Our story

After twenty years building apps, we started an agency that doesn’t.

Building apps for the world’s biggest brands showed us what separates the ones that succeed from the ones that don’t. We've built an agency around that single insight.

Why we exist

Most app projects start in the wrong place.

Most agencies sell the full package. Design, build, project management, a stack of invoices that quietly burns through the budget before anyone has tested an assumption.

We Are Affective exists to do the work that should always come first. Research, strategy, psychology-driven design, complete technical specification, then advice on the smartest, most cost-effective way to bring your product to market.

We don’t do the build. We make sure it gets built well.

Simon Lee,

Founder and Strategic Director
The Feel Factor™

Why we built our own framework.

After two decades watching apps succeed and fail, the pattern was always the same. The ones that worked had something the ones that didn’t couldn’t fake. People felt something about them. Trust, calm, pride, recognition. Whatever it was, it was real.

The standard tools of the industry don’t measure that. So we built something that does.

i.

Five dimensions

Trust, delight, anxiety, confusion, and pride. Scored at the start of every project, then again at every milestone, then once more at handover.

ii.

A library of games

Around twenty structured exercises that get past the polite answers. Diagnostic, projective, reflective. Drawn on as the project demands.

iii.

One throughline

The framework runs from research to handover. Every design decision, every recommendation, ties back to it. Nothing happens by feel alone.

What we believe

What we believe.

Six principles shape the way we work, the projects we take on, and the recommendations we make. They were earned, not invented.

Belief 01
The most expensive mistakes happen before a developer writes a line of code.
Belief 02
Design is a behavioural problem, not an aesthetic one.
Belief 03
Honest advice requires no vested interest in the outcome.
Belief 04
Emotional experience is measurable. We measure it.
Belief 05
No developer to recommend, no stack to push, no follow-on to angle for. That’s what makes the advice worth taking.
Belief 06
A small team of senior people will out-think a large team every time.
Clients

Some of the brands we've worked with.

Over the past two decades we’ve worked with the Ministry of Defence, Chanel, Universal Music, Canon, and Lucozade, alongside dozens of funded startups, scale-ups, and challenger brands.

Today we work with founders building their first product, product teams trying to lift retention on their second, and enterprise brands who want their next launch grounded in psychology rather than guesswork.

Where we are

UK based. Working globally.

We’re a UK-based agency working remotely with clients across Europe, North America, and beyond. The thinking we do translates anywhere a product is being built for humans, which is everywhere.

Small by design. Senior by default.

Things worth knowing

Questions we get asked about us.

Affective is the psychological term for emotional response. The dictionary definition is "relating to moods, feelings, and attitudes". It's also a quiet pun on effective, which is the difference our work tries to make. The name is a statement of intent: every product we work on is judged by the emotional response it produces, not the visual one. We chose it because no other name we considered described the work as honestly.

A small senior team including Simon. The people you meet on the discovery call are the people doing the work. There are no junior teams learning on your project, no offshore handoffs, no project managers translating between you and the people thinking. We stay deliberately small because the work doesn't scale well by adding bodies. It scales by adding judgement.

Founders building their first product who know they'll only get one chance to launch it. Product teams trying to lift retention on a second or third release. Enterprise brands who've decided the next launch needs to be grounded in something more than instinct. The common thread is that the people we work with are usually treating the project seriously and want their thinking to match.

Anyone who wants the cheapest possible foundation work, anyone who wants us to validate a decision that's already been made, anyone whose timeline doesn't allow for the research to actually shape the design. We'll usually spot the mismatch on the discovery call and say so.

The collective experience runs to over two decades, all of it in mobile and web app design at the brand-and-enterprise end. Past clients include the Ministry of Defence, Chanel, Universal Music, Canon, and Lucozade, alongside dozens of funded startups, scale-ups, and challenger brands. We Are Affective is what happened when we distilled everything that work taught us about why apps succeed or fail into a single, focused practice.

Yes, it's ours. The Feel Factor draws on established work in behavioural psychology and emotional design, but the framework, the five dimensions, the library of structured exercises, the way it threads through a project from research to handover, is something we developed over years of practice. It's the discipline behind every project we run, and we're publishing the full thinking as a book later this year.

Selectively. Most client projects are confidential, and we won't break that to win a new pitch. The work that does end up public, the writing, the talks, the upcoming book, focuses on the methodology and the patterns we see across projects, not on individual cases. If you want to see how we think, that's where to look.

It means we don't take referral fees, kickbacks, or commission from any developer, agency, or technology provider. We don't have a preferred build partner, a stack we're trying to sell you, or a follow-on contract waiting on the other side. When we recommend an approach, the only thing shaping that recommendation is your project. The independence is a structural choice, not a marketing claim.
