A HubSpot Diamond partner is a solutions partner that has reached the second-highest tier in HubSpot's Solutions Partner Program, above Gold and Platinum and below Elite. The tier is earned through the recurring revenue of the HubSpot accounts the agency manages and its client-success scores. It signals scale and experience, not a particular specialty or a quality guarantee.
A HubSpot Diamond partner is an agency or consultancy in HubSpot’s Solutions Partner Program that has reached the Diamond tier. The tiers in order are Partner (untiered), Gold, Platinum, Diamond and Elite, so Diamond is the second-highest level.
How an agency reaches Diamond
- Managing a large amount of recurring HubSpot revenue across its client accounts.
- Keeping a strong client-success score, which HubSpot calculates from how actively those clients use the platform.
- Maintaining the required certifications and program commitments.
HubSpot reviews tiers on a regular cycle, so Diamond status is held, not awarded once. Thresholds change over time, so check HubSpot’s partner directory for the current criteria.
What it means for a buyer
Diamond partners tend to be larger agencies with established HubSpot practices, dedicated HubSpot teams and experience with Professional and Enterprise accounts. That is useful if you are a bigger company with a complex setup. It is not a guarantee of fit. A Diamond agency focused on enterprise SaaS may be a poor match for a regional services firm, and a smaller Gold partner that knows your industry and your CMS may deliver more. Judge tier together with relevant work and the people who will actually run your account.
