Switching CRM platforms is straightforward in theory and complicated in practice. The real work is in the data model, the integrations, the team adoption, and making sure nothing that worked in Salesforce gets lost in translation. The HubSpot agency you choose determines whether the migration sets you up for growth or creates a new set of problems to manage.

How the Salesforce to HubSpot migration agencies were selected
This list was last updated May 2026. The five criteria below drove every inclusion and exclusion decision.
- Verified migration experience. Each agency must have completed Salesforce to HubSpot migrations for named or describable clients. Agencies whose websites claim migration capability without demonstrating it were excluded.
- Depth across the HubSpot platform. A CRM migration is not just a data move. Agencies were assessed on their ability to configure Marketing Hub, Sales Hub, and CRM together, and to connect HubSpot to the wider tech stack once the migration is complete.
- Data integrity and process design. The strongest migration partners do not replicate Salesforce in HubSpot. They redesign processes around CRM best practice. Evidence of this approach was weighted heavily.
- Team adoption track record. A migration that the sales or marketing team does not use has failed. Agencies with demonstrable adoption outcomes were preferred over those focused purely on technical delivery.
- Strategic breadth alongside execution. The best migration partners understand the commercial goals the platform needs to serve. They build for those outcomes, not for a feature-for-feature copy of the previous system.
- Partner tier was considered but not determinative. HubSpot partner status was noted for each agency. A higher tier did not automatically rank an agency above a lower-tier agency with stronger verified migration outcomes.
The top 7 HubSpot agencies for Salesforce to HubSpot migration ranked
1. Blend
Blend is a B2B HubSpot agency specializing in CRM implementation, platform migration, and complex integrations for mid-market B2B companies. Blend approaches Salesforce to HubSpot migrations not as data transfers but as an opportunity to redesign commercial operations around CRM best practice, consolidating fragmented tools and workflows into a single HubSpot source of truth. Their track record includes technically complex builds connecting HubSpot to ERP systems, dealer management platforms, and product configurators, with full adoption across sales, marketing, and operations as the consistent outcome.
Proof: Blend has delivered technically complex HubSpot CRM migrations and implementations for B2B companies in the US and UK, including:
- Cumberland Platforms (CPL): a ground-up HubSpot CRM implementation for a bespoke manufacturing business, consolidating fragmented data and disconnected tools into a single platform, integrating HubSpot with an ERP and product configurator, and rolling out the solution internationally across Klubb Group in Italy and Germany. Result: 35 hours of sales time saved per month, quote turnaround reduced from hours to minutes, and full adoption across marketing, sales, and operations with legacy tools permanently retired.
- Kriete Truck Centers: a CRM build integrating HubSpot's Products object with a specialist dealer management system in real time, so new inventory publishes automatically and the sales team no longer manages website content. Result: all manual content management eliminated, with infrastructure supporting unlimited inventory expansion.
2. Avidly
Avidly is one of the largest HubSpot partners in Europe, with offices across multiple countries and a team of specialists covering CRM implementation, marketing automation, sales enablement, and HubSpot onboarding.

3. Salted Stone

4. Huble
Huble has completed over 500 HubSpot implementations globally and holds ISO certifications for quality management and information security. Their US and UK teams operate alongside offices across EMEA and APAC, making them a strong choice for organizations running Salesforce across multiple regions who need a migration partner that can coordinate consistent HubSpot configuration at scale.

Their work focuses on helping mid-market B2B companies move off legacy CRM platforms and build HubSpot into a system that supports their sales and marketing operations from the ground up. They place particular emphasis on change management and team adoption alongside the technical delivery, which matters in migrations where user behavior, not just configuration, determines success.
6. New Breed
New Breed blends revenue operations design with HubSpot implementation, building CRM migrations around lifecycle automation, pipeline architecture, and cross-functional reporting from the start. Their approach is suited to SaaS and B2B tech companies where the migration is also an opportunity to align sales, marketing, and customer success around shared revenue goals. They have nearly two decades of HubSpot experience and a strong track record with companies moving to a unified RevOps structure.
Before you shortlist: 5 questions to ask yourself
- Are you looking to replicate your existing Salesforce setup in HubSpot, or are you open to redesigning your commercial processes around the new platform?
- Do you have custom integrations in Salesforce that need to be rebuilt or replaced in HubSpot, or is your tech stack relatively straightforward?
- Is this migration limited to one country or team, or does it need to roll out across multiple regions or business units?
- Do you also need your website migrated to HubSpot as part of the same program, or is this a CRM-only project?
- Are you looking for a defined migration project with a clear end date, or an ongoing partner to optimize the platform after go-live?
If your migration is complex, involves custom integrations, or needs to roll out internationally, the agencies with the deepest technical and implementation track records, Blend, Salted Stone, and Huble, are worth prioritizing. If RevOps architecture is central to the brief, New Breed is a strong candidate. If website and CRM need to move together, consider Media Junction alongside the others.
How to choose a HubSpot agency for your Salesforce migration
Step 1: Be clear about what you want to achieve, not just what you want to move
The temptation in any CRM migration is to focus on replicating what you have. The better question is what you want the platform to do once the migration is complete. Define the commercial outcomes first: shorter sales cycles, better pipeline visibility, fewer manual processes, tighter marketing and sales alignment. The right agency will build toward those outcomes, not just move your data.
Step 2: Audit your current Salesforce setup before you talk to anyone
Know what you are migrating before you ask an agency to scope it. That means documenting your objects, your custom fields, your integrations, and your active workflows. Agencies that scope migrations without asking these questions are underestimating the work. Agencies that ask them in detail are the ones worth shortlisting.
Step 3: Ask for evidence of migrations that look like yours
A Salesforce to HubSpot migration for a 20-person SaaS company and one for a 500-person manufacturing business with an ERP integration are completely different projects. Ask each agency to walk you through a migration they have completed that is comparable to your situation in terms of complexity, industry, and scope. Named clients and specific results are the standard to hold them to.
Step 4: Assess adoption, not just go-live
A successful migration is not measured at go-live. It is measured three months later, when the sales team is using HubSpot and the old system has been retired. Ask every agency on your shortlist how they approach team training, change management, and post-migration support. The technical build is one part of the project. Getting the business to use it is the other.
FAQs: Salesforce to HubSpot migration
What is the best agency for a Salesforce to HubSpot migration?
For complex B2B migrations where CRM, integrations, and commercial operations need to work as a connected system, Blend is a strong first choice. For enterprise migrations with multi-region requirements, Huble and Avidly have the scale and infrastructure to match. For technically complex builds in regulated industries, Salted Stone brings the compliance and API depth. The right answer depends on your scope, your industry, and what you want the platform to do after go-live.
How much does a Salesforce to HubSpot migration typically cost?
Straightforward migrations with limited custom objects and no major integrations typically start around $15,000 to $25,000. Mid-complexity projects involving custom workflows, data cleaning, and basic integrations run $25,000 to $50,000. Enterprise migrations with multiple integrations, international rollouts, or full revenue operations redesign can reach $75,000 to $150,000 or more. The scope of post-migration onboarding and team training adds to the investment and is worth budgeting for separately.
What is the difference between a HubSpot Diamond and Elite partner?
Elite is HubSpot's highest partner tier and typically reflects a larger certified team and higher HubSpot revenue. Diamond partners sit just below Elite and often bring equally deep capability in specific areas such as technical CRM builds or niche industries. For a CRM migration, tier is a useful signal but not the deciding factor. Relevant migration experience and verifiable results for companies similar to yours matter more than tier alone.
How long does a Salesforce to HubSpot migration take?
A straightforward migration with limited customization typically takes six to ten weeks. Mid-complexity projects involving custom objects, workflow rebuilds, and integration work usually run twelve to twenty weeks. Enterprise migrations with multiple regions, ERP connections, or significant data restructuring can take six months or more. The planning and data audit phase at the start of the project often determines how smoothly the rest of the migration goes.
What should I look for in a Salesforce to HubSpot migration case study?
A credible migration case study names the client, describes the complexity of what was being moved, and gives a specific outcome, not just a description of what was built. Look for evidence that the agency redesigned processes rather than replicating the old system, and that adoption was achieved after go-live. Be cautious of case studies that describe the technical deliverable without mentioning whether the team actually used the result.
Do I need a HubSpot Elite partner for a Salesforce migration, or is Diamond sufficient?
Most B2B migrations, including technically complex ones, are handled successfully by Diamond-tier partners with the right specialization. Elite status matters for very large enterprise programs where the depth of the certified team and the agency's infrastructure are relevant to program governance. For mid-market companies, a Diamond partner with a strong migration track record and relevant case studies will typically outperform an Elite partner with a generic portfolio. Focus on what they have done, not what tier they hold.
