Episode notes
Structured Multifamily Office Model
- Future Family Office evolved into a multifamily office serving six families with ~18 staff and three collaborating units: family office, wealth & investment, and tax & compliance.
- Lee Mayberry emphasizes cross-team collaboration to deliver nimble ad-hoc support and consistent compliance work for complex family needs.
Organic Growth From Paying Bills
- The office began by paying simple bills and gradually expanded as other partners asked to join, morphing into a full financial arm over time.
- After a liquidity event in 2008–09 the families pursued direct private investments and the office supported VC fund structures and direct entities.
Capture Time-Series Data Early
- Start by recording time-series investment data now, even using simple tools like ShareSite and Excel, to create a reliable history for future upgrades.
- Migrate to a sophisticated platform later (Lee used Addepar) once you have good backfilled data to cut reporting time from hours to minutes.
