Mezzi: AI-Driven Advice for Full-Picture Portfolio Management

How Mezzi Works

Mezzi addresses the challenge of managing investments scattered across multiple accounts by offering a unified, actionable portfolio view. Using read-only access through Plaid and Finicity, Mezzi securely connects to your accounts, including brokerage, 401(k), IRA, HSA, and others. Importantly, it doesn’t require asset transfers - your holdings remain exactly where they are.

Once linked, Mezzi consolidates all your account data into a single, easy-to-navigate dashboard. Its AI processes this data to provide insights into your portfolio's allocation, fees, tax efficiency, and risk exposure. Mezzi highlights opportunities for improvement, but you retain control over implementing changes directly through your broker. This advice-only approach sets Mezzi apart from robo-advisors like Betterment or Wealthfront, which charge 0.25%–0.40% in annual fees and require transferring assets. Mezzi, on the other hand, operates on a flat subscription fee starting at $299 per year, while keeping your money untouched.

Mezzi's Key Features

Mezzi's value lies in its ability to offer a complete view of your portfolio, which is especially useful for investors with accounts spread across multiple institutions. According to a 2022 FINRA Investor Education Foundation study, over 60% of U.S. investors manage investments across two or more financial institutions. Without aggregation, it can be difficult to fully understand your portfolio's risk, fees, or allocation.

Mezzi delivers four essential tools to address this challenge:

• Unified portfolio view: Mezzi brings all your accounts together in one dashboard, breaking down your holdings by asset class, sector, and geography for a clearer picture of your investments.
• Tax optimization guidance: The platform helps identify tax-loss harvesting opportunities, warns you about potential wash sale risks, and advises on the best placement of assets between taxable and tax-advantaged accounts. For instance, a high-income investor in the 32% federal tax bracket might reduce their tax burden by moving a high-yield bond fund from a taxable brokerage to a traditional IRA, while maintaining the same risk profile.
• Retirement planning tools: By analyzing your connected accounts, Mezzi projects retirement timelines based on real data - not generic inputs. It factors in contributions, withdrawals, fees, and allocation to suggest strategies that could help you retire sooner.
• X-Ray overlap tool: By examining the underlying holdings of ETFs and mutual funds, this tool identifies overlapping stocks, helping you avoid unnecessary risk and redundant fees.

These features give investors the clarity they need to make informed decisions about their portfolios.

Security and Fiduciary Standards

Mezzi takes security and fiduciary responsibility seriously. As a Registered Investment Adviser (RIA) with the SEC, it operates under a fiduciary duty, meaning it’s legally required to prioritize your best interests.

When it comes to security, Mezzi ensures your data is protected at every step. It never accesses your login credentials directly. Instead, Plaid and Finicity use bank-grade encryption and tokenization to establish secure, read-only connections. This ensures Mezzi cannot make trades, transfer funds, or alter your account settings. The platform also supports Apple login for added privacy and adheres to a strict no data-selling policy.

For those managing wealth across multiple institutions, these security and fiduciary measures aren’t just added perks - they’re essential for trusting a platform with access to your full financial picture.

Sharesight: Performance Tracking and Reporting

Sharesight stands out as a platform dedicated to clear, data-based portfolio tracking, steering away from AI-driven advice.

How Sharesight Works

Sharesight operates as a cloud-based portfolio tracker, automatically importing your holdings and transactions. This automation ensures that total returns, dividend income, and portfolio value are updated continuously, removing the need for manual adjustments. Since it's cloud-based, you can access real-time updates from any device, making it easier to manage multiple accounts and stay on top of your investments.

Sharesight's Key Features

Sharesight provides a detailed view of your portfolio's performance by calculating total returns, which combine both price changes and dividend income. This gives you a more complete picture of how your investments are doing.

Its dividend tracking feature automatically records payouts and highlights the impact of reinvested dividends on long-term growth.

Another standout feature is benchmarking, which lets you compare your portfolio's performance against relevant market indices. This comparison can help you evaluate whether your returns are influenced by market trends or specific investment choices.

Sharesight also simplifies tax reporting, especially for investors with international portfolios, by offering tools designed to meet various global requirements.

Regional Focus and Tax Reporting Limitations

While Sharesight excels in international tax reporting, it has limited features for U.S.-specific needs, such as tracking wash sales. This makes it more suitable for investors outside the U.S. who require comprehensive global tax tools.

Mezzi vs Sharesight: Feature-by-Feature Breakdown

Account Coverage and Aggregation

Mezzi connects to a wide variety of U.S.-based accounts, including individual and joint brokerage accounts, 401(k)/403(b) plans, traditional and Roth IRAs, HSAs, and bank accounts. Using secure, read-only connections via Plaid and Finicity, it consolidates these accounts into a single, unified household view - no asset transfers required.

Sharesight, however, focuses primarily on investment portfolios. It supports importing trades from brokers or via CSV uploads and offers multi-account tracking. But it doesn’t integrate U.S. bank accounts or retirement accounts into a broader household balance sheet. For instance, someone with a Fidelity brokerage account, a Vanguard 401(k), and an HSA would see all accounts combined in Mezzi’s dashboard. Sharesight, on the other hand, would only track the brokerage account and any manually imported data.

Next, let’s look at how each platform handles performance tracking and analytics.

Performance Analytics and Benchmarking

Sharesight provides detailed performance reporting, including annualized returns, dividend income, capital gains, currency impacts, and comparisons against benchmarks like the S&P 500. This level of detail appeals to those who enjoy digging into the numbers themselves.

Mezzi takes a different approach by tying performance metrics to your personal financial goals. Instead of focusing on raw data, it offers insights aimed at helping you make progress toward your objectives.

This difference in focus leads to contrasting methods for handling tax-related issues.

Tax Optimization and Reporting

Mezzi and Sharesight diverge significantly in their approaches to tax management. Mezzi focuses on proactive strategies, while Sharesight emphasizes retrospective reporting.

Mezzi actively identifies tax-loss harvesting opportunities throughout the year, alerts you to potential wash sales across all linked accounts, and provides asset location recommendations. For example, it might suggest holding high-yield bonds in an IRA while keeping tax-efficient ETFs in a taxable account.

Sharesight, meanwhile, generates after-the-fact tax reports, such as capital gains summaries and dividend income breakdowns, which can be exported in CSV or PDF formats.

Feature	Mezzi	Sharesight
Tax-loss harvesting guidance	Identifies opportunities year-round	Not available
Wash sale monitoring	Proactive, cross-account alerts	Limited or manual
Asset location advice	Offers recommendations	Not available
Capital gains reporting	Yes	Yes
Tax report export (CSV/PDF)	Yes	Yes
Support for U.S.-specific tax rules	Fully supported	Partial

These distinctions highlight Mezzi’s focus on proactive tax planning compared to Sharesight’s emphasis on reporting past activity.

AI Guidance vs. Manual Reporting

Mezzi employs AI to continuously monitor your accounts, providing personalized alerts in real-time. For example, if your portfolio’s equity allocation drifts, Mezzi suggests tax-efficient rebalancing and can answer specific financial questions instantly.

Sharesight, by contrast, requires users to sync brokers or manually upload trades. While it allows detailed reporting and analysis, users must interpret the data themselves. This manual approach may appeal to those who prefer hands-on control but lacks the proactive alerts Mezzi provides.

Security, Regulation, and Fiduciary Alignment

Mezzi operates as an SEC-registered service with fiduciary alignment. It uses secure, read-only access to your accounts, ensuring your login credentials remain private. Mezzi doesn’t execute trades or move money, and its fiduciary status guarantees that its recommendations are designed to prioritize your best interests.

Sharesight also employs strong data security measures but functions solely as a reporting tool. It does not offer fiduciary guidance. For investors who value both technical security and advice aligned with their interests, Mezzi’s fiduciary status may stand out as a key advantage.

Which Platform Fits Your Needs?

Mezzi and Sharesight cater to different types of investors. The right choice depends on your specific needs and financial habits.

High-Income U.S. Professionals with Multiple Accounts

For professionals like doctors, tech employees, or senior executives managing a mix of accounts - such as a 401(k), Roth IRA, taxable brokerage account, HSA, and equity compensation - Mezzi may be a better match. Managing multiple accounts can sometimes result in missed opportunities or inefficiencies. For example, holding bond funds in a taxable account instead of an IRA, overlooking tax-loss harvesting opportunities, or forgetting about an old 401(k) from a previous job can quietly reduce returns over time.

Mezzi’s unified dashboard brings these issues to light. It can identify overlapping investments, like holding the same S&P 500 index fund across multiple accounts, or suggest moving a high-yield bond fund from a taxable account to an IRA for better tax efficiency. Unlike Sharesight, Mezzi incorporates U.S. retirement accounts into a broader financial plan, offering recommendations on asset placement to align with your overall financial goals.

For those who prefer diving into detailed metrics, another option might be more suitable.

Investors Who Prioritize Detailed Performance Data

Sharesight is ideal for investors who want to analyze performance in detail. It offers time-weighted and money-weighted return calculations, separates dividend income from capital gains, and provides detailed attribution data for each holding. If your focus is on understanding the exact performance of your investments - right down to individual tax lots - Sharesight delivers that level of depth.

Mezzi, on the other hand, takes a planning-focused approach. Its performance reports link your portfolio’s results to your financial goals, rather than diving deep into granular data. For investors who already have a clear strategy and want an analytical tool to track performance, Sharesight may fit better.

DIY Investors Who Execute Their Own Trades

Self-directed investors don’t have to compromise between control and guidance. Mezzi’s advice-only model works alongside your existing brokerage accounts at platforms like Fidelity, Schwab, or Vanguard. You retain full control over your trades while Mezzi provides tax-aware suggestions and scenario analyses based on your account data.

Sharesight, by contrast, acts as a performance tracker. It accurately records your trades and returns but doesn’t offer any advisory input. If you’re looking for a tool to document and analyze your trades without guidance, Sharesight fits the bill. If you want recommendations to complement your self-directed approach, Mezzi offers insights without requiring you to relinquish control.

Conclusion: Mezzi vs Sharesight - Key Takeaways

For U.S. investors weighing performance tracking against actionable financial advice, the choice ultimately depends on what you value most. Each platform offers distinct benefits tailored to different needs.

Sharesight shines when it comes to detailed performance analytics. It provides in-depth return and dividend tracking, making it a great option for self-directed investors. However, its tax reporting is primarily designed for Australia and New Zealand, which may leave U.S. investors wanting more comprehensive support for their tax filing needs.

On the other hand, Mezzi takes a broader, decision-focused approach. It consolidates your entire financial picture - including 401(k)s, IRAs, HSAs, taxable brokerage accounts, and more - and uses AI to deliver tailored insights. Whether it’s identifying tax-loss harvesting opportunities, spotting wash sale risks across accounts, or highlighting asset location inefficiencies, Mezzi provides actionable guidance grounded in U.S. tax laws and retirement strategies. As an SEC-registered fiduciary, it prioritizes advice aligned with your best interests without the high costs of traditional advisors.

The key question to ask yourself is: Do you need better data, or better guidance? Sharesight equips you with the tools to analyze your investments independently. Mezzi, however, focuses on helping you act on that data with personalized, fiduciary-aligned recommendations.

	Mezzi	Sharesight
Ideal for	U.S. investors managing multiple accounts who want AI-driven guidance	DIY investors who want detailed performance history and reporting
Tax support	U.S.-focused optimization (harvesting, Roth conversions, asset location)	Optimized for Australia & New Zealand; limited U.S. tax reporting
Advice	AI-driven, fiduciary-aligned recommendations	Data and reporting only
Account coverage	401(k), IRA, HSA, brokerage, cash, real estate	200+ brokers, 250,000+ securities across 35+ exchanges

For U.S.-based investors juggling multiple accounts and looking for a platform that connects the dots - identifying inefficiencies, offering tax-smart strategies, and aligning with personal goals - Mezzi may be the better choice. If your main focus is keeping a detailed, exportable record of your investment performance, Sharesight offers the depth you need. Ultimately, the decision comes down to whether you prioritize detailed analytics or actionable, fiduciary-guided insights.
