Top 11 Lead Generation Companies For B2B and SaaS Companies 

B2B SaaS teams know how much work goes into filling a pipeline. You launch campaigns, test ideas, refine messaging, and try to stay visible in all the right places. 

Yet even with all that effort, there’s always that worry about whether enough qualified leads will show up or if it’ll be another stretch of slow replies and uncertain prospects.

Most of the time, the issue isn’t reach. Your audience sees you. They just aren’t ready to talk. SaaS buyers move at their own pace. They compare quietly,and only engage when something truly aligns with what they need. That silence makes lead generation feel unpredictable for even the strongest teams.

That’s where a good lead generation partner helps make the path easier. They understand intent, pick the right channels, and turn interest into real conversations.

In this article, we highlight agencies helping B2B SaaS brands build consistent, qualified pipelines.

Top 11 Lead Generation Agencies To Know In 2026

Choosing a lead generation partner is never easy. Every agency claims they can bring you qualified leads, but very few understand how SaaS buyers actually think or how long it takes to earn their attention. 

What you want is a team that knows your market, respects your buyer’s journey, and doesn’t force you into cookie-cutter campaigns.

So we put together a lineup of agencies that are known for doing meaningful work. These are the teams that understand intent and help B2B SaaS companies bring predictability back to their pipeline.

Here’s the lineup we’re diving into next:

1. Concurate
2. Belkins
3. CIENCE
4. Cleverly
5. Martal Group
6. Pearl Lemon Leads
7. SalesRoads
8. Callbox
9. Sopro
10. GrowthRhino
11. DemandWorks

Let’s explore how each of them helps in lead generation.

1. Concurate

Unlike traditional companies, Concurate sees lead generation as a different ballgame. You see, most companies treat lead generation like a numbers game. More outreach, more tools, and more pressure on prospects who never asked for it. 

At Concurate, we take a very different path. We believe the most valuable leads are the ones who discover you, trust you, and choose to walk toward you. That is why everything we do is built around inbound growth. When your marketing is strong and consistent, sales naturally follow.

At Concurate, the relationship usually begins with content. Not the usual content that fills space. We create content people look for when they are in the consideration and decision stage of their buying journey. The kind that makes someone pause and add your product to their shortlist. The kind that helps your audience understand your product better than they did before.

For instance, for one SaaS client, a single blog post outperformed paid ads and ranked #1 across the US, UK and Canada. Our team runs your content(based on the package you choose) and builds a regular publishing rhythm that earns attention without shouting for it. 

This includes LinkedIn, YouTube, and Email campaigns.  Our idea is to keep building your brand’s recall value so it appears as the top choice right when your prospects are ready to make the buy decision. 

In fact, it’s not even a numbers game. For one of our clients, we generated 24 leads from just three bottom-of-funnel blog posts.

Along with content, we add the right promotional layers to widen your reach. This includes LinkedIn ads, targeted distribution, and community engagement. When someone interacts with your brand, we do not let that moment vanish. We follow up with thoughtful messaging that feels like a continuation of your story, not a forced pitch. That is where our outbound touch comes in. It is always rooted in the trust your inbound engine has already created.

This combination of content, consistency, and human outreach is what makes Concurate different. You do not just get leads. You get people who come in informed and genuinely interested in your product. That is the kind of pipeline that compounds. 

Notable Clients

Concurate works with B2B and SaaS brands across domains like Fintech, Cybersecurity, Innovation management and IP Space. Notable names include Datacipher, Triangle IP, Inspire IP, PQAI, and more.

Pricing

Our pricing is custom and shaped around the scope of your inbound marketing and growth plans. For more details, you can contact our sales team.  

2. Belkins

Belkins is popular among B2B teams that need someone to take over the heavy lifting of outbound. Most SaaS companies already know their ideal customer profile, but don’t always have the internal bandwidth to run consistent outreach or keep follow-ups tight. That’s usually where Belkins fits in.

Source – Belkins

Their focus is simple: build a steady flow of meetings through structured outreach. They’re good at organizing lists, running sequences, and making sure prospects don’t slip through the cracks. For SaaS teams struggling with slow responses or long quiet stretches in their pipeline, Belkins can help bring some rhythm back.

They’re execution-focused and work best for companies that already know who they’re selling to and mainly need support with daily outbound activity.

Notable Clients

Belkins works with mid-market B2B companies across SaaS, IT services, manufacturing, and finance. Notable names include GE Healthcare, Sekisui, Mindstrong, and many more. 

Pricing

Belkins follows a custom-quote model. Pricing generally includes a monthly retainer for appointment setting or SDR support. Moreover, additional fees is charged for list building, deliverability, or consulting. They offer three core plans, along with an Enterprise tier for fully tailored outreach.

3. CIENCE

CIENCE is a US-based outbound services company that mostly supports teams that don’t want to manage outreach themselves. They handle tasks like building prospect lists, sending emails, making basic calls, and keeping campaigns running across a few channels, so internal teams don’t get stuck doing repetitive outreach work.

Source – CIENCE 

They also offer help with setting up the initial outbound system if a company hasn’t done it before. This includes sorting out the tools, data, and basic workflows. Their reps follow up on replies and try to keep conversations moving, but their approach is more operational than strategic. 

Most of what they do revolves around maintaining activity, organizing data, and keeping outreach consistent rather than shaping messaging or driving high-intent demand.

If your main issue is that outreach happens in bursts or stops whenever your team gets busy, CIENCE helps keep things moving steadily.

Notable Clients

Their notable clients include Microsoft, Google, Uber, Okta, and Yamaha, among others.

Pricing

Their pricing starts with a $5,000 GTM setup and moves into a monthly model that combines service fees with a $250 per-meeting charge.

4. Cleverly

Cleverly is mainly known for running LinkedIn-based outreach for companies that want more activity on the platform without managing it themselves. 

Most of what they do revolves around building prospect lists, writing short outreach messages, and sending them from your profile at scale. They also offer help with cold email and basic calling, but LinkedIn is their primary channel.

Source – Cleverly

Their team handles the day-to-day tasks that usually slows founders and sales teams down. It involves replying to initial responses, moving conversations forward, scheduling meetings, and keeping the inbox organized so nothing gets lost. 

Their entire model is built around volume-based outreach. They run multiple message sequences, test different variations, and tweak the campaigns based on which audiences respond better. 

It’s more of an execution service than a strategic partner, so companies typically use Cleverly when they want a steady stream of outreach happening in the background while they focus on closing the conversations that come in.

Notable Clients

Cleverly highlights clients like Full Pipe, Productiv, Yael Consulting, Adaptable, Blox, and Fuel to Fire.

Pricing

According to Cleverly’s website, their LinkedIn outreach plans range from $397 to $997 per month, depending on the level of outreach and appointment-setting support.

5. Martal Group

Martal Group is a North America–based outbound and sales support company that runs structured multi-channel prospecting for B2B teams. Their service revolves around building targeted prospect lists, sending cold emails, making basic calls, running LinkedIn outreach, and keeping early conversations organized so sales teams can take over when a lead is ready.

Source – Martal Group

They work through predefined tiers, from pure lead generation to helping with tasks like onboarding or early-stage follow-ups. 

Most of their model is process-driven, like weekly reports, message testing, clear outreach sequences, and consistent activity across channels. Instead of focusing on brand or demand creation, their role stays closer to managing the operational parts of outbound and keeping top-funnel movement steady.

Notable Clients

Martal Group has worked with companies like Deephow, HALO Recognition, Berger Levrault, Forerunner, and Afton Tickets.

Pricing

Martal offers tiered monthly plans, but for exact pricing, contact their team.

6. Pearl Lemon Leads

Pearl Lemon Leads is a UK-based lead generation company that focuses heavily on cold outreach across LinkedIn, email, and phone. Most of their offering sits around simple, volume-driven campaigns: building lists, writing short outreach messages, sending them from your profile, and handing over replies so your sales team can take it forward.

Source – Pearl Lemon Leads

They also run appointment-setting services, where their team schedules calls with people who match your target profile. Since they operate under the larger Pearl Lemon Group, they also offer optional add-ons like content help or broader digital marketing support, but their core service remains outreach and early-stage lead handling.

The company relies on message testing, basic personalization, and consistent activity across channels rather than deep strategy or demand creation. 

Notable Clients

Pearl Lemon Leads works with businesses like VMware, Twitter, the Olympics, Ascot, and the Princess of Germany.

Pricing

7. SalesRoads

SalesRoads positions itself as the team that handles the repetitive outreach and keeps your pipeline moving while you focus on nurturing and closing the deals that actually matter.

They handle the usual day-to-day tasks of sales teams like building prospect lists, reaching out on multiple channels, and keeping follow-ups consistent.

Source – Callbox

What makes their service workable for many companies is the combination of people and predictable processes. 

They already have teams who do research, write outreach messages, handle calls, and manage replies. Instead of reinventing the wheel each time, they plug your Ideal Customer Profile into their existing workflows and tools. 

For companies entering new regions or selling to markets they don’t fully understand, this structure helps them test outreach quickly without waiting months to hire and train internally.

Callbox also works across multiple geographies, so if a brand wants to expand into the US, APAC, LATAM, or Europe, they already have the data sources and the playbooks to build the first layer of pipeline there. 

Notable Clients

Callbox caters to clients of all sizes from medium sized companies to Fortune 500 companies. Popular names include AWS, HP, Acer. Zendesk, Intel and AMD.

Their work primarily involves researching relevant prospects, preparing outreach lists, and sending personalized messages on behalf of clients.

Source – Sopro

Their platform also gives basic visibility into campaign activity, reply tracking, and CRM handover. Most of their value comes from combining data, outreach workflows, and consistent message delivery, so clients don’t have to handle prospecting manually. 

Their service stays focused on starting conversations, not on providing broader sales strategy or consulting.

Notable Clients

Their clients include Fidelity Energy, Wooshii, Neighbourhood watch, and Coface. 

Pricing

10.GrowthRhino

Growth Rhino is a outbound-focused agency that mostly helps B2B teams get their cold outreach off the ground. 

They set up the basic plumbing like email domains, deliverability, prospect lists, and simple GTM workflows. Once that foundation is ready, they take over the day-to-day tasks of writing messages, sending outreach, and keeping conversations moving until someone from the sales team needs to step in.

Source – GrowthRhino

They describe their approach akin to running small experiments before scaling anything. Instead of blasting one message everywhere, they test different angles, tweak personas, and adjust sequences based on early replies. 

Because they handle list building, cold email, LinkedIn outreach, and basic appointment setting, teams mainly use them when they want a lightweight outbound engine without hiring extra people internally.

Notable Clients

Clients include Peekage, Comfi Payments, Educhain, Fincent, and Breadcrumbs.

Pricing

Their pricing starts at USD 12,000 per quarter, depending on the size of the engagement.

The Side-by-Side Breakdown You Need Before Choosing a Partner

Every agency in this list solves lead generation in a slightly different way. Some lean on outbound, some rely on data, and others mix channels to keep conversations moving. This section gives you a quick side-by-side view so you can see how they operate, what they focus on, and where their strengths sit.

You can use the table below to understand the differences at a glance and find the approach that fits your goals.

What to Look for in a Lead Generation Company

Picking a lead generation partner is a bit like picking someone to represent your brand in a room you’re not in. They’re the first conversation your future customers will ever have with you, so the bar has to be high.

Here’s what truly matters when choosing the right agency:

• They start with your ICP, not templates: A good partner understands who buys, why they buy, and what proof they need before saying yes.
  
• They respect the channels your audience trusts: Some buyers respond to email. Some move on LinkedIn. Others only engage after seeing repeated signals across content, ads, and search.
  
• They support both inbound and outbound motions:  Outbound teams need tight messaging and disciplined follow-ups. Inbound-led teams need content, search, and social to work together. The right agency strengthens the motion you already run, instead of forcing a new one.
  
• They focus on revenue, not noise: You should know which messages land, which leads matter, and where your pipeline is actually moving. Activity means nothing without impact.

When an agency gets all of this right, lead generation stops feeling unpredictable. It becomes a consistent engine you can trust.
And that’s exactly where Concurate’s approach stands out, by building demand before the first outreach ever happens.

Why Concurate’s Approach Wins Where Most Lead Gen Fails?

Most lead gen agencies chase buyers. However, at Concurate we believe that the best leads are the ones who discover you, trust you, and choose to take the next step on their own.

 That’s why our work starts with strong inbound. We create blogs that answer real user questions, LinkedIn content that makes people pause, YouTube videos that show expertise, and newsletters that keep your brand familiar without being salesy.

We don’t immediately blast prospects with messages. Rather we let your content do the heavy lift.  For some clients, we add light outreach only when someone has shown clear interest. It feels natural because it comes after genuine engagement. 

This approach brings you leads who already understand your value. They walk in warmer, and convert faster. 

If you want a lead pipeline built on trust and consistency, book a call with us and see how this framework can work for your SaaS brand.

Frequently Asked Questions

1. What does a lead generation agency actually do?

A lead generation agency helps you attract and engage potential buyers. Most focus on outbound work such as cold email, LinkedIn outreach, list building, and appointment setting. Some agencies also support inbound efforts by creating content, improving search visibility, or helping brands stay active on social platforms. Only a few agencies like Concurate takes a more holistic approach and combine both, building interest through strong inbound content and then converting that interest into qualified conversations. 

2. What’s the difference between inbound and outbound lead generation?

Outbound pushes messages to prospects who may not know you yet. Inbound attracts prospects through content, search, and social. Many companies use both, but the mix depends on how your buyers prefer to learn about new products.

3. Do lead generation agencies work for early-stage startups?

Yes. For early-stage startups, a good lead generation agency can be a major lift. It helps founders reach the right buyers faster, test messaging in the real world, and create early demand while the team focuses on building the product. Even if the ICP or positioning is still evolving, strong agencies can guide that refinement and help founders build the first predictable stream of sales conversations.
