Radstone Capital Group

Radstone Capital Group
Private Capital. Purposeful Deployment. Specialized Domains.
Radstone Capital Group is a privately held investment holding group with principal activities in Malaysia and strategic interests in Australia and the United States. The Group is focused on private credit, with a specialization in the invoice factoring segment. Leveraging deep sectoral expertise, disciplined credit analysis, and structured deployment frameworks, Radstone functions as a trusted platform for institutional and select high-net-worth investors seeking access to this underserved asset class.
Through carefully structured partnerships with asset managers, family offices, fund managers, and private equity firms, Radstone deploys capital into high-quality, real-economy factoring opportunities—offering risk-mitigated exposure to short-dated trade receivables. The Group maintains a strict institutional orientation and does not solicit retail investors.
In parallel, Radstone is actively building a portfolio of healthcare and medical technology assets across its three core markets. These investments span primary care networks, dental care and dental tourism, and next-generation med-tech solutions—particularly AI-enabled diagnostic and monitoring technologies.
Radstone Capital Group stands at the intersection of disciplined private credit investing and targeted healthcare innovation—two sectors where precision, governance, and long-term value creation converge.

Private Credit – High-Yield, Asset-Backed Financing through Invoice Factoring
Creating Sustainable Value Through Short-Term Receivables Financing

Investment Structure
Risk Management
Liquidity
High-quality receivables from vendors supplying to creditworthy obligors—public listed companies, GLCs, and multinationals. These receivables deliver above-market returns with lower risk profiles than traditional unsecured lending.
Capital is deployed through structured factoring arrangements where invoices are purchased at a discount and collected at full value upon maturity. This provides investors with legal title to the underlying assets and contractual rights against obligors, creating multiple security layers.
All transactions undergo rigorous vendor and obligor due diligence with legal assignment, corporate guarantees, and controlled accounts. Our risk framework evaluates over 20 risk factors, emphasizing obligor payment history and vendor performance. This approach has maintained near-zero defaults since inception.
With 30-90 day transaction cycles, this strategy enables frequent capital recycling and minimal market correlation. Unlike traditional private credit with 3-5 year lockups, our factoring strategy offers quarterly liquidity windows with short notice periods.
The Group operates in Malaysia's invoice factoring market through Special Purpose Vehicles designed to enable collaboration with counterparties as required.  In a region where bank financing remains bureaucratic and risk-averse, we provide direct liquidity to businesses while generating stable, above-market yields. 
Factoring remains undervalued in private credit, particularly in emerging markets. With our quality invoice pipeline, compliance frameworks, and robust origination capability, Radstone is positioned for scalable growth. Our strategic relationships with major corporations in Malaysia and across Southeast Asia provide privileged access to premium transaction flow.
Southeast Asia's factoring market continues to expand due to growing trade volumes and retreating traditional lenders from SME financing. This working capital gap creates sustainable opportunities for Radstone while maintaining disciplined underwriting standards.

Medicare Capital Group leads the Group's innovation-led healthcare investment platform, focusing on transformative medical technologies that combine clinical efficacy with commercial scalability. Our core investment is in Opum Technologies, a US based healthtech firm redefining musculoskeletal care through intelligent diagnostics.
By investing in Opum, Medicare Capital Group is championing a new paradigm in healthcare—where data meets design, and patient outcomes drive value creation.
