CRM

CRM implementation and a foundation your team actually uses.

Not a CRM implementation as an IT project, but a data model that fits the way your team sells. We have been a HubSpot Platinum Partner since 2020 and are a monday.com Solution Partner. If you already run another CRM, we first look at whether you should leave it at all.

Our definition

What is a CRM foundation at Addmark

A CRM is not a software licence, it is the foundation your commercial engine runs on. Good CRM architecture starts with the data model, not with a vendor choice. Only when the objects, lifecycle and deal stages match the way your team sells does the tool come into the picture.

HubSpot has positioned itself since May 2026 as an agentic customer platform, no longer as a standalone Marketing Hub or Sales Hub. That aligns with how we approach CRM: a platform shared by marketing, sales and service, with a data model that reflects the sales cycle and not the other way around. If you want ongoing oversight of data hygiene and architecture drift, we often start with the CRM Scan to establish a baseline.

Five things a CRM foundation always has

  • A data model that fits your sales process, not a vendor template
  • Lifecycle stages and deal stages your team uses without explanation
  • A definition of MQL and SQL that marketing and sales agree on
  • Reports that do not get rewritten every quarter
  • An owner within your organisation who maintains the system

What a CRM foundation explicitly is not

  • A tool choice made before the data model
  • A Marketing Hub licence without a Sales and Service connection
  • 12 deal stages where nobody knows where a deal should sit
  • An implementation delivered by IT without a commercial review
  • A dashboard only the CRM administrator understands
Seven CRM services

Seven services that together form your CRM foundation.

CRM is the foundation on which marketing, sales and service run. Our CRM pillar covers the overarching implementation, the three HubSpot Hub implementations (Marketing, Sales, Service) and the architecture building blocks underneath. Available individually or as a bundle under a RevOps as a Service retainer.

Platinum Partner since 2020

HubSpot, for those who want marketing, sales and service in one platform

HubSpot has been an agentic customer platform since May 2026, no longer a standalone Marketing or Sales Hub. That fits how we build CRM, with a shared data model for the entire commercial engine. We have been a HubSpot Platinum Partner since 2020, that is 5+ years in the same stack, with certified consultants on Marketing, Sales, Service, Operations and CMS Hub.

Strong for: B2B mid-market, marketing-sales alignment, fast adoption, native connection between Marketing and Sales. Less suited for: highly complex enterprise models or strict custom-object requirements.

Solution Partner since 2026

monday CRM, for teams where a deal turns into client work.

monday CRM is built on a work platform. That is a drawback if you want a classic CRM and an advantage when selling and delivery run into each other: project-led service firms, agencies, and teams where a signed deal immediately becomes a project.

You create the relations between deals, contacts and accounts yourself, and that is where the risk sits: skip it and you are left with lists instead of a CRM. We design that data model and train the team on it.

Stay or switch

If you already run a CRM, the first question is whether you should leave it.

Often not. A system that does not run well is usually not a platform problem but a setup problem: a data model that does not match how you sell, stages nobody uses, reporting nobody trusts. We fix that inside what you have.

We do not build Salesforce ourselves; there we work with partners who do, often in a setup where Salesforce runs the sales side and we build the marketing and service layer.

If you do need to move, a migration is not a data export but a redesign moment. We redraw the data model, sharpen lifecycle stages and cut deal stages back to what your team actually uses. Only then does the data move, with pipeline history intact.

More about the migration process
Case · Saysimple

One customer view, numbers everyone trusts

Saysimple was running on Salesforce and wanted to move to HubSpot. The real question wasn't whether migration was possible, but how to do it without losing the existing pipeline history and without carrying over the old clutter.

We started with a week of strategy: the data model redrawn, lifecycle stages sharpened, and deal stages reduced from 12 to 7 with a scoring logic that fits their B2B cycle. Only then did the migration itself come into view.

Result: a cleaner HubSpot than they ever had in Salesforce, one hundred percent retention of pipeline history, and a forecast that's no longer rewritten three weeks later.

Frequently asked questions

Frequently asked questions about CRM engagements.

Questions we hear at every introductory call. Honest answers, no vendor talk.

Do you guide the CRM implementation including adoption and training?

Yes, for us those are one and the same engagement. A CRM that is technically set up but not used is wasted money, so adoption and training are fixed steps, not an optional extra billed afterwards. Carsten leads the setup and data architecture, Kim runs the adoption: hands-on sessions on your own pipeline, parallel support after go-live and an internal CRM owner who takes it over. Those who want to train more deeply can add CRM training. That way it runs from implementation to daily use without a gap.

When do you recommend HubSpot?

When marketing, sales and service need to sit in one platform with a shared data model. The UI is light enough for commercial teams to use without days of training, and the reporting layer is mature enough for a board pack. We have been Platinum Partner since 2020, so 5+ years in the same stack.

When is HubSpot not the right choice?

We encounter three situations. One, if a signed deal flows straight into client work, monday is often the better fit; that is what the platform was built for. Two, highly complex enterprise processes with deep custom objects and strict forecasting requirements, then we recommend Salesforce, and there we work with partners who build it. Three, organisations that only need a marketing tool without connecting sales or service, then HubSpot is too heavy and something lighter such as ActiveCampaign or Customer.io may suffice. Four, if your organisation already sits entirely inside the Microsoft stack and your commercial process is tied to ERP, Microsoft Dynamics 365 wins on that point; our HubSpot and Dynamics comparison explains exactly why.

How long does a CRM implementation typically take?

For a clean HubSpot implementation without migration, a mid-market engagement typically takes 6 to 10 weeks: 1 week strategy and data model, 2 to 3 weeks setup, 1 week integrations, 1 week testing and go-live, then 2 weeks of parallel support. A migration from Salesforce or Pipedrive typically adds 3 to 5 weeks, depending on data volume and number of integrations. We do not work with big-bang go-lives, always in phases with a go-live checklist and parallel support from Kim.

What do you do with our existing data?

The data strategy is a separate step before the migration itself. We map fields, identify duplicates, assess which history has value and which contamination is better left behind, and decide which objects migrate as 1-to-1 and which we redesign. Pipeline history can be retained in 100 per cent of cases, even when deal stages change, as long as we define the mapping upfront. At Saysimple we went from 12 to 7 deal stages without any loss of history.

Who builds the CRM on your side?

Carsten leads the architecture and data work, he is HubSpot certified on Marketing, Sales, Service and Operations Hub. Kim runs the adoption side, sales enablement and the parallel support after go-live. Carel joins as RevOps architect at kick-off and remains involved in the strategic decisions. For enterprise engagements with Salesforce we work with partners. For monday engagements Carsten and Kim build it together.

What if our sales team still does not use the CRM?

Adoption is half the work, which is why it is a separate step in the engagement, not something mentioned once after go-live. Kim runs the hands-on sessions on your own pipeline, not a demo environment, and is available daily in a chat channel plus weekly office hours for two weeks after go-live. After that we embed it in a retainer or close the engagement with an internal CRM owner who takes it over. If you want to invest more in adoption, take a look at CRM training.
