Voice

How 53° sounds, in the product and everywhere else. We're inspirational, helpful and optimistic. The personality stays the same. The tone changes with the channel.

Purpose

Why we write the way we do.

We give founders the space to think and the tools to move their business forward, so they can achieve their big ambitions.

Everything we write works towards that. A founder should finish reading with a clearer idea of where they're going, and more confidence that they'll get there.

Personality

The voice has three qualities, and three rules keep them grounded. Each trait sits close to a failure, and the table shows where the line is.

Our voice

How a founder should feel after reading anything from us.

Inspirational
Show founders what's possible for their business, then the step that gets them closer. Lead with where they're going, not what they're stuck on.
Helpful
Every sentence should tell the reader something they can use: what's happening, or what to do next. Inspiration without a next step is noise.
Optimistic
Assume progress. A problem is the next thing to solve, not a failure. Celebrate what's moving, but never promise more than we deliver.

Keeping it grounded

Inspiration only earns trust when it's clear and specific. These three rules keep it that way.

Plain
Big ideas, simple words. Say what happened and what to do next, in the words the founder uses. Write "Couldn't save the stage.", not "An error occurred."
Brief
Space to think means fewer words, not more. A label is a word or two, a description one sentence, a post one idea.
On their side
Call the reader "you", and talk to them as a peer who believes in what they're building. Never blame them. Write "That link has expired", not "You used an invalid link".

We are, we aren't

Every good trait has a failure next to it. Aim for the left column without sliding into the right.

We areWe aren't
InspirationalHype, grandiose or vague
HelpfulPreachy, or doing their thinking for them
OptimisticNaive, or glossing over real problems
KnowledgeableJargon-heavy or superior
DirectBlunt or curt
WarmGushing or matey

Tone by channel

The same voice, turned up or down for where the reader is and what they need.

ChannelToneSounds like
ProductQuiet and precise mid-task. Encouraging when something starts or finishes.No projects yet. Start one and your tasks, files and notes have somewhere to live.
Website and marketingInspirational and concrete. Lead with the ambition, then show how we help.Space to think about what's next, and the tools to get there.
Social mediaOptimistic and conversational. One idea per post. Share progress, never a sales pitch.Less chasing, more building. Proposals are now faster to send.
SupportHelpful above all. Acknowledge, fix, explain, then get them moving again.Sorry about that. It's fixed now. The sync had stalled on one calendar.
Proposals and salesClear and confident about where the work will take them. Facts over adjectives.Here's the scope, the timeline and the price. Reply with any questions.

Words

The terms we use, and the rules a spellchecker can hold us to.

Vocabulary

Use the product's own names for things, everywhere, so marketing and the app never describe the same thing two ways.

Mechanics

Do
  • British English: organisation, colour, cancelled. cspell enforces it in the codebase.
  • Sentence case for titles, headlines, buttons and menu items.
  • Name the thing in errors: "Couldn't update the colour."
  • Use the ellipsis character (…) for "in progress" and for menu items that open more.
  • Write numbers as digits, with the currency symbol: £1,200.
Don't
  • Title Case Buttons or ALL-CAPS words (eyebrows are the only uppercase).
  • Exclamation marks, "Oops" or jokes in errors. Optimism is steady, not shouty.
  • "Please", "simply" or "just". They pad the sentence, or imply the task was easy.
  • Technical detail (codes, stack traces) in anything a customer reads.
  • Ending labels, buttons or titles with a full stop.

Before you publish

Four checks for anything with our name on it: a screen, a post, a proposal or an email.

Does it move them forward?
The reader should finish knowing what they can do next, and feeling able to do it.
Read it aloud
If you wouldn't say it to a customer across a table, rewrite it.
Cut a third
Most first drafts lose nothing when a third of the words go.
Check the facts
Figures, dates and feature names match what ships. No promises the product doesn't keep.
