Money Vault vs Brex: Personal Expense Tracker or Startup Card Platform?
Brex gives startups corporate cards with built-in spending limits, automated receipt matching, and real-time budget controls. Money Vault gives you a way to say "coffee 4.50" and have it tracked instantly. One is a financial platform for growing companies. The other is a personal expense app for your pocket. They both involve tracking money, and that's about where the similarity ends.

In this comparison
Quick Overview
Brex launched in 2017 as a corporate card for startups. The pitch was simple: get a business credit card without a personal guarantee, even if your company is brand new. Since then it's grown into a full spend management platform. Cards, budgets per department, automated receipt collection, approval workflows, bill pay, reimbursements, and accounting software integrations. It competes with Ramp, Divvy (now BILL Spend & Expense), and traditional corporate card programs.
Brex is for companies. Not individuals. You can't sign up with a personal email. You need a registered business.
Money Vault is for individuals. You download it, open it, and start tracking expenses. Say "parking 8 dollars" and it's categorized automatically. Scan a receipt from the pharmacy and every line item gets captured. Ask "what did I spend on transport this week?" and the AI gives you a number. No business registration. No credit check. No card application.
What Brex Actually Does
It helps to understand Brex properly, because it's not really an "expense tracker." It's closer to a financial operating system for businesses.
Corporate cards: Brex issues physical and virtual Visa cards to employees. Each card can have custom spending limits by category (travel, software, meals). Cards can be temporary (one-time virtual cards for a specific vendor) or permanent.
Budget management: Finance teams create budgets per department, project, or team. Spending automatically gets tracked against those budgets in real time. If the marketing team has $10,000/month for software, every SaaS charge on their Brex cards counts against that limit.
Automated receipt matching: When an employee makes a purchase, Brex texts or emails them asking for a receipt. It uses OCR to match the receipt to the transaction. This works well for teams that hate chasing people for receipts.
Approvals: Managers can require pre-approval for purchases above a certain amount. Need a $5,000 conference ticket? Submit the request in Brex, your manager approves it, then the card limit adjusts automatically.
Accounting sync: Transactions flow into QuickBooks, Xero, NetSuite, or Sage with GL codes and categories already mapped. The finance team doesn't have to manually categorize hundreds of transactions each month.
All of this is genuinely useful for a 30-person startup or a 500-person company. None of it is relevant if you're an individual tracking grocery runs and coffee purchases.
Personal Expense Tracking
This is where the comparison gets short. Brex doesn't do personal expense tracking. At all. You can't use it to track your personal grocery spending, your Netflix subscription, or how much you spent at restaurants last month (unless those were business meals on a Brex card).
Brex tracks company spending. It answers questions like "how much did the engineering team spend on AWS this quarter?" not "how much did I personally spend on takeout?"
Money Vault is built entirely around that second question. The whole app is designed to help one person understand their personal spending patterns. Voice input makes logging fast. Receipt scanning handles the stuff you'd forget to enter manually. The AI chat lets you ask questions without building reports or exporting spreadsheets.
Can Brex employees use Money Vault for personal tracking? Absolutely. They're completely separate tools. Use Brex for business expenses on your corporate card, and Money Vault for everything you buy with your own money.
If you're a startup founder, you might actually need both. Brex for company spending visibility and card management. Money Vault for keeping tabs on personal finances while you're pouring everything into the business. Plenty of founders forget to track personal spending when they're focused on burn rate and runway. That's how you end up surprised by your credit card statement.

Pricing
Brex has an Essentials plan that's technically free for the card and basic expense management. But most companies quickly move to the Premium tier at $12/user/month, which adds custom approval policies, advanced budgets, and premium integrations. For a 25-person startup on Premium, that's $300/month or $3,600/year. There's also an Enterprise tier with custom pricing for larger companies.
Brex also makes money from interchange fees on card transactions, so the "free" tier isn't charity. They earn a percentage every time an employee swipes.
Money Vault is free for core features: voice input, receipt scanning, categories, and basic stats. Premium unlocks AI chat, advanced analytics, and more. No interchange fees. No business verification. No per-user pricing because there's only one user: you.
These pricing models aren't comparable because the products aren't comparable. Brex charges businesses for financial infrastructure. Money Vault is a free consumer app with an optional upgrade. They're in different categories entirely.
Final Verdict
- Choose Brex if you run a startup or business and need corporate cards, team spending controls, and automated accounting. It's well-designed for that job, especially for VC-backed companies that need clean financial records.
- Choose Money Vault if you're an individual tracking personal expenses. Voice input, receipt scanning, AI chat, 50+ currencies. It's free, it's private, and it works in 10 seconds flat.
These products don't compete. Brex is a B2B financial platform. Money Vault is a B2C personal finance app. If you're here because you heard "Brex" and "expense tracking" in the same sentence and wondered if it works for personal use, the answer is no. Brex is for your company. Money Vault is for you.
