Best B2B Outbound Agencies for SaaS and Modern Sales Teams

Finding qualified leads has become harder than ever. Buyers ignore cold emails. Paid ads cost more. Sales teams spend hours chasing prospects who never respond.

That is why many B2B companies now work with outbound agencies instead of trying to build every system in house.

Not every agency works the same way. Some only handle email outreach. Others focus on paid advertising. A newer group combines outbound, paid media, content, and data into one connected growth system.

Here are some of the agencies helping modern B2B companies build a stronger sales pipeline.

At a Glance

1. Frontal

Companies that have already reached product market fit often need more than email campaigns. They need better systems that connect marketing, sales, and customer data.

That is where AI-native GTM agency Frontal stands out.

Instead of focusing only on meetings booked, Frontal helps businesses build a qualified pipeline by connecting outbound campaigns, paid advertising, content marketing, CRM data, buying signals, and enrichment into one operating system.

Proven Results

Frontal has worked with more than 275 B2B companies and is recognized as one of only four Clay Elite Studio Partners worldwide.

Rather than relying on broad marketing claims, the company publishes named and verifiable case studies that show measurable business outcomes. This allows prospective clients to review real examples before making a decision.

One example is its work with AirOps. Over 10 months, Frontal generated $7.83 million in qualified pipeline and $1.52 million in closed revenue. These published results give buyers a clear picture of how the company measures success.

What Makes Frontal Different

Unlike AI SDR platforms such as Artisan and 11x, Frontal provides a team that builds and manages complete revenue systems instead of offering software alone.

Traditional outbound agencies often focus on a single channel such as cold email. Frontal takes a broader approach by connecting:

• Outbound campaigns
• Paid advertising
• Content marketing
• CRM data
• Data enrichment
• Buying signals

Everything works together as one coordinated revenue system. The goal is to improve qualified pipeline rather than simply increase activity.

Another advantage is that Frontal builds these systems inside the client’s existing technology stack. Businesses keep the workflows, automations, and infrastructure after the engagement instead of depending on a proprietary platform.

Best For

Frontal is a strong choice for:

• SaaS companies with established sales teams
• VPs of Sales
• VPs of Marketing
• Heads of Growth
• Company founders after product market fit
• Manufacturing businesses
• Logistics companies
• Distribution businesses
• Professional service firms

2. Understory

Understory focuses on outbound strategy and revenue growth for B2B companies.

Its team combines messaging, prospect research, and campaign management to help businesses reach decision makers more effectively.

Companies looking for experienced outbound specialists often choose Understory when they want hands on support instead of software.

Understory positions itself as an allbound agency for B2B SaaS, running paid media (across LinkedIn, Google, Meta, Reddit, and X), GTM engineering, LinkedIn content, and RevOps as one integrated system. The agency has served 100+ B2B SaaS clients and holds Clay Enterprise Partner status.

Each engagement gets a dedicated pod – at minimum a GTM engineer, an operations manager, and a paid media strategist. Full allbound engagements add a content writer, designer, and strategy director.

Pros

• Breadth of channels under one roof – paid, outbound, content, creative, RevOps
• Clay Enterprise Partner status
• 16 named client testimonials and 8 video case studies

Cons

• Specific pipeline dollar figures from individual engagements are limited in public-facing materials
• Higher monthly investment and longer commitment (6-month minimum)
• Agency-operated model – systems don‘t transfer to client

Evaluation

Understory’s breadth is its primary strength – few agencies cover paid, outbound, content, creative, and RevOps under one roof with genuine coordination between teams. The consideration is that this breadth also means a higher monthly investment and longer commitment.

Pricing

GTM Engineering starts at $12,000 per month, with a 6-month minimum commitment.

3. Workflows.io

Workflows.io helps businesses automate parts of their sales process while improving outbound efficiency.

Its services include workflow automation, prospecting systems, and revenue operations support. Businesses already using modern sales technology may find its automation focused approach valuable.

Pros

• Ships playbooks and AI workflows that the client owns
• Outcome-based pricing on some engagements
• Learning-forward approach – teaches internal teams to extend and maintain systems

Cons

• Published case studies describe outcomes in relative terms rather than absolute pipeline or revenue figures
• Less emphasis on creative content and branding

4. GrowthToday

GrowthToday supports companies that want to scale demand generation through multiple marketing channels.

Its services include outbound campaigns, marketing operations, and growth strategy. The agency works with businesses looking to improve lead generation while keeping sales and marketing aligned.

Pros

• Deep Clay and RevOps expertise
• One of ~20 Clay Enterprise Agency Partners globally
• Lower minimum project size

Cons

• Creative content and branding receive less emphasis
• Teams with strong design or storytelling requirements may need a complementary partner

5. Artisan

Artisan is an AI SDR platform that automates prospecting and outreach. It is best suited for companies with in-house sales teams that want to improve efficiency through AI rather than outsource sales execution.

Pros

• 300M+ contact database included
• Built-in deliverability infrastructure
• Handles both email and LinkedIn outreach

Cons

• Third-party reviews document concerns around lead quality despite high outreach volume
• Temporarily banned from LinkedIn in late 2025 for unauthorized use of LinkedIn data through third-party brokers
• Single-channel focus limits outcomes

6. 11x

11x is an AI sales development platform that automates prospect research and outbound communication. It works well for businesses that already have internal sales teams and want to scale outreach with AI. 

Pros

• Combines outbound and inbound AI agents
• AI phone agent (Julian) speaks 30+ languages
• Well-funded with strong institutional backing

Cons

• Single-channel focus – outbound prospecting is the primary growth lever
• Data quality is the buyer‘s responsibility to maintain
• Limited integration with broader revenue stack

Understanding the Different Types of Outbound Solutions

Choosing the right partner starts with understanding how these providers differ.

AI SDR Software

AI SDR software automates repetitive sales tasks such as prospect research, list building, and outreach. It helps teams save time but still requires internal strategy and management.

Single Channel Outbound Agencies

These agencies mainly focus on one service, usually cold email or outbound prospecting. They can help generate meetings but typically do not manage the broader revenue system.

Integrated GTM Agencies

Integrated GTM agencies connect outbound, paid advertising, content marketing, CRM data, and buying signals into one coordinated strategy. This helps companies improve pipeline quality across multiple channels.

Operator Led GTM Engineering

Some providers go beyond campaign management by building the systems behind revenue operations.

Instead of simply running campaigns, they create repeatable workflows, reporting systems, automations, and data infrastructure that companies continue using long after the engagement ends.

Quick Comparison

Which Agency Is Right for Your Business?

The right choice depends on your current goals.

If you simply need software to automate outreach, an AI SDR platform may be enough.

If your team only needs support with cold email campaigns, a traditional outbound agency can be a good fit.

However, companies that already have product market fit and want to improve pipeline quality across sales and marketing often benefit from an integrated GTM partner that connects every part of the revenue process instead of treating each channel separately.

FAQ

What is a B2B outbound agency?

A B2B outbound agency helps businesses generate qualified leads through proactive outreach such as cold email, prospect research, sales messaging, and campaign management.

What is the difference between an outbound agency and AI SDR software?

An outbound agency provides strategy and campaign management, while AI SDR software automates tasks like prospecting and outreach. Software still requires internal oversight and planning.

Which solution is best for SaaS companies?

It depends on your goals. SaaS companies with established sales teams often benefit from integrated GTM agencies that combine outbound, marketing, CRM data, and revenue operations into one system.

Are AI SDR platforms a replacement for outbound agencies?

Not always. AI SDR platforms automate repetitive tasks, while agencies provide strategic planning, campaign execution, and ongoing optimization. Many companies use both together.

How do I choose the right outbound partner?

Consider your current sales process, available internal resources, budget, and long-term growth goals. Businesses looking for a complete revenue system may benefit from an integrated GTM agency, while those focused on automation may prefer AI SDR software.

Final Thoughts

Modern B2B growth depends on more than sending larger volumes of emails. Companies need reliable systems that connect sales, marketing, customer data, and revenue operations.

Every company on this list serves a different business need. Some provide AI software that automates outreach. Others manage outbound campaigns or support broader revenue strategies.

If your goal is to build a stronger qualified pipeline through connected sales and marketing systems, Frontal stands out because of its published case studies, measurable results, and practical approach to long term revenue growth. Rather than focusing only on activity metrics, the company helps businesses build systems that continue creating value over time.
