Direct indexing and tax overlay for omnibus trust platforms. No re-papering required.

Run direct indexes, tax-managed proprietary models, and household tax management inside your existing omnibus, trust accounting, and block-trading setup. Alphathena doesn't require you to move a single account.

Your clients are seeing tax-managed portfolios from firms you compete with. Your structure is what's holding you back.

Trust companies trade omnibus for good reasons: One block trade, clean allocation into trust accounting, and a fiduciary process your committee controls.

But nearly every other direct indexing and tax overlay provider is built as a manager that needs its own fully disclosed account at the custodian. Plus, a conversion is long, expensive, and usually ends with an outsourced manager instead of your firm in control.

Handing order flow to a discretionary manager outside your fiduciary process leaves you responsible for trades you didn't place

Running omnibus for most accounts and fully disclosed for tax-managed ones creates redundancy, with two sets of procedures

A fully disclosed manager means re-papering accounts and client agreements for every new account you want to tax-manage

Alphathena lets you offer tax-managed, personalized portfolios without changing how your accounts are structured.

Alphathena is software you run inside your existing setup. Accounts stay in the omnibus, you don't re-paper any accounts, and your team maintains the order flow. Athena AI prioritizes and surfaces work across your entire book, and your people remain in control of investment management and decision-making.

Build

Create custom direct indexes from any of 2,000+ indexes or ETFs, run tax overlay on your own house models, and hold third-party SMAs as sleeves.

MANAGE SLEEVES

Alphathena creates virtual sleeves within a single trust account. Your client can hold a large-cap direct index, your proprietary value model, a fixed income allocation, and more all in just one account with one custodial relationship.

CONNECT

Connect to the trust accounting, trading partners, and portfolio management systems you already run. If we don't have a connection, we'll scope the integration upfront and commit to a delivery date before you sign.

Case studies

ICR Partners grows 50% year over year after adding Alphathena's platform to support its work with trust companies.

“We had recurring scenarios, like portfolios with a lot of embedded gains from mutual funds and ETFs, that were difficult to help clients with. Our provider required liquidation, which meant large taxable gains and obviously that wasn’t an attractive option to clients. With Alphathena, we can keep those holdings in the portfolio and make it work.”
