Why Consultants choose the ATC

• Work that moves you forward

When a project fits your skills, we’ll get in touch, but you choose whether it’s right for you. That means working on engagements that genuinely build your portfolio and expand your expertise.

• The freedom of contracting without the hidden admin

You’re not left to navigate the freelance world alone. Our Agile Talent team helps you understand freelance regulation and connects you with people who broaden your thinking through our teams and clients.

• Community you can actually feel

Connection shouldn’t disappear just because you’re contracting. From market insights to wellbeing sessions to networking events, you’ll be part of a community designed to make the independent path less isolated and more impactful.

Our culture and values

We have a culture where talented people thrive – where high performance is not just expected but enabled. It’s a culture built on clarity, curiosity, and care. One that challenges us to aim higher, where we’re encouraged to make the most of an abundance of resources to fuel our own development, and where we support each other to grow, learn, and succeed.

Our open and accessible culture means you’ll interact with leaders who are interested in you and everything you bring to our firm. The things that set you apart, we value them. That’s why we give you the freedom to bring your whole self to work and pursue your passions inside and outside of work.
