Getting Started with Mezzi: Your First 15 Minutes
Last updated: August 20, 2026
Overview
Getting started with Mezzi takes one step: connect a single account. Once that account finishes syncing — usually a few minutes — you'll have a working net worth figure and can run Exposure X-ray on it, which is the first thing worth looking at. You don't need to connect everything today, and you can add anything unsupported by hand.
🧭 How to Connect Your First Account
Open the Profile tab.
Select Accounts (assets & liabilities).
Select Connect a new account.
Search for your institution and choose the entry that matches it.
Complete the login and any multi-factor step in the window that appears. This runs inside the provider's flow — your credentials are never passed to Mezzi.
Choose which accounts at that institution to bring in, and confirm.
Mezzi routes each institution through the connection provider that works best for it — Plaid, Finicity, SnapTrade or Meld. You won't be asked to pick one, and there's no provider selector to hunt for. If a connection fails, the Couldn't connect screen offers an alternative route; see Troubleshooting Account Connection.
What to expect while it syncs
Balances usually appear first, then positions, then transaction history. It's normal for a newly linked account to show a balance with holdings still filling in for a short while.
Two things are worth knowing before you conclude something is broken:
A brand-new account can briefly show as cash while holdings are still being classified. Give it a full sync cycle before reporting it.
Cost basis and realized gain/loss depend on how much history your institution returns. Some brokerages send years; some send very little. That shapes performance figures, not your balance.
What to do first
Once one account is in, open Diversification x-ray. Almost everyone finds something they didn't expect — the same handful of megacaps arriving through three different funds, or a sector weight well above what they thought they held. It's the fastest demonstration that Mezzi is seeing through your funds rather than just listing them.
After that, add the rest as you have time. Mezzi is more useful the more complete it is, but there's no setup gate — nothing is locked until you've connected everything.
💡 Why This Matters
Connect the largest account first. Net worth, allocation and X-ray all get meaningfully more accurate with the single biggest account in place. It's the highest return on five minutes.
Add anything unsupported manually rather than leaving it out. Private investments, real estate, a small employer plan behind a portal that no aggregator reaches — all can be entered by hand, or extracted from a PDF or CSV statement with Document scan. A manual entry that's roughly right beats a gap, because Mezzi's advice only reflects what it can see.
Employer retirement plans are the most common first-try failure. If a 401(k) or 403(b) doesn't connect on the first entry you find, try the alternative entry for the same provider in search results before assuming it's unsupported.
Important Notes
Manual accounts do not sync on their own. If you enter a value by hand, you update it by hand — unless you provided ticker symbols, in which case prices track automatically.
Connecting accounts is unlimited on every tier, including free. What differs by tier is AI access, not how much of your financial picture you can bring in.
🗨 Still Need Help?
If an institution won't connect, email help@mezzi.com with the institution name, the login URL you use, and the account type. That's what support needs to check routing or escalate to the provider. You can also text or call (415) 763-6997.
Common Questions
How long does the first sync take? Usually a few minutes for balances and positions. Transaction and cost-basis history can take longer and depends on how much your institution returns.
Do I have to connect every account before Mezzi is useful? No. One account is enough to get a net worth figure and run Exposure X-ray. Advice gets more complete as you add more, since Mezzi can only reason about what it can see.
What if my institution isn't supported? Add the account manually, or upload a statement with Document scan. See How to Manually Add an Account in Mezzi.
Can I try Mezzi without paying? Yes. The free tier includes unlimited account connections, net worth, allocation, performance and Exposure X-ray, with limited AI access. Unlimited AI advice starts at Core.
