Brand Guidelines · v3.0 · May 2026

We don't
pitch.
We send
invoices.

Conversion System is an AI agency for mid-market B2B. We name a number. We hit it. We send the bill. If we miss, we don't. There is no third path.

01 / MANIFESTO
01 · The Manifesto

Most agencies are
partners.
We are vendors.

Partners stay attached. Partners go to your offsite. Partners need to be managed. Six months in, partners are billing $40,000 a month and your conversion rate has not moved.

Vendors finish the job. Vendors hand you the keys and leave. Vendors charge once.

We are vendors.

We use AI because it makes us faster and cheaper. We do not romanticize it. AI is a multimeter. The carpenter still owns the result.

You give us a number. We hit the number. We send a bill. If we don't hit it, we don't send a bill. There is no third path.

If you want a partner, the lobby is that way.

— The team at Conversion System
02 / LOGO
§ 02

The mark.

Construction

Inter Tight Bold. CONVERSION and SYSTEM in all caps. One orange slash between them.

The slash is the cut. It is the work the agency does between a visitor and a customer. It is not decoration.

The descriptor "an AI agency" sits to the right of the wordmark in small caps. It exists because nobody knows what we do from the name alone. It is a fact, not a tagline.

Treatments

Three. Ink on Paper. Paper on Ink. Paper on Indigo. Nothing else.

Misuse
Don't
No gradients. No drop shadows. No AI-generated illustrations behind the mark. The mark is type. Treat it as type.
Don't
Don't tilt the slash, color it gold, or replace it with an arrow. The slash is a cut, not an ornament.
Don't
Don't lock the wordmark up with a tagline like "growth, reimagined." If you need a tagline, use "an AI agency."
Don't
No teal. No purple. No gradient. Stay inside the six colors.
03 / TYPOGRAPHY
§ 03

Two faces.

The system

Geist does the work. Headlines, body, UI. Inter Tight stays as the fallback.

JetBrains Mono is for receipts. Numbers, prices, page references, invoice fields. Mono is the sound of a printer.

Instrument Serif is permitted in one place: pulled quotes from a real client, in italic, surrounded by quote marks. It is not a brand voice. It is a witness.

04 / COLOR
§ 04

Six colors.

Discipline

Paper, Ink, Indigo, Orange. The four that do most of the work. Court, Solar, and Cobalt sit underneath for callouts, data, and supporting links — not for decoration.

Every color has one job. If you can't name the job, don't use the color.

Orange is the verb. Use it once per page, twice maximum. It marks the action, the price, the win. If everything is Orange, nothing is Orange.

Indigo is the brand. It anchors the page — the wordmark, the manifesto card, big surfaces. Don't dilute it with tints.

§ 05

How we talk.

The posture

A contractor who's done the job 200 times and is mildly annoyed you asked. Confident. Terse. Slightly mean to the competition. No flattery. No hedging. No second sentence when one will do.

Numbers, names, dates. Every claim has all three. If it doesn't, we don't make the claim.

Short sentences. One idea per sentence. Period. Never an exclamation point.

Numbers, not adjectives.
Replace every adjective with a measurement. "Significantly faster" is nothing. "Cuts checkout from 4.2s to 1.1s" is everything.
Don't writeSignificantly improved conversion
WriteConversion went from 1.4% to 3.1% in 8 weeks
02
Verbs, not nouns.
Agencies write in nouns. Implementation. Optimization. Operationalization. We write in verbs. Built. Shipped. Doubled. Refunded.
Don't writeConversion rate optimization implementation
WriteWe rebuilt their checkout. Bookings doubled.
03
Receipts over promises.
Don't say what you'll do. Say what you've done. Every claim has a name, a number, a date range. If we can't say all three, we don't make the claim.
Don't writeWe help businesses grow with AI

No partner talk.
We are not your partner. We are your vendor. We finish the job and leave. The word "partner" is banned in client copy.

Say what you mean.
If something didn't work, write that. If a target was missed, write that. Honesty is cheaper than reputation management. The homepage names a missed target with the client's permission. They became a longer client because of it.

06 / SAMPLES
§ 06

In the wild.

Six things we say, the way we say them.
On pricing
Forty-eight thousand dollars. Six weeks. One number to hit. The price does not move.
On AI
AI is a tool. We use it the way an electrician uses a multimeter. Stop romanticizing it.
On retainers
We don't do retainers. Retainers are how agencies stay paid after the work runs out.
On meetings
One kickoff. Two checkpoints. One handoff. If you want weekly meetings, hire a consultant.
On the competition
They sell hours. We sell the conversion rate. You can guess which one is more expensive.
On a missed target
We missed by 4 points. We refunded the engagement. We're still building until you hit it.
Words that get you fired.

IF YOU TYPE ONE OF THESE, DELETE THE SENTENCE AND WRITE THE ACTUAL VERB.

§ 07

Building blocks.

The kit

The kit is short on purpose. Buttons. Receipts. A comparison row. A byline. A manifesto card. Most pages are typography on Paper. Components do the rare structural work.

08 / HOUSE
§ 08

The house.

House structure

Conversion System is the parent. Products and sub-brands sit underneath, each with its own visual language and its own voice. The parent brand never appears on the product surfaces.

Kyra is product-shaped. Dark. Spec-sheet. Model numbers. Conversion System is agency-shaped. Paper. Type. Signed by humans. The contrast is the point.

Conversion SystemParent · agency
An AI agency. Mid-market B2B clients. Fixed-price engagements. The team that builds and operates the products. conversionsystem.com

The AI receptionist for local service businesses. Self-serve, $49–$999/mo, MK-01 product line. Engineered. Dark. Spec-sheet brand. meetkyra.com

AuditLead-gen tool
The free conversion audit. Lives on the parent site, generates the leads that become Studio clients. Technical, generous, instantly useful.
Future productsTBD
When we build the next thing, it gets a product brand of its own. Conversion System remains the parent.
What they share, what they don't
They share
The hiring bar. The pricing philosophy (fixed, named, refundable). The stance on AI as a tool, not the product.
They don't share
Typefaces. Color palettes. Component kits. Voice. Logo systems. Each brand earns its own visual language.
