Look first. Then open the same book yourself.

Every panel below is a real capture of a seeded sandbox tenant — the same 19-client, 42-account firm a signup hands you, free, in about thirty seconds. Nothing here is a mock-up, and nothing below asks for your calendar.

  1. One book across four custodians

    6 of your 42 seeded accounts live at Schwab, Fidelity and Pershing in aggregated custody, sitting in the same portfolios as the natively-custodied ones. The same strategy, the same drift bands and the same rebalancer span all of them — which is the entire argument for an overlay, made on screen instead of in a slide.

  2. Three years of lots, one harvest waiting for you

    The seeded book carries three years of backdated history through the real fill path: genuine holding periods, realized gains in two tax years, a real wash sale, and harvestable losses in both terms. A harvest run sits at ORDERS_GENERATED when you arrive — approving it, or picking it apart lot by lot, is the first ten minutes of the trial.

  3. Firm models with real analytics behind them

    3 of the 4 seeded portfolios are backed by firm models — the fourth carries direct weights on purpose, because both shapes are first-class. Model analytics, drift measurement and the trading desk's by-model grouping all resolve against the same records.

  4. A practice in motion, not a database at rest

    Every advisory client arrives with a meeting history — briefings, transcripts, action items — plus review cadence the dashboard actually reads: overdue reviews, clients needing contact, cash flowing in and out this month. Today's meeting is deliberately left unbriefed, so the first AI briefing you see is one you generate.

  5. Sign in as your own clients

    4 seeded people can sign in to the client portal — one advised, three self-directed — and the portal derives each experience from the shape of their accounts, exactly as it does for a real firm. Their credentials are listed on your advisor dashboard; open one in another browser and evaluate both sides of the product from one signup.

That was the tour. The product takes thirty seconds more.

Everything above exists in your own tenant the moment you sign up — the same book, plus the parts a page like this can't show: the rebalancer generating real orders, the billing preview pricing a quarter line by line, and API keys you mint yourself.
