Endpaper is the design studio of PureTensor, Inc., led from London, with an infrastructure company behind it. Identity, print, websites and apps, pictures and motion, made by the same team that builds and runs them. Most studios hand your site over at launch and leave the hosting to someone else. We stay on and run it for you ourselves, on AWS.

Real work.
Live now.

Everything here is real and running. Click through, scroll, load it on your phone. Sites we host for Tina Mullins and Helen Helga, the site and editorial programme we run for Bretalon (where our founder is a minority shareholder), and the papers we set for PureTensor, the company Endpaper belongs to.

A gallery that lets the work breathe

Artist, acrylic on canvas

Made here.

Brand work, paper covers, an interior render and a twelve-second walkthrough film, designed in-house, with AI design and image tools as part of how we work. The render and the film run in Blender on PureTensor's own GPUs; the Bretalon article illustrations are generated with commercial AI image models to our art direction. Nothing comes from a stock library.

An endpaper is the sheet that fixes a book's cover to its pages. It is the first thing you see and the last thing anyone thinks about, and if the binder skimped on it the book falls apart in your hands. We named the studio after it on purpose. The part people notice should be beautiful. The part they never see should hold.

Founded in London in 2026 by Heimir Helgason.

What we make

  • IdentityA name you can say, a mark you can draw, type and colour with a reason, and a voice that survives your first hire.
  • Websites and appsDesigned to the pixel, engineered to the request: booking diaries, storefronts, dashboards, and the plain page that has to work. We measure every one.
  • Print and editorialPapers, reports, brochures and articles that look like the same company as the website. We set the type; we do not export the slide.
  • Pictures and motionRenders and short films made in Blender on our own GPUs, and illustrations generated with AI image models to our art direction, so a picture costs a conversation rather than a stock licence.
  • Hosting and careWhat we build, we run: AWS, backups, monitoring, and a person who answers. From $35 a month.

How a project
moves.

Four stages and no mystery. You know where you are at each one, and what the next one costs.

First.

You write to us

Use the form or email hello@endpaper.ink and tell us what you need. A person usually replies within one UK working day.

Next.

We send a fixed quote

A price and a scope, agreed in writing before we start. The fee for the agreed scope does not change unless you change the brief or ask us to buy something on your behalf.

Then.

We make it

Design, code, copy, pictures, print: whatever the project needs. You see work in progress and steer it. Nothing ships until you approve.

Always.

We keep it running

Hosting, backups, monitoring, and the small edits your plan includes. While your site is on a hosting and care plan, if something we built stops working as agreed, we fix it. There is no other vendor to chase.

Prices on
the page.

We publish website prices because hiding them wastes everyone's time. Identity, print, pictures and motion are quoted per project. Every quote is fixed before work starts: the fee you agree for the agreed scope is the fee you pay, unless you change the brief or ask us to buy something on your behalf.

Guide prices below are for business clients, exclude any applicable taxes, and are shown in £, € or $ by your time zone. Your written quote confirms your fee and billing currency before you commit.
