Global wealth platform built by acquisition · 40+ family offices, $5B–$70B AUM each

My role: Wealth management product lead

M&A: Consolidating 40+ family offices into one operating model

A private-equity-style roll-up only pays off when the acquisitions run as one. I have led product work to remove the operational and technology debt each acquisition brings.

The situation

Every office arrived with its own portfolio system, custodians, fee schedules, billing habits and onboarding process. Across 40+ offices that meant seven different portfolio systems, 100+ custodians, duplicated work, uneven controls and revenue slipping through the gaps.

What I did

  • Moved offices off seven portfolio management systems used across the group onto Addepar, migrating historical holdings, historical performance, client data and fee and billing data into Addepar and Salesforce.
  • Supported custodian consolidation: Charles Schwab is now the dominant custodian in the operating model, with the group consolidating toward Schwab and Fidelity and a limited set of custodians for the remaining business.
  • Built a central billing function: standard fee schedules, one calculation method and a single collection process.
  • Reviewed wealth management agreements against the future fee model and sized the impact for every client and advisor before anything changed.
  • Designed the future processes across Salesforce, Addepar and internal tools, with billing, revenue and onboarding controls built in, then set up and trained the central teams that run them.

Custodians

100+ custodians, consolidating to Schwab and Fidelity

Schwab is the dominant custodian in the operating model. Fidelity is the second core relationship, and a limited set covers the rest.

Before: fee per officeAfter: one schedule

Billing

One fee model, sized before launch

Standardised fee schedules and billing data from every office, then modelled the fee and revenue impact client by client.

Onboarding & controls

Controls designed in, not bolted on

Simplified how new offices join and added billing, revenue and onboarding controls that stop leakage.
