8 HubSpot Agencies for B2B Teams Using Salesforce
HubSpot closed 2025 with 288,706 paying customers—nearly double Salesforce’s reported 150,000-plus—and a growing share of those companies run both platforms at once. Marketing and RevOps live in HubSpot; the sales team’s system of record stays in Salesforce. That split is powerful, but it is also where deals quietly leak. Studies of B2B process friction consistently find 5–15% revenue loss at manual handoff points, and a poorly architected HubSpot–Salesforce sync is one of the most expensive handoffs a growth team can own.
The right agency does more than “install the connector.” It designs a bi-directional data model, maps lifecycle stages to Salesforce opportunity stages, prevents duplicate records, and makes paid media and demand generation accountable to pipeline that closes in Salesforce. Below are eight agencies worth a conversation if you run HubSpot on top of Salesforce—chosen for demonstrated RevOps depth, integration experience, and B2B focus.
What actually matters when your CRM is Salesforce
Before the list, three criteria separate a capable partner from a risky one. First, integration architecture: can they handle custom objects, non-standard lifecycle stages, and complex deal-stage mapping rather than relying on the default field sync? Second, RevOps fluency: HubSpot itself reports that 57% of users credit it with aligning marketing and sales, but that alignment only materializes when reporting reconciles across both systems. Third, demand and paid media that ties to closed revenue—not lead volume that stalls before it reaches a Salesforce opportunity. Every agency below was evaluated against those three lenses.
The 8 agencies
1. VSSL Agency
VSSL is a B2B tech marketing agency built for teams that need paid media, marketing operations, and HubSpot expertise to work as one system. For companies where HubSpot drives marketing and Salesforce holds the revenue record, VSSL’s strength is connecting campaign spend to pipeline—architecting the sync, aligning lifecycle stages, and building reporting that both marketing and sales leadership trust. Best for growth-stage and mid-market B2B teams that want measurable pipeline, not vanity metrics.
2. SmartBug Media
SmartBug is HubSpot’s most-decorated Elite Solutions Partner and its 2025 North American Partner of the Year, holding every advanced HubSpot accreditation and more than a thousand certifications. Its capabilities span full-funnel demand generation, RevOps, CRM architecture, and complex HubSpot-centric integrations—making it a strong fit for mid-market and enterprise SaaS running HubSpot alongside Salesforce. Best for larger teams that want breadth and deep accreditation under one roof.
3. New Breed
A long-standing HubSpot Elite partner, New Breed pairs account-based marketing with demand generation for SaaS companies typically at $5M+ ARR. Its RevOps practice is well-suited to organizations that need HubSpot marketing data to reconcile cleanly with a Salesforce pipeline.

4. Walker Sands
Walker Sands is an integrated B2B agency for technology companies with complex offerings, combining PR and demand generation to build authority and pipeline at once.

Best for organizations with long sales cycles that need marketing tightly coupled to a Salesforce-based sales motion.
6. Penguin Strategies
Penguin Strategies is a HubSpot Elite Partner specializing in revenue operations across complex sales cycles and multi-system environments—exactly the profile of a company running HubSpot and Salesforce in parallel. Its focus on global SaaS and manufacturing teams makes it a fit where data lives in more than one platform. Best for teams whose primary pain is systems integration and RevOps, not just campaigns.
7. WebMechanix
WebMechanix is a performance-driven agency built around conversion rate optimization and paid media, using a structured methodology to improve each stage of the funnel. For HubSpot-on-Salesforce teams, its value is making paid acquisition accountable to downstream pipeline rather than top-of-funnel leads alone. Best for teams whose priority is squeezing more qualified pipeline out of existing paid spend.
8. Set2Close
One of HubSpot’s fastest-growing Elite Partners, Set2Close concentrates on HubSpot CRM and RevOps to accelerate B2B sales. Its operations-first orientation suits companies that need clean process and reporting between HubSpot and Salesforce before layering on more demand. Best for teams that want to fix the revenue engine’s plumbing first.
How to choose the right partner
Tier matters less than fit. Elite is HubSpot’s highest partner level and usually signals more certified headcount and platform breadth, but for many B2B teams a partner with a verifiable SaaS portfolio and real Salesforce integration scars will outperform a bigger firm with a generic client base. Ask any shortlisted agency to walk you through a HubSpot–Salesforce sync they architected: how they handled custom objects, lifecycle-to-opportunity mapping, deduplication, and cross-system reporting. The answers will tell you quickly whether they’ve done the hard part or only the easy one.
It’s also worth weighing where the market is heading. Both HubSpot and Salesforce are reshaping their partner programs for the AI era, which means the agencies that keep pace on automation and data hygiene will compound advantages for their clients. Pick a partner that treats your integration as living architecture, not a one-time setup.
