# Peak XV Partners Seed Investment Discloses Investment at Horizon Quantum Holdings with 20.3% Stake

Peak XV Partners Seed Investment disclosed a 20.3% stake in Horizon Quantum Holdings Ltd., equal to 6,468,999 Class A Ordinary Shares. The position stems from a March 16, 2026 business combination that converted its prior holdings in Horizon Quantum Computing Pte. Ltd. into Horizon Quantum Holdings shares, and the firm reported the stake in a Schedule 13D filed on July 9, 2026. The sizable holding positions the investor to influence future corporate actions while operating under post-merger lock-up terms.

**Investor Intent**

Peak XV Partners Seed Investment says it holds the shares for investment and could buy more or sell depending on its assessment of the company. It explicitly notes it could support “an extraordinary corporate transaction, such as a merger, reorganization or liquidation,” and also reserves the right to “increase or decrease its holdings” at any time.

Most shares remain under a lock-up that lasts up to 24 months after March 16, 2026, though Horizon Quantum waived restrictions on about 9% of each non-affiliate holder’s shares. The investor also secured registration rights, and Horizon Quantum has already filed and cleared a resale registration to facilitate potential future sales.

**Investor's Background**

Peak XV Partners Seed Investment is a Mauritius-organized investment vehicle that acquires, holds, and disposes of company interests for investment purposes. It is associated with Peak XV Partners, a venture platform focused on early-stage and growth investments across India and Southeast Asia. The group backs technology-driven companies and has a track record of long-term, hands-on support of portfolio founders.
