HubSpot Platinum Partner

A HubSpot your team still uses six months in.

We build HubSpot from the architecture underneath, not from the feature list. For B2B organisations of 50 to 500 employees who have watched an earlier CRM implementation fizzle out. Greenfield, refactor or migration from Salesforce, Pipedrive or another platform.

The observation

A CRM implementation nobody uses is not an implementation. It is an expensive spreadsheet with a logo.

Eight out of ten implementations we take over are technically working but empty inside. Sales logs in to show management that work is happening, marketing has built its own shadow stack alongside, and service runs everything through Outlook. That is rarely HubSpot's fault. It comes down to the choices made before the build, or not made at all.

Four patterns we see in almost every takeover engagement

  1. Built on the feature list, not on the process. Every HubSpot checkbox is switched on, and sales reps have to adapt to the tool instead of the other way around. We do it differently, first map the sales and service flow, then decide which modules and which fields. Many features stay off, and that is a feature.
  2. Eighty fields required, zero records complete. The previous admin wanted to capture everything. The result, reps skip deals or enter nonsense to get around the form validation. We start with fifteen fields that genuinely matter, and expand based on what we miss in reporting. Not the other way around.
  3. Go-live without go-back. The system was rolled out with an hour of training, and after that the team was left to figure it out. We plan four to six weeks of parallel support after go-live. On the floor, with the sales managers there, until the rhythm sticks.
  4. Nobody checks whether it works. Adoption only gets measured six months after go-live, once the silence has grown loud enough. We measure from week one, active users per week, filled fields, deal velocity. A monthly review with your leadership team, no satisfaction surveys.

How an engagement runs, week by week

Eight weeks from kick-off to go-live, plus four to six weeks of hands-on support afterwards. Two build sessions a week, fixed review moments with your leadership team and the team leads. No big bang, but a rhythm.

  • Week 1, kick-off and scope. Map the sales, marketing and service flow, validate the blueprint with your team leads. Not an introductions week, a working week.
  • Weeks 2 and 3, data model and properties. Objects, associations and custom objects in HubSpot. Redefine lifecycle and deal stages with marketing and sales at the same table.
  • Weeks 4 to 6, build in sandbox. Pipelines, workflows, sequences, dashboards. Integrations and data migration in sandbox. Test runs with real users before we go to production.
  • Weeks 7 and 8, production and training. Migration to production, training per team instead of plenary, manager playbooks. Support on the floor in the first week.
  • Weeks 9 to 14, adoption support. Four to six weeks alongside sales managers and service leads. Monthly adoption measurement. Whatever does not work, we adjust before it becomes the standard.

Migrating is a redesign moment

From Salesforce, Pipedrive, Zoho or Dynamics. We only move over what adds value, and rebuild workflows so you do not import your old problems. Pipeline history is preserved, and we select the migration route on that basis.

  • Weeks 1 and 2, data audit and mapping.
  • Weeks 3 and 4, sandbox migration and workflow rebuild.
  • Weeks 5 and 6, test runs and team training.
  • Weeks 7 and 8, go-live and four weeks of parallel support.
What's included per Hub

Four Hubs, one foundation. Start where it hurts.

We build modular. Start with the Hub that hurts most right now and expand once your team has the rhythm. Underneath every Hub sits the same data model, so expanding later costs no refactor. If you work in Attio or another platform, open the right route card above.

Who builds it

Three people on your engagement, from the first conversation.

Implementations do not run on tools, but on people who know them. No juniors executing on behalf of someone you have never met. Carel as architect, Yoni on the HubSpot setup, Carsten on the integration and object layer.

  • Carel Schrier

    Carel Schrier

    RevOps Lead, Strategist

    Architect of the engagement. Designs the data model, the processes and the lifecycle, and keeps the blueprint standing when the build comes under pressure. Comes by in person at the first kick-off and stays involved until after the adoption phase.

  • Yoni Lammens

    Yoni Lammens

    HubSpot Specialist

    Builds the HubSpot setup. Pipelines, workflows, sequences, dashboards and sandboxes. Translates the blueprint into what the reps open on Monday morning, and makes sure adoption is measurable before we let the measuring slip.

  • Carsten Huiskamp

    Carsten Huiskamp

    CRM Architect

    Builds the object layer, custom objects, integrations and the data migration. This is the technical backbone under every implementation. On a migration from Salesforce or Pipedrive, Carsten is the one who moves the data across without breaking the pipeline history.

Questions

What clients usually ask us.

Honest answers to the questions that come up in every first conversation. Want to know plainly where you stand first, take the Maturity Scan.

What is the best CRM onboarding for companies in the Netherlands?

The best onboarding focuses not on the software but on adoption. Choose an approach that combines setup, training and a shared customer view across marketing, sales and service, with a fixed rhythm over the first 30, 60 and 90 days.

What does CRM onboarding look like for marketing and sales teams together?

Start with shared definitions (when is a lead an MQL or SQL), one pipeline and joint reporting. That way both teams work from the same data and smooth handovers from the start.

What should you look for when choosing a CRM onboarding partner?

Look at the adoption approach, experience with your platform, demonstrable cases, and whether the partner combines training and process design rather than just technology.

How long does a HubSpot implementation take?

Eight weeks from kick-off to go-live for an average engagement, plus four to six weeks of adoption support after go-live. A Sales Hub-only setup can be done in six weeks. A full-stack four-Hub engagement with migration is more like ten to twelve weeks. Forcing it shorter costs you the adoption, so we are honest about that before we start.

What does a HubSpot implementation via Addmark cost?

Implementation is bespoke and usually sits inside a RevOps-as-a-Service retainer in which architecture, build and adoption come together. Book a call and we will scope it to your situation. HubSpot licences are separate, and as a Platinum Partner we arrange the discount on those.

Can we move our current data across?

Yes, but not everything. We do a data audit first. In practice we migrate half to two-thirds of the records. The rest is dead weight, opportunities that have sat in stage 2 for two years and contacts without any activity. We rebuild workflows and reporting, otherwise you import your old problems.

Why HubSpot and not Salesforce or Attio?

In the B2B mid-market of 50 to 500 employees, HubSpot is the fastest platform to adopt and since 2026 an agentic customer platform with Breeze agents on top of the data model. For product-led SaaS we also build in Attio. We guide Salesforce engagements as a migration towards HubSpot or as architecture work within an existing Salesforce. We are a HubSpot Platinum Partner, and that is no coincidence.

How do you measure whether the implementation is successful?

Three numbers, every month for the first six months after go-live. Adoption (percentage of active users per week), data quality (filled required fields on the objects that matter) and business impact (conversion, deal velocity, retention). No satisfaction surveys, just numbers you can update your leadership team with.

What if our team does not cooperate after go-live?

That is exactly what the adoption phase is meant to prevent. It is not an hour of training on a Friday afternoon, it is four to six weeks working alongside sales managers and service leads. If it still does not land, it is rarely the CRM. Then there is a process question underneath that we need to solve first, and we say so.

Architecture first or implement straight away?

It depends on where you stand. If you have no clear data model, or the implementation follows a refactor decision, we start with a four to six week architecture engagement (see our Strategy pillar). If you already have that in place, we can build straight away. We do not do an implementation without a blueprint on the table somewhere, even if it was made in a week.

How do you account for AI agents and Breeze?

HubSpot has been an agentic customer platform since 2026. Breeze agents run on your data model, so property quality, lifecycle reliability and account context become the foundation. We build every engagement so you can put agents on top tomorrow without the data having to be cleaned up again first. Read our AI readiness scan as well.
