Find the core.Gain the vantage.

Corevanta Advisory is a management consultancy in St James's, London. We help leadership teams see past the noise to the few issues that decide performance — and leave with a plan they can act on.

Why leadership teams call us

Most leadership teams aren’t short of information. They’re short of focus: a shared view of the few things that will actually move the business — and the discipline to leave the rest alone.

Signs it’s time for an outside view

  • Every decision still lands on the same desk.
  • Growth adds people faster than it adds output.
  • The strategy day was good. Monday looked the same.
  • Projects start well and stall in month three.
  • Teams agree in the meeting and disagree in the corridor.
  • Everyone has a dashboard; nobody trusts the numbers.

From noise to a decision, in four moves.

Every engagement follows the same optics. We take everything in, bring it to a point, turn that point into a plan your team can see clearly — and then help you act on it.

  1. 1 · SurveyUsually 2–3 weeks

    Take in the whole picture

    We interview leaders and the people closest to the work, read the numbers you already have and walk the floor. Everything comes in — signal and noise alike.

    • Structured interviews across levels
    • Data you already hold — no new systems
    • Customer and front-line views
  2. 2 · FocusAbout 1 week

    Bring it to a point

    We test what we’ve heard against evidence and reduce it to the few issues that explain most of the rest. If something doesn’t hold up, it doesn’t get through.

    • An issue tree and clear hypotheses
    • Evidence behind every claim
    • Three issues, not thirty
  3. 3 · Plan1–2 weeks

    Turn the point into a view

    With your leadership team we decide what changes, who owns it and how you’ll know it’s working. The result fits on a page.

    • Decisions, owners and dates
    • A 90-day plan and a 12-month line of sight
    • Measures the leadership team will actually review
  4. 4 · DeliverAs long as it’s useful

    Stay until it holds

    We work alongside your people while the changes land — running the programme, coaching managers, adjusting course — and step back once the new way of working holds without us.

    • Programme leadership
    • Coaching for managers
    • Monthly reviews with the board

Who we work with.

Leadership teams at the moment when the way the business was built stops fitting the business it has become.

  • Founder-led companies

    Twenty to a few hundred people, still run the way they were at fifteen. We help founders build the structure that lets them step back without losing their grip.

  • Established mid-sized businesses

    Facing a change that can’t wait: a new market, a new competitor, a new owner. We help you decide quickly and move together.

  • International companies building a UK operation

    Setting up or resetting a London base. We design the organisation, governance and ways of working that connect it to the group.

  • Leadership teams in transition

    After a merger, a new chief executive or a reorganisation. We help the new team agree what matters and how decisions get made.

How we work with you.

Four commitments we make in the first conversation — and put in writing before any work starts.

  • Senior people do the work.

    The people you meet in the first conversation are the people who do the analysis and sit in your workshops.

  • Evidence before opinion.

    Every recommendation comes with the facts behind it — and we tell you plainly what we couldn’t prove.

  • Your team owns the answer.

    We build the plan with your people, not for them, so it survives our leaving.

  • Fixed scope, fixed fee.

    We agree what we’ll deliver and what it costs before we begin. No surprises on the invoice.

Bring us the question that keeps coming back.

A first conversation takes 45 minutes, costs nothing and stays confidential. You’ll leave with at least one useful way to look at the problem — whether or not we work together.
