The work.

A few highlights from the client work, for Radioplayer, British Airways, Microsoft, Time Out and the BBC.

Standout work

40|30 at the Gherkin.

Searcys ran the restaurant and bar at the top of 30 St Mary Axe, London’s highest venue. We built its website around a full-screen film that took you up there, and showed the place in use in a way a site visit never could.

The film, 2 minutes. Shot inside the Gherkin in 2008, with an original score cut to the final edit.
  • Winner. FITC Award for Motion Graphics, Toronto, 2009. Shortlisted alongside Coca-Cola and Warner Brothers.
  • Nominee. The Webby Awards, 2009, chosen from nearly 10,000 entries.
  • Featured. MOLUV Featured Site Award.

Video newsletters

February 2013. The end of the first merged month of Codegent and Thin Martian.

“We don’t rehearse and we rarely start again if one of us messes up.”

David Hart, Third Thursday: is it worth it?, November 2011. He worked out each newsletter cost about £1,200 to make, sent to just under 1,000 people, and asked: “Would we be better off just buying everyone a sandwich?”

The offices

London and Bangkok.

Three studios in London, two in Clapham and then Old Street, and three in Bangkok.

Clapham, 2006. The top floor of the Plough Brewery, a converted brewery at 516 Wandsworth Road. “High, beamed ceilings and views out towards Battersea Power Station.”

The makeover, 2009. A glass meeting room, leather sofas and a drinks fridge “for… erm, drinking”.

Hats on. Clapham, January 2010.

Bangkok.

Bangkok began in 2004 too, in Luke and Khum’s house, with the first little office and the first staff. It moved into a proper office in 2009, and by that December there were 30 people across London and Bangkok.

The Bangkok team at their computers, one smiling at the camera
The Bangkok team. At their desks.

2010. A new home for the Bangkok office. Luke moved there for good, and a small team of developers there started building web apps.
The Bangkok team working on laptops on a terrace in Chiang Mai
The floods, 2011. When Bangkok flooded, the team packed the office into a box and decamped to a reserve in the mountains near Chiang Mai. Nor, a designer on the team, drove through the floods in her pickup to get people to the airport. Luke called it “the best office I’ve ever had”.

Old Street.

In 2012 Codegent bought Thin Martian and moved into its office: a converted Victorian warehouse at 32-37 Cowper Street, right beside Silicon Roundabout, with both teams in one open-plan space.

437 posts. 34 bylines.

The blog ran from 2005 to 2017, and the studio wrote it, not just the founders. “We actively encourage everyone in the agency to write,” David wrote in 2011. These are the people who did, and how many times.

Codegent Labs

Where ScreenCloud began.

What it became

“Overall, it’s safe to say that Codegent is a pretty decent place to work!”
