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. In 9 out of 10 engagements we choose HubSpot, for modern B2B SaaS also Attio, for enterprise situations Salesforce. We have been a HubSpot Platinum Partner since 2020, so 5+ years in the same stack.

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 Maturity 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.

By platform

Which CRM fits your situation

In 9 out of 10 engagements we choose HubSpot because it offers the best balance between power and adoption in the B2B mid-market. For modern B2B SaaS teams we also work with Attio, for enterprise situations with Salesforce. And sometimes a migration from one to the other is the right answer. Click a platform for the details.

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.

Modern B2B SaaS

Attio, for B2B SaaS teams that want speed and flexibility

Attio is a more modern CRM that excels at flexible data models and API-first working. For young B2B SaaS teams combining a product-led motion with outbound, who find the UI of Salesforce or HubSpot too heavy, this is often a better fit.

Strong for: fast setup, clean UI, API-first integrations, product-led SaaS context. Less suited for: large marketing teams who want everything in one tool or organisations with strict enterprise reporting requirements.

More about CRM architecture

Enterprise

Salesforce, for enterprise situations with complex processes

Salesforce is strong in enterprise contexts, complex sales processes and extensive custom object models. We do not build Salesforce ourselves, but we work with partners who do. Often in a hybrid scenario where Salesforce runs the sales side and HubSpot handles the marketing and service layer.

Strong for: enterprise models, complex forecasting, broad custom objects. Less suited for: mid-market B2B with limited CRM capacity or teams that need to move fast.

More about integration strategy

Migration

Migration to HubSpot or Attio without losing pipeline history

Migration is not a data export. It is a redesign moment. We start with a week of strategy: redrawing the data model, refining lifecycle stages, reducing deal stages to what your team actually uses. Only then does the migration itself come into view, preserving pipeline history and leaving old clutter behind.

Typical sources: Salesforce, Pipedrive, Zoho, Microsoft Dynamics, Copper and standalone legacy databases. Target: HubSpot in 90 per cent of cases, Attio for modern SaaS teams.

Case, Saysimple · Saysimple

Van losse tools naar een pipeline die de directie vertrouwt

From Salesforce to HubSpot, with a redesigned data model.

Saysimple was running on Salesforce and wanted to move to HubSpot. The question was not whether we could migrate, any partner with HubSpot knowledge can do that. The real question was: how do you do it without losing the existing pipeline history and without carrying over old clutter.

We started with a week of strategy. Data model redrawn, lifecycle stages refined, deal stages reduced from 12 to 7 and a new scoring logic that works for their B2B cycles. Only then did the migration itself come into view. The result is a cleaner HubSpot than they ever had in Salesforce and a forecast that no longer gets 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.

Why do you choose HubSpot so often?

Because HubSpot offers the best balance between power and adoption in the B2B mid-market. Marketing, sales and service sit in one platform with a shared data model, the UI is light enough to be used by commercial teams without days of training, and the reporting layer is mature enough for a board pack. We have been Platinum Partner since 2020, that is 5+ years in the same stack. In 9 out of 10 engagements we land on HubSpot. For modern B2B SaaS sometimes Attio, for enterprise situations Salesforce.

When is HubSpot not the right choice?

We encounter three situations. One, highly complex enterprise processes with deep custom objects and strict forecasting requirements, then we recommend Salesforce in a hybrid scenario. Two, product-led B2B SaaS teams that value speed and API-first working over a broad marketing platform, then Attio is a better fit. Three, organisations that only need a marketing tool without connecting sales or service to it, then HubSpot is too heavy and a lighter tool such as ActiveCampaign or Customer.io may suffice. In the other 9 out of 10 cases HubSpot remains the best choice.

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 Attio 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.
