Most agencies haven't launched a product, grown a company, or seen one through to acquisition.
We have. That's the difference.

Howwe work

How we think about craft, founders, and shipping work that holds up.

Six principles we don't negotiate on. They shape how we work with you and what you get at the end.


01

We build things, we don't just design them

Every project gets real development thinking from day one. Design and engineering in the same room, not thrown over a wall.


02

Founder first

We've been where you are. We skip the hand-holding and get into it.


03

Small team, full ownership

You work with the person doing the work. No account managers between you and the output.


04

Honest over impressive

We'd rather tell you something won't work than charge you to find out.


05

Speed without shortcuts

Fast is only good if it's also right.


06

The work is the pitch

No inflated case studies. Come see what we've actually built.

Great people,great projects

One studio.Real work.No layers.

Meet our incredible team, where skills blend with empathy and a sense of humor.

{ Make no mistake—we take our work very seriously. }


Ollie Darby
Ollie
Founder

Circle Square was built on a simple frustration: most agencies make things that look good in a deck and fall apart in production. We've seen it from both sides — as clients, and as founders trying to ship something real.

We're a development studio with a genuine design sensibility. That combination is rarer than it should be. It means every project gets the full picture: brand thinking, visual craft, and the technical execution to match.

We're not the biggest studio. We're not trying to be. We're trying to be the one that does the work properly — and that you'd actually want to work with again.

Approach

{ Four disciplines that turn ambition into something people actually use }

01

BrandStrategy

The story your company tells before anyone meets you. We get into the business, understand the positioning, and build something that holds.

02

VisualIdentity

Visual systems that scale — from pitch deck to production, from launch day to Series A.

03

Website

Not templates. Not page builders. Real sites, built to perform and built to last.

04

Product

Digital products that start from how people actually use things — not how we want them to.

Selected Case Studies

A few reference case studies we like — clear thinking, sharp design, and work that holds up. Not a client list.

Collaboration is everything. We don't work for you and you certainly don't work for us. We work together — with the shared vision of building what matters.

FAQ

Eight things worth knowing before we work together.

  • Mostly early-stage startups and founders building something for the first time — or rebuilding something that didn't work the first time. We've been through it ourselves, so we understand the constraints.

  • We're flexible. Sometimes it's a full brand and website. Sometimes it's one component that's holding everything else back. Tell us what you need and we'll be straight with you.

  • It depends on the scope, but most projects start with a brief discovery session — paid, focused, and designed to get us both clear on what actually needs doing.

  • By project, not by the hour. We scope it properly upfront so there are no surprises on either side.

  • Yes. If you've got something that's working, we build on it. If it isn't working, we'll tell you.

  • Fully. We've worked with founders across the UK and Europe. If you're local and want to meet, great — but it's not a requirement.

  • Front-end: Next.js, React, TypeScript. We pick the right tool for the project rather than defaulting to one stack.

  • Occasionally we co-build with early-stage founders — equity arrangements, sprint-based partnerships, or acting as a technical co-founder for the first stretch. It's selective. If it sounds relevant, mention it when you get in touch.
