9 Lead Generation Companies That’ll Expand Your Reach in 2023 (How to Choose the Best Company)

Lead generation is a significant challenge for companies. Especially the process of nurturing a B2B lead can take several months, and fast response times are crucial for web leads. Hiring a lead generation company can alleviate this burden and allow marketers to focus on building customer relationships. While choosing a lead gen partner, it's important to assess their capabilities, reputation, data quality, and ROI expectations. So here are some top lead generation companies for 2023 that specialize in developing and implementing custom lead generation strategies that will assist in your decision-making process.


Lead generation is the hardest thing for every company, especially B2B Lead Generation Companies.
On average, it takes 4-6 months to nurture a new B2B lead. However, it can take even more, as you can see in this bar diagram:
B2B Sales cycles - New Vs. Existing customers
Besides taking a long time to decide, web leads hate waiting. They want a response from a company within 17 hours. Moreover, 9x leads drop off when they wait longer than 5 minutes.
That means leads prefer fast responses but take longer to decide.
And that makes marketers’ jobs harder. They can either be available for leads all the time or focus on improving lead generation strategies.
Many smart businesses have addressed this problem with a simple solution—hiring a lead generation company.
A lead gen agency is a team of creative and lead generation experts that works to develop and implement custom lead generation strategies. These companies can take over all your lead gen troubles, so you can focus on building customer experiences and relationships.
Today, many great lead generation companies are available in the market. But, finding a suitable one for your business takes time and effort.
But, no need to worry about it!
This post shows how to choose the perfect lead generation companies and top 9 agencies you can hire in 2023.

What Are the Main Lead Generation Company Types?

Lead gen companies are divided into categories based on the targeted industry, used technologies, and lead generation methods. Generally, there are two main lead gen company types:

Outbound lead generation agency

Outbound lead generation strategies are the most established. They are primarily done through emails, cold calling, and direct mailing.
While they are old-fashioned marketing methods, they have lasted longer due to their effectiveness.

Inbound lead generation agency

Inbound lead generation, on the other hand, occurs when agencies develop strategically designed content. It is intended to attract potential leads.
Content is typically the main inbound marketing weapon, such as social media advertisements, articles, and blog posts.

Why Must You Partner with a Lead Generation Company?

Here are compelling reasons to work with a lead generation agency:

Complete lead gen team’s support

Digital marketing is teamwork. Many professionals collaborate to launch successful lead generation campaigns, including copywriters, SEO experts, social media strategists, graphic designers, and many more.
Hiring an individual professional and managing them can suck up your marketer’s time. In contrast, agencies already have a digital marketing team that can help you achieve your goals in less time and without complexities.

Streamline your internal operations

The benefit of working with an agency is that they are not overburdened with your company’s day-to-day operations. Instead, their primary goal is to drive results for your company; this is how they add value to your organization and demonstrate their worth.
You can focus on other initiatives, goals, and priorities while an agency drives new leads to your company via your website.

Save your team

Outsourcing lead generation workload can save you time and money. For example, according to a study, B2B sales reps make 35 calls per day.
Finding the prospects and then calling them can take your sales reps all day, resulting in less focus on important operations like strategizing, relationship building, etc.
Thanks to agencies, your team doesn’t have to handle appointment scheduling and calling. Instead, they can either use the agency’s pre-built database or request them to build a custom contact base.

Set up lead targeting and follow-up strategy

Lead scoring is yet another way for your sales team to save time. For example, you can use lead scoring to determine when a lead is ready for your sales team to follow up – or if lead nurturing is a better option.
This type of process will help you build trust with your potential customers. It is critical to follow up with leads when they are ready to hear from you, but you can also scare a lead away by following up with them too early in the process.
But, the agency experts know when to pouch a lead before it turns cold or, leaks from your funnel.

Reduce the sales cycle

Sales-qualified leads are easy to identify when you have an established lead flow. It means it’s simple to recognize when buyers indicate that they’re ready to be approached by a salesperson.
Consider your actions when you’re in a store and ready to buy—you ask questions, gather information, and then seek a salesperson to assist you with the final purchase.
The same is true for online purchasers. When your lead generation agency can assist you in identifying key buyer research moments and mapping them to your buyer journey, it becomes simple to determine where your prospects are in the journey and connect with leads who are ready to buy.

How to Find the Best Lead Generation Company?

A good lead generation company can make or break your sales funnel. Thus, it is critical to partner with the right growth agency.
Here are some tips for choosing a perfect lead gen partner:

Explore and Identify your Lead Generation Issues

Connect with a wide range of potential contacts via B2B lead generation services, from those simply looking to know more about the product or service to leads that have an established understanding of the company and actively support its offerings. In this case, each type of lead is in a different stage of the purchasing cycle, where a certain percentage is falling under leads, while others are merely names in a contact list.
When you shortlist a lead provider, you must understand specific ways in which they will be beneficial to your company. Doing an objective survey of your marketing capacity and its ability to grow leads is a smart way to gauge the effectiveness of existing resources and how exactly a specialist might be of most use.
For instance, if you already have a sound email marketing strategy and the platform is showing strong numbers, there’s no point in hiring services that provide expertise on the same. Instead, if conversion rates are down because of misdirected content and unclear communication, this area will benefit from a lead gen company’s focus.

Reality Check on ROI Expectations

Calculating the ROI to buy leads is relatively easy, but a business organization should update the strategy depending on the kind of leads pursued. Unfortunately, many focus on the number of leads, even if they are low-cost because these show a significant increase in less time.
However, the quality of the leads suffers because most are not at the stage where they are willing to buy a product or service from your business so that the returns will take far longer. This is usually due to poor data sources provided by third-party companies. Therefore, it is important to treat time as a valuable commodity and review how much investment will be needed once the leads are purchased.

Shortlist the Well-Known Organizations

In today’s world, there is an overwhelming list of options available regarding companies or firms offering leads to B2B companies. However, an experienced company versus a newcomer will have a noticeable difference in the type of leads they sell and how sustainable they are.
Explore the reputation of shortlisted organizations by browsing their social media platforms, testimonials or feedback from previous clients on their websites, and independent reviews published online on different mediums.
Is the type of content on their website consistent and expressive? What kind of networks do they interact with? Do they offer fair and flexible budget plans? Are their customers loyal?
These are markers for a long-term business, and more exposure to market conditions means better results. A prospective lead generation partner should be fully capable of delivering on their promises and increasing your lead quota instead of being all talk.

Assess the Quality of Data

It’s not enough to implement a new lead generation software and stop there. Your team needs to rigorously analyze whether the leads received are useful for your specific requirements. Most businesses get excited when they have a huge hike in the number of new leads, but if they don’t match your criteria, your situation is the same as before. Lead data must be utilized strategically, and only then will you see the results.
What distinguishes a great lead from others? First, look at the supplier’s existing portfolio and the protocols they execute to ensure lead quality is screened before reaching their clients.
More established agencies, such as UnboundB2B, guarantee the minimum number of leads to expect based on the priorities discussed. If the quality of your leads is improved, there will be visible changes on the marketing and sales front.

Don’t get fooled by lead aggregator companies aiming to make a quick buck through false and misleading advertising that encourages consumers to share a lead. Instead, choose sales to lead data perfectly tailored to potential clients and builds a personal connection with them.

Conversion Rates of Clients

Once you invest in a lead generation agency or firm, you should be getting returns linked to your business plans. The offered services must be able to fulfill multiple marketing goals and report back higher customer satisfaction rates.
Take a realistic approach to measure marketing and sales efforts, both from the business side and the lead generation agency concerned. Keep being proactive about doing the things that are working well, and focus less on the things that aren’t helping much.
Look out for suppliers who care about lead generation numbers without monitoring the long-term impact on customers’ needs. Instead, ensure you’ve got the best possible deal with software applications by checking the free trial versions and double-checking the conversion rates on different channels.

Review the Guarantees or Terms of Service

Before you seal the deal with a particular company, have a frank discussion on the kind of expectations you have in mind and what their services can realistically provide support for. Of course, it’s always great to hear from confident and capable professionals who give a guaranteed result. Still, vague statements and an unclear action plan are red flags for discontinuing negotiations.
Create a frequent communication channel that specifies the format, and establish who will be the point of contact on behalf of your team. Being open to feedback is vital for the company to be successful with your project, so be open to avoid any unnecessary misunderstanding. If things are going well, explore the possibility of longer collaborations instead of just the current assignment.
For many, the lead generation industry remains as unpredictable as ever, but many types of fish are in the sea. To figure out one best suited to your requirements, your marketing and sales team must do the necessary research and single out those organizations going the extra mile versus unverified agencies profiting from random contact lists.
Exceptional lead gen firms are pros at helping their clients master the market dynamics and create winning talking points that add to the brand. At the early stage, a business should take a closer look at the full scope of such an organization and what they offer to expand in a new market or streamline existing operations for better profitability.
