01 — Product intent
What it is for, and who uses it
Skip the feature list. Tell us the job the product does, whether it is a customer-facing app, an internal tool, or a game, and the person you picture on the other end of it.
Say hello — London studio open
Tell us about the project you are building
If you have a brief, a question, or a project that is stuck, this is the place to send it. Every message goes to one inbox and is read by people who work on builds, not a sales desk.
If you are not sure whether your project fits, send it anyway. A short reply either way is quicker than a discovery meeting.

The inbox the studio actually works from
A short brief beats a long one
How to send a useful brief
Tell us what the product is for, who uses it, which platforms matter most, and what is already built. Everything else is a bonus.
02 — Platforms & state
Which platforms matter, what exists
iOS, Android, PC, console — say which ones lead. Then note what is already built: a Figma file, a half-finished prototype, a Notion doc, or just the idea on paper.
03 — Deadline & sketch
Any real deadline, any rough sketch
If a deadline is tied to something real — a launch window, a funder, a partner — say it. If you have not written anything down yet, a paragraph works. We have built scopes from worse.
The mailbox is [email protected]. If you would rather talk first, ask for a call in the message and we will set one up.
Book a 30-minute callA real reply, from builders
What happens after you send
Every enquiry gets a first reply within two working days when the studio is open. That reply will either ask two or three follow-up questions, suggest a call, or tell you honestly that we are not the right fit and why.
If it is a fit, the usual next step is a thirty-minute call. No pitch deck, no sales script — a conversation about the product, the platforms, and whether we can actually help.
The scoping week, if it follows
Runs for a week and produces a written scope you own whether or not you build with us. Scope fees are fixed, small, and credited against the build if you continue.
We do not add enquiries to a mailing list. If you want to hear about new work, that is a separate sign-up.

A working studio, not a lobby
Visiting the London studio
The studio is based in London and we are happy to meet in person for scoping weeks or milestone reviews when that is useful. For most other conversations, a call is quicker and easier for everyone.
If you are planning to visit, message first and we will confirm a time. The studio is a working space and we are usually heads-down during the day.
Partnerships, pitches & press
Routed to a slower queue, on purpose
If you are a studio looking for a co-development partner, say so in the subject line. Those messages get routed to a different queue and usually get a reply within a week, since they need a slower look.
Press enquiries and pitch decks for original IP support are welcome. We read everything; we do not always reply to everything if it is clearly not a fit. For recruitment, our own hiring goes through a separate channel and is listed on the site when roles are open — speculative CVs are read but not always answered.
The brief form
Send it without opening an email client
The contact form collects your name, email, and message so we can reply. Nothing else is stored, and nothing is shared outside the studio. Full details on how we handle personal data sit in the privacy policy, which is linked from the footer on every page.
The studio at work
The Clerkenwell desk at 4pm, painted — lamp on, keyboard waiting, the studio usually heads-down during the day.
Saves both of us a call
What we cannot help with
We get messages for things outside our work and it saves time to say which.
- We do not run global live-ops teams at scale.
- We are not a staffing agency placing contractors elsewhere.
- We do not take on projects where the client wants no involvement until launch.
For anything that does not fit, we will usually point to what would. That is the honest answer, and it is quicker than a call that goes nowhere.
