Accountable delivery partner. Relentless value realisation.

Keep the responsibilities you want. We build, run and evolve the rest.

Software and AI delivery, measured on the value it realises, not the hours it bills. Behind consulting firms and integrators, under their name, and alongside enterprise teams.

Measured on value, not headcount. That is what we optimise for.

One Unified Management Model™ runs every work package, whoever does the work.

Your clientSees your firm throughoutWorks with your firm from brief to sign-off and sees your brand on every deliverable.

Three ways to start.

Every engagement starts with the business objectives, then one defined first package, often a diagnostic or an assessment, with scope and acceptance agreed up front. Here are three. Point at one, or tap it, to see what it involves.

Express Audit

  • About one week
  • From US$2,500, fixed

For an AI application that is already live.

We need
Read-only access to the code and the live application
You get
A risk register ranked by severity, and a remediation plan with a cost estimate
See the Express Audit

Package scoping

  • Free in joint pre-sales
  • Fixed or capped price

For consultancies and integrators with a bid or a client brief.

We need
The brief or the bid, the client’s constraints and the deadline
You get
A named team, the scope cut into work packages, and a written acceptance test for each
Send us the brief

Orchestration Diagnostic

  • Two days
  • Fixed fee, quoted in the first call

For enterprise teams running work across several suppliers, locations or AI tools.

Who takes part
Your team and your suppliers
You get
A written output and a sized first work package: a decision point, not a proposal
Ask about the diagnostic

Why partners hand us the work.

Four outcomes decide it. Winning the work is one problem. Delivering it, and proving the value, is another. Point at an outcome, or tap it, for the proof.

Full oversight, through accountability and transparency. You make the calls. One party answers for the result, and you see every package in one view.

  • Nessoris signs and answers for its delivery partners, and carries professional indemnity insurance.
  • One shared view of every package: milestones, status beside trend, the top risks with their mitigation, and the benefits.
  • Decision rights, approvals and quality checks visible to you and your client, with senior leaders you can reach directly.
  • You choose, layer by layer, what stays with you, and the split can change as you grow.
How we stay accountable

Value realisation, through baselines and benefit owners. You see the gain against a baseline set before we start, measured and pursued package by package.

  • Business objectives and a baseline agreed before the first package, so the gain can be shown, not claimed.
  • Every benefit has an owner in your business who signs it off, and every package is traced to one.
  • Every package accepted against a written test, whoever did the work: your people, our specialists, partners or AI agents.
  • Value reported from your own systems wherever we can, and reviewed at agreed points after go-live.
How we realise the value

Compounding capability, through knowledge you keep. Each package starts from what the last one learned, and you keep it all.

  • Code, documentation and the delivery record follow your contract, so the knowledge stays with you.
  • The content is yours, and the method can be too: it can transfer to strengthen your own operating model. Nothing learned on your work is reused for another client without your consent.
  • Every package recorded, so the next one starts smarter.
  • Transfer terms set at the start, so leaving is never a negotiation.
How knowledge compounds

Strategic agility, through scalable capacity and on-demand capabilities. You can say yes to the next bid or programme without hiring for it.

  • Specialists picked per work package from a multi-shore network, scaled in and out as your portfolio moves.
  • Delivery partners assessed before they are ever on your work.
  • A named team in your bid, and the people who shape it stay on the work.
  • No bench to protect, and a stop point after every package.
How we scale with you

What we are not, and what we are instead.

  • Not just staff augmentationA defined result, and we answer for it
  • Not a competing integratorBehind you, never around you
  • Not just a one-off projectOne team from the first package to year three
  • Not cheaper headcountJudged on the cost of the outcome, not the day rate

Keep what you want. We cover the rest.

Every client keeps something different. Choose, layer by layer, what stays with you, and see what we take on.

Start from a typical split

Tap any layer to switch it between You keep and Nessoris covers.

You keep three layers. Nessoris covers three, under one management model, and the split can change as you grow.

Under your name: your client sees your firm throughout.

Whatever you keep, we fill the gaps around it, with one point of accountability across every layer we cover.

See every service, layer by layer
  1. 1Solution strategy and roadmap

    What gets built, why, and in what order, to ensure a return on the investment.

    A product owner who carries the roadmap from concept into run, so it gets delivered.

  2. 2Architecture and design authority

    The boundaries every supplier builds within, to ensure the pieces fit and the design holds as suppliers change.

    Design decisions recorded and carried into build, fitted to your estate.

  3. 3Change and adoption

    Training, communication, process change and benefits tracking, to ensure the system is used and the benefits arrive.

    We lead adoption with your people, with specialist partners where needed, and track the benefits until they are realised.

  4. 4Programme and service management

    Plans, suppliers, risks and service measures across the work, to ensure on-time, on-budget delivery and one service across all your suppliers.

    One programme and one set of measures across all your suppliers, without a large integrator's overhead.

  5. 5Build and deliver

    Working software, tested and accepted, to ensure what ships is what was asked for.

    Working software, priced per work package against an acceptance test agreed up front.

  6. 6Run and evolve

    The live system after go-live, to ensure it stays stable and keeps returning value.

    Systems run and improve at a known monthly cost, with a clean way out.

Two ways to work with us. One way of delivering.

For consultancies and system integrators

Behind your engagements

We deliver behind your client engagements, under your name. You keep the client relationship and design authority; we take over a layer only when you step back, never instead of you.

For enterprise teams with a digital or AI programme

Directly for your business

We bring order across your suppliers and supply more when you need them, and we build and run a dedicated capability unit of 10 to 50 people around the responsibilities you choose to keep, built to be handed over on terms set at the start.

Behind your engagements, four ways in. You can stop after any of them.

Offer

You define the offer. We test whether it can be delivered, by whom and at what cost.

Bid

You lead. We bring a named team and write parts of the proposal.

Design

You agree the design. We cut it into work packages, each with a defined scope, an agreed price and an acceptance test.

Build and run

We build the packages, you integrate and accept. We stay for fixes, maintenance and further development.

Your project ends in 16 weeks. Your technology doesn't.

Value leaks at every handover: from roadmap to build, from build to run, from one vendor to the next. We stay accountable across all of them and leave an installed capability, not a finished project. The aim: the return still comes in year three, at the same cost of change.

See the six stages and how each is priced

What we aim for in year three

  • The return holds. The benefits in the business case are still being delivered.
  • The cost of change stays flat. The next comparable change costs about what the last one did. Every package is recorded with its effort, so you can check it.
  • The roadmap is owned. Someone accountable decides what comes next.
  • The knowledge stays put. A departure does not reset the programme.

Value you can see, not activity reports.

Every benefit has a baseline, an owner in your business and a report every period, before, during and after go-live, from your own systems wherever we can.
