Why did Autumn need a new brand?
Where Autumn was
Hundreds of AI apps already ran on Autumn. Its leaf logo lost detail at small sizes, and the brand lagged the infrastructure.
What Autumn asks its buyers to do
Hand their pricing and billing, which means their revenue, to Autumn instead of building it in-house.
What they asked us for
A brand and website sprint: a new identity, a new website, and the code.
Why it mattered
Engineers don't run revenue through a tool that looks like a side project.
Critical challenge
01 / 02
Autumn's logo had to work at favicon size.
Problem
The old leaf mark lost detail as it shrank, and leaned on colour to work.
Why it mattered
Developers meet Autumn as a small mark: a browser tab, a GitHub avatar, a docs sidebar. That's where an infrastructure brand earns trust.
What we did
We explored line, torii gate, pixel and abstract leaf marks. We kept the leaf the team loved and rebuilt it as a simple abstract form. At small sizes, the background drops and the mark stands alone.
Outcome
The mark was locked in a single review, and ships in the brand guide with sizing rules.
Critical challenge
02 / 02
Autumn's brand had to be bold and still read in one scroll.
Problem
Autumn wanted to be remembered: dark, retro, neon. It also wanted no clutter.
Why it mattered
An engineer evaluating billing scans for pricing models, the API and proof of scale. Bold isn't the risk. Bold that gets between the buyer and the docs is.
What we did
We merged three directions into one: Japanese retro tech, neon on dark, straight lines and dither textures. We chose the spacious layout and removed the scroll hijack. Developers get a copy-to-terminal install command; buyers get the logo wall, a SOC 2 Type 2 highlight and a production-scale section. We built it in Next.js, the way Autumn's engineers work.
Outcome
Autumn merged our code into its own open-source repository and ships on it.
And this is where Autumn ended up.
Autumn left with a brand guide, the logo suite, a dev handoff file, the animations and the Next.js code.
We wrote the first draft of the copy; Autumn's team finalised it. We designed the brand and the site, built it and made the motion.
If your brand is already locked and you only need throughput, a design subscription is cheaper.

Rarely. Most clients come to us with something functional that no longer matches their ambition. We keep what works and rebuild what holds you back.
