Working With OSK-SBI

The road is full of hurdles — we’re here to help you hop over a few. As investors, we strive to be your biggest supporters, to open doors and roll up our sleeves when you need it. While great companies are often the exception to the rule, this is generally how we operate.

We invest from Series A all the way up to pre-IPO.

We’re based in Kuala Lumpur but invest across all of Southeast Asia. Just about from Japan to Malaysia.

We are sector agnostic, with particular interests in enterprise software, fintech, healthcare, education, impact and sustainability, as well as emerging technology.

We’re happy to lead, co-lead rounds or participate in rounds, with $2m-$5m checks and generally reserve some capital for follow on rounds.

Continued growth of the middle-class and expanding household incomes in developing economies, digitalization and automation become increasingly necessary for all companies to maintain a competitive edge – just to name a few.
