Fractive Labs builds open-architecture rebalancing and tax-transition software for TAMPs, managed account platforms, and wealth management firms that run many strategies inside a single client account. Sophisticated underneath, simple to use.
One account, five sleeves, rebalanced to target
Total drift 9.0%
A unified managed account holds very different kinds of money. Each sleeve type gets its own discrete handling, coordinated within one account.
Optimized against its benchmark at the tax-lot level, with tracking error and harvesting managed together.
Rules-based. Each manager's model is followed as delivered, with firm and account constraints applied on top.
Optimized toward the target portfolio, moving legacy holdings over time rather than all at once.
Advisor-directed, with its own guardrails, approvals, and firm-level oversight.
Handled by its own rules for maturities, cash flows, and reinvestment rather than simple percentage drift.
A discrete cash sleeve, separate from any manager's cash, for reserves, withdrawals, and fees, so cash needs are funded from the right places.
Counted in the household allocation and tax picture, so the managed sleeves account for them, without trading them.
One tax budget sits across the whole account, so every sleeve's trades draw against the same limit the advisor sets.
When one manager's model runs across thousands of accounts, each account's sleeve should earn close to what the model earns. Fractive compares every sleeve's actual return with the manager's model return, so you can see which accounts have strayed, by how much, and why: cash, client restrictions, tax decisions, or trade timing.
Illustrative data.
AI does the reading, watching, and explaining. A deterministic rules engine makes every trade decision, so results are repeatable and every trade traces back to the rule that produced it.
Finds opportunities, flags bad data, drafts explanations.
Applies each sleeve's rules and the tax budget. Same inputs, same trades.
Sent to the order management system the firm already uses.
Holdings and tax lots tracked for each sleeve within an account, reconciled daily against the custodian.
Strategic, tactical, cash, tax-harvest, and transition workflows, each matched to the sleeve it runs on.
Built to work with the custodians, model providers, and order management systems firms already use, rather than replace them.
Clear screens, sensible defaults, and settings that read like the investment policy behind them. Built for operations teams and advisors, not only quants.
Fractive Labs was founded by the co-founder and former CEO of a TAMP and managed account platform, with over 20 years of building and running rebalancing for independent advisors at scale.
