Who we serve

Built for firms with more than one custodian and a private book.

Stonebook is for RIAs and family offices that typically run $75 million to $2 billion across two to twelve custodians. If your ops team rebuilds the book in a spreadsheet before every pack or exam, this is who we built it for.

Multi-custodian RIAs

Schwab, Fidelity, Pershing, and a few more, each sending files in its own format.

  • One household book across every custodian
  • Late or failed files flagged before a pack goes out
  • Unlimited seats for ops, compliance, and principals

Single-family offices

A public book at the custodians and a private book of partnerships, co-invests, and real assets.

  • Private marks printed with the date you entered
  • Entity and ownership tags for trusts and LLCs
  • Stale marks labeled, never rolled forward

Multi-family offices

Several families, each with its own entities, custodians, and reporting habits.

  • Households and entities grouped the way you already report
  • Quarterly packs for every family from the same book
  • Look-through exposure against the limits you set

Firms preparing for an exam

Compliance teams that need the record, not a binder built the week before.

  • Prior as-of books kept read-only
  • Recon flags and sign-offs kept with the book
  • Packs pulled for a named household in one place

A strong fit if you

  • Hold assets at two or more custodians
  • Keep private holdings in a separate spreadsheet
  • Send quarterly household packs
  • Want your firm's limits, not a vendor's score

Probably not a fit if you

  • Hold everything at a single custodian with no private assets
  • Need trading, rebalancing, or billing software
  • Want a platform that makes investment recommendations
