A UK HubSpot agency
built by software engineers

SpotDev is an AI and digital transformation consultancy that builds real software, working almost entirely with companies that run on HubSpot. We are a HubSpot Diamond Solutions Partner and our 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.

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.

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

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.

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.

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.

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.

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.
