The portfolio operating system
Portfolios built for each client.
At scale.
Zeton lets investment firms run every account as its own portfolio, under its own rules, from one platform, without the cost that has kept personalization for the largest clients.

The demand
Every client wants a portfolio built for them.
Investors now expect the personalization they get everywhere else, and advisors increasingly win clients on it, especially on taxes. Customization has stopped being a perk for the largest accounts. It is becoming the baseline.
- 78%
- of affluent investors say it is important that their accounts are customized to their specific situation.
- 69%
- say it is important that their provider helps them reduce their tax bill.
- 47%
- of financial advisors already offer tax planning, and see it as a differentiator.

The gap
The industry’s own research names the gap.
Cerulli benchmarked nine process solutions for customized portfolios, drawing on interviews with 26 industry executives. Three show the thinnest deployment. Each is, underneath, an optimization run for every household or every account.
That is exactly what Zeton is built to do.
Asset location optimization
What Cerulli found“Limited deployment with many platforms defaulting to a single account management structure due to complexity or supervision concerns.”
A portfolio can hold a whole household, with every member’s rules checked together.
In development Tax-aware asset location across a household’s accounts.
Multi-account rebalancing
What Cerulli found“Very limited automation deployment; engineering frequently exceeds proprietary capabilities.”
Every account is optimized under its own constraints at each rebalance. The system proposes; a person releases it.
Tax budgeting
What Cerulli found“Rare instances of automated multi-year budgeting processes in place; firms are commonly struggling with implementation.”
In development Lot-level harvesting and multi-year transitions, sequenced against a stated tax budget.

The answer
One platform for the whole portfolio lifecycle.
Zeton runs every account as its own portfolio, from the first idea to the next rebalance. The system does the heavy lifting; your team makes the decisions.

Why we can
Why the 1,000th account costs almost nothing.
Zeton is what firms use. Aqua, the engine beneath it, is what lets us serve every client individually and still run like software. It reads the machine it runs on and reuses work across the many similar portfolios a firm runs every day.
5.78×
more client accounts served per machine
Per-account workload: 1,000 client accounts at full machine load, on three cloud machine types, against the same workload without Aqua.
95%
of the work reused across similar portfolios
Across 1,000 accounts the solver met just 49 distinct problem shapes, and reused 95.1% of its setup.
Identical
results, to the last digit a computer stores
Agreement with the reference within 2.4 × 10⁻¹⁶. Aqua changes how fast the answer arrives, never the answer.
Zeton runs on Aqua.
Aqua runs on what you already own.
Figures measure computation (time, cost and numerical accuracy), not investment returns. The gain applies where Zeton’s optimizer runs the solve.
Who we serve
One platform, three ways in.
We start with independent RIAs and the platforms that serve them, and grow with the firms that are bringing personalization to every client.
Under $100B
Growth-oriented boutiques
Independent RIAs, IBDs and bank trusts
Outsource
Reached through the TAMPs, custodians and model platforms they already rely on. One platform running Zeton carries every firm on it.
$100B to $1T
Emerging enterprise
Regional broker-dealers, banks and the largest RIAs
Partner and integrate
Home offices that will not build this themselves, and cannot outsource it wholesale, need a process-solution partner inside their advisor platform.
Over $1T
Enterprise scale
The largest wirehouses and broker-dealers
Build or buy
They have built their own platforms. What they lack is a lower cost per optimization as personalization moves down-market: Aqua, licensed inside their platform.
Personas: Cerulli Associates, Customized at Scale (October 2025), Exhibit 9. Single-family offices and hedge funds are served directly and sit outside this retail-wealth frame.
