Why the engine matters more than the rebalancer
Tamarac is a strong rebalancer. Where it might hit a ceiling is when you need the system to think across multiple dimensions at once.

Frequently asked questions
Is it easy to switch?
Yes. Vise handles the heavy lifting so you can get up and running fast. Our AI-powered onboarding agents prefill documents using your custodian and CRM data, and our team manages the technical setup end to end. Enterprise firms typically complete onboarding in about 3 months, compared to 12-24 months with legacy platforms. You'll have a dedicated team guiding you through every step.
Do I have to migrate all accounts at once?
No. You can move accounts over at your own pace. Vise builds a personalized tax plan for each client with separate short-term and long-term gain budgets, so every transition is optimized to minimize tax impact. Many firms start with a handful of accounts, see the results, and expand from there.
What about my existing models?
Bring them. Vise's Strategy Center lets you import your existing investment models and manage them with versioning, effective dating, and full audit logs. You can set firm-level defaults and allow client-level overrides. If you're running a strategy we don't already have in our universe, we'll work with you to add it.
Which custodians does Vise support?
Vise integrates with Fidelity, Schwab, BNY Mellon, BNY Pershing, Goldman Sachs, Raymond James, and Altruist, with more on the way. All integrations support real-time data feeds for cash and positions, straight-through trade processing, and automated daily reconciliation.
How is Vise different from Tamarac?
Tamarac is a rules-based rebalancer; Vise is optimization-based. Rather than stacking individual rules, Vise solves for the best trade across tax, risk, turnover, and tracking error at once, and sees look-through ownership of funds to avoid needless gain-realizing swaps.
Does Vise replace Tamarac's rebalancing?
Vise runs portfolio construction, rebalancing, and tax management on one optimization engine, with daily tax-loss harvesting and wash-sale avoidance coordinated across the household. Firms often move tax-sensitive and high-net-worth books to Vise for optimization depth a rules-based rebalancer can't match.
¹ Ratio of total losses harvested by Vise Long Short (145/45) vs. a long-only direct index across all market environments, in Vise simulations 06/2005–06/2025. Benchmark: Morningstar US Large-Mid Cap 1000; net of transaction costs and 1.0% financing, not net of management fees. Hypothetical, backtested performance; not indicative of future results.
² Daily harvesting reflects Vise's internal backtest for US Large Cap direct indexing (daily single-stock tax-loss harvesting; 37% short-term / 20% long-term tax rates). Monthly (2.84%), quarterly (2.64%) and annual (1.64%) harvesting come from Vise's internal harvest-frequency study using the same methodology. The chart illustrates these annual rates over the selected time horizon. The shape of each line — including the timing and depth of any decline — is illustrative and does not represent a specific historical period or a backtested return path. Methodologies and tax assumptions may differ between figures. For illustrative purposes only. Simulated and backtested performance does not reflect actual client accounts and does not guarantee future results. Tax treatment varies by individual circumstances; consult a qualified tax professional.
