The Circle

Those who have built, backing those who will.

Operators, founders and investors who have led their fields, now backing the next generation.

The 6igma Circle

Operators who have built market leaders across Asia — and now open doors for the next generation

Many of our Limited Partners and advisors are entrepreneurs and executives who have spent decades building businesses in banking, consumer brands and technology, and scaling them across borders. Others bring deep experience in policy. Together, they offer what capital alone cannot: judgment earned through direct experience.

For founders, the Circle turns a plan into a path: access to customers in Vietnam, introductions to banks and distributors across Asia, and practical guidance for entering the next market.

Today’s founders become tomorrow’s members — a circle that carries capital, knowledge and trust from one generation of builders to the next.
