Keystone Apex is a Singapore-domiciled investment and operating holding. We anchor a coordinated platform of subsidiaries — combining AI products and managed delivery under institutional governance and APAC-scale execution.
Two focused subsidiaries. One coordinated platform. Each company is operationally independent and commercially distinct — Keystone holds the equity, sets the governance, and underwrites the institutional contracting layer.
Shared services, managed delivery and BPO automation for global operators. Engineered in the Philippines, governed for the world. Operates across NAM, EMEA, ANZ and APAC.
Subsidiary detail →A proprietary sovereign agent stack built end-to-end: Phoenix the autonomous agent runtime, AI Box the on-prem sovereign appliance, yForce the architecture & delivery team. Engineered for institutional buyers who need AI without cloud dependency.
Subsidiary detail →Keystone is not a services vendor and does not compete with its subsidiaries. The holding plays three structural roles — capital, governance, and master contracting — that the operating companies cannot, and should not, play themselves.
Keystone holds the equity in each operating company, allocates capital across the platform, and serves as the single counterparty for institutional investors, partners, and strategic capital.
Singapore domicile provides the contracting, compliance and audit posture that enterprise and institutional buyers require — independent of where delivery occurs.
For multi-subsidiary engagements — AI products plus managed operations under one accountable contract — Keystone serves as the prime, with operating companies as named delivery entities.
A clean two-tier structure. The holding sits in Singapore. Operating subsidiaries are domiciled and run from Manila. Equity, governance and master contracts flow through the holding; delivery, talent and operations stay with the operating companies.
A snapshot of the operating platform. These are aggregate group figures across both subsidiaries — measured, not modelled. Detailed metrics by subsidiary and engagement type are available under NDA for institutional enquiries.
Three lanes route to the right counterparty: investor relations, enterprise and government, or media and partnerships. Keystone responds within one business day, Singapore time.
