Founder

Note from the founder

With over 14 years in visual storytelling, my work sits at the intersection of cinematic craft and commercial precision. I believe video is more than just content. It is perception, positioning, and long-term brand equity.
Throughout my career, I have had the privilege of working with globally recognized names such as ASOS, Hia Magazine, EYC, and Bicester Village, delivering high-caliber campaigns in competitive markets. Collaborating with brands of that scale refined my approach. Every frame must feel intentional, elevated, and strategically aligned.
As demand for my work expanded, I built a carefully selected team of creatives who share the same attention to detail, discipline, and performance mindset. We approach every project with the standards of a luxury campaign and the strategic thinking of a growth partner.
While many production companies focus solely on visibility, my focus has always been different. I create refined, performance-driven visual campaigns designed to strengthen brand perception and generate measurable business impact.

FAQ

Your questions answered.

Everything you need to know about partnering with us. Have more questions? Book a free call and we’ll guide you through the process.

What exactly is branded content, and how is it different from a normal ad?

An ad interrupts; branded content earns attention. It’s storytelling built around your brand’s world, the kind of film, series, or social-native piece people choose to watch. The commercial intent is still there, but it’s carried by narrative, not a hard sell. That’s why branded content consistently outperforms traditional ads on watch time and shareability.

Do you handle branded content video production in London only, or do you work internationally?

We’re an East London studio, and London is home turf, crews, locations, and talent networks we know inside out. But our productions have run internationally, and our client work spans global brands. If the story needs to be shot elsewhere, we go elsewhere.

What does a typical project cost?

Honestly: it depends on scope, and anyone quoting you a flat rate before a conversation is guessing. A social-native content package and a multi-day luxury brand film are different animals. What we commit to is transparent, line-itemed budgets agreed before production starts, no surprise invoices in post.

How long does a production take from brief to delivery?

Most projects run 4–8 weeks end to end: discovery and creative development, pre-production, shoot days, then edit and delivery. Tight campaign deadline? Tell us upfront, we’ve turned projects around faster when the brief demands it, without cutting the corners that show on screen.

We already have an in-house content team. Where do you fit?

Alongside them, not instead of them. Many of our longest partnerships are with in-house teams who need cinema-grade production capability, overflow capacity, or a creative partner for the campaigns too big to handle internally. Your team keeps the brand knowledge; we bring the firepower.

What do we actually get at the end of a project?

Master films plus channel-native versions, cutdowns, verticals, square crops, colour-graded, mixed, and delivered to spec for every platform you’re publishing on. You own the deliverables. No hostage-taking on raw files without prior agreement, no licensing ambushes.

How do you measure whether the content actually worked?

Before we shoot anything, we agree what success means, views, watch time, engagement, conversions, or brand lift, so we’re all measuring the same thing. After delivery, you get performance reporting against those numbers, not a vanity-metrics dump. Across our client work, campaigns average 38% growth, but the number that matters is the one tied to your objective, defined before the cameras roll.

How much of our time will a project take?

Less than you’re bracing for. You’re essential at three points: the discovery conversation, creative sign-off before production, and final approval on delivery. Everything between those checkpoints, logistics, crew, locations, edit rounds, is our job to run, with updates that take minutes to read, not meetings that eat your afternoon. In-house teams work with us precisely because we don’t become a second job.
