01 / Services

Four things, done properly.

Certified Umbraco partners too. It's a practice, not the whole brand. Umbraco →

02 / Outcomes

The work stays white-label.
The results don't have to.

We can't name the clients. That's rather the point.

74%

Faster loads and search — national infrastructure group

A careers platform rebuilt on the client's own infrastructure, with Examine and Azure AI Search doing the heavy lifting.

11 yrs

Rob's web development experience

Since 2015, Rob has built for construction, legal, property, retail, marketing technology and consumer brands. Nearly all of it delivered under somebody else's name.

Two engagements, in shape

Careers platform — national infrastructure group

Recruitment brought onto one system

A careers platform rebuilt on the client's own infrastructure, with Examine and Azure AI Search behind it and custom API connectors feeding vacancies straight from the internal system. Recruiters manage roles in one place and the site ingests and presents them, with routing simplified so a position goes live without anyone rekeying it.

OneSystem for every vacancy

Replatform — international law firm

WordPress to Umbraco, multilingual and multi-region

A full content migration off WordPress for a multilingual, multi-region estate, with staff data pulled in securely from third-party APIs and Azure AI Search powering discovery across it. Delivered beneath a white-label design partner, on top of the agency we were already working through: two layers of brand between us and the client.

EarlyDelivered ahead of schedule

And three more, briefly

Greenfield replatform — listed property group

Fixed-price rebuild, designs built faithfully

A full greenfield project at fixed price alongside a partner agency: their designers' work built to the pixel, the stack modernised, and the estate replatformed onto Umbraco with performance and SEO both up on what it replaced.

Greenfield platform — creator marketing

Creator analytics, with AI throughout

A platform that analyses creators for trends so brands can build campaigns around the right ones. AI runs through it: automated content review, scoring and metrics. Built from scratch alongside both the partner agency and the end client.

Campaign build — national consumer brand

Reusable HTML banners at campaign scale

A banner system built to be assembled rather than hand-coded, so a very large marketing campaign could produce variants, test them and iterate without rebuilding each one from scratch.

04 / How it works

Four steps, no account managers.

Rob scopes the work and stays involved in delivery. Here is how an engagement takes shape.

  1. 01

    Understand your pipeline

    A short call about your clients, your stack and where you're stretched.

  2. 02

    Shape the engagement

    A package that fits: a project, a retainer, or seats on your team.

  3. 03

    Integrate with your team

    Your tools, your standups, your ticketing. We fit around how you work.

  4. 04

    Deliver under your brand

    Shipped, supported, invisible. Your clients see your agency at its best.

All of it runs through our client portal: requests, acceptance criteria, sign-off and agreed costs in one place, instead of buried in an email thread. Your accounts are set up at the start of the engagement.

05 / Capacity & rates

What it costs, and when we can start.

No rate card games and no discovery phase you pay for. Three shapes, and you pick the one that fits.

Currently taking new projects, typically 2–3 weeks to start

Project
Fixed price, quoted after a free scoping call. You get one number, not a range that drifts.
Support retainer
From £120/month for monitoring and patching. Plans with retained senior developer hours from £500/month.
Seats on your team
£80/hour for senior developer time, discounted for retainer clients. Your tools, your standups, your ticketing.

Azure-first hosting is sized and quoted per estate, from your real traffic figures. Every engagement starts with a free scoping call. If we are not the right fit, we will tell you on that call.

06 / Questions

The things agencies ask first.

What does white-label development mean in practice?
For agency engagements, the work stays under your brand. Our developers use your tooling and join your standups; we speak to your client only when you introduce us as part of your team. Deliverables, release notes and handovers carry your name. Most of our partners' clients have never heard of Helitz, which is the point.
Do you work with in-house teams as well as agencies?
Yes. In-house technical teams hire us for senior .NET or Umbraco capacity without adding headcount. We use their existing processes and report to their technical lead, just as we do with agency partners.
How do you charge: fixed price or time and materials?
Both, depending on what suits the work. Clearly scoped projects are fixed price after a free scoping call; Umbraco upgrades follow a free health check. Support starts at £120 per month for monitoring and patching, with retained senior developer hours on plans from £500 per month. Ad hoc development is £80 per hour, discounted for retainer clients.
What technologies do you specialise in?
Current LTS releases of .NET for backend and API work, React and Next.js for frontend, and Umbraco for content management. We host Azure-first, with AWS where a client's estate already sits there. We deliberately do not spread across more stacks than we can keep genuinely senior in.
How quickly can you start?
A new engagement can typically start in two to three weeks, sooner for retained partners with existing capacity. We will tell you honestly on the first call whether we have the right people free. We would rather decline than take work we cannot staff properly.
How do we keep track of what's in progress?
Every Helitz engagement runs through our client portal. You raise requests, agree acceptance criteria and sign off delivery there, with scope, cost and status in the same place. Changes are raised and priced there too, with a record of what was agreed. We set up your accounts at the start of the engagement.
What happens if the scope changes mid-project?
A mid-project scope change goes against the signed-off acceptance criteria, and we tell you whether it is rework on our side or new work. If it is new work, you get a price and approve it before we build anything. Nothing gets quietly added to an invoice.
Where is Helitz based?
Helitz Digital Ltd is a UK company based in Stoke-on-Trent, Staffordshire, registered in England and Wales under company number 13261365. Our engineers are UK-based and work UK hours.
