What we do

What a HubSpot partner built by engineers does

Four service lines, delivered by one in-house engineering team. Most engagements start in one and expand into another once the system is working.

HubSpot development

Custom apps, UI extensions, serverless functions, coded workflow actions and portals, written and maintained by our own engineers.

  • Custom-coded workflow actions
  • UI extensions and serverless functions
  • Marketplace app development

Integrations and data

Two-way integrations between HubSpot and the systems you run on, plus CRM migration, deduplication and data engineering.

  • ERP, finance and operational systems
  • CRM and data migration
  • Real software, not brittle middleware

AI implementation

AI built into the systems you already run, with scoped access, a human approval step where it acts on something that matters, and an audit trail afterwards.

  • OpenAI Select Partner
  • Certified in the Claude Partner Network
  • HubSpot Breeze and Agent Hub

Websites, SEO and AEO

HubSpot CMS websites designed and built by the same team that connects them to your CRM, with technical SEO and answer-engine visibility included.

  • Design and development
  • CRM-connected, not brochure-ware
  • Technical SEO and AEO

How an engagement runs

The same sequence on every project, whether the work is an integration, an AI build or a website. Scope is fixed before build starts, so the price is agreed before anyone writes code.

  1. 01

    Diagnostic first

    We look at your HubSpot portal, your data and the systems around it before proposing anything. Sometimes the finding is that you do not need us to build.

  2. 02

    Fixed scope

    The diagnostic becomes a written scope with deliverables, assumptions and a price. You approve the scope before build starts.

  3. 03

    Build

    Our in-house engineers build it, in a test environment first, with code review and a rollback path. You see progress every week.

  4. 04

    Handover and support

    Documentation, training for the people who will run it, and a support arrangement if you want one. The system stays yours.

Choosing a HubSpot partner in the UK: what the tier tells you and what it does not

Every firm on this page's competitor lists is a HubSpot Solutions Partner. HubSpot ranks its partners in tiers, Gold, Platinum, Diamond and Elite, on the revenue a partner manages and sells and on how well its clients are retained. SpotDev is a HubSpot Diamond Solutions Partner. That tells a buyer we run a lot of HubSpot portals and that the clients stay. It does not tell you whether we can write the integration, the custom object model or the AI agent you need, because tier measures commercial scale rather than engineering capability.

For technical work, three things say more than the tier:

  • Accreditations. HubSpot awards these after reviewing delivered work. SpotDev holds the Custom Integration Accreditation and the Onboarding Accreditation. Ask any HubSpot partner which accreditations it holds and what work HubSpot reviewed to award them.
  • Who does the work. Ask whether the people who scope the project are the people who build it, whether they are employed or subcontracted, and where the code lives when the engagement ends. Our engineers are in-house and the code is yours.
  • Verified reviews. The HubSpot Solutions Directory publishes reviews that HubSpot verifies against a real client relationship. SpotDev is rated 5.0 across 38 reviews there. Read the reviews for the type of work you need, not the average.

If the work is campaigns, content and reporting inside HubSpot, a HubSpot marketing agency is the right partner. If HubSpot does not connect to something, does not do something, or does not hold the data you need, you need a partner that builds software.

Choosing a UK HubSpot partner

Everything you need to know about our services

What kind of HubSpot partner is SpotDev?

SpotDev is a HubSpot Diamond Solutions Partner and a UK HubSpot agency built by software engineers: an AI and digital transformation consultancy that builds real software, working almost entirely with companies that run on HubSpot. The team is made up of software engineers rather than campaign managers, so the work is custom development, integrations, AI implementation and websites rather than content retainers.

Is a HubSpot partner the same as a HubSpot agency?

Usually, yes. "HubSpot Solutions Partner" is the formal name for a firm in HubSpot's partner programme, and most partners describe themselves as HubSpot agencies. The distinction that matters is what the partner does: some run marketing and sales campaigns inside HubSpot, some implement and configure it, and a smaller number, including SpotDev, build custom software around it. Check the partner's tier and accreditations on the HubSpot Solutions Directory, then check what kind of work the reviews describe.

How should we choose between HubSpot partners?

Start with the work, not the tier. Write down what HubSpot needs to do that it does not do today, then ask each partner to describe a comparable project, who built it, and what happened after handover. Check accreditations, which HubSpot awards after reviewing delivered work, and read the verified reviews on the Solutions Directory for that type of project. Ask for a fixed-scope price rather than a day rate, and ask who owns the code. A short paid diagnostic is a low-risk way to test a partner before committing to a build.

What does HubSpot Diamond Partner mean?

HubSpot ranks its Solutions Partners by tier, based on the revenue a partner manages and sells and on customer retention. Diamond sits above Gold and Platinum and below Elite, and puts a partner in the top few per cent of the programme worldwide. It is a measure of scale and retention, not of engineering ability, which is why the accreditations below matter more for technical work.

Which HubSpot accreditations and certifications do you hold?

SpotDev holds HubSpot's Custom Integration Accreditation and its Onboarding Accreditation, both awarded after HubSpot reviews delivered work rather than after an exam. We also hold Cyber Essentials Plus, are an OpenAI Select Partner and are Certified in the Claude Partner Network. Our rating on the HubSpot Solutions Directory is 5.0 across 38 reviews.

How is this different from a HubSpot marketing agency?

A marketing agency runs campaigns inside HubSpot. We build the software around it: integrations with your ERP or finance system, custom objects and workflow actions, customer portals, AI that acts inside your CRM, and the website that feeds it. If your problem is that HubSpot does not connect to something, does not do something, or does not hold the data you need, that is engineering work.

Where is your team based?

We are an in-house, fully remote engineering team with no office. Most of the team is in the UK, in Bath, Bristol, Cheltenham, Cheshire, Leeds, Sunderland and Wales, with engineers in South Africa and Romania and a designer in Italy. Our registered address is Office 11, 3 Edgar Buildings, Bath BA1 2FJ. We work with clients anywhere in the UK and travel on-site when it helps.

How do you price HubSpot work?

On fixed scope, not day rates. A short diagnostic establishes what the work actually involves, and that becomes a written scope with deliverables and a price you approve before build starts. Prices depend entirely on scope, so we quote per project rather than publishing a rate card.

What size of company do you work with?

UK B2B companies from around £3m in revenue upwards, with no upper limit, that hold an active HubSpot subscription and have outgrown configuration and no-code workarounds. Below that, the cost of custom engineering rarely pays for itself and HubSpot's own tooling is usually the better answer.

How do we start?

Request a quote if you know what you want built, or start with a diagnostic if you want an assessment of the portal and the systems around it first. Either route puts you in front of the engineers who would do the work.
