I do like the idea of automated banking to keep me from having to deal with it very much, but it doesn't seem like it's anything I'm not already doing with my bank account. I have my direct deposit pay go to my savings account, and my bank (sofi) has overdraft protection, where if I have no money in my checking it'll pull from my savings. So I'm basically using my savings account as a checking account and getting 3.1% interest on the money in there. Sure, it's not as high as 3.7%, but .6% isn't enough to warrant another money management app, and I don't make enough for it to really make a difference.

So I guess my question is: what does this service do that's different from what I'm doing already with my bank?

Most product posts tell you what something does. Here is the other half, the things Rivo does not do, because knowing the boundaries is how you decide if it is for you.

• Rivo does not hold your money. It is a software layer. Your cash stays in your existing bank and, when it is put to work, in short-term U.S. Treasury Bills held in your name at a regulated brokerage.
• Rivo is not a savings account and does not promise a yield. What you earn tracks short-term Treasury rates, which move. It is not a fixed APY.
• Rivo does not lock up your money. You can pause, move funds yourself, or disconnect at any time.
• Rivo does not move money you are about to need. It watches your balance and upcoming bills and leaves a buffer, so cash is there when a payment hits.
• Rivo does not replace your bank. You keep your existing checking account. Nothing about how you bank changes.

If any of these are dealbreakers, better to know now. If they sound reasonable, that is the shape of the product.

If you already buy Treasury Bills directly, on TreasuryDirect or through a brokerage, you might wonder what Rivo actually adds. Honest answer: if you enjoy managing it yourself, maybe not much. Here is what Rivo does differently.

Buying T-bills yourself means deciding how much to buy, choosing maturities, and rolling them over as they mature, all while making sure you do not lock up cash you will need for a bill. It works, but it is a manual, ongoing job.

Rivo automates that specific loop:
- It watches your checking balance and upcoming bills, so it only moves cash you genuinely are not about to need.
- It handles the timing, moving idle cash into short-term Treasuries and bringing it back before a bill or transfer hits.
- You do not pick maturities or manage a ladder, and you do not move money manually.

What you give up is control over the specifics, and there is a fee for the service (details in the pinned comment). What you get back is not having to think about it.

So: if managing a T-bill ladder yourself is no trouble for you, keep doing it. If the idle cash keeps sitting there because the manual version is one more task you never get to, that gap is exactly what Rivo closes.

A fair question we get a lot: is Rivo just a high-yield savings account? Short answer, no. Here is the difference, plainly.

A HYSA is a bank product. You move money into it, it earns a rate the bank sets, and it is FDIC-insured.

Rivo is not a bank and does not hold your money. It connects to your existing checking account, watches your balance and upcoming bills, and moves the cash you are not using into short-term U.S. Treasury Bills, then brings it back before you need it. You keep your bank. Your money stays in your name at a regulated brokerage while it is in Treasuries.

The practical differences:
- You do not switch anything. A HYSA is a new account to move money into. Rivo works around the account you already have.
- It is automatic. Rivo handles the timing, moving idle cash out and back so you are not managing it.
- Different protection. HYSA balances are FDIC-insured. T-bills held through Rivo are securities protected up to $500,000 at the brokerage level, which is a different thing from FDIC insurance, not better or worse, just different.

If you want a simple place to park savings, a HYSA is great. If the problem is the cash sitting idle in your checking account that you keep meaning to do something with, that is what Rivo is built for.

There is no single right number, but here is a simple way to size it.

A rough framework

• One to two months of expenses in checking. Enough to cover rent, bills, and normal spending without cutting it close.
• Your emergency fund somewhere liquid but higher-yielding. A few months of expenses you rarely touch has no reason to sit at a near-zero rate.
• Everything beyond that is idle cash. It is not earmarked for the next few weeks, and it is the balance most people leave in checking by default.

Big-bank checking often pays close to 0 on your cash, so a large idle balance quietly earns almost nothing. The 4-week T-bill, by comparison, was 3.82% as of July 29, 2026 (source: U.S. Treasury) (rates move).

Rivo is built for exactly that idle portion: it moves it into short-term U.S. Treasury Bills and brings it back before you need it, so it is not sitting still. The framework holds whether or not you use us.

A quick, plain answer to a question worth asking about any fintech: where does your money actually live?

Rivo is a software layer. It moves and times your cash, but it does not hold it. Your money sits with our regulated banking and brokerage partners, in your name.

The two places your money can be

• In your bank: the cash you need for near-term bills and spending stays in your existing checking account.
• In Treasury Bills: the idle portion is held as short-term U.S. Treasury Bills, direct obligations of the U.S. government, in your name at the brokerage. Securities in your account are protected up to $500,000 at the brokerage level.

You stay in control the whole time: pause, move funds yourself, or disconnect whenever you want.

Earning yield on idle cash is only useful if the money is there when you need it. The timing is the part that matters, so here is how Rivo handles it.

How the timing works

1. Reads your patterns: Rivo looks at your recurring bills, transfers, and spending rhythm on the connected account.
2. Keeps a buffer: It leaves enough in your bank for near-term needs, and only moves the cash sitting idle beyond that.
3. Moves ahead of time: Before a scheduled bill or transfer, Rivo returns what you need to your bank, with room to spare.
4. Adjusts as things change: If your balance or your bills shift, the buffer and timing adjust with them.

You are never locked out. You can pause, move funds yourself, or disconnect at any time.

I am Ambrish, founder of Rivo. We came out of beta today, and I'd rather share the story behind it than just an announcement.

Rivo started with a personal annoyance. My former wealth manager left a chunk of my money earning 0% because he needed explicit instructions before moving it, while still charging a management fee. That experience made me realize there had to be a better way to manage idle cash.

The more I looked into it, the more I realized this wasn't just my problem. U.S. households hold nearly $6 trillion in transaction accounts, much of it earning close to nothing. Not because people don't care, but because they are busy, and the system was designed to profit from that.

So we built Rivo. It connects to your existing bank account, automatically puts your idle cash to work, and brings it back before your bills are due. You keep your bank, and you never move money manually.

Before this, I led AI at Cruise during the launch of its robotaxi service in SF, and worked on applied AI at Amazon prior to that. I am also fortunate to be building this alongside an amazing founding team with experience from Personal Capital, Mint, Capital One, JPMorgan Chase, Microsoft, and LinkedIn.

Today, we are also announcing our $2.7M seed round, bringing our total funding to $3.1M, with backing from South Park Commons, Wisdom Ventures, Script Capital, 645 Ventures, 20VC, and Jag Duggal (former CPO at Nubank).

Happy to answer anything about the product, the tech, or what we have learned along the way.

Here is what happens with your money, start to finish.

How it works

1. Connect: You link an existing bank account securely. You keep your bank.
2. Detect: Rivo watches your balance and upcoming bills, and spots the cash sitting idle beyond your near-term needs.
3. Move: Rivo moves that cash into short-term U.S. Treasury Bills, backed by the U.S. government.
4. Return: Before a bill or transfer hits, Rivo moves what you need back into your bank, so it is there when you need it.

Why Treasury Bills

- Short-duration U.S. government securities.
- Interest is exempt from state and local income tax, which matters more in a high-tax area.
- Your money stays liquid the whole time.

You stay in control: pause, move funds yourself, or disconnect anytime.

Questions on any step are welcome below.

If you have wondered why a large bank pays 0.01% on checking, the reason is a concept called net interest margin, and it is worth understanding on its own.

The short version: a bank takes your deposit and lends it out or holds safe assets that earn a market rate. The 4-week T-bill was around 3.82% as of July 2026 (rates move). The bank earns roughly that on your money, pays you a small fraction, often 0.01 to 0.07% at the big banks, and keeps the difference. That difference is net interest margin, the core of consumer banking economics.

This is simply how the model works, but it means leaving cash in checking has a real cost that most people never see, because it appears as income not earned rather than a fee paid.

The options, in rough order of effort: a high-yield savings account (FDIC, straightforward), a money market fund, or short Treasuries held directly (state-tax-exempt, more hands-on).

This is the official community for Rivo.

Rivo helps you earn on your idle cash automatically, with no bank switch. It connects securely to your existing checking account, moves the cash you are not using into short-term U.S. Treasury Bills, and brings it back before your bills hit. Your money stays liquid, and you stay in charge: pause, move money yourself, or disconnect anytime.
