Cornerstone Offshore Group

What Cornerstone Offshore Group does

Cornerstone Offshore Group, operating through its Singapore-incorporated parent Cornerstone Offshore Pte Ltd, is a privately held offshore and subsea solutions provider founded in 2017. The company's core offering is project-based subsea services supported by a fleet of Remotely Operated Vehicle (ROV) systems — the Chinooks ROV, the Argos ROV, and the newly added Mako LIC ROV (introduced July 2025) — delivered to offshore energy operators and marine contractors for subsea inspection, maintenance, and operational support. The technology stack is domain-specialized rather than software-driven, with no APIs, SDKs, or AI components disclosed.

The company operates a three-country Southeast Asian footprint through wholly-owned regional entities: Cornerstone Offshore Pte Ltd in Singapore (headquarters at 311 Old Birdcage Walk #02-05), Cornerstone Offshore Sdn Bhd in Kuala Lumpur (Wisma UOA II, Jalan Pinang), and PT Cornerstone Offshore Nusantara in Bandung, Indonesia. Its go-to-market is primarily direct enterprise engagement complemented by event-driven positioning — including participation in IEW 2025 (where the company hosted the Malaysian Deputy Prime Minister), sponsorship of regional competitive events such as the IAME Asia Final in Macau, and corporate communications through its LinkedIn presence and news blog.

The revenue model is professional services: fees generated from ROV operations and related subsea engineering engagements, with no publicly disclosed pricing, contract terms, or customer logos. The company received SME500 2024 Trademark Authorised recognition. In July 2025, the company signed a Memorandum of Understanding with Satu Borneo Sdn Bhd, formalizing a strategic collaboration in the regional offshore value chain. No revenue, headcount, funding, ownership detail, or leadership profiles are publicly disclosed.
