DOES THIS SOUND FAMILIAR?

HubSpot should work for your customer.
Not the other way around.

If any of these sound like a customer of yours, there's a SUM Digital service that fits — and a clean introduction is all it takes to get started.

 

SEE OUR SERVICES
1

Their marketing, sales and service teams aren't working in sync.

2

They need a system to scale go-to-market without scaling headcount.

3

They can't tell what's actually working and what isn't.

4

They don't have the time or know-how to get value out of HubSpot.

5

Their CRM is disorganised — sales-ready prospects fall through the cracks.

OUR HUBSPOT SERVICES

Seven services.
One clear path to value. 

Structured around the customer journey — so whichever stage your customer is at, there's a relevant next step that maps directly to a CSM-friendly outcome.

Phase 01
DIAGNOSE & DESIGN

Understand the portal, surface the gaps, design the path.

01
HubSpot Opportunity Scan

A 2-week diagnostic of the entire portal — technical health, commercial process, adoption — with a prioritised roadmap and ROI estimates. 

 

Total clarity in 2 weeks. A blueprint for what to fix, and why. 

02
Business Process Mapping

We translate how the business actually operates into a HubSpot-ready architecture. Data, automation, pipelines, governance — before anyone touches the build. 

 

A master blueprint. Zero guesswork in the build phase. 

03
AI Visibility Audit

Audit how the brand performs in AI-generated answers (ChatGPT, Claude, Perplexity). We deliver a concrete plan, executed inside HubSpot. 

 

Brand visibility where buyers are actually searching now. 

Phase 02
BUILD & LAUNCH

Implement, migrate, train. Own the outcome end-to-end.

04
Implementation & Migration

End-to-end portal build or migration against a co-created scope. Every property, pipeline and automation built to HubSpot best practice. 

 

A fully operational portal built to spec. No surprises. 

05
Guided Onboarding & Training

60–90 day objective-driven coaching where we guide the customer's team to build, own and operate their commercial infrastructure.

 

A team that genuinely owns what was built. 

07

Phase 02 + 03 · Ongoing

Consultancy

On-demand expertise to align the customer's HubSpot platform with their evolving business goals and complex operational requirements. Direct access to a senior HubSpot consultant for strategic sessions, technical execution, and continuous platform evolution. You get the peace of mind that your portal is always optimized for the next stage of your growth. 

Phase 03
SUSTAIN & GROW

Keep the portal alive. Compound the value over time.

06
HubSpot Support Desk

Ongoing ticket-based technical support for portal issues, broken functionalities and feature questions. Rapid resolution by HubSpot specialists. 

 

 No friction. No downtime. No churn triggers. 

HOW WE WORK WITH YOU

A clean, structured engagement

that reflects well on everyone. 

 

You're not handing your customer into a black box. We build visibility into the engagement so commitments stay honoured and the relationship stays yours.

1

Intro & discovery

You introduce us to the customer. We run a focused discovery call to confirm goals, constraints and the right service.

2

Co-created scope

A clear Project Scope: deliverables, timelines, ownership, milestones. Signed off before any work starts. No scope creep.

3

Execute & report

We build. We test. We share milestone updates with you and the customer — so you can speak to progress in every meeting.

4

Validate & hand over

Plenary offboarding, backlog decisions, training. The customer fully owns the result. The portal delivers value.

INDUSTRIES WE KNOW COLD

Deep expertise.
Not generalist

advice.

What others say about our HubSpot team

"Throughout the collaboration, it felt like they were an extension of our own team. The end result? A well-functioning HubSpot environment that supports our sales processes with clarity and ease. Thanks to smart setup and automation, we now benefit from increased operational efficiency and have unlocked new upselling opportunities through lead nurturing."

Anja Cappelle

Founder at Speakersbase

"They’re true experts who know exactly what they’re doing, with a structured yet flexible approach that fits our company’s core business and audience. What I appreciated most is how they think with you and always ready to optimize and get the absolute best for their customers.”

Houssem Latrech

Marketing Manager at Crowdled

"We had a great experience working with SUM Digital on our HubSpot implementation. They were always very clear on the scope of work, the objectives and the next steps to get there. On top of that, they really get things done quickly and surpass expectations!"

Francesco Redolfi

Co-Founder at OKR Mentors

The questions your customers always ask first.

Honest answers. Same ones we’d give them on a discovery call.

How do the implementation and onboarding work?

Our implementation and onboarding projects are structured around your business goals. We always start with a Discovery Call to understand what you want to achieve with HubSpot. Then, we kick off the project together with the Operations team, including the project scope, timelines and requirements.

We’ll schedule regular progress meetings where the action plan is reviewed, questions are answered and blockers are resolved. We’ll plan training sessions with your team separately, if they are part of the project scope.

Once the project is coming to an end, we’ll schedule a plenary offboarding meeting where we evaluate the project, discuss any backlog decisions and wrap everything up.

What investment can I expect upfront? I don’t want to be surprised.

The exact figures will depend on the scope and tech stack, but here are the typical investments we see: 


Onboarding & implementation (one-time): €1.5k–€6k for SMB, €3k-€12k for mid-market, depending on the number of Hubs.

 

Integrations (one-time): From €0–€1k for a marketplace app to €1k–€5k for middleware and €10k–€25k+for custom/API build (when data models and workflows are complex).

 

Process mapping/blueprint: €2k–€6k, depending on how many processes we map.

 

Enablement & training (yearly): €1k–€10k, depending on the number of sessions and teams.

 

HubSpot licenses (ongoing, billed by HubSpot): Pricing varies by Hub/tiers and contacts; we’ll outline options once we confirm scope.

Can I migrate the systems I’m currently using to HubSpot?

Absolutely, you can! Whether you use Pipedrive, Salesforce, MailChimp, ActiveCampaign or any other CRM, or if you use Excel for everything, we can migrate your legacy system to HubSpot.

How much time and effort will this take from my already overloaded team?

The actual time investment for a HubSpot implementation project depends on the complexity of the data and number of Hubs being implemented. Nevertheless, you should reserve at least 4-6 hours per week organization-wide to invest in this project.

We already have HubSpot, but no one uses it - can you help with that?

You’re at the right place! We offer various ways to make sure your team fully embraces HubSpot as their commercial platform, from trainings to an on-call support desk. We tailor our service to your needs to ensure the highest adoption rate.

Got a customer who could use our help?

A quick introduction is all it takes. Boudewijn handles discovery, scoping and delivery, and keeps you informed at every stage. Whether they need a full implementation, a diagnostic scan, or reliable ongoing support, there's a SUM Digital service that fits.

 Their GRR goes up. Their churn risk goes down. And you walk into every customer meeting with concrete progress to show.
