1. Salesbread – Best for LinkedIn lead generation

LinkedIn graph showing which industries were the hardest to get a reply from

SalesBread is a B2B LinkedIn outreach agency that specializes in bringing clients 1 qualified sales lead per day. Since 2019, SalesBread clients have averaged a 19.98% reply rate with our ultra-personalized LinkedIn lead generation services.

And…

48.14% of those replies were either meeting requests or qualified sales inquiries on their product or service.

Wondering how we achieve this?

Here’s our secret:

  • Obsessive list building

  • Ultra-personalized LinkedIn outreach (No sleazy sales copy)

  • Following up consistently

  • Asking for a booked call

At Salesbread, we don’t just stop at basic list building but look for patterns between your current buyers, and this helps us build look-a-like lists of prospects to go after.

We do this to understand and find your IDEAL target prospects.

We analyze your current customers through 34 business attributes and “signals.” This helps us find customers who need what you’re selling and have the buying power and budget.

The video below shows an example of how we would do this:

Our list-building process normally takes a week to perfect.

Once it’s perfect and we have found the right people to reach out to at these accounts, we will then research each prospect on the list and send them a personalized outreach message.

We do this manually and don’t use any AI for writing our messages.

In fact, we have a full-time personalization expert whose sole job is to research prospects and find something very specific to mention in our messages.

(E.g., “By the way, I listened to your interview on the cold outreach podcast and appreciated your insights on why today’s quota-driven sales teams need to focus on quality, not quantity.”)

We actually look for something to either compliment the prospect on, mention a commonality, or ask them a question.

(You can read more about our CCQ method here.)

This captures the attention of our prospects and sets our messages apart from every other salesperson on the platform.

Next, we will follow up consistently with our prospects and ask for a booked sales call.

Pros

  • Obsessive list building

  • Ultra personalized outreach

  • Multichannel approach (LinkedIn, Cold email, and SMS)

  • 1 Qualified sales lead per day

  • You work with the founder of the b2b demand gen agency, Jack Reamer. You won’t be fobbed off on a junior salesperson.

  • We will teach you our demand generation strategy so that once our partnership has ended, you can take the process in-house.

  • There are no locked-in contracts.

  • Have generated leads for a number of industries – HR, Fintech, Reg Tech, HR, Health & Wellness, Law Firms, education, SaaS, and even video production.

Cons

Best for:

SalesBread is a good choice for companies that want to use LinkedIn to generate leads. They are also a good choice for those who want one lead per day.

SalesBread is a great fit for founders and small to mid-size sales teams.

Pricing

Unlike inbound and content marketing, our b2b demand generation campaigns produce results fast. You can expect your first lead within 48 hours of launching the campaign.

Even within month one, we will still be hitting the 1 lead a day benchmark that we set for ourselves.

Our service essentially replaces the need for a trained Outbound Sales Rep at your company — for less than half the cost of a full-time salary.

Reviews

Salesbread receives a 5-star rating based on 54 reviews on LinkedIn.

I have had huge struggles figuring out how to market my virtual CFO services business, use lead generation, and reaching out to my dream clients. Most other so called marketing experts I have spoken to have scared me in more ways than I can count!

Oh it is just a matter of running a bunch of ads (and blowing my hard earned dollars), running a funnel, & making myself dependent on someone to “fish for me to bring the fish back to my kitchen” instead of me learning how to fish myself so that I am confident in my ability to market my businesses valuable offerings.

Not so with Jack! Jack clearly put me at ease, helped me trust his expertise and clearly showed me he has credibility with the B2B market in applying his knowledge.

On our first call, he was clearly excited in helping me achieve my goal of being self sufficient with my marketing skills compared to others that just wanted me to be dependent and spend huge amounts of money I didn’t have. We then got on another call and the value I got from the 2nd call was absolutely enormous and left me with way more mental clarity than I have ever had before.

I feel a lot more confident thanks to Jack. Trust me, you will be thankful you got on a call with him!

Growth Hackers review

5. Grow & Convert – Best for content marketing and SEO

Grow and Convert logo

Grow & Convert was founded by Benji Hyam and Devesh Khanal, and from the start, they’ve had a pretty clear point of view: most content marketing is a waste of time.

Instead of chasing high-volume keywords that attract curious readers who never buy anything, they focus on intent-based keywords, the searches people make when they’re already looking for a solution like yours.

What also sets them apart is how they write. Most agencies hand a topic to a writer and tell them to Google it.

Grow & Convert actually interviews your founders and team members to garner real expertise, genuine insights, and the kind of nuance that makes content convincing.

Pros

  • Targets high-intent keywords, so the traffic you get is far more likely to convert

  • Content is built from real interviews with your team, not recycled research

  • Paid ads and link-building are part of the mix, not just blog posts

  • They track and report on actual conversions, not just traffic vanity metrics

Cons

  • This level of quality comes at a price — it’s not a budget option

Best for

Grow & Convert is best for established B2B or SaaS companies that have already figured out their product-market fit and are ready to invest seriously in content as a growth channel.

If you’re at a stage where you need a steady source of high-quality inbound leads and not just traffic, they’re one of the best options out there.

That said, at $9–10k a month, they’re not for everyone.

If you’re early-stage, bootstrapped, or still testing whether content is the right channel for you, the investment is hard to justify. But if you’re ready to go all-in and want an agency that actually ties its work back to revenue, Grow & Convert is worth a serious conversation.

Pricing

Their standard rate is $10,000/month, though they’re currently onboarding new clients at $9,000/month for the first year.

This is still a big investment, but a decent entry point if you’re serious about content-driven growth.

Reviews

Grow & Convert holds a 4.8 out of 5 rating on Clutch, which is about as strong as it gets for an agency at this level.

6. The ABM Agency – Best for PPC 

The ABM Agency logo

The ABM Agency specializes in account-based marketing (ABM). They help companies find targeted clients and help businesses target clients with personalized and strategic campaigns.

They have a team of account-based marketing and demand generation specialists who leverage SEO, PPC, content marketing, programmatic marketing automation, and analytics.

Furthermore, they focus on delivering content and messaging that resonates with decision-makers at targeted companies.

Pros

  • They have a multi-channel focus for finding high-quality leads – SEO, PPC, and content marketing

  • They have worked with high-profile clients, such as Siemens and IBM

Cons

  • Based on research across the web, the ABM Agency seems to be quite expensive.

Best for

The ABM Agency is best for mid-sized to enterprise B2B companies with a clearly defined target market and a longer, more complex sales cycle.

They’re probably not the right call if you’re early-stage and still figuring out your ideal customer, or if you need fast, high-volume lead generation.

Pricing

Unfortunately, they don’t mention pricing on their website. You would have to contact them directly, but from some research, they seem to be quite costly.

Reviews

According to Clutch, The ABM Agency has a 4.5-star rating out of 5.

The ABM Agency review

7. Belkins – Best for cold calling

Belkins logo

Belkins is a B2B lead generation agency specializing in several outbound methods, including cold calling.

Belkins’ cold calling approach focuses on building rapport and nurturing leads rather than using pushy tactics, which leads to higher conversion rates and better client relationships.

They do this by building a list of qualified leads and contacting them via different channels before they actually call them.

Their SDR team prequalifies leads, prioritizing those who showed positive signals (including those who previously asked to connect later or stopped responding after initial engagement).

They will gather information on each lead, examining pain points, ICP, and your product fit to connect organically when following up via cold calls.

Pros

  • Expertise in intent-based cold calling

  • They provide detailed reporting on the progress of your campaigns

  • They offer a variety of outbound lead generation services

  • Belkins is an international agency

Best for

They’re a good fit whether you’re a startup trying to get your first meetings booked or a larger business that simply doesn’t want the headache of managing an in-house SDR team.

If you want a more boutique, high-touch agency experience, though, they might not be the right fit.

Pricing

Unfortunately, Belkins doesn’t mention exact pricing on their website. You would have to reach out to them directly for a quote.

According to Clutch, their minimum project size is $1,000+, and their average hourly rate is < $25 / hr.

Reviews

Belkins has good ratings across various websites. According to G2 they have a 4.8 star rating out of 5.

Reviews

11. SalesRoads – Best for appointment setting

Salesroads logo

SalesRoads is a demand generation agency that specializes in helping companies grow their sales through outbound strategies. T

They are mainly known as a B2B appointment setting agency.

SalesRoads mainly focuses on using cold calling, email outreach, and sales development tactics to find potential customers.

They have 16 years of experience as a b2b demand gen agency.

Pros

  • 16 years of experience

  • Clients are happy with the quality of leads

  • US-based SDRS

Cons

  • They are quite expensive compared to other agencies

  • They only focus on outbound lead generation

  • They are mainly focused on cold-calling

Best for

SalesRoads is a good fit for B2B companies that still rely on cold calling.

If you’re in an industry such as industrial, manufacturing, or complex B2B services, their experienced SDR team tends to resonate more than an automated email.

They’re also worth considering if you’ve tried outsourcing cold calling before and ended up with junior reps reading off a script.

SalesRoads puts more experienced callers on the phone and builds custom playbooks around your offer rather than recycling a generic approach.

That said, if phone isn’t a primary channel for your buyers, or you’re looking for a more multichannel-first strategy, there are probably better options out there.

Pricing

All SalesRoads prices start at $9400 per month. You would have to reach out to them for a more tailored pricing plan.

Reviews

SalesRoads received a 5-star rating, according to G2.

Directive consulting homepage screenshot

Rather than chasing traffic or form fills, they build demand programs around pipeline and revenue.

This means connecting paid media, SEO, content, and revenue operations into one strategy. Their “Customer Generation” methodology is built around the idea that the goal isn’t leads, it’s customers.

14. Powered by Search – Best For Content Marketing

Powered by search homepage screenshot

Powered by Search is a B2B SaaS marketing agency that has spent over a decade doing one thing, and that’s helping SaaS companies build a predictable pipeline.

They don’t work with everyone.

If you’re not a B2B SaaS company, then they won’t be a good fit.

Their approach is built around what they call the “Predictable Growth Model”, which is a three-step framework that focuses on getting in front of the right decision-makers, making them an offer they can’t refuse, and then building a repeatable acquisition model that grows over time rather than resetting every quarter.

They cover all things marketing from paid ads, SEO, ABM, content marketing and digital PR.

One thing that sets them apart is transparency.

They publish their playbooks and methodology openly so you can understand how they think before you ever get on a call with them.

Pros

  • Works only with B2B SaaS

  • Integrates paid, organic, and RevOps into one unified program

  • Strong track record with companies ranging from $1M to $100M ARR

Cons

  • Not suitable for companies outside B2B SaaS

If you’re still figuring out product-market fit, they’re probably more than you need right now.

Pricing

You would need to reach out to them directly for pricing, as they don’t mention pricing on their website.

Review

Unfortunately, they don’t have third-party reviews, but according to their site, they have many testimonials on their website that you can view.

15. Ironpaper – Best for digital marekting

Iron paper homepage screenshot

Ironpaper has been around since 2003. Founded in New York City, they’ve spent over two decades focused on B2B, specifically helping companies with long or complex sales cycles generate qualified leads, build pipeline, and grow.

What makes them different from a typical digital marketing agency is how seriously they take the connection between marketing and sales.

They’re not just running campaigns and handing over a spreadsheet of contacts; they work across demand generation, ABM, content strategy, and sales enablement with the goal of growth, not just driving traffic.

Pros

  • Over 20 years of B2B experience

  • Good experience across demand gen, ABM, content, and sales enablement

  • Focus on metrics that actually matter rather than vanity numbers

  • Works across a wide range of B2B industries, including SaaS, IT, and manufacturing

Cons

  • Pricing is not published

  • Their methodical, strategy-first approach may feel slow if you need fast results

  • Less suitable for companies that need pure outbound or cold outreach

Best for

Ironpaper is a good fit for B2B companies in tech, SaaS, IT, or manufacturing sectors where the sales cycle is long and involves multiple stakeholders.

If your biggest challenge is that marketing and sales aren’t aligned, or that you’re generating leads that never seem to convert, they’re the kind of agency that digs into the underlying problem rather than just throwing more budget at it.

Pricing

Ironpaper doesn’t publish pricing on their website. Contact them directly for a quote based on your goals.

Reviews

Ironpaper has a 4.8-star rating out of 5 on G2.

Clients mention how they love their strategic depth, responsiveness, and ability to work as an extension of an internal team.

Demand generation agency FAQs

What is demand generation, and why does it matter for B2B businesses?

Demand generation is the process of building interest in your product or service, not just collecting contact details, but actually getting the right people to care about what you do.

For B2B companies, it matters because without a good flow of interested, qualified buyers, your sales team is essentially starting from scratch every quarter.

Successful demand generation brings sales and marketing together around a shared goal: filling the pipeline with people who actually want to buy.

Can a demand generation agency actually make a difference?

Yes, definitely, BUT, it depends on which company you choose. A good demand generation marketing agency brings their expertise, tools, and strategy to reach your ideal buyers and turns them into marketing opportunities and sales deals.

A bad agency could burn your budget on activities that look good in a report but never turns into revenue.

That’s why doing your homework before signing anything is so important.

Is hiring a lead generation company worth it?

Again, it comes down to the agency. Some consistently deliver leads and meetings, others don’t.

Before committing, ask detailed questions about their process, what success looks like, and how they measure results.

Demand generation agency vs. digital marketing agency, which is better?

A digital marketing agency focuses on visibility, like SEO, paid ads, social media, and email marketing.

A demand generation agency takes a more cohesive approach, focusing on pipeline generation, getting the right people into a buying conversation and keeping them there.

Neither is automatically better; it depends on your strategic priorities and where your biggest gap is.

That said, if you can use both, you’ll almost always see stronger B2B growth than relying on one channel alone.

Finding the Right Partner for Sustainable Growth

Choosing the right B2B demand generation services isn’t just a marketing decision but a strategic one.

The agencies on this list all take different approaches, but the best ones share a few things in common:

  • Disciplinary demand generation teams that bring many skills together
  • A clear focus on pipeline generation over vanity metrics
  • And the ability to align sales and marketing so they work as one.

Need the right agency?

Before reaching out to anyone on this list, get clear on your strategic priorities.

What works as a marketing practice for one company won’t necessarily work for another.

The goal isn’t to find the biggest agency or the most well-known name, but it’s to find the team that understands your buyers, can deliver real commercial results, and has the experience to build demand generation systems that actually move revenue in the right direction.
