Tax alpha your advisors can prove.

The tax engine
One plan for the whole household, not one account at a time.
Four tiers, one household plan
- Cash first, then high-growth equities in Roth, tax-efficient equities in taxable, and bonds and REITs in traditional IRAs.
- Your model's weights never change. Only where each class is held does.
- Location efficiency scores how close the household is to its plan, as it stands and as far as it can get.
- Held-away, minors' and closed accounts are tracked but never traded.
Tax alpha you can show, in dollars
- Each household's tax alpha in dollars and basis points, at its own federal bracket, net investment income tax and state rate.
- Asset location and this year's harvesting added up, then set beside the fee from your fee schedule.
- 10, 20 and 30-year projections of what the plan is worth over time.
- Roth conversions priced bracket by bracket, and sent to Wealthbox as a task.
Every account
$0.00
difference between Mirella and the custodian. Every account ties out to the penny, and automated tests check the math on every release.
The rebalancer
Rebalance in Mirella, not iRebal.
Trades that know the tax cost
- A class needs rebalancing when it drifts by the lesser of 5 points or 20% of its target, the same rule on every screen.
- A rebalance never realizes a net short-term gain across the household.
- When the wash-sale rule blocks a buy, Mirella buys an approved replacement fund, and swaps back when that costs no tax.
- Do-not-sell and do-not-trade restrictions hold a position in place, and the plan works around it.
Cash holds
Hold cash in an account until a date for a withdrawal. The rebalancer raises it and never spends it.
Raise or invest cash
Run a full rebalance, raise cash only, or invest cash only.
Your minimums
Set trade minimums by security type. Fractional shares by default.
Approvals
Only admins, or members they name, can approve a household's trades.
Tax-loss harvesting
Harvestable losses found with each day's data, and the wash-sale rule checked everywhere.
A daily scan of every taxable lot
- Each day's Schwab data is scanned for lots with a loss worth taking, $500 or more by default.
- Every buy in the household is checked, IRAs included, over a 30-day window that is never shortened.
- Each suggestion names a replacement fund that keeps the household invested in the same asset class.
- Dismiss one with a reason, and it comes back after 90 days or if the loss grows by a quarter.
AI
AI that works from your numbers, not its guesses.
The Daily Brief
- Your day on one page: today's meetings from Google Calendar, with one-click meeting prep.
- Opportunities across your book: losses to harvest, households outside their band, and excess cash.
- Reviews that are due, with the review-request email already drafted.
- Open Wealthbox tasks, recent notes and this week's birthdays.
The Data Agent
- Ask about any household in plain English, from a chat page or from any client screen.
- It runs the engine for you, including what-if changes, and answers with the engine's own results.
- Meeting prep in one question: recent activity, open action items and portfolio opportunities.
- Each surface uses the model that scored best in our benchmarks for that job.
Guardrails built in
- It never does its own math. Every number comes from Mirella's engine in the same answer.
- It sees exactly what the advisor asking is allowed to see, and nothing more.
- It never suggests selling a position you have restricted.
- It drafts Wealthbox notes and tasks, but nothing is posted until an advisor clicks.
- It places no orders. Trading has its own approval path.
- It never sees a client's date of birth or the text of your Wealthbox notes.
- The AI providers keep nothing: zero data retention, with data collection turned off.
Built on what you use
Works with Schwab and Wealthbox, not instead of them.
Schwab, connected
Positions, tax lots and cash load from Schwab's daily files, and approved orders go back to Schwab.
Wealthbox, both ways
Mirella reads households, contacts, notes and tasks, and writes notes, tasks and contact changes back.
Book linking
Mirella proposes which Schwab accounts belong to which Wealthbox household, graded by confidence, for you to confirm.
Shared or separate books
Let advisors share one book, or give each one only their own clients. Admins still see the whole firm.
Model portfolios
Upload your models from a spreadsheet and assign one to many households at once.
Fee schedules
Tiered and marginal schedules, calculated to the cent, with a firm standard and per-household choices.
Risk questionnaire
Define your own questionnaire and record a suitability profile for each household.
Needs attention
Each household shows what to do next: harvest candidates, contact differences, beneficiary gaps and more.
Clean book
Departures, dependents who have outgrown a household, and a data audit keep the book accurate.

Security and control
Built for a regulated business.
Checked on the server
Every page and every request checks who is asking and what they may see. Roles come live from your firm's member list.
Sensitive fields encrypted
Dates of birth and tax IDs are encrypted with AES-256-GCM, and each firm's integration keys are stored encrypted.
A full audit trail
Every change to a household, setting, restriction or approval is recorded, and kept for seven years.
Approvals that fail closed
If Mirella cannot confirm who may approve, nobody can. A trade never goes out on a guess.
A safe demo book
Demo mode shows only a sample household and blocks real client data, so you can train and present safely.
No passwords stored
Sign-in is handled by a dedicated identity provider. Mirella never stores a password.
How we build
Built with a firm, not for a market
Every feature ships against a real advisor's daily work, starting with Bright Road Wealth Management.
Deterministic, not approximate
Tax alpha and asset-location math that ties out to the penny, every time.
For advisors, not their clients
Mirella's software serves the people managing the money, not the people it belongs to.
Built for RIAs managing $50M to $1B on Schwab and Wealthbox, whether your advisors share one book or each keep their own.
We're onboarding a small number of firms before launch.
Built with Bright Road Wealth Management
Bright Road is Mirella's first client: an institutional wealth manager running a four-tier tax-location engine across every household they manage. What we build for them ships first, tested against real portfolios and real advisors.
