May 2026 · A partnership proposal

The native alts
operating layer for VestmarkONE.

Be the preferred SubDoc and redemption partner inside the UMA chassis your customers already trust. Power the products you lean on partners for today — natively, with an economic component for Vestmark.

Build. Access. Operate.
01What we heard
02Three capabilities
03The wedge — and what we don't touch
Section 1 · Capabilities

What we heard.

Three things from the Nov 21 call shaped this proposal. Everything that follows is built around them.

Priority · #1

The general priority is streamlining the advisor experience.

Rob Klapprodt · Corporate Strategy Officer
Green light

If there's an experience that is simpler, easier to operate, with an economic component for us, we'd love to understand that — that would be interesting.

Rob Klapprodt · Corporate Strategy Officer
We also heard: Vestmark is not a TAMP, has run alts on-platform for 15 years, and is explicitly neutral on partners. The narrow surface where Vestmark leans on other providers today — SubDoc processing and redemption handling — is the exact surface where Aqua is purpose-built. This deck is a proposal for being your preferred default on that surface, with economics that work for Vestmark.
Section 1 · Capabilities

Three capabilities, one operating layer.

Aqua + AIX is a single platform that solves the SubDoc-heavy alts surface end-to-end. Wealth advisors transact through Aqua; asset managers and sponsors deliver through AIX. Both feed VestmarkONE.

Build

White-label product.

Your customers can stand up their own private fund-of-funds, SPVs, or feeder structures inside VestmarkONE — Aqua handles the operational backend, you handle the chassis and the relationship.

Access

The network.

~100 fund managers on the platform — Blackstone, Apollo, JLL, and the rest of the usual suspects, plus boutique offerings. Extend Vestmark's manager marketplace into SubDoc-heavy product without lifting your team.

Section 1 · Capabilities

What we do — and what we don't.

You've run alts on VestmarkONE for fifteen years. We're not here to retell that story. We're here to take one specific operational headache off your plate.

Aqua's wedge

SubDoc-heavy product.

The surface where Vestmark explicitly leans on partners today. We handle every operational step, advisor never leaves VestmarkONE.

  • Drawdown PE, private credit, real assets — anything that requires a sub doc
  • Subscription workflow — digital forms, intelligent pre-population, 0% NIGO target
  • Redemption operations — orchestrate across fund admins, TAs, and your iBoard
  • Post-trade lifecycle — capital calls, distributions, K1s, quarterly reporting
  • Fund admin + TA coordination — service agreements with managers, data ingested directly
Already native to Vestmark

Where we stay out.

You handle these natively today and they work. We don't need to touch them, and we won't pretend otherwise.

  • Interval funds — handled on VestmarkONE natively
  • Evergreen structures — same
  • Custody reconciliation back to your iBoard
  • UMA sleeve management + overlay implementation
  • Manager marketplace contracting for publics
  • Advisor-facing portfolio management and trading
The honest version: Aqua is not an alts platform replacement. It's a workflow layer for the one surface where SubDocs, redemptions, and post-trade ops require what Mike called "bringing the advisor back into the fold." We make that fold invisible.
Aqua
Section two

Where we
plug in.

We sit on top of VestmarkONE for SubDoc-heavy products. Your stack stays in place — Aqua is an addition that unlocks a new lane of product without your customers ever leaving the platform.

Section 2 · Where we plug in

How Aqua sits on top of VestmarkONE.

No rip-and-replace. Your UMA chassis, iBoard, custody reconciliation, and overlay management all stay in place. Aqua wraps the SubDoc + lifecycle surface and routes everything back into your existing systems.

Today · Handoffs out

Vestmark stops where the SubDoc starts.

The typical SubDoc-heavy flow for a Vestmark customer today — the advisor hits a wall and the work routes to another provider, with email-driven coordination back to your iBoard.

Stage 1 Advisor identifies allocation inside VestmarkONE Vestmark
Stage 2 ⤵ Advisor pulled out — routed to external SubDoc workflow Handoff
Stage 3 SubDoc processing, NIGO loops, e-signatures Other provider
Stage 4 Capital calls, distributions, K1s — managed externally External
Stage 5 ⤴ Manual reconciliation back to iBoard via email + spreadsheet Handoff
Stage 6 Position appears in VestmarkONE — eventually Vestmark
Two handoffs out, two handoffs back. Every SubDoc-heavy product means the advisor leaves the platform, and your iBoard reconciles work it didn't see in real time.
With Aqua · One flow

Same chassis. One workflow.

Aqua becomes the SubDoc + lifecycle layer inside VestmarkONE. The advisor doesn't leave. Your iBoard sees positions in real time. No new vendors for the customer, no rip-and-replace for you.

SubDoc-heavy product, native to your platform

Apollo and KKR shown here as illustrative — drawdown structures previously routed externally now sit on the same shelf as your model portfolios and evergreen alts.

Section 2 · Where we plug in

Models with alts inside.

Rob's conviction product path — models, and models of models — is where Aqua matters most. The moment a model portfolio includes a SubDoc-heavy sleeve, the advisor is back in the fold. Unless we're underneath it.

Example · Diversified UMA model

A Vestmark model with a 15% alts sleeve.

Public equities and fixed income run through your overlay manager. The alts sleeve is half evergreen (you handle natively) and half drawdown (powered by Aqua).

  • Advisor sees one model in VestmarkONE
  • Allocation rebalanced inside your UMA
  • SubDoc + redemption ops fully handled by Aqua
  • Vestmark earns sub-advisory bps on the whole model

The advisor sees one model. The overlay manager keeps doing what it does. Aqua handles the SubDoc-heavy slice underneath. Models-of-models with privates inside finally works without pulling the advisor out of VestmarkONE.
Section 2 · Where we plug in

Your questions, answered.

Three specific questions from the Nov 21 call. Direct answers — including where the answer is "not today."

Asked by Rob

What's in your data model — redemption windows, fund-level data, post-trade events?

We integrate directly with fund administrators and transfer agents via signed service agreements — data comes from canonical sources, not derived from custodian feeds. Redemption windows, capital call schedules, distribution events, K1 timing all flow into the platform live. Your iBoard can pull from us in whatever shape works best for your reconciliation flow.

Live data, source-of-truth, API-ready
Asked by Rob

For interval funds — do you maintain redemption windows there?

Honest answer: not our focus today. Interval funds are a consideration but not a priority. Our wedge is SubDoc-heavy product, which interval funds aren't. You already handle interval funds natively on VestmarkONE — we'd extend coverage there only if it becomes a Vestmark priority, and only because the partnership warrants it. We won't pretend interval funds are core for us when they aren't.

Not today — extendable on demand
Asked by Mike

Secondaries for these investments — what's your perspective?

Genuinely hard problem. The information asymmetry between buyer and seller means most "secondary platforms" offer offensively low prices and don't get used. We're seeing new entrants try to be backup liquidity providers with real-time valuation partners — but the BREIT/tender-offer dynamic Mike flagged is the real risk surface for evergreens, not drawdowns. We're not building secondaries ourselves. We are positioned to plug in whoever wins that lane.

Hard problem · we're plumbing-ready
Section 2 · Where we plug in

How we compare to your current partners.

You already integrate with other providers for SubDoc-heavy product — and you've told us you're agnostic between platforms. Here's where we'd land as the preferred default when the client is ambivalent.

SubDoc workflow
Custom-built per fund — best-in-class, 0% NIGO target
Investor-passport model — standard digital flow

Posture toward Vestmark
Vestmark is the platform · we're the layer underneath
Their own platform · integration partner

We're not asking to replace your current providers overnight — they're real platforms serving real volume. We're asking to be the preferred default for the SubDoc-heavy products where Vestmark, the advisor, and the economics all benefit from a partner that operates as a layer rather than a platform.

Section three

Partnership economics
+ next steps.

Three integration flavors, a clear economic framework, and a concrete first move — designed around the "economic component" you asked for on the Nov 21 call.

Section 3 · Partnership economics

Three flavors of partnership.

Three ways Aqua can plug into Vestmark, ordered from lowest commitment to deepest. Each carries an economic component — we'd shape the specifics with Rob and the team.

01

Marketplace listing.

Lowest commitment

Aqua appears inside Vestmark's manager marketplace as a preferred SubDoc + redemption partner. Advisors who reach SubDoc-heavy product can choose Aqua. When client is ambivalent, you steer.

EconomicsRev share on AUM serviced

03

Co-development partnership.

Deepest commitment

Joint roadmap on alts-inside-models, shared product cycles, mutual exclusivity on defined surfaces. Aqua and Vestmark engineering teams operate against a coordinated backlog. Strategic, not transactional.

Phase 1 — live by Q4 2026.

A concrete first move. One Vestmark BD client, one fund family, one SubDoc-heavy product line — proven end-to-end before we widen scope. IFG, already on Pershing (which we integrate with), is a natural candidate.

Now → June

Working session

Rob, Corey, Mike + Rohan, Joe, Sara. A working session at Wakefield or Philly — pick a candidate BD client, pick a candidate fund family, pick the integration flavor. You leave with an MOU shape.

July

Pilot scope lock

Joint scoping with the chosen BD client. Aqua handles the customer onboarding. Vestmark handles platform integration on your end. Specific success metrics defined — NIGO rate, time-to-funded, advisor satisfaction.

Single integration flavor — Marketplace or White-label
Aug–Oct

Build + integrate

API integration between Aqua and VestmarkONE. SubDoc workflow embedded in advisor experience. iBoard reconciliation tested with live data. Compliance and ops walkthroughs with both teams. First product wired end-to-end.

Live · and scale

First Aqua-powered SubDoc-heavy product live inside VestmarkONE at one BD client. Real volume, real NIGO data, real economics. Decision point: which other BD clients next, which integration flavor to standardize on.

Ready when you are.

Joe sent a "let's set time for a deeper dive" note on November 24. The offer still stands — and the proposal in this deck is the shape we'd bring to that conversation. Pick a date, pick a flavor, and we go from there.
