Built to hold,
not to trade

Sounio Holdings exists for a single purpose: to acquire and hold meaningful equity positions in technology and software companies that we believe in deeply. We are a passive holding structure with a long-term orientation, backing founders and businesses that build things that endure.

How we invest

We look for businesses built on strong foundations, then give them the one thing most capital can't offer: time.

I

Concentrated Positions

We take fewer, larger positions in companies we understand deeply. Our conviction is reflected in our commitment, not diluted across a scattered portfolio.

II

Enduring Software

We back technology and software companies that solve real problems. Products with strong retention, clear value propositions, and the potential to compound over decades.

III

Patient Capital

We are structured to hold indefinitely. No fund cycles, no forced exits. This permanence allows us, and the companies we back, to think in years, not quarters.

The columns still stand at the edge of the Aegean. Not because they were built to impress, but because they were built to last.

A longer view

Named for the ancient promontory where sailors once navigated by the temple on the cliff, Sounio Holdings takes the same long view. Scanning the horizon for what endures, and building positions meant to stand the test of time.
