Every sleeve. Every lot. Every morning.
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%
Built for two kinds of firms
RIAs that want to rebalance better
Every sleeve in a UMA handled its own way, cash and tax budgets that actually hold, and a plain-language reason behind every trade. Straightforward to adopt, without rebuilding your operation.
Aggregators, TAMPs, and enterprises
Everything in the core, plus role-based home pages, bulk onboarding and portfolio migrations, firm-wide model dispersion, staged transitions at scale, and daily reconciliation across custodian feeds.
The account, the way the engine sees it
One household's UMA: every sleeve, how it's handled, where it sits against target, and what needs a decision.
Product screen. Simulated data.
Every sleeve on its own terms
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.
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.
Model dispersion, measured at the sleeve
When one 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 its model's 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 that proposes. Rules that decide.
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.
From onboarding to the morning queue
Legacy portfolios, moved inside a tax budget
Selling everything on day one realizes the whole gain. Fractive builds a staged path instead, and every legacy holding gets a plan and a disposition window.
- Each tax year held to its own budget
- Change the budget and the path redraws
- A proposal stays a draft until someone approves it
Product screen. Simulated data.
Every trade explains itself
Each proposed trade says why this security, what else was considered and why it cost more, and which rules it was checked against.
- Do-not-sell lists and lowest-cost lots
- Short-term gains avoided where possible
- Always inside the tax budget
Product screen. Simulated data.
The custodian wins, and the screen says so
Every account is compared with the custodian each morning. Breaks are sorted by type, with what each one blocks and how it gets fixed.
- Fixed by posting the missing event, never by editing a holding
- A sale that never reached the custodian is blocked on day two
- Normal trading stops until the break is cleared
Product screen. Simulated data.
A home page that's already done the work
Each role starts the day on what needs a decision: drift, blocked accounts, and harvest opportunities, explained in plain English.
Bulk onboarding
New accounts mapped to a best-fit model and placed on a single- or multi-stage path set by your own tax thresholds.
Portfolio migrations
Move a book from one model to another, with overlap, tax cost, and the transition path visible before anything trades.
Tax-aware harvesting, measured honestly
Harvest within the rules, then see the benefit as estimated, scenario, or unknown. Never guessed as zero.
Built differently
Open architecture
Works with the custodians, model providers, and order management systems firms already use, rather than replacing them.
Simple by design
Clear screens, sensible defaults, and settings that read like the investment policy behind them. Built for operations teams and advisors, not only quants.
Lean by design
A modern architecture without the cost structure of legacy platforms, and economics that reflect it. Easy to start with, and it grows with you.
