Connect Bank Accounts to Mezzi: Cash Context for Investing

Updated September 26, 2026.

Archived article dated February 4, 2025. This dated product update has been edited for clarity. Launch details and roadmap statements below refer to the original publication date; screenshots are historical illustrations. See current membership options and the Mezzi help center for today’s product details.

We're thrilled to announce bank account connections, making it easier than ever to have a clearer picture of your cash balances. This is a top requested feature, so we're really excited to unveil it.

Note, these connections are in beta. We'll be streamlining the connection process and adding support for additional banks. Please let us know if you encounter any issues.

How much cash should I keep?

Keeping funds in cash is personal—you may need it for a downpayment on a house, a new car, or building up an emergency fund.

For illustration, $10,000 compounded at a constant 7% a year would grow to about $19,672 after ten years or $76,123 after thirty years, before fees, taxes and inflation. These are hypothetical investment balances, not guaranteed missed gains: a fair cash comparison also includes the interest cash earns and the different risks.

How can Mezzi help?

1. View your family's total cash: Understand your family's total exposure to cash

2. Compare across accounts: Understand and track opportunities to put cash to work, whether that is in a retirement, taxable, or checking account.

3. Review your allocation: Discuss whether cash is committed to a near-term purpose and what information is needed before considering an investment or sale.

4. Shared views with a partner: Invite your partner to connect their accounts (without having to share passwords) and stay on the same page regarding how much of your wealth should be invested vs. in cash.

Start connecting your banks in Mezzi

1. Navigate to the Profile page

2. Go to Linked brokers

3. Press Connect new account

4. Scroll to Other if your bank isn't on the list

Give cash a purpose before calling it excess

An illustrative $30,000 bank balance might include $15,000 for emergencies, $10,000 for a near-term purchase and $3,000 for upcoming bills. That leaves $2,000 unassigned. Ask Mezzi to show the calculation using your own purposes and dates; the full balance is not automatically available for long-term investing.

Cash can earn interest and protect near-term spending from market declines. A higher assumed investment return does not remove volatility, taxes or the possibility of losing money when you need it. Compare the purpose and time horizon as well as the projected amount.

What should I check after connecting?

Reconcile the balance and account owner with the bank, check the last update, and look for duplicate accounts if the same institution was linked before. Connecting a bank for analysis does not transfer its money to a brokerage.

The menu path above is the one described in the February 2025 beta. Use current help instructions if the account-connection screen has changed.
