FIFTYSEVEN is an independent climate tech branding agency and web design studio, remote by design, founded in 2016 and led by Petar Stojakovic, working with founders in Switzerland, the UK and the US. It builds brand strategy, identity, pitch decks, websites, 3D and motion for cleantech companies with a working technology, not a mission statement, from pre-seed to Series A. Its published climate work is DePoly SA, in chemical recycling, and Yova, now Inyova, in sustainable investing.

The deck always reaches commercial scale before the plant does.
By the second meeting, the slide has reached a technical advisor, who wants the tonnes per year, the mass and energy balance and the hours the pilot has actually run. An industrial partner asks for a sample, and the offtake talk waits for it.
Both want to know where the company really stands, and both will learn it: on the website, or later, in the data room.
The gap between the deck and the plant surprises no one. Finding it on their own does.

HOW CLIMATE TECH COMPANIES AVOID GREENWASHING IN THEIR BRAND AND WEBSITE
Greenwashing is not the only way to lose the room. It is the obvious failure, and an informed reader spots it in a second. The quieter failure is a true claim stated one size too large:
"Recycles plastic", when the process takes PET.
"Commercial plant", when the plant is commissioned and has not yet reached commercial operation.
"Lower emissions", when the life-cycle assessment is still a draft.
Each is close enough to true to survive the homepage, and wrong enough to fail the diligence call. None of that is a reason to sound small. It is a reason to be exact, and to the people who decide, exact reads as confident.
WHO CHECKS THE CLAIM, AND WHAT THEY NEED TO FIND
WHO READS IT
WHAT THEY CHECK
WHAT THE WEBSITE SHOULD CARRY
A journalist or a policy reader
What happens at scale, and who else claims the same
Plain-language claims with a source attached
A senior scientific or engineering hire
Whether the technology is real and the team serious
The people by name, the plant on camera, and the problem they would own
An investor's technical advisor
The mechanism, the yields, the mass and energy balance, the techno-economic analysis, the stage of the plant
A process explanation a specialist recognises and a generalist can follow
An industrial partner or offtaker
Whether the output meets their specification, and at what volume
A route to verification: a sample request, a data sheet, pilot data
A project financier, or the independent engineer they send
Whether the offtake is binding or a letter of intent, what share of capacity is contracted, the feedstock supply agreement, nameplate capacity against demonstrated throughput
One story across deck, website and data room, with the figures the engineer's report will test stated the same way in all three
A climate tech brief begins with where the plant stands today and who has to believe in the next one. That is the conversation to start, and it goes to Petar.
Chemical recycling, from PET waste to virgin quality
DePoly SA
Based:Sion and Monthey, Switzerland
Field:Chemical recycling
FOCUS
In chemical recycling, DePoly takes PET and polyester waste back to the two raw materials it was made from, PTA and MEG, at virgin quality from "unsorted, dirty PET waste", in the company's words.
THE WORK
Recycling had been on the marketing circuit for decades before DePoly, and the brief ran straight into it: stand out, without standing outside the industry. The curved arrows and the vivid recycling colours went; a quieter identity came to the foreground, designed as if it were already the industry's standard.
The process was explained in 3D, by analogy, its proprietary steps never drawn, and the website's main call to action became a sample request, so licensed laboratories could verify the material themselves.
Strategy, identity, 3D, pitch deck and website took four months. DePoly still runs on that system, and the same 3D frames have carried its deck, film and the opening of its Showcase Plant.
Five first impressions, and what should replace them.
HOW IT GOES NOW
WHAT IT SHOULD DO INSTEAD
The homepage opens on a leaf, a globe or the Earth from orbit.
The first screen should show the product at work, in 3D visualisation or photography, not the cause it serves.
The mission leads; the product waits three scrolls down.
Before the first scroll, an industrial buyer should know the problem, the solution and what sets it apart from the alternatives.
The process lives in a PDF, or stays unexplained because parts of it are proprietary.
The principle should be on the page, in motion, with the protected steps left out.
The team page is a grid of headshots.
A senior engineer should see the work itself: the site, the lab and the problem they would own.
The brand still looks like the pilot while the company raises for its first plant.
The brand and website should already read like the company at the next stage, before the financing talks begin.

Investing directly in climate and human rights
Yova, now Inyova
Based:Zurich, Switzerland
Field:Sustainable investing
FOCUS
Not every climate company runs a plant; some move capital. Yova was a Swiss platform, founded in 2017, where people invested directly in companies working on climate change and human rights.
THE WORK
Eighteen months in, Yova asked for its brand, built from the foundation up, carried through the website and its marketing. The balance was the brief: a financial service serious enough to be trusted with savings, and a product warm enough to make impact investing feel personal.
The studio made the identity, the design system, the website and the photography art direction, and Yova came back for an out-of-home campaign. "The project was not easy for us, since our brand and its promise is at the heart of what we do," as Yova put it on Clutch.
Confidentiality is settled at the start: a non-disclosure agreement where the company needs one, and what may be shown agreed before the first sketch. Each phase locks on approval before the next begins.
Every trademark and every file is the company's, entirely. Founder time is planned like money: a few decisive sessions, not a standing meeting through a raise or a plant commissioning.
Petar Stojakovic, Founder and Design Director, is in every meeting the founder, CEO or CMO is in. The daily work is carried by a senior team he puts together for the brief.
CLIMATE TECH SECTORS: PUBLISHED WORK, AND THE BRIEFS WE ALSO TAKE
DePoly and Yova are the published work; the six categories after them wait for their first brief here.
Storage, grid, industrial heat or fusion change the engineering, not the problem: a technology that works still has to be understood by customers, partners and capital that will never visit the plant. The founder knows the science; the studio knows how it reads.

QUESTIONS CLIMATE FOUNDERS ASK
How does a climate tech company avoid greenwashing in its brand and website?
Two ways.
First, by cutting sustainability language that has nothing under it: a claim goes out with its mechanism, its figures and its source, or it does not go out.
Since 27 September 2026, EU consumer rules under Directive 2024/825 ban certain generic environmental claims without recognised excellent environmental performance behind them, and claims of a neutral, reduced or positive impact that rest on offsets. A company selling to industry is not the target, but its customers' marketing departments are.
Second, by giving the brand an identity of its own: a company positioned for its market does not need the leaf and the globe. DePoly's and Yova's were built that way.
Why hire a climate tech branding agency instead of a generalist design studio?
A generalist has to learn what the market, industrial partners and investors expect to find, and that learning curve is rarely right the first time; the client pays for it every time.
Having built brands for a chemical recycler and an impact investing platform, we already know what those three look for. We start there, instead of billing for the lesson.
What should a climate tech website show before an investor or offtaker sees it?
Three pages do most of the work.
A process page, with the mechanism in plain language a chemist would sign: feedstock in, product out. An evidence page, with the source under every figure and the boundary of the life-cycle assessment. And a page for partners, with the shape of the offtake and supply terms and the economics at the next plant's scale.
Do you design climate tech pitch decks?
Yes, after the brand foundation, never instead of it: the deck carries the same visual narrative as the website and every other touchpoint. In climate tech it travels further than anything else the company makes, mostly without the founder. A deck on its own is quoted as its own scope.
Do you do renewable energy web design?
Yes, as a new brief rather than published work; the record here is recycling and sustainable investing. What changes is the reader: energy storage and geothermal companies sell to utilities and grid operators, whose engineers read a website the way they read a tender.
How do you describe a first-of-a-kind plant without overstating it?
By naming the stage as it is, and letting two numbers do the work.
The first plant is the sentence an offtaker and a project financier read most carefully; everything after it is financed on it.
A pilot has hours on stream; a first-of-a-kind plant has a nameplate capacity it was built for and a demonstrated throughput it has actually run, and the website gives both, dated; "commercial" is the word for the day commercial operation is reached, not for the day the plant is commissioned.
When should a climate tech company rebrand?
When the company has outgrown the story it raised on: the process now does more than the homepage says; a first-of-a-kind plant is about to be read by offtakers and financiers in language written for a pilot; a town is about to be asked to host a commercial facility; or it has become the reference point in its category and the brand still reads like a challenger. The rebrand should be finished before the next deck is.
How long does a climate tech brand and website take?
Three to four months from start to a launched brand and website; with 3D visualisation and an explainer film in scope, a little over four. DePoly took four, including a website built in custom code that won Awwwards Site of the Day and the Developer Award.
When a round cannot wait, the studio takes on a rush if it has room, and quotes it on its own line. The rush shortens the brand phase; it never skips it.
How much does a climate tech brand and website cost?
Between the mid and the high five figures for most climate tech engagements, with $30,000 as the smallest project that can still change how a company is read: positioning, the core brand identity and a landing page. The 3D of the process, the film, the deck, the full brand system and the full website, in custom code or Webflow, extend it, each scoped on its own.
An entry engagement usually runs two to three months. Scope comes before price, and the proposal lists what is excluded. More in the studio FAQ.
