Brand & identity system

Joule

The metering and cost-control layer for agentic AI. This page documents the full identity — name rationale, voice, logo, color, and type — so every surface stays coherent.

Tagline: Every token on the meter.
Positioning

Joule meters, attributes, and optimizes every Claude Code token a team spends — turning agentic AI from a scary black box into a managed line item.

Voice & tone

Three adjectives: Precise · Candid · Grounded.

Do — lead with numbers ("$41.78 in 38 min"), name the source, describe what's removed.
Don't — say "seamless", "leverage", "delight", or stack three adjectives where one will do.
Persona

Maya, VP Engineering at a 180-person Series B. Her Anthropic bill went from $4k to $38k in a quarter and finance just asked her to justify it line by line. She can't — yet.

Naming · shortlist

10 candidates explored. One chosen.

Abstract, brandable, ownable names — not literal descriptions. The primary pick is marked; the rest are kept for reference. (Domains reviewed separately.)

JoulePRIMARY

PRIMARY — the SI unit of energy. A joule is a measurable quantum of work; every agent token is a joule of compute spent. Short, ownable, instantly evokes measurement + energy without describing the product literally.

Ampere

A unit of electric current — the *flow* of usage through your fleet. Strong metering association; slightly long, reads more hardware than software.

Tally

Plain-spoken "keep the count." Warm and legible, but more literal and less ownable than a coined/unit name.

Coulomb

Unit of electric charge — distinctive and scientific, but harder to spell and say out loud.

Obol

An ancient unit of currency — evokes the cost ledger and per-task price. Distinctive and short, but obscure.

Watt

Unit of power = rate of spend. Punchy, but heavily used as a brand across energy.

Quanta

Discrete units of usage — modern and techy, leans generic in AI naming.

Meridian

A line of measure across a sphere — premium and calm, but abstract away from the metering idea.

Cadence

The rhythm of spend over time — elegant, but widely used in B2B SaaS.

Voltage

The pressure behind the spend — energetic, but verbose and trademark-crowded.

Logo

A type-led wordmark + a meter-dial monogram.

The mark abstracts a gauge: a swept arc, a needle and a pivot — measurement reduced to geometry. The "l" in the wordmark carries the accent, a small nod to a needle at rest. Built entirely in SVG; never rasterized.

Color system

Phosphor-signal green on instrument-panel ink.

An 11-shade brand scale, an ink-neutral scale, and semantic tokens. Dark mode is the default surface; a warm-paper light theme is available.
