Who Owns SentinelOne Company?

Who owns SentinelOne?

SentinelOne went public in June 2021 (NYSE: S) after raising about $1.2 billion at a roughly $10 billion fully diluted valuation. Founded in 2013 in Tel Aviv and Mountain View, it now serves over 11,000 customers and surpassed $600 million ARR by FY2025.

As a widely held public company, SentinelOne combines founder and insider stakes with large institutional holders and active board oversight; ownership shifts since the IPO shape strategy, M&A appetite, and governance. See SentinelOne Porter's Five Forces Analysis for competitive context.

Founders Tomer Weingarten and Almog Cohen launched SentinelOne in 2013 (initially Sentinel Labs); early ownership followed standard Israeli‑U.S. security startup patterns with founders holding significant but undisclosed stakes that diluted through venture rounds.

Founders

Tomer Weingarten (CEO) and Almog Cohen co‑founded the firm in 2013, bringing product, security and research expertise from prior roles in Toluna, Carambola and Check Point.

Early name

The company began as Sentinel Labs and rebranded to SentinelOne as it commercialized its endpoint and XDR technology across U.S. and Israel markets.

Pre‑seed ownership norms

Typical early-stage Israeli‑U.S. security startups allocated 20–35% aggregate founder ownership pre‑seed, vesting over four years with a one‑year cliff; SentinelOne followed comparable structures.

Option pools

Standard seed-stage option pools of 10–15% were created to attract GTM and R&D hires in the U.S. and Israel as the company scaled.

Early investors

Initial angel and seed backers comprised cybersecurity angels and seed funds in Israel and the Bay Area; by 2014–2015 institutional names included Data Collective DCVC, UpWest and Granite Hill, later joined by Tiger Global in growth stages.

Legal terms

Early legal frameworks reportedly used NVCA‑style terms: four‑year vesting, ROFR/Co‑Sale rights, and protective provisions on major corporate actions to protect investor interests.

As SentinelOne progressed through Series A–C and into growth funding, founder stakes diluted in line with venture norms while founders retained influence via board seats and leadership roles rather than special voting stock.

Key points on early ownership

Founders, governance and investor mix shaped SentinelOne’s early ownership structure and post‑seed evolution.

• Co‑founders Tomer Weingarten and Almog Cohen founded the company in 2013 and led product and research directions.
• Precise initial equity splits were not publicly disclosed; industry norms suggest founders held 20–35% pre‑seed collectively.
• Seed rounds commonly created a 10–15% option pool to attract senior hires across the U.S. and Israel.
• Early institutional backers included Data Collective DCVC, UpWest, Granite Hill and later Tiger Global; investor rights followed standard NVCA terms.

Key financing events from 2015 through the 2025 fiscal year reshaped who owns SentinelOne: venture rounds (2015–2019), late‑stage financings and the June 30, 2021 IPO, followed by institutional rotation and index inclusion through 2024–2025, produced a broadly dispersed institutional ownership base with no controlling shareholder.

Public filings (Form 10‑K and DEF 14A through 2024–2025) show a transition from concentrated venture ownership to dispersed institutional and index ownership; governance influence diluted among many holders and strategy oriented toward sustainable ARR growth, margin improvement, and partner ecosystems.

Ownership milestones and implications

Key ownership shifts moved control away from early VCs toward diversified institutional holders, reducing single‑investor governance leverage and aligning incentives with long‑term public investor expectations.

• 2015–2019 venture rounds built the cap table and option pool, diluting founders
• 2021 IPO created broad free float and brought large mutual fund holders
• 2022–2024 institutional rotation raised passive ownership to double‑digit combined percentages
• 2024–2025 filings indicate no controlling shareholder; largest holders under 10%

As of 2024–2025, SentinelOne's board blends executive leadership and independent oversight, led by Co‑founder and CEO Tomer Weingarten alongside independent directors with finance and technology experience to steward corporate governance and shareholder interests.

Board committees are chaired by independent directors (Audit, Compensation, Nominating & Governance), aligning with standard public‑company practices and proxy advisory expectations.

Board composition and voting dynamics

SentinelOne maintains a one‑share‑one‑vote common stock structure with governance driven by institutional holders and proxy advisors; no dual‑class or super‑voting shares are disclosed in recent filings.

• Board includes a mix of insiders and independents, with financial and technical expertise
• VC‑affiliated directors from Insight Partners, Third Point Ventures, Tiger Global held past roles; representation has rotated post‑IPO
• No public high‑profile proxy contests in 2024–2025; governance debates center on compensation, operating leverage, and capital allocation
• Say‑on‑pay and committee oversight numerical outcomes aligned with typical S&P/tech peer ranges

Institutional ownership remains the primary determinant of voting power: as of mid‑2025 major institutional shareholders include mutual funds and asset managers holding aggregate stakes commonly reported in SEC filings; proxy advisory recommendations (ISS/Glass Lewis) influence contested votes and say‑on‑pay outcomes — for more on the company background see Brief History of SentinelOne

SentinelOne ownership shifted from concentrated venture stakes toward broader institutional and passive holders in 2023–2025, driven by secondary sales, index inclusions, and improving operating metrics that attracted long‑only investors.

Institutional ownership percentage rose materially between 2023–2025, with passive funds accounting for a growing share of float while venture and early investors continued limited, staged sell‑downs.

Ownership dispersion

Secondary sales and index inclusions shifted SentinelOne ownership toward institutions and passive funds, reducing concentrated venture stakes.

Financial inflection

ARR scaling past $500M in 2024 and exiting FY2025 near/above $600M supported greater long‑only investor interest and index eligibility.

M&A and capital focus

Activity centered on tuck‑ins and partnerships in identity/cloud security; capital has favored growth over large buybacks through 2025.

Insider and governance trends

Founder sales used 10b5‑1 plans, insider ownership remained modest, and governance has moved toward the profile of other public cybersecurity peers.
