Cohaesus is the Trusted Technical Partner To some of the world's leading advertising & communication agencies

We formed Cohaesus with first-hand experience of just how difficult it is to balance technical resources in the agency environment.

Complex bespoke technology is part and parcel of the digital offering of most agencies now. But maintaining an in-house team to deal with that requirement is usually unsustainable.

That’s where we come in. By bridging the gap between creative and software-engineering, we work with internal teams to architect, deliver, test and maintain reliable, scalable, technical solutions.

This leaves you free to focus on what you do best, with the confidence that when an idea requires tech to make it work, we’re on hand.

Making Tech Work For

Reinventing Freelance

We are Reinventing Freelance.

  If your resources are stretched, we can help. Our carefully selected team of developers can support your in-house team. They’re like freelancers, but with a few important differences:

Risk-free, guaranteed quality

All our developers are full-time Cohaesus staff: trained technical experts that will be a valuable extension to your in-house team. There’s no gambling involved when you use our people.

Flexible resource

We understand agency life, and we realise that sometimes the job doesn’t come in on time. You don’t want a room full of freelancers sitting around with no work to do. For this reason, we’re happy to be flexible and, wherever possible, work around your schedule.

Commitment and accountability

Unlike regular freelance developers, our experts have their boss to answer to. We make sure we place the right person in the right job. After each placement you’ll be asked to rate their performance, helping us to help you.  

Convenient and cost-effective

We’re not a recruitment agency, so there are no agency fees, and no commissions – just a competitive daily rate per head for staff we can vouch for.    

                                 Here’s how Reinventing Freelance works

Support & Maintenance (ASM)

When you are not online you are not in business.

Global online portfolios that cover transactional sites, brand-led sites and campaign microsites all require support and protection every day of the year.
