Start with a 45-minute discovery call

No pitch and no deck. We use the time to understand the problem, tell you what we would do about it, and be honest about whether we are the right team for it.

Tell us what you are working on

We treat everything you send as confidential. No vendor relationships, no referral fees — G5 has nothing to sell you but its own time.

Before you write

Questions we are usually asked first

How do you price engagements?

Fixed scope and fixed price, agreed before we start, with the deliverables named. No open-ended retainer by default.

Who actually does the work?

The partners. There is no pyramid — the person in the discovery call is the person on the engagement.

Do you sign NDAs?

Yes, before any substantive discussion if you prefer. Several of our engagements are published anonymously for exactly this reason.

What is the smallest useful engagement?

A two-week diagnostic: we assess the problem, tell you what needs to change and in what order, and you own the output.

Do you work outside Europe?

We have delivered across five continents. Most engagements involve a corridor into or out of Europe, which is where our depth is.

What happens after delivery?

Full documentation and handover so your team owns the outcome. We stay available, but you are not dependent on us.
