- The person who keeps it all moving and organized
Stoneriver Capital provides this leadership on a fractional basis, without the permanence of a full-time executive.
When Structures Grow Complex,
Operations Demand Experienced Leadership.
Every engagement is led by Richard Silberberg, who provides hands-on management of special projects, administrative work, and day-to-day operations while drawing on a trusted network of specialists as needed.
Every Enduring Structure is Built in Layers.
Stoneriver Capital provides the operational core that connects them all. Share your operational priorities to determine whether we are the right fit.
Complexity Outpaces Existing Operational Structures.
Additional residences, new legal entities, significant liquidity events, and international relocations can create demands that exceed existing administrative capacity.
Does this sound familiar?
Three Phases. Seamless and Intentional Execution from Day One.
Map What Exists
We inventory every entity, account, advisor, property, policy, and recurring obligation, then show you plainly where the structure is thin and what it would cost to leave it there.
Four to six weeksClose the Gaps
Governance, compliance calendar, consolidated reporting, internal controls, systems, and the bench of specialists to support them. Built to your scale, not a template's.
Three to six monthsOperate It
Ongoing operational leadership at whatever cadence the structure needs: a standing day each week, monthly oversight, or full engagement through a transition.
