HubSpot CRM Rollout Across 6 European Offices for a Professional Services Firm

"Every previous CRM attempt failed because it was designed for a different kind of firm. Celumai understood that our relationship capital is in peoples heads and built a system that captures it without asking people to change how they work."

— Managing Partner, European Management Consulting Firm

The firm had attempted two CRM implementations in the past decade, both abandoned due to adoption failure. Partners resisted any system that added admin. The firm had no single view of client relationships, cross-selling was accidental, and attrition of senior partners took institutional knowledge with it.

We designed a HubSpot implementation built around the principle of minimum viable input — capturing relationship data through email integration, calendar sync, and LinkedIn rather than manual entry. We built a relationship strength scoring model and a cross-practice opportunity radar that surfaced potential cross-sells from existing client data.

Adoption reached 84% within 8 weeks, compared to under 20% in both previous implementations. £2.3M of previously invisible cross-practice pipeline was identified and assigned. Three cross-practice mandates closed within 90 days of go-live.

HubSpot challenges in Professional Services — what we see most often

Businesses in Professional Services running HubSpot often face the same underlying issues: data quality problems that compound over time, automation configurations that worked at launch but have not kept pace with the business, and adoption gaps that mean the CRM captures only a fraction of what it should.

The challenge is rarely the platform itself. HubSpot is capable of handling this complexity. The challenge is the implementation — the data model decisions, the integration architecture, and the process design that determine whether the platform works for the business or against it.

Celumai specialises in HubSpot implementations and rescues for Professional Services businesses. If the issues described in this case study are familiar, the causes and solutions are likely similar.
