One book of record, however many custodians you run.

The complete managed-account stack — models and drift, tax-aware and household rebalancing, direct indexing, GIPS performance and AUM billing — behind white-label advisor and client portals, unified across every custodian your firm holds.

From new client to billed and reported.

The full managed-account lifecycle — onboarding through billing — as REST endpoints and a white-label portal, on the same event stream as every position and order.

01

Onboard

Add a client and their accounts — taxable, IRA, Roth, 401(k) — grouped into a household across whichever custodians hold them.

02

Assign a model

Apply a model or portfolio sleeves; set drift bands, tax constraints, and rebalancing cadence per account.

03

Monitor drift

Multi-dimensional drift — cash, asset class, sector, factor, household — is tracked continuously against the model.

04

Rebalance

Generate tax-aware trade proposals across the household; approve, then route to execution as block orders, or export them to trade at your custodian.

05

Report & bill

GIPS performance, client statements, and idempotent AUM billing — all branded to your firm.

The capabilities you were told to buy separately.

Direct indexing, tax overlay, household coordination and alternatives are normally a second vendor, a third contract and a nightly file. Here they are first-class features on one unified data model, on one event stream.

Direct Indexing

Clients own the underlying securities — not a fund share — enabling factor tilts, ESG exclusions, and position-level tax-loss harvesting at fractional-share precision.

Tax-Aware Rebalancing

Every rebalance is evaluated against the tax ledger pre-trade: short vs. long-term lots, wash-sale detection, and realized-gain budgets you set per account.

Household Rebalancing

Rebalance taxable, Roth, IRA, and 401(k) as one coordinated unit — tax-inefficient assets located in tax-deferred accounts, growth equity in taxable, automatically.

GIPS Performance & Attribution

Time-weighted (Modified Dietz, chain-linked) and money-weighted (IRR) returns, composites by mandate, blended benchmarks, and contribution/attribution analysis.

AUM Billing

Tiered fee schedules with breakpoints, household aggregation, per-account overrides, proration, and idempotent billing runs — invoices in PDF + JSON, branded per firm.

Alternatives, Native

Private equity, hedge funds, interval funds, and real assets with NAV valuation, capital-call tracking, and illiquidity constraints — in performance and household views.

Construction analytics on the model, not in a spreadsheet beside it.

Sector and asset-class exposure, Herfindahl concentration, effective position count and top-holding weight — computed on the model itself, so the concentration you are about to assign to forty households is visible before you assign it.

The CRM reads the portfolio, because it is not a separate system.

Meetings, briefings, transcripts and generated client presentations draw on live positions and performance — no export, no nightly sync, no reconciling two versions of the same household.

An AI co-pilot for the advisor — with a human always in the loop.

Drift monitoring surfaces accounts outside their bands, proposes tax-aware rebalances, and flags concentration risk and tax-loss-harvesting opportunities — turning routine portfolio maintenance into a review-and-approve workflow.

High-risk actions always require human approval — the regulatory floor is enforced structurally, not by policy alone. Pre-meeting briefings are AI-generated when a key is configured, with a templated fallback otherwise.

The Rivera Household has drifted 4.8% overweight US equity. A tax-aware rebalance harvests $2,140 in losses and stays inside the realized-gain budget.

Your advisors' workspace. Your clients' window.

Two portals, both fully themed to your brand and domain — the advisor's daily driver and the client's view of their wealth.

Where this stands today

The advisor portal is the daily driver and is in use now. On the client portal, SEC Marketing Rule 206(4)-1 requires net-of-fee performance shown with at least equal prominence, plus firm-configurable disclosure text on every performance surface — both are in build and land before any end client of yours sees a screen. We'd rather tell you that here than have your CCO find it in a demo.

Built for a book, not a demo.

The rebalancing engine is designed and load-tested for real advisory scale — thousands of accounts, hundreds of securities per model, coordinated at the household level.

10K accounts

Rebalanced in a single run, load-tested

500 securities

Per model, at direct-indexing scale

Household-first

Tax and asset location across accounts

Block orders

Aggregated execution, or exported to trade at your custodian

One ledger under the advisor and the investor.

Wealth management shares the same event-sourced services as the self-directed experience, so every managed trade and fee reconciles to a single auditable ledger — regardless of which custodian the assets actually sit at.

AI Back-Office

Drift, proposals, briefings — human-approved

Load your export and see your own drift.

Start in a sandbox firm with a seeded book, then send the position and lot export you already download. We scope a first go-live in weeks, not quarters — then you are looking at your own drift and your own harvest candidates, not a canned demo firm.
