What we bring

Relationships, reach, and cross-border depth.

Petra Investors & Co. is a London-based investment advisory firm established in August 2024, with active engagement in Seoul and mandates spanning Europe, the Middle East, and Asia. We operate through a senior network of advisors with deep sector and geographic expertise, focused on situations where direct relationships and cross-cultural fluency make a material difference to the outcome.

Korea is a particular area of depth. We maintain active relationships with Korean institutional investors, corporates, and market participants — giving clients access to a market that is difficult to navigate from the outside.

What we advise on.

We work on a select number of mandates at any time, across M&A, market access, and cross-border strategy.

Cross-Border M&A Advisory

Strategic advice on cross-border transactions — identifying potential counterparties, navigating commercial complexity, and supporting negotiations across different markets and cultures.

Capital Markets Strategy

Advising companies and funds on how to position themselves for engagement with capital markets — including narrative, messaging, and identifying the right audiences for their stage and sector.

Market Entry Advisory

Strategic guidance for companies entering new markets — mapping the landscape, identifying relevant partners, and developing a considered approach to commercial entry.

Institutional Outreach Strategy

Advising fund managers and companies on how to approach and communicate with institutional audiences across Europe, the Middle East, and Asia-Pacific.

Healthcare & Life Sciences

Advisory for biotech and medtech companies on cross-border licensing, international partnerships, and strategic positioning in global markets.

The most valuable capital in cross-border work is not financial. It is the trust of people on both sides of the table.

That trust — across markets, languages, and cultures — is what Petra was built to carry.

People

Junghwa Oh is a Korea-born, London-based investment professional with over two decades of experience across financial markets, cross-border transactions, and international business development. Her combination of institutional finance, on-the-ground Korea experience, and global network underpins the work Petra does.

Most recently, she served as CEO of Infinitum Investors Group from 2022 to 2024, having joined the firm in 2019. In that role, she advised clients ranging from large conglomerates to early-stage companies on market access and strategic positioning across global markets, with a particular focus on high-growth sectors in Korea — including technology, biotechnology, healthcare, and consumer. Before that, she spent close to a decade at the European Bank for Reconstruction and Development (EBRD) in London, working on cross-border transactions in both equity and debt, and successfully raising the EBRD's first equity fund of EUR 350m. Before joining the EBRD, she was a Reuters correspondent based in Seoul, covering macroeconomics and bond markets. She holds an MBA from London Business School and a law degree from Korea.
