7. Free Plan, Subscriptions, Fees, and Cancellations

7.1 Free Plan

Mezzi offers a Free Plan at no charge. The Free Plan does not require a paid Subscription and does not automatically convert to a paid plan. Free Plan features may be limited and may change over time. Current plan features are described on Mezzi’s pricing page.

7.2 Paid Plans and Fees

Mezzi offers Advisory for $39 per month or $399 per year and Concierge for $99 per month or $999 per year.

Testimonials may not be representative of the experience of all clients and are not a guarantee of future performance or success. Past performance does not guarantee future results.

1 NYU study: paper disclosures and historical portfolio comparison

Valerie Baldinger, From Prompt to Portfolio: Generative AI and Retail Investment. Working paper by Valerie Baldinger, a PhD student at New York University’s Stern School of Business, August 2026.

The study uses de-identified Mezzi data from a selected sample; findings may not generalize. Historical constructed-portfolio results are not realized member performance and do not guarantee future returns. Engagement findings are observational and do not establish causation. The author discloses an unpaid contractor relationship with Mezzi and no financial interest in the company. Her NYU affiliation is not an institutional endorsement. Investing involves risk, including loss of principal.

Historical portfolio comparison Section 6.1, pp. 12–13, Figure 3, and Tables D.6–D.7. Figure 3 compares actual advice-following purchases with the same investor’s other purchases within ten trading days of the answer; its purchase-portfolio analysis uses common 36-month histories. Lower concentration refers to underlying-asset concentration. ETF and mutual-fund labels alone do not guarantee diversification; the paper separately measures diversified funds and broad passive equity funds. These purchase results cover advice-following purchases broadly, not only newly introduced investments held at the final snapshot. The separate Table D.6 comparison, p. 50, concerns recommended portfolios. Each comparison pairs a portfolio of recommended securities with a portfolio of the same investor’s alternative post-advice purchases. Both use fixed initial weights and the same 60-month return history. Only advice events with complete histories for both portfolios are included. The main estimates weight advice events equally. Table D.6 also reports favorable results when extreme values are capped and when investors are weighted equally. The approximately 15% figure is calculated from reported average market-Sharpe retention: 82.6 ÷ 71.9 − 1 = 14.9%. It is not a separately reported estimate, an average of individual percentage improvements, or a claim of higher realized member returns. The interpretation as a diversification penalty depends on the paper’s zero-alpha, one-factor model. Volatility and peak-to-trough decline differences are percentage points, not percentage reductions.
