Pitch deck and presentation design, UK-wide
Pitch decks that get you the meeting.
Investor decks, sales decks and board presentations from a two-person design studio. We turn a lot of good information into a clear story people remember, and we work with businesses right across the UK.
Investor pitch decks
For start-ups raising money. We help shape the story as well as the slides, so investors get what you do in the first few pages.
Sales and capability decks
The deck you send after a meeting, or present in one. Clear, confident and easy for your team to reuse.
Board and conference talks
Presentations that work on a big screen and don't rely on reading out bullet points.
Templates your team can use
A master template in PowerPoint, Keynote or Google Slides, so every future deck looks as good as the first.
Why Mammoth
A pitch deck has one job: get you to the next conversation. Most decks don’t fail because the idea is weak. They fail because the idea is buried under too many words, too many charts and slides that all look the same.
We’re Stew and Chris, a two-person design studio. Stew handles the story and structure, Chris the design and any animation, and you deal with both of us directly. No account managers and nothing lost in a handover.
Decks that have done the job
We created the brand and investor deck for MoveMed, a medtech start-up from the University of Cambridge, turning dense research into a story investors could follow. The deck helped MoveMed raise millions in funding.
We’ve also designed a series of white papers for Unibloom, a climate platform founded by people from Unilever, Ben & Jerry’s and Bloomberg, a company overview for executive search firm All Leaders, and the annual impact report for B Corp Society. The same thinking goes into every deck: what does the reader need to know, and in what order?
Fewer words, more impact
The decks that work best usually have less on each slide, not more. One idea per slide, a headline that says the point, and room around it so people know where to look. We’ve written about why white space matters if you’d like the longer version.

Good questions
How much does a pitch deck cost?
Every deck gets a fixed price before we start. It depends on how many slides you need and whether you want help with the story and words or just the design. Tell us your budget and we'll be honest about what it can get you.
How quickly can you turn a deck around?
It depends on the length and how ready the content is, but many decks take one to three weeks. If you've got a hard deadline, like a pitch day or a board meeting, tell us early and we'll plan around it.
Can you help with the words and the story?
Yes. A lot of decks need structure more than decoration. We'll help you work out what goes first, what can go and what investors or clients actually need to see.
Which software do you design in?
Whatever you use. We design in PowerPoint, Keynote or Google Slides, so your team can edit the deck after we've finished. We can also make a PDF version for sending.
Do you work with businesses outside Essex?
Yes. Deck work happens perfectly well over a video call, and we work with start-ups and businesses across the UK and Europe.
Can you work from our existing brand?
Yes. We'll follow your brand guidelines. If you don't have any, we'll tidy things up as we go, or design the brand as well.
