About · Why We Built It
Kuroji Exists Because Our Own Books Needed It First.
KumoKodo runs eight products across half a dozen Stripe accounts, a credit-union bank that no fintech dashboard supports, and a payroll provider that exports CSVs. The finance question we needed answered every Monday wasn’t one any existing tool would answer. So we built the tool.
We tried the tools. Pry was the closest — and then Brex acquired it, and Mercury, SVB, Chase, Ramp, and credit-union users lost the only thing that worked. We tried Finmark and Causal, and spent more time maintaining the hiring plan than getting an answer from it. We tried Brex IQ and Mercury IQ, useful only if you’ve consolidated onto their one bank.
We have eight live products. Half a dozen Stripe accounts. RBFCU because the credit union has been with the founder since college and the rate is better. Gusto. Three planned hires that haven’t been entered into a spreadsheet because nobody wants to maintain another spreadsheet.
The runway question we needed answered was how long until we die, across all of that. So we built the tool that answers it. Then we built the audit chain underneath, because we’d already built one for Kodori — KumoKodo’s other product, AI document management for law firms — and law firms had taught us what defensibility actually looks like.
Kuroji’s first customer is KumoKodo itself. We pay the actual monthly subscription out of operating cash, against our own books, audited by Kuroji watching itself. If you can find a cleaner dog-fooding loop in fintech we’d like to hear about it.
The Character
A Devoted Second-In-Command. Perpetually One Step Ahead.
Kuroji’s tone is restrained on purpose. Founders are already exhausted; they don’t need a finance tool with the confidence of a sports anchor. They need the financial second-in-command who reads the room before the room is in it. Vigilant. Hyper-prepared. Anxious-on-the-founder’s-behalf without ever being anxious-at-the-founder. The kind of teammate who quietly drafts the investor update before you remember it’s due.
If we’ve done our job, Kuroji feels like the most conscientious chief-of-staff you’ve ever had — except this one watches your bank, knows your books, and never sleeps.
The Name
黒字 · Kuroji
黒字 (kuroji) — Japanese for in the black, the state of being profitable. Literally: black-letters. The opposite of 赤字 (akaji, red-letters), the state of being in the red.
Kuroji’s job is keeping you in the black. The kanji is the brand mark in every direction.
