Launch HN: Palus Finance (YC W26): Better yields on idle cash for startups, SMBs
We were funded by YC for a consumer-focused product for higher-yield savings. But when we joined YC and got our funding, we realized we needed the product for our own startup’s cash reserves, and other startups in the batch started telling us they wanted this too.
We realized that traditional startup treasury products do much the same thing: open a brokerage account, sweep your cash into a money market fund (MMF), and charge a management fee. No strategy involved. (There is actually one widely-advertised treasury product that differentiates on yield, but instead of an MMF it uses a mutual fund where your principal is at considerable risk – it had a 9% loss in 2022 that took years to recover.)
I come from a finance background, so this norm felt weird to me. The typical startup cashflow pattern is a large infusion from a raise covering 18–24 months of burn, drawn down gradually. That's a lot of capital sitting idle for a long time, where even a modest yield improvement compounds into real money.
MMFs are the lowest rung of what's available in fixed income. Yes, they’re very safe and liquid, but when you leave your whole treasury in one, you’re giving up yield to get same-day liquidity on cash you won’t touch for six months or more. Big companies have treasury teams that actively manage their holdings and invest in a range of safe assets to maximize yield. But those sophisticated bond portfolios were just never made accessible to startups. That’s what we’re building.
Our bond portfolio holds short-duration floating-rate agency mortgage-backed securities (MBS), which are an ideal, safe, high-yielding asset for long-term startup cash reserves under most circumstances.[1]
The bond portfolio is managed by Regan Capital, which runs MBSF, the largest floating-rate agency MBS ETF in the country. Right now we're using MBSF to generate yields for customers (you can see its historical returns, including dividends, here: https://totalrealreturns.com/n/USDOLLAR,MBSF). We're working with Regan to set up a dedicated account with the same strategy, which will let us reduce fees and give each startup direct ownership of the underlying securities. All assets are held with an SEC-licensed custodian.
Based on historical returns, we target 4.5–5% returns vs. roughly 3.5% from most money market funds.[2] Liquidity is typically available in 1-2 business days. We will charge a flat 0.25% annual fee on AUM, compared to the 0.15–0.60%, depending on balance, charged by other treasury providers.
We think that startup banking products themselves (Brex, Mercury, etc.) are genuinely good at what they do: payments, payroll, card management. The problem is the treasury product bundled with them, not the bank. So rather than building another neobank, we built Palus to connect to your existing bank account via Plaid. Our goal was to create the simplest possible UX for this product: two buttons and a giant number that goes up.

We are live with early customers from within YC, and accepting new customers on a rolling basis; you can sign up at https://palus.finance/.
We'd love feedback from founders who've thought about idle cash management or people with a background in fixed-income and structured products. Happy to go deep in the comments.

All this to say: I'd be in your target market but I'm simply not interested in a "marginally better" treasury system versus just going with my bank's options that make it easy for me.
You've got really significant, broader lesson here for startups at this stage.
I've had an easy time setting up treasury accounts with Rho & Mercury for 2 co's, but the latter gave me a no-go on an account for a non profit.
Our goal is to make sophisticated treasury management easy for startups. With Palus, they don't need to manage a brokerage account, or handle treasury ladders, or anything like that.
There are banks out there that will do business savings accounts not much below this (2.85%) while keeping things safe (FDIC insured) and liquid.

All that is to say: businesses shouldn't treat all their cash the same way, especially when they have significant runway. The exact breakdown depends on the business, but typically you can think of it as three different buckets:
1) You have short-term cash, which you need immediately. This is where you'd use a checking account. This pays very close to 0% but you have immediate access. Most businesses might keep a few weeks' cash here.
2) You have short-term reserves, which is what you'd use in the next couple of months. This is where most companies might use a savings account (or even put it in a money market fund), where you know you can get the cash into your checking account in ~1 day. This pays between 2.5% and up to maybe 3.75%. Each business will structure their cash differently, and some might not even bother having this bucket.
3) Long term reserves, which you won't touch for months. This is where companies try to optimize yield, and where Palus is valuable. Even here, your money is safe, and in Palus's case can usually be in your checking account within a couple of days, but getting extra yield on long-term reserves can be super valuable.
MBS bonds pay a risk premium for a reason, you’re virtually free of credit risk, but you’re assuming interest rate/duration risk (not particularly relevant if duration is low, I’m not familiar with the duration of short term floating rate MBSes)
Also, what happens in a Silicon Valley bank type scenario, let’s say you have lots of withdrawals and you have to liquidate at under face value. Who eats the loss?
I like smart finance plays and I hope you can do that and stand out from the glut of finance bros who have (and continue to) muddied the water (poisoned the well?) with this approach of "tech on top if actual finance companies".
Good luck out there!
Again, I hope this doesn't come as negative, but I'm not sure this is making the risk clear. I am not sure I would suggest my portfolio companies to risk their treasuries unless I am sure they're fully understanding the risks associated. Do you intend to provide anything else?
I think the yield is about 3.2% based on how we set it up to be as liquid as possible. We could have accepted less liquidity for more like 3.8%
There is no free lunch in investing, so that extra yield comes with extra risk. Be that duration, credit, etc. That's not to say MBS's don't have their place, but I would never claim people's mortgages as equivalent to cash in any shape or form. Your website claims MBSF is safe for 3+ month durations, but that is not the avg duration of MBSF held securities, so you are encouraging duration risk.
I haven't read the full prospectus on MBSF, so I'm not an expert on that product, but it seems expensive and complicated, which is not what you want for cash and cash-like things. This should be a hard pass for literally everyone.
Meanwhile you can hold something like ICSH[0] or SGOV[1] with expense in the .09% or lower range(i.e. for every $10k we are talking $9/yr or less in fees). SGOV is 0-3 month max duration, so it's perfect for holdings in the 3 month time-frame. If you need longer time frames you can buy govt bond ladders in whatever time frame you want.
What your product should have been: You specify duration for each of your buckets, and then you pick appropriate, cheap index-based investments that are cheap and easy to reason about for each of the buckets.

5% return is not competitive.
Why not buy Celsius (1) instead, even better yields ;)

Do you work with non-US companies? I have a company in Estonia, and hold some reserve cash (mix of dollars and euro) on a Wise account. It pays 2.20% variable APR, but I’m starting to explore other options :-)
I suppose the Agency MBS holders still had losses during the GFC. Would your clients wear any losses in MBS price of there's another housing downtuurn or recession? Why not diversify into other bonds as well?
1% spread is in fact, pretty small, so yeah, it probably isn't very risky.
If you ever want to pivot an idea I am suprised no one does is why don't long term bets e.g. 2028 president pay interest. When you bet on something almost certain in 5 years you always lose due to lost interest. Maybe bets can include interest or even be chucked in SP500 for duration.
The thing with startups, like with SMBs is that most times are fragile, not-financially sound institutions. At least for startups, those that don't die, usually grow and need the larger scale features anyways.
