Top 8 Masttro Alternatives for Family Offices in 2026

Last updated: October 27, 2026.

Quick Answer

The best Masttro alternatives in 2026 are Aleta (best overall, an AI-native total wealth management platform with an open API, a two-way MCP layer, 4 to 8 week implementation, and pricing from $1,000 per month), Asset Vantage (best for accounting and reporting on one ledger with published pricing), Addepar (best for institutional analytics), FundCount (best for offices running pooled vehicles with outside investors), Archway (best for an outsourced back office), Eton Solutions AtlasFive (best for a family office ERP), Landytech Sesame (best for investment data validation), and Asora (a first system for a small office with a listed portfolio).

Masttro is one of the established platforms in the category, and family offices evaluate alternatives for three structural reasons: implementations that have run far beyond the 12 to 14 weeks the vendor states, a closed architecture with no published open API or MCP layer, and premium pricing that is quoted rather than published. This guide compares the eight strongest alternatives on the criteria that decide these evaluations: implementation time, pricing model, AI architecture, and whether the office can get its data out.

Key Takeaways

• Aleta is the best Masttro alternative for most family offices in 2026: the same consolidation across liquid, illiquid, and passion assets, on an AI-native total wealth management platform with a documented open API, a two-way MCP layer, and the Data Cube, live in 4 to 8 weeks from $1,000 per month.

• Masttro publishes more than 700 direct custodian feeds, 400 or more clients, and a fixed annual license not tied to assets under management, and states a typical implementation of 12 to 14 weeks; evaluations Aleta has participated in have observed far longer.

• Masttro Intelligence, launched October 16, 2025, added Documents AI, Alternatives AI, and an Intelligence Assistant inside the platform; Masttro publishes no open API and no MCP layer, so an office cannot run its own AI agents on the data.

• Implementation across the alternatives runs from 4 to 8 weeks (Aleta) to 3 to 6 months (FundCount, Asset Vantage), 6 to 9 months (Archway, Eton Solutions), and 6 to 12 months (Addepar).

• Three of the eight publish entry pricing: Aleta from $1,000 per month, Asset Vantage from about $30,000 per year, FundCount from $35,899 per year; Addepar prices on assets under management from about $70,000 per year (reported).

What Is Masttro?

Masttro is a wealth technology platform founded in 2010, headquartered in New York with offices in Zurich and Monterrey. The platform consolidates liquid and illiquid investments, liabilities, and passion assets into a single view of total net worth for ultra-high-net-worth families, family offices, RIAs, and private banks.

The company raised $43 million in growth equity in March 2023, led by FTV Capital with participation from Citi Ventures. Masttro publishes more than 700 direct custodian feeds, 400 or more clients across 40 or more countries, and uses a fixed annual license that is not tied to assets under management, quoted rather than published. In July 2025 it partnered with Arch for K-1 and capital call workflows, and on October 16, 2025 it launched Masttro Intelligence, an agentic AI framework with Documents AI, Alternatives AI, and an Intelligence Assistant.

Masttro is typically shortlisted for complex multi-jurisdiction ownership structures and markets itself on security and custodian coverage. The trade-offs that push offices toward alternatives are structural: implementation weight, a closed architecture, and premium pricing.

Why Do Family Offices Look for Masttro Alternatives?

Four reasons come up consistently in the evaluations Aleta has taken part in and in the vendor's own published material.

1. Implementation timelines

Onboarding Masttro is a major project. The vendor states a typical implementation of 12 to 14 weeks, and its own published client example is a $1 billion office that loaded 200 or more alternatives in three months or less. In evaluations Aleta has participated in, complex multi-entity structures have taken far longer than the stated window before the platform was fully operational.

2. Closed architecture and data portability

Masttro is built as an all-in-one suite. That is a strength if you want one system for everything, and a constraint the moment you want your consolidated data to flow into a general ledger, a BI tool, or your own AI stack, because Masttro publishes no open API and no MCP layer. Moving data out, whether for daily workflows or an eventual migration, is harder than moving it in.

3. Opaque premium pricing

Masttro markets a fixed-fee model that is not based on AUM, but the actual cost is custom-quoted, difficult to benchmark before a formal proposal, and sits at the premium end of the market. Enterprise wealth platforms commonly run from $50,000 to $250,000 or more per year once implementation and ongoing data operations are included.

4. AI added on top rather than built in

Masttro Intelligence, launched on October 16, 2025, added Documents AI, Alternatives AI, and an Intelligence Assistant. It is an agent layer placed on an architecture designed in 2010, and it operates inside the same closed suite, so the intelligence is the vendor's rather than the office's. The question for buyers in 2026 is no longer whether a platform has AI features. It is whether the data layer was designed for machines to consume: a documented API, structured data access, and an MCP layer that lets your own AI tools query your wealth data and act on it; the explainer on what MCP is and why it matters for family offices sets out the test.

The 8 Best Masttro Alternatives in 2026

1. Aleta: Best Overall for AI-Native Total Wealth Management

Aleta is an AI-native total wealth management platform for family offices, headquartered in New York with offices in Aarhus and Bangkok, built on more than 20 years of total wealth reporting expertise. It monitors more than $100 billion in assets and processes more than 1 million transactions a year across more than 100 custodian and bank integrations, each built and maintained by Aleta rather than rented from an aggregator, and it was named Best Consolidated Reporting at the WealthBriefing Awards 2026 and Best Data Provider at the Family Wealth Report Awards 2026.

Against Masttro the overlap is the consolidation itself: liquid and illiquid holdings, multi-entity and multi-currency ownership structures with a wealth map and full look-through, alternative assets with capital call and distribution processing, and white-labeled portals. The separation is what happens to the data afterward. On Aleta it sits in a built-in investment general ledger, so every return traces to its transactions, and it leaves the platform three ways the office controls: an open API documented at docs.aleta.io, a two-way MCP layer for the office's own AI agents, and the Data Cube for Excel, Power BI, and Tableau. Private markets paperwork is handled by Aleta Intelligence, the platform's suite of AI tools, which turns each capital call, K-1, NAV statement, or distribution notice into a booked ledger entry, while a dedicated Data Management Team keeps the feeds reconciled every day.

Strengths:

• AI-native architecture: Built for AI agents and family office principals and professionals as equal users of the system. Aleta Intelligence in the platform core, with an open API and a two-way MCP layer so the office's own AI tools read and act on reconciled data.

• Live in 4 to 8 weeks, against months or quarters.

• Data ownership: the Data Cube and the API and MCP carry consolidated data into BI tools, the general ledger, and AI agents and assistants, and the office can leave with its data at any time.

• Principal-first design on the same platform that serves the CIO reconciling positions across entities and currencies.

• Pricing from $1,000 per month, based on platform scope and services, never on assets under management; SOC 2 Type II certified.

Limitations:

• Offices that want a heavy outsourced service layer or lifestyle administration inside the suite will find Aleta leaner by design; the books live in the ledger the office chooses, connected through the API.

• Monte Carlo simulations cannot be carried out directly in the platform, but in the family office's own AI assistant based on reconciled data through Aleta's MCP.

Verdict

Choose Aleta for Masttro-grade consolidation with open data, published pricing, a 4 to 8 week implementation, and AI built into the foundation. The head-to-head is at Masttro vs. Aleta.

2. Asset Vantage: Best for Accounting and Reporting on One Ledger With Published Pricing

Asset Vantage grew out of the family office of the UNIDEL technology group in 2011 and is headquartered in Stamford, Connecticut, with offices in Singapore, Mumbai, and Pune. Its native dual-entry general ledger is the custody, investment, and accounting book of record at once, which is why it carries more than 400 families in over 10 countries and more than $400 billion tracked across over 5,000 activated data feeds. The price list is public and entity-based, starting around $30,000 per year in the US with no AUM component; onboarding is quoted on time and materials, and 3 to 6 months is the usual range (estimated). The platform is SOC 2 Type II certified and lists no AI or MCP capability among its integrations.

Strengths:

• A single ledger feeding the custody, investment, and accounting books, which removes the reconciliation between them.

• A public, entity-based price list, which is the transparency Masttro does not offer.

• Multi-entity and multi-currency depth proven across more than 10 countries.

Limitations:

• Built for the finance team; a principal looking for a phone-first overview will find it dense.

• Nothing published on AI document processing or MCP.

• No fixed onboarding window; the timeline is whatever the time-and-materials scope produces.

Verdict

Choose Asset Vantage if accounting precision across many entities is the priority and you want a published price. A common pattern is Asset Vantage underneath for the books and Aleta on top for the family's total wealth view; Asset Vantage vs. Aleta walks through it.

3. Addepar: Best for Institutional-Grade Portfolio Analytics

Addepar, founded in 2009, is the analytics standard for RIAs, private banks, and very large family offices, with $9 trillion on platform across more than 1,400 firms in roughly 60 countries. Performance attribution, risk decomposition, and scenario modeling are the deepest in the category. The costs of that depth are an AUM-based price (single family office entry reported from about $70,000 per year), implementations of 6 to 12 months, and a steep learning curve that often puts a dedicated Addepar administrator or an external consultant between the office and its reports. Its AI story is acquired and layered (Arcus, the Addison assistant, the Addepar Data Exchange) on a data schema from 2009; the API is public, and the Claude-only MCP connection was still a waitlisted beta in October 2026.

Strengths:

• The deepest performance and risk analytics in the category, proven at very large scale.

• A large custodial network and a documented API.

• An institutional brand.

Limitations:

• A price that moves with the market because it is set on assets under management.

• Half a year to a year to implement, then an administrator or consultant to keep the reports running.

• An analyst's tool first; the principal gets the output rather than the platform.

Verdict

Choose Addepar if institutional analytics depth is the deciding factor and you have the team and budget to operate it. A family office leaving Masttro for a verified total wealth view the principal can open, with IRR, MOIC, and TWR in the platform and no AUM-based bill, lands on Aleta instead; the two are set side by side in Addepar vs. Aleta and the Addepar alternatives.

4. FundCount: Best for Partnership Accounting With Outside Investors

FundCount, built in 1999 for hedge funds and headquartered in Barbados since 2022 with offices in Boston, Toronto, Singapore, and Dubai, is the ledger-authority platform: reports are generated from the books, so there is no reconciliation between an accounting layer and a reporting layer. NAV by fund, class, series, and side pocket, master-feeder allocations, and GAAP and IFRS multi-book reporting come standard, which is exactly what an office needs when outside investors hold interests in vehicles it runs, and more than it needs otherwise. Single family office plans are published from $35,899 per year with digital transformation and hosting billed separately, implementations take 3 to 6 months, FundCount AI Assistant and AI Document Intelligence are recent and validated mainly by the vendor, and there is no documented open API.

Strengths:

• Partnership accounting depth and books-to-report integrity.

• Handles master-feeder and nested entity structures.

• Published entry pricing.

Limitations:

• Accountant-first interface; not designed as a principal-facing tool.

• No documented open API and no MCP layer.

• The fund machinery is paid for and unused without outside investors.

Verdict

Choose FundCount if your general ledger is the source of truth and you run pooled vehicles for outside investors. Without that structure, Aleta's built-in investment general ledger gives the office accounting-grade books on the portfolio with AI-native document processing and an open API on top, which is the comparison drawn in FundCount vs. Aleta and the FundCount alternatives.

5. Archway: Best for a Managed Back Office on One Ledger

Archway dates from 2002, spent 2017 to 2025 inside SEI, and has been owned by Aquiline since June 30, 2025 ($120 million), with the operational separation from SEI completed in August 2026. More than 550 families and over $850 billion sit on a single general ledger that serves as both the investment and the accounting book of record, with more than 200 report templates and in-house accountants who do the bookkeeping and the bill pay. That service model is the reason to choose it. The trade-offs are no native AI (alternatives documents flow through Canoe Intelligence since July 2024 and Arch since October 2025), a client portal rather than a dedicated mobile app, implementations of 6 to 9 months, and pricing typically between $80,000 and $150,000 or more per year (estimated).

Strengths:

• Investment and accounting books on the same ledger, with look-through built in.

• Accountants on staff who run the bookkeeping and the bill pay as part of the service.

• More than two decades in the segment and more than 550 families on platform.

Limitations:

• AI comes from partners (Canoe, Arch) rather than the platform, and there is no published open API.

• Half a year or more to implement, at an estimated $80,000 to $150,000 or more per year.

• The family's access is a branded portal rather than a dedicated app.

Verdict

Choose Archway for a managed services model with accounting-grade books. Offices that want a modern principal experience without a migration put Aleta above it in 4 to 8 weeks, as walked through in Archway vs. Aleta.

6. Eton Solutions AtlasFive: Best for an Integrated Family Office ERP

AtlasFive from Eton Solutions, commercialized from technology built inside the multi-family office Eton Advisors and based in Research Triangle Park, North Carolina, with an international headquarters in Singapore, spans more than 270 operational workflows: general ledger accounting, entity management, bill pay, document management, and client reporting in one system. Eton reports more than $1.4 trillion under administration for more than 1,050 families, advisory firms, and private equity firms (vendor figures), raised a $58 million Series C led by Navis Capital Partners in July 2025, and has added EtonAI, a Microsoft Fabric integration (May 2026), EtonAxis (November 2025), and EtonAlpha (February 2026). Entry pricing is reported around $150,000 per year and deployments typically run 6 to 9 months; neither is published.

Strengths:

• The broadest functional footprint in the category, including lifestyle administration.

• A single operational system of record with a meaningful services layer.

Limitations:

• Enterprise implementation timelines and cost.

• A vendor-managed pipeline into one BI ecosystem rather than an open data layer the office owns, so the office cannot point its own agents at the data.

• Heavy for offices that mainly need consolidation and reporting.

Verdict

Choose AtlasFive if you are consolidating the entire operation, not only the reporting. An office that mainly needs Masttro-grade consolidation with data it owns gets there with Aleta in 4 to 8 weeks at a fraction of an ERP rollout, as Eton Solutions vs. Aleta and the Eton Solutions alternatives show.

7. Landytech Sesame: Best for Investment Data Validation at Scale

Landytech, a London company founded in 2019 with teams in Paris and Pune, built Sesame around the investment team's workflow with validation as the core discipline: more than 500 custodian feeds and over 10,000 open banking sources, more than $250 billion under reporting, an AI agent it calls aLi, and a stated onboarding window of around three months for most single family offices (vendor figures). Pricing is not published.

Strengths:

• Strong data quality and validation across global custodians.

• Institutional reporting outputs for demanding investment teams.

Limitations:

• Reporting-first rather than principal-first; family members consume outputs secondhand.

• No published pricing; the aLi agent is recent and vendor-validated.

Verdict

Choose Sesame if validated investment data across many custodians is the primary problem and the investment team is the only user. Offices that want the same data rigor with a principal-ready view find it on Aleta, where a dedicated Data Management Team reconciles every feed daily behind a total wealth overview built for the family; the best wealth reporting software guide places the two side by side.

8. Asora: A First System for a Small Office With a Listed Portfolio

Asora, founded in 2021 in Dublin, is the entry-level option: nine net worth brackets published from about $900 per month ($1,300 per month for the $50 to 100 million bracket), add-on packs of 20 at $3,600 per year, a one-time implementation fee of 25 percent of the annual subscription, and unlimited users. Reporting stops at metric-level dashboards with no published risk layer, fund documents arrive through a Canoe Intelligence add-on because Asora has no AI of its own, no public API, and no BI connector. Asora markets a four-week setup; evaluations Aleta has participated in have observed 3 to 6 months.

Strengths:

• A clean interface and a full published price list.

• Unlimited users on every plan.

Limitations:

• Limited depth on alternatives, benchmarking, and performance analytics.

• Not built for complex multi-entity, multi-jurisdiction structures or professional investment teams.

• A light tracker, so growing offices face a second migration.

Verdict

Asora is too light to replace Masttro for an office with real complexity; treat it as a starting point for a small office with a simple portfolio. An office that wants Masttro's depth without Masttro's architecture skips the second migration and starts on Aleta, which prices from $1,000 per month on a flat, complexity-based fee; see Asora vs. Aleta and the Asora alternatives.

How to Choose a Masttro Alternative

Five questions decide most evaluations.

1. What Is Your Source of Truth?

If it is the accounting ledger, look at Asset Vantage, FundCount, Archway, or AtlasFive. If it is a consolidated wealth platform that feeds your other systems, look at Aleta, Addepar, or Sesame. If it is a simple total wealth view for a small office, look at Asora.

2. Can You Get Your Data Out?

Ask every vendor for a full data export and live API access during the demo, not after signing. Calculate the exit cost before you calculate the entry cost. This is where closed suites are most expensive.

3. How Does AI Access Your Data?

“We have AI features” is not the same as “your AI can use our data.” Ask whether the platform exposes a documented API, a structured data layer, and an MCP layer, and whether that layer is read-only or lets the agent act; of the nine platforms here, Aleta publishes all three and a two-way layer. If the only AI is a chatbot inside the vendor's interface, you are renting intelligence rather than building it.

4. What Does the Contract Say About Implementation?

Get time-to-first-report as a contractual milestone. Timelines only matter if they carry consequences: Aleta goes live in 4 to 8 weeks, Masttro states 12 to 14 weeks, and complex Masttro projects have run far longer in evaluations Aleta has participated in.

5. What Is the Five-Year Total Cost?

Compare license plus implementation plus data operations plus the staff needed to run the platform. AUM-based pricing compounds with your growth, fixed custom quotes hide escalation at renewal, and transparent SaaS pricing is the easiest to project.

Methodology and Sources

This guide is based on each vendor's published product and pricing pages as of October 2026, Capterra and G2 listings where they exist, funding and product announcements (Masttro's $43 million growth equity round led by FTV Capital in March 2023, its Arch partnership of July 17, 2025, and the Masttro Intelligence launch of October 16, 2025), and Aleta's direct experience in evaluations and migrations from incumbent platforms. Vendor claims are attributed as such, and figures Aleta has observed rather than vendors published are marked as observed.
