INTERPOSE INVEST · WEALTH MANAGEMENT

The managed-portfolio experience advisors actually want.

The wealth-management side of Interpose Invest is a complete advisor-driven stack — model rebalancing, direct indexing, tax-aware and household rebalancing, GIPS performance, and AUM billing — behind white-label advisor and client portals on your custody.

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 on your custody.

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.

05

Report & bill

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

Institutional-grade PM your customers can't get from custody alone.

Capabilities legacy PM platforms charge extra for — or don't support at all — are first-class features on a modern, unified data model.

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 the advisor sets 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.

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.
