Feature Comparison

Mezzi's Features

Mezzi is all about simplifying and optimizing your investments through AI. Acting as an AI-powered wealth management layer, it connects your accounts securely using read-only access, so there's no need to move funds around. The goal? To give you a unified, tax-efficient portfolio.

One of Mezzi's standout features is its comprehensive portfolio analysis. The AI dives deep into your portfolio, identifying tax-loss harvesting opportunities, spotting wash-sale risks across multiple accounts, and uncovering overlapping exposures with its Exposure X-Ray tool. On average, users may save on advisory fees, and since Mezzi is an SEC-registered fiduciary, it’s legally required to act in your best interest.

While Mezzi doesn’t handle trades directly, it keeps you informed. For example, if it identifies a tax-loss harvesting opportunity, it sends you a notification once the 30-day wash-sale window closes, so you can repurchase at the right time.

Webull's Features

Webull, on the other hand, is designed for active traders. It offers commission-free trading on stocks, ETFs, options, and fractional shares with investments starting as low as $5. Packed with over 50 technical indicators, 19 charting tools, and a paper trading simulator, it’s a go-to platform for testing and executing trading strategies using real-time data.

"Webull is what happens when you build a trading app for people who actually trade." - Michael Chen, Senior Investment Analyst, Zogby

Unlike Mezzi, Webull focuses on providing tools for self-directed trading rather than offering advisory services. It’s a platform tailored to those who prefer hands-on control and technical analysis.

This comparison highlights the key differences between Mezzi and Webull. Mezzi is tailored for investors seeking data-driven advisory insights and tax optimization without giving up control of their accounts. Webull, on the other hand, is ideal for traders who value technical analysis, low-cost trades, and hands-on strategy execution. Whether you’re focused on portfolio optimization or active trading, these platforms cater to distinct investment approaches.

Tax Optimization and Portfolio Management

Mezzi's Tax Optimization Tools

Mezzi uses AI to scan your linked accounts for tax-saving opportunities, including automated tax-loss harvesting. This feature identifies unrealized losses exceeding $1,000 across accounts, potentially saving users on taxes, based on IRS guidelines.

The platform also includes wash sale tracking, which monitors cross-account transactions to prevent violations of the 30-day rule. For example, if you sell $5,000 in AAPL losses in a Webull taxable account and repurchase the same stock in a Fidelity IRA within 30 days, Mezzi alerts you to the potential $5,000 disallowance. It even suggests alternative ETFs, like VOO, to maintain your portfolio's exposure while preserving approximately $1,100 in tax savings for someone in the 22% tax bracket.

Mezzi also helps optimize asset location by advising where to hold specific investments for better tax efficiency. For instance, moving $40,000 in bonds (with a 4% yield) from a taxable account to a Roth IRA could save around $1,120 annually for someone in the 28% tax bracket. Over 10 years, this shift could result in a projected 7% compound annual growth rate boost.

In addition to tax-loss harvesting, Mezzi enhances portfolio efficiency by integrating overlap analysis into its tools.

Portfolio X-Ray and Overlap Analysis

Mezzi's Portfolio X-Ray consolidates holdings from over 10,000 brokers, revealing overlaps you might not notice. For instance, you could unknowingly have 25% duplicate exposure to tech stocks by holding AAPL in an IRA and QQQ in a taxable account. This tool is designed to address inefficiencies in portfolio management by identifying redundancies.

The overlap analysis assigns a diversification score (1–100) and highlights redundant positions. It also identifies hidden fees, such as 12b-1 charges and expense ratios above 0.5%. Based on Mezzi's 2025 user data, investors may reduce fees by an average of 0.45% annually - equivalent to $2,250 on a $500,000 portfolio - with 65% of users finding overlaps exceeding 15%. For example, an investor with $300,000 spread across Webull and E*TRADE discovered an 18% overlap in semiconductors. Mezzi's recommendations reduced this to 12%, potentially lowering risk and identifying $4,500 in possible tax-loss opportunities.

Webull's Tax and Portfolio Limitations

Webull, on the other hand, lacks tax optimization tools. It does not provide automated tax-loss harvesting, cross-account wash sale tracking, or asset location advice. Users must manually handle tax forms like the 1099, which increases the risk of missing tax-saving opportunities. Additionally, Webull’s portfolio management tools are limited to basic profit-and-loss views, with no options to consolidate external accounts or analyze overlaps like Mezzi's Portfolio X-Ray.

Certified Financial Planner Mark Kantrowitz highlights that Mezzi’s AI-driven tax optimization can increase after-tax returns by 1.2% annually compared to Webull’s trade-focused approach. For a $250,000 portfolio, this translates to about $3,000 in annual tax savings. While Webull may appeal to active traders, it does not address the $2 trillion tax drag on U.S. investments, as reported in 2024 IRS data.

Pricing Comparison

Mezzi's Pricing Tiers

Mezzi takes a different approach to fees, replacing the standard 1% AUM fee with a flat annual subscription. It offers three pricing tiers: Core at $299/year, Plus at $499/year, and White Glove at $1,499/year.

Here’s what you get with each plan:

• Core Plan: Unlimited AI chat, 24/7 portfolio monitoring, Portfolio X-Ray, tax optimization tools, and returns analysis.
• Plus Plan: Everything in Core, plus advanced AI features, enhanced research tools, early access to new updates, and concierge support via video, phone, and email.
• White Glove Plan: Adds one-on-one AI coaching through video calls and unlimited support calls with Mezzi's team.

"You get institutional-grade planning without the 1% AUM advisor fee."

The platform’s flat-rate pricing can lead to significant savings. For example, avoiding a 1% AUM fee on a $1 million portfolio can result in significant savings over time. Mezzi's tax tools may further enhance returns, which could compound into long-term gains.

By contrast, Webull operates on a commission-free trading model with optional fee-based services.

Webull's Pricing Model

Webull offers commission-free trading on stocks, ETFs, and options, with no account minimum required. However, it generates revenue through other means, such as:

• Margin Interest: 8.74% for balances under $100,000.
• Stock Lending: Lending securities held in user accounts.
• Payment for Order Flow (PFOF): Compensation from market makers for directing trades.

There are additional charges for certain services:

• Options Fees: $0.50 per contract for index options; $0.10 per contract for orders exceeding 500 options (excluding index options).
• Outgoing Stock Transfers: $75 per transfer.
• Regulatory Fees: SEC fee of $0.0000206 per dollar of volume and FINRA TAF of $0.000195 per share (capped at $9.79) on sell orders.

Webull also offers a subscription service called Webull Premium, which includes enhanced IRA matches (up to 3.5%) and discounts on futures or index options. This service has attracted approximately 40,000 subscribers. Additionally, Webull provides automated wealth management through Webull Advisors, in partnership with BlackRock, with pricing that varies.

Price Comparison Table

Here’s a side-by-side look at how Mezzi and Webull compare:

Feature	Mezzi	Webull
Primary Cost	$299–$1,499/year (subscription)	$0 commission (free trading)
Account Minimum	$0	$0
Advisory Status	SEC-registered investment adviser	Broker-dealer
Tax Optimization	Included in all tiers	Not available
Trading Fees	N/A (not a trading platform)	$0 for stocks/ETFs; $0.50 for index options
Portfolio Analysis	Cross-account X-Ray and overlap detection	Technical charting and social sentiment
Best For	Wealth management and tax efficiency	Active trading and technical analysis

Mezzi’s subscription model makes it a strong choice for individuals with complex portfolios who want to focus on long-term wealth growth through tax-loss harvesting and smart asset allocation. On the other hand, Webull’s commission-free structure and advanced trading tools are ideal for active traders who value frequent execution without the commitment of a subscription fee.

Security and Fiduciary Standards

Mezzi's Security and Fiduciary Status

Mezzi is an SEC-registered investment adviser, which means it’s legally required to act in your best interest. It connects to your financial accounts using trusted, read-only aggregators like Plaid and Finicity. This ensures that Mezzi never has access to your login credentials. Plus, since Mezzi can’t execute trades or move your money, you maintain complete control over your assets.

The platform’s subscription-based model is designed to align with your goals. Mezzi doesn’t rely on ads and avoids sharing your data with third parties. For added privacy, it also supports Apple login, allowing you to anonymize your email. These features are part of a broader effort to build trust and provide a secure environment for managing your wealth.

This user-centered approach to security sets Mezzi apart from other platforms with different operational priorities.

Webull's Security Features

Webull, on the other hand, operates under a different regulatory framework. As a broker-dealer registered with the SEC and FINRA, Webull adheres to the "best interest" standard outlined in Regulation Best Interest. While this standard is designed to protect investors, it is generally considered less rigorous than the fiduciary duty required of investment advisers.

Unlike Mezzi, Webull directly holds customer assets and provides SIPC protection, covering up to $500,000 per account (with a $250,000 cash limit). In the first quarter of 2025, Webull reported $12.6 billion in total customer assets across its 24.1 million global users. However, its revenue model highlights a potential conflict of interest. Over 54% of Webull’s total revenue - $64.1 million - came from equity and option order flow rebates during that same period. This payment-for-order-flow system contrasts with Mezzi’s flat subscription model, which avoids such conflicts.

These differences underscore the varying approaches to security and transparency between the two platforms.

Which Platform Fits Your Needs

When to Choose Mezzi

Deciding between platforms often boils down to your investment approach. If you're juggling multiple accounts like a 401(k), Roth IRA, and taxable brokerage accounts across different providers, Mezzi might be your go-to. Its Portfolio X-Ray feature offers a clear view of overlapping holdings and uncovers tax-saving opportunities - all without requiring you to transfer assets.

Mezzi is ideal if tax optimization is a key priority. It keeps tabs on wash sale risks across accounts, identifies candidates for tax-loss harvesting or capital gains deferral year-round, and provides advice on asset location strategies (helping you decide which investments are better suited for your Roth versus taxable accounts). While it won't handle trades for you, it delivers fiduciary-level insights without charging the typical 1% AUM fee.

This platform works best for self-directed investors who want expert advice on demand without handing over control of their portfolio. If your portfolio is diverse and tax efficiency is a focus, Mezzi could be a strong fit. Pricing ranges from $299 to $1,499 annually, depending on the tier, so you're paying for guidance and insights rather than transactions.

However, if real-time trade execution is your top priority, Mezzi might not be the best choice.

When to Choose Webull

If your focus is on active trading, Webull is designed with you in mind. The platform caters to traders who need real-time execution and advanced technical analysis tools. For those trading options frequently, Webull's $0 per-contract fees can translate to substantial savings. Plus, its mobile app includes 56 technical indicators and features like "Turbo Trader" for advanced order execution.

Webull is a solid choice if you're interested in trading crypto, forex, or futures alongside stocks and ETFs. It supports over 50 cryptocurrencies with 24/7 trading access, as well as fractional shares and event-based contracts.

That said, Webull has some gaps for long-term investors. It doesn't offer mutual funds, joint brokerage accounts, or specialized accounts like Trusts or 529 plans. If you're aiming for comprehensive financial planning or need to consolidate accounts without moving them, Webull's setup won't meet your needs - it’s a trading-first platform, not a full-service wealth management tool.

Conclusion

The platform you choose should align with your investment approach. This comparison shows how AI-driven insights and hands-on trading tools cater to different investor preferences.

Mezzi focuses on long-term, tax-efficient wealth management. It offers tax-optimization and portfolio insights without the typical 1% AUM fee. Meanwhile, Webull caters to active investors, excelling in real-time trading and technical analysis. With $0 commissions on stocks, ETFs, and options, as well as access to crypto and futures, it’s an attractive option for frequent traders seeking low-cost execution.

Your decision ultimately depends on your priorities. If you need AI-powered tax optimization for a diversified portfolio, Mezzi is a great fit. If you’re focused on real-time execution and advanced trading tools, Webull is the better choice.

Both platforms serve distinct needs - Mezzi for long-term, tax-efficient strategies and Webull for active, cost-conscious trading. Identifying your goals will help you make the right choice.

FAQs

Can I use Mezzi if my accounts are spread across multiple brokerages?

Mezzi allows you to manage accounts from multiple brokerages seamlessly. With its portfolio consolidation and proactive financial insights, you can efficiently oversee and optimize your investments across all your accounts.

How does Mezzi avoid and detect wash sales across different accounts?

Mezzi keeps a close eye on transactions to help identify and prevent wash sales. This means ensuring that substantially identical securities aren’t bought within 30 days before or after a sale made at a loss, in line with IRS regulations. It monitors these activities across all accounts - including IRAs and external accounts - to help maintain compliance and make tax strategies more efficient.

Is Mezzi worth $299/year if I mostly buy and hold ETFs?

If you're primarily focused on buying and holding ETFs, Mezzi's $299 annual fee might come down to how much you prioritize features like AI-driven tax optimization and portfolio analysis. These tools are designed to help long-term investors aiming for tax efficiency. However, if your approach is more passive and doesn't involve active management or tax strategies, the fee might not be worth it for your specific investment style.
