A Legacy Of Purpose And Progress.

Callus Family Office exists to transform responsible ambition into lasting progress. Rooted in Estonia’s tradition of technological ingenuity, we unite capital and expertise to build a legacy defined by our values and the impact family wealth can create.

Our story began with a conviction that technology could serve as a force for social and environmental good. Over time, that conviction evolved into a disciplined investment philosophy that balances innovation, sustainability and generational stewardship.

We See Capital As a Tool.

Its purpose is not accumulation, but enablement of progress, opportunity and balance between economic advancement and environmental responsibility.

To Deploy Financial And Intellectual Capital In Ways That Create Enduring, Measurable Value For Future Generations.

Callus Family Office pursue this mission through:

Direct investment in technology-driven enterprises with the potential to improve or protect essential systems.

A dedicated philanthropic focus on environmentally biodiverse restoration and regenerative models of growth.

Multi-generational wealth management and governance that ensures continuity of purpose and stewardship.

Callus Family Office Is Guided By Three Operational Principles:

Callus Family Office Concentrates On Sectors Where Technology Meets Purpose. Our Investment Lens Prioritises:

Fintech innovations improving financial access and integrity structures

Proptech and digital infrastructure supporting sustainable urban development

Each investment narrative is tied to measurable outcomes and transparent governance standards. Impact themes and portfolio monitoring are managed cohesively by our internal investment team in Tallinn, with advisory input from trusted partners where necessary.

Our Structure Reflects Both Simplicity And Focus.

From Tallinn, our small, interdisciplinary team combines investment professionals, philanthropic advisors and family representatives working under unified leadership.

Strategic advisors contribute on matters requiring specialist insight, such as environmental finance, succession governance or data infrastructure, ensuring that each decision aligns with both purpose and prudence.

Governance frameworks ensure continuity through clear delegation of authority, periodic portfolio review and adherence to family charters that articulate intergenerational intent.
