B2B marketing isn’t easy. Unlike consumer marketing, you’re not selling to one person; you’re selling to committees, CFOs, and CEOs who need proof, not promises.
That means content, demand generation, paid ads, SDR outreach, and analytics all have to move in sync.
And building that kind of machine in-house? It’s slow, expensive, and often impossible for early-stage teams.
That’s why many SMBs turn towards marketing outsourcing companies for help. Instead of hiring full departments, you get specialized partners that offer on-demand expertise, predictable output, and faster execution without adding permanent headcount.
The challenge?
The market is crowded. Some firms deliver speed but little strategy. Others offer strategy but charge like enterprise consultancies. And only a few truly deliver the kind of A-player execution that drives consistent growth.
Below, we break down the top B2B marketing outsourcing companies in 2025 – what they’re best known for, and what you should consider before choosing one.
But first, let’s see what options you have to outsource B2B marketing.
Different B2B Marketing Outsourcing Models
There’s more than one way to bring in outside help. Here are the different models you have in 2025:
- Agencies – They handle everything from strategy to execution, but you’re looking at $10K–$25K a month in retainers. Best for companies with big budgets who want to stay hands-off.
- SDR/Outbound firms – These guys focus purely on filling the top of your funnel with cold outreach and lead gen. Great if you already have a solid marketing foundation and just need more pipeline.
- Offshore talent platforms – You get access to A-players at way lower costs because of where they’re based (that’s Pavago’s thing). Perfect for SMBs who want dedicated, high-quality marketers while reducing marketing costs.
- Enterprise consultancies – Lots of strategy, lots of money. Think big transformation projects and long-term roadmaps. These work for large organizations going through major shifts, not scrappy growth teams.
- AI-driven providers – They automate specific tasks like email sequences, reporting, or ad optimization to make things run smoothly. Best as a supplement to your team, not a replacement.
Now that you know how to differentiate between marketing outsourcing companies, let’s take a look at the best options available for B2B marketing:
Top 10 B2B Marketing Outsourcing Companies in 2025
1. Pavago – Best for SMBs that want A-players at fair prices
Pavago isn’t your typical marketing outsourcing company. Instead of outsourcing your marketing entirely, we help you hire dedicated offshore marketing talent that works directly for you, so they can scale without incurring bloated headcount costs.
Here’s how it works: instead of paying 30–35% recruiter fees or $10K+ agency retainers, Pavago uses a transparent model: $500/year membership + $329/month per hire. That means you can build your own full marketing team for less than what you’d pay a single agency.
Need a digital marketing manager, paid ads specialist, or marketing automation expert? You got it. You’re still spending less than one agency retainer, they’re working exclusively for you, and you own all the marketing material.
Every candidate comes from the top 1% of offshore professionals, vetted through technical interviews and ready to start in under three weeks. Payroll, contracts, and compliance are fully managed, and every hire is backed by a lifetime replacement guarantee.
For SMBs and startups that want enterprise-level marketers at a fraction of the U.S. costs, Pavago is the most cost-efficient and risk-free option.
2. MarketStar – Best for enterprise sales + channel enablement
MarketStar has decades of experience helping tech companies build SDR teams and partner programs. Their strength lies in large-scale sales outsourcing and channel enablement, making them best suited for mid-market and enterprise budgets.
3. EBQ – Best for “department-as-a-service” outsourcing
EBQ positions itself as a complete sales and marketing outsourcing company, capable of staffing full marketing teams. Based in the U.S., they offer strong control and deep expertise with platforms like HubSpot and Salesforce. However, this comes at a higher cost compared to offshore models.
4. Belkins – Best for appointment setting & outbound
Belkins focuses on outbound campaigns and SDR support, helping companies fill their sales calendars with qualified meetings. They provide transparent reporting, with booked calls as the core KPI. Belkins is ideal for companies that already have strong sales closers but lack top-of-funnel coverage.
5. DemandWorks Media – Best for demand generation at scale
DemandWorks Media specializes in large-scale demand generation campaigns, particularly content syndication. Their pay-per-lead pricing model makes them attractive for companies with significant budgets that need high-volume lead flow.
6. CIENCE – Best for data-driven outbound marketing
CIENCE combines outbound SDR campaigns with intent data, list building, and multi-channel outreach. They are especially strong at scaling prospecting quickly, making them a go-to choice for companies that want aggressive outbound activity powered by data.
7. SalesRoads – Best for U.S.-based SDR outsourcing
SalesRoads provides appointment setting with U.S.-only reps, which appeals to companies that prioritize cultural alignment with prospects. While the service comes at a higher price point, it’s a strong fit for complex B2B sales cycles.
8. SmartBug Media – Best for inbound + HubSpot marketing execution
SmartBug Media is a full-service inbound marketing agency and a HubSpot Diamond Partner. Their expertise lies in content marketing, SEO, and marketing automation, making them a strong option for companies that want to scale inbound pipelines using proven HubSpot-driven strategies.
9. Accenture Song – Best for enterprise-level digital transformation
Accenture Song focuses on large B2B enterprises looking for marketing and digital transformation at scale. They combine strategic consulting with execution across marketing and digital initiatives. Their services are expensive but unmatched in reach and capability.
10. Lyne.ai – Best for AI-powered outbound personalization
Lyne.ai is one of the modern marketing outsourcing companies that uses artificial intelligence to personalize cold email campaigns at scale, reducing the manual workload for SDR teams. It’s often used alongside human SDR outsourcing to improve efficiency and boost outbound performance.
How to Choose the Right B2B Marketing Partner
Before signing with any provider:
- Define your goal. Do you need output or ownership? Agencies execute everything, AI-driven providers provie you the tools, while offshore hiring lets you build and control your own team.
- Compare costs versus control. Agencies charge offer you pre-built teams but with no ownership or control. Pavago helps you hire people and you get direct access to your team.
- Check vetting standards. Your ROI depends on A-players, not juniors. Ask how rigorously candidates are vetted, and who will be working on your project.
- Evaluate risk. Look for lifetime replacements and full payroll management. You shouldn’t be scrambling if a hire doesn’t work out.
Why SMBs Are Moving Away from Outsourcing
Outsourcing sounds great… until you realize you’re renting talent, not owning it. You lose control, culture, and data visibility.
SMBs used to have two choices: hire locally and break the budget, or work with low-budget agencies and hope for results. Pavago has flipped the script. You can now build your own offshore team at a fraction of the cost, and actually own it.
You get the offshore price advantage, but the people are your team. They’re integrated into your workflows, trained to your standards, and fully invested in your success.

Frequently Asked Questions
Wrapping It Up
Marketing outsourcing companies come in many forms: agencies, SDR firms, consultancies, and offshore hiring platforms. Which one works best depends on your budget, your control needs, and your stage.
Most B2B marketing outsourcing companies rent you people for a project or campaign. Pavago works differently; it helps you hire them. You get access to the top 1% of offshore marketers who are ready to contribute from day one, but they’re a part of your team and you control them directly.
The economics are fundamentally better. You get the same performance and professionalism as big agencies, but without the markup and overhead.
If you’re an SMB or startup looking to scale from $2M to $10M in annual revenue strategically, building your own team offshore is worth exploring… and if you’re ready to do that, you know where to start.
