FAQ

What is a creative collective, and how is it different from an agency?

A collective is made of independent professionals who come together to work on projects. At Tone Def., our project Management team is permanent and our Creative team is independent, when traditional agencies generally keep their entire teams in-house. This allows us to create tailored teams for your unique needs, while keeping costs lean.

Where are you based, and can you work with clients internationally?

Our office is based in London, where Mark lives. Marion is based in France. Our roster is international, so is our capability

Do you do one-off projects or ongoing retainers?

We offer both. Our creative services are tailored to your needs. Whether it’s a launch, brand activation, brand refresh, or ongoing augmentation of your design team, we’re here.

Can you help if I don't know exactly what I need yet?

Absolutely. When you get in touch, we’ll run an initial session to really nail down your challenge and objectives together, before starting any scoping. If further research is required, we offer in-depth strategic research services.

How long does a typical project take?

This can really vary depending on your priorities and the type and scope of project. Do not hesitate to let us know what your constraints and objectives are and we’ll always do our best to match them! However keep in mind that any turnaround shorter than 2 weeks is likely unrealistic.

How do you handle feedback and revisions?

We typically scope for 2 rounds of revisions at each stage of the project (during the conception and delivery phases), which are planned within the timeline. We’re always happy to discuss adjustments should you have specific review requirements.

How do I know if Tone Def. is the right fit before committing to a project?

When you contact us for a project, we offer an initial discovery consultation where you’ll get to meet your core Project team. When you receive a project proposal, you’ll receive an initial timeline estimation, a defined approach, and what you likely won’t get at other agencies: a team composition including designers' portfolios - that we can refine together, so you’re fully on board with how your vision is executed before you sign anything.

The workshop we held with Tone Def. was worth its weight in gold. In just half a day, they helped us distil Rhizo PTX’s complex Power-to-X mission into a clear, punchy brand vision. The proposal they put together was massive in scope and incredibly professional. What really sets them apart is their model, which gives you the focus and agility of a freelancer but with the reliability of a full studio. The strategic clarity they provided acted as a massive catalyst for our internal team. They are truly a top-tier partner for any purpose-driven company.
