The name
A tree at the western edge of the world, whose blossoms light the ground below.
In the Shanhaijing, Fusang stands in the east, where the sun rises. Ruomu stands opposite it at the western extreme, where the sun comes to rest. What the old texts single out is not the tree's height. It is the direction its light travels — downward, onto the ground, onto the things standing on it.
Every Ruom product does the same thing. It takes a claim recorded somewhere remote — a registry filing, a renewal survey, a booking app's promise — and lights up the fact underneath it.
The source texts
Ruomu appears across the Warring States and Han corpus. Three passages carry the name's whole meaning — a red tree, a downward light, and a branch raised against the end of the day.
青叶赤华，
名曰若木。
末有十日，
其华照下地。
聊逍遥以相羊。
What we take from it
Three readings. The first is the company; the other two are its shape.
Light on the ground
Ruomu's blossoms do not illuminate the sky. They light what is underneath. Ground truth is not a slogan at Ruom — it is the deliverable, three times over.
Is the defendant actually at that address? Will this resident actually renew? Will the seat actually be at the curb at 4 a.m.? In each case a system of record has already answered, and the answer is a claim until someone goes and looks.
Across the hemispheres
Fusang in the east where the sun rises, Ruomu in the west where it sets — the two ends of one arc.
Ruom Inc is incorporated in the west and works into the eastern hemisphere. Hemisphere runs that axis literally: American firms, Chinese ground, eight cities between the filing and the fact.
One trunk, three branches
A tree is not a portfolio. Ruom's three products serve three unrelated buyers, and they are still one organism.
They share a root system: one stack, one security model, one refusal to publish a number we cannot trace back to something observed. Each branch carries its own light — which is why each product owns a colour and never borrows another's.
From 若木 to Ruom
Two characters, two syllables, one contraction. Nothing was invented — the name was already there.
Two syllables. "ROO-uhm." English speakers reach for "room" on sight, and a name people are unsure how to say is a name they avoid saying. So we print the pronunciation once, in the places where someone first meets us, and never rely on them guessing right.
The mark
An R assembled from cells on a four-by-four grid — a letter built out of discrete, countable units, which is also how every Ruom report is built. The step descending to the lower right is the light going down: 其华照下地.
Construction
At size, and inverted
NO OTHER CHANGE IS PERMITTED.
NO OTHER CHANGE IS PERMITTED.
The primary lockup
Mark and wordmark on the 青叶 field. This is how the company signs its own name — on a cover, a deck, an office wall. Products never appear on this field; it belongs to Ruom.
FIELD #1D5F45 青叶 · GLYPH AND TYPE PURE WHITE · NO OTHER COLOUR ENTERS THE LOCKUP
Palette
The source text gives us two colours before we choose any: 青叶赤华 — green of leaf, red of blossom. 青 is the field the company stands on; 赤 is the light it casts. Then three branch-lights, and a neutral ramp that does most of the actual work. Colour here is a wayfinding system, not decoration — a visitor should know which business they are reading before they read the heading.
Typography
Three faces, three jobs. Nothing decorative — the monospace exists because numbers have to line up, and the serif exists because 若木 deserves to be set properly.
Tight tracking (−0.035em) at display sizes, near-zero at body. Weights 520–640 only; nothing lighter survives on a dark ground.
Every metric, every eyebrow, every status. Tabular figures so a counting number does not shift the layout while it animates.
Songti for classical Chinese. Set it large, tracked open at 0.04em, and never mixed into an English sentence as ornament.
Voice
A company whose thesis is ground truth cannot write in abstractions. The test for any sentence: could someone go and check whether it is true?
| We write this | Not this |
|---|---|
| "An investigator goes to the address and photographs what is there." | "Leveraging our on-the-ground network to deliver actionable intelligence." |
| "Eight cities. More on request." | "Nationwide coverage across China." |
| "The score, its calibration curve, and its feature importance are on one screen." | "AI-powered predictive insights into resident behaviour." |
| "A seat is held for fifteen minutes, then released." | "A seamless, frictionless booking experience." |
| "The software manages workflow, files, and delivery. People do the investigation." | "End-to-end automated verification." |
Naming
Ruom is the root, not an umbrella brand stamped on three things. Products carry their own names and their own customers.
The company
Ruom Inc in legal and formal contexts; Ruom everywhere
else. Never RUOM, never ruom in running prose — the
lowercase belongs to the wordmark only. Chinese contexts may use
若木 alone; it does not need a transliteration beside it.
The products
Hemisphere, Commons, Lillian Wright. On
first mention outside our own properties: "Hemisphere, a Ruom company." Never
"Ruom's Hemisphere" — the possessive makes a product sound like an asset rather
than a business.
Where names differ
Lillian Wright ships to travellers as Lili Ride. Hemisphere lives at
hemispheresupport.com. Keep the split deliberate: the operating
entity is what we say to partners, the consumer brand is what we say to the person
booking a seat.
Saying it
/ˈruː.əm/ — "ROO-uhm". Put it in the footer of decks, the About page,
and the first slide of any pitch. Two syllables, from ruò mù. It is
not "room", and correcting people later costs more than telling them first.
A note on the sources
The east–west split we lean on is the Shanhaijing and Huainanzi reading: Fusang east, Ruomu west. It is the dominant one, not the only one. Qu Yuan uses the two names almost interchangeably in the Lisao, the Hainei jing places Ruomu in the south, and Li He writes "天东有若木" — Ruomu in the east — outright.
We are keeping this paragraph on the page. A company that sells the difference between a record and a fact should not quietly round off an ambiguity in its own origin story.
