Project Enquiry FAQs

Useful answers before you start a project enquiry.

We review the written context first so we can understand the problem, timing, budget range, capability fit and likely route. The next step may be a written follow-up, a short questionnaire, a diagnostic or scoping phase, a scoped recommendation, a qualified call or another route.

Share what you are trying to build or improve, what is not working, what success would look like, your timing, budget range and decision process. Links to your website, product, brand, analytics, campaign or sales materials are useful if available.

No. A clear written summary is enough to start. If the project is not fully defined, we can help identify whether the right first step is clarification, diagnostic work or a more focused scope.

Choose the closest fit: Strategy & Proposition, Brand & Creative Systems, Digital Experience & Product, Campaigns, Content & Demand, or Growth Intelligence & Optimisation. If you are not sure, select “Not sure yet” and explain the problem in your own words.

Possibly. We start with written context because it makes the first response more useful. After review, we may continue in writing, ask for more detail or arrange a qualified call if that is the best way to confirm objectives, decision process and scope assumptions.

A budget range helps us recommend the right route and avoid shaping work around the wrong level of scope. It is not treated as a final fee; it helps determine whether the next step should be a focused diagnostic, scoped project or staged programme.

5sum is best suited to work where proposition, brand, digital experience, product, content, campaigns or optimisation need clearer direction, stronger systems and better proof. We are not usually the right fit for isolated production tasks without strategic context.

5sum is led by a senior core team. Where the scope requires additional design, content, development, media or technical capability, trusted specialists may support defined parts of the work under clear direction and review.

Only share what is useful at enquiry stage. We keep access limited, avoid unnecessary sensitive detail and agree any confidentiality, permission or proof requirements before materials are used in project work or public outputs.

Still have a project question?

If the FAQs have answered the basics, share the project context and we’ll advise the most suitable next route.
