02 — Why Knurla

What your cashsigns up for

01 · Custody
Held in your name

Every bill sits in a segregated account at a qualified custodian, titled to your company. If Knurla disappeared tomorrow, your bills would not.

02 · Liquidity
Same-day withdrawals

Sell before 2pm Eastern and the cash lands in your operating account that afternoon. No lockups, no notice periods, no gates.

03 · Pricing
Treasury rate, minus 0.15%

One flat fee, taken daily from the yield. No spread on the bills, no minimum balance, no charge to move money.

04 · Visibility
Every bill, every day

See each CUSIP you own, its maturity and its yield, updated every morning. Export the full holdings file for your auditors in one click.

05 · Controls
Two approvals for every move

Set approval rules by amount, lock withdrawals to verified accounts, and keep a signed audit log your controller will actually read.

Built to belooked inside

Every bill, every maturity, every cent of interest, in your dashboard each morning and in a holdings file your auditors can open.

03 — The case for idle cash

Most companies keep months of runway in a checking account that pays almost nothing. It is the only asset on the balance sheet that loses value on purpose. Knurla puts it to work without putting it at risk.

Earns from the first night
Interest starts the evening your cash is swept and compounds into your balance every day.
Backed by the US Treasury
T-bills are short-term debt of the United States government, the benchmark for safe, liquid cash.
Liquid by design
Bills mature every week on a 4- to 13-week ladder, so cash is always coming due.

The front end of the curve, September 2026

Four-week bills still pay more than one-year bills. What a gently inverted front end means for where we place your cash this month.

Knurla passes $4 billion in client reserves

Eighteen months after our first sweep, more than 1,400 companies keep part of their runway with us. Here is what they taught us.

How a 13-week T-bill actually earns interest

Treasury bills pay no coupon. You buy them at a discount and get the full face value at maturity. Here is the arithmetic, step by step.

11 — Questions

What finance teams ask us first.

If your question is not here, our treasury team answers the phone on weekdays from 8am to 7pm Eastern.

Talk to treasury

01

What does Knurla actually do?

We move the cash your business is not using into short-term US Treasury bills held in your company’s name, and move it back the same day you need it. You see every bill and every cent of interest in your dashboard.

02

Is Knurla a bank account?

No. Knurla is not a bank and your reserve is not a deposit. Your cash buys US Treasury bills held at a qualified custodian. Bills are not FDIC insured; they are backed by the full faith and credit of the United States government.

03

How fast can I get my money back?

Withdrawals approved before 2pm Eastern arrive in your verified bank account the same business day. After 2pm they arrive the next morning. There are no lockups or notice periods.

04

Where are my bills held?

At a qualified custodian, in a segregated account titled to your company. Your holdings file lists every CUSIP, face value and maturity date.

05

What happens if Knurla goes out of business?

Your bills stay in your account at the custodian. They are not our assets and cannot be used to pay our debts. You can instruct the custodian directly or move to another adviser.

06

Who can move money out?

Only people you give the approver role, and only to bank accounts you have verified. Anything above your threshold needs a second approver, and every step is written to the audit log.
