Our overview

Fuelius is a UK-based digital agency that helps B2B and SaaS companies improve how they attract, convert, and retain customers.

The team focuses on CRM implementation and optimization, website design and development, and ongoing marketing support. They work with platforms such as HubSpot and modern CMS tools to build sites, automate journeys, and connect data across sales, marketing, and service.

Clients choose Fuelius for its platform know-how, structured delivery, and ability to link strategy with day‑to‑day execution. Typical projects include CRM migrations, integrations, lead generation, and marketing automation. Their approach is collaborative, goal‑driven, and focused on measurable outcomes.

What does Fuelius do?

Fuelius is a HubSpot agency based in Chester, in the United Kingdom, that builds websites, sets up CRMs and runs marketing for B2B and SaaS companies. Its website tagline is “Fuel your business growth”, and it puts its team at 80+ people.

The services its website lists fall into these groups:

  • CRM: HubSpot CRM enablement, CRM migrations and integrations
  • Websites: website development and CMS implementation
  • Marketing: inbound marketing, digital marketing, paid media and SEO
  • Sales and revenue operations: sales enablement and RevOps

Its profile describes the common thread as connecting data across sales, marketing and service, so that the website, the CRM and the automation work as one set-up.

Who does Fuelius work with?

Fuelius’s website mentions SaaS, and lists professional services as an industry. The clients it names are a broad mix: GJW, Caesarstone, Moda, Aspinall, Emirates, Emirates Old Trafford, Fusion21, iVendi, Orega, Credera, Lowell, Moda Living, Health Shield and HSFC.

Few of those are software companies, so SaaS buyers should ask for examples closer to their own model. The profile points to scaling mid-market and enterprise companies with real operational complexity, such as weak reporting, disconnected systems and manual workarounds, over early-stage teams.

How does Fuelius work?

Fuelius works mainly in HubSpot. Its website describes it as a HubSpot Elite Solutions Partner and a HubSpot User Group Leader, and mentions 200+ HubSpot certifications across the team. It is also a Google Partner and an Umbraco Partner, which matters for companies that run an Umbraco website alongside HubSpot.

Its profile calls the delivery structured and collaborative, with typical projects including CRM migrations, integrations, lead generation and marketing automation. On the marketing side, that means lead scoring and nurture workflows built in HubSpot across marketing, sales and service teams.

The website also mentions 100+ five-star reviews.

What results does Fuelius’s website point to?

Fuelius publishes case studies on its site. The ones we found on the pages we read are:

  • a HubSpot sales strategy case study for Moda, a build-to-rent operator
  • “Creating a household name with Caesarstone”
  • “Building Fusion21’s lead machine with a new HubSpot CMS website”
  • a case study for the Payment Systems Regulator

None of those is a SaaS company.

What to ask Fuelius before you hire them

  • Which SaaS companies have you taken through a HubSpot migration, and can we speak to one?
  • Who would run our account day to day, and how senior are they?
  • Do you build sites only on HubSpot CMS and Umbraco, or on other platforms too?
  • How do you scope a CRM project before it starts, and what does it include?

Where Fuelius ranks

The top lists they are on, and what we said about them on each.

  • Ranked #6

    Top HubSpot Agencies

    Best for: HubSpot RevOps and integration by an Elite partner

    • Elite Partner, in growth marketing since 1998
    • RevOps and 100+ CRM implementations
    • Umbraco Gold as well as HubSpot
    Read our review

    Fuelius is a Chester-based HubSpot Elite Partner, placing it in roughly the top 1% of HubSpot's global partner roster, and it has been in growth marketing since 1998, long before HubSpot existed. That history shows in the positioning: the team focuses on the operational friction that builds up as companies scale, such as weak reporting, disconnected systems and manual workarounds. Services span CRM implementation, RevOps, systems integration, marketing automation and website development, and Fuelius is one of only three UK agencies to hold HubSpot's Onboarding Accreditation, with over 100 CRM implementations completed.

    An unusual strength is its Umbraco Gold partnership, which makes it a single agency for businesses running both HubSpot and an Umbraco website. The mid-market and enterprise focus means it fits companies with real operational complexity rather than early-stage teams. A good fit for scaling B2B SaaS companies that need HubSpot RevOps, CRM enablement and systems integration handled by an experienced Elite partner.
