leadership-driven repositioning rather than four discrete announcements.
