Lead generation companies are businesses that help you find and attract new leads that fit your ideal customer profile. Most serve B2B clients, and the top ones offer a tailored strategy that includes engaging with leads via social media or inbound and outbound marketing, then researching and qualifying leads, and finally nurturing leads to some extent. To help you choose the right company, we’ve listed the best options and how they generate leads for you.
Here are the top seven lead generation companies for quality leads:
Although some companies had high scores in one category or another, Callbox offers the best overall value for those looking for a company to help generate qualified leads. If you’re looking for a lead gen company specifically for B2B leads, check out our guide to the top B2B lead generation companies. Otherwise, keep reading or jump below to see how we scored and evaluated each option.
Provides access to an array of progressive sales and marketing tools to help productivity and efficiency.
Callbox is a B2B lead generation company that uses targeted B2B data and advanced sales and marketing tools to identify, expand, engage, and convert qualified leads. They compile a list of target companies matching your ideal customer, then generate leads for you via calls, emails, social media, live chat, ads, and landing pages. In addition to lead generation and appointment setting, they provide webinar and cross-border marketing.
While Callbox is a strong agency offering advanced features, the only CRMs they integrate with are Callbox Pipeline and HubSpot. If you’re looking for a more adaptable lead generation company with integration capabilities, check out RevBoss.
Identifies and engages with pre-qualified leads through a variety of outreach strategies on your behalf.
LeadGeneration.com is a lead generation agency that assigns entire management teams to your business that create custom and multichannel campaigns. Since every market and industry is different, their outreach strategies include SEO, content distribution, email marketing, website development, call tracking, and appointment setting. Your custom campaign will include a mix of these strategies based on your target audience to fill your pipeline with verified opportunities.
Even with a variety of online marketing strategies that create a cohesive lead gen program, LeadGeneration.com doesn’t offer direct cold calling services. If that’s an outreach strategy you want from an agency, check out Callbox for their cold calling and emailing services.
Uses an AI-powered platform to generate leads with data sources, sales content, chat, and email interactions.
CIENCE self-identifies as a People-as-a-Service (PaaS) company that specializes in domestic and international lead generation. Their services include access to an in-house platform that uses advanced artificial intelligence (AI) to source, score, engage, and track leads. For example, the platform can add an AI live chat feature to your website to strategically communicate with your business’s web page visitors and turn them into leads to be nurtured.
CIENCE offers a free tier, but it gives limited access to their services and only 10 leads a month. If you’re a mid- to large sized business, you’d need to invest in higher tiers to use their platform and full services. If you’re wanting a similar option for a lower cost, check out RevBoss.
Specializes in creating customized marketing campaigns backed by B2B data to target your ideal customer profile.
EBQ is a lead generation company with a holistic approach to pipeline growth, helping in every stage of the buyer journey. In addition to outsourcing sales, they operate as a full service marketing company. They offer personalized digital and content marketing on top of website development and visual design. This way, your online presence is customized to attract and engage with the qualified leads you’re targeting.
EBQ offers advanced marketing and data services, but their outreach and appointment strategies are limited compared to the market standard. If you’re looking to focus on advanced outreach efforts, look into Callbox for their multitouch and multichannel approach.
Offers a software platform housing campaigns that sync directly to your sales tech stack including CRM software.
RevBoss is a lead gen company that focuses on outbound generation by offering in-house sales prospecting software. Their support team builds custom integrations to automate data exchanges between RevBoss and your CRM to update your sales funnel with the newest qualified leads. It also connects to your calendar and emails. This way, your entire sales team can track and monitor the lead generation progress from your existing sales tools.
RevBoss specializes in marketing, technology, consulting, and start-up industries. If your business doesn’t fall under one of these specific categories, check out Callbox for their diverse industry specializations.
Uses role-based targeting to book phone calls, virtual, or in-person appointments with qualified leads.
UnboundB2B is a demand generation agency that offers end-to-end sales enablement services, from database management to appointment setting. They focus on precise engagement and pipeline acceleration to target high-quality leads and immediately funnel them into your sales process while intent is high. They’ll confirm appointments on your behalf with interested decision-makers, and you only need to pay for successful appointments.
While UnboundB2B can target and pass qualified leads to you, they don’t nurture leads beyond appointment setting. If you want an agency that regularly engages leads through multiple channels, check out Callbox.
Assigns you a sales operation manager and delivers a customized strategy within a few days after signing.
Martal Group is a lead generation and sales company that has access to 100 million contacts. They offer three tiers dictating how far they take the most appropriate leads from their database through your buyer journey: inbound and outbound lead gen, customer onboarding, and/or account management. They invest up to 20 hours in the first week after signing to learn about you, strategize, and finalize your marketing materials, so consider them for quick leads.
Even though Martal Group offers a full scope of lead generation services from targeting prospects to flipping leads, you might be looking for leads on a larger scale. In that case, consider Callbox for their international outreach capabilities.
The four most popular offerings by lead generation companies include:
The agency considers your target market and creates personalized inbound and outbound lead generation campaigns, such social media advertising, marketing content, and actual cold calling or cold emailing touchpoints.
To find the top lead generation companies available, we first determined our scoring criteria and organized them into the six categories below. Next, we used detailed key subcriteria to assign each lead generation company a score out of five for each category. The category scores totaled an overall score for each company on our list, which we used to identify an ideal use case.
We prioritized the pricing and core services offered by each lead generation company. Next, we evaluated advanced offerings. From there, we scored what unique technology offerings are provided, as well as their customer service and reporting capabilities.
We evaluated the minimum price clients can expect to pay, sample leads or trials offered, billing options, and cost transparency.
We investigated if the companies research and qualify leads for each client, focus on intent, conduct outbound and inbound marketing, and offer cold calling or emailing.
We looked for advanced offerings like industry specialization, lead scoring and nurturing, and if you receive assigned sales development representatives (SDRs).
Some companies provide designated account managers to customers. We checked for that service, as well as phone, live chat, and email contact options.
We reviewed whether companies offered CRM integrations, access to a client database of leads, improvements to clients’ websites, or any AI functionality.
We scored companies on whether they build out lead databases, offer lead generation or engagement reporting, and overall campaign performance tracking.
Choosing a lead generation company that best serves your goals will allow you to attract more qualified leads, onboard them as new customers, and maintain relationships with them. Consider requesting a consultation or quote from any of the seven companies we’ve mentioned here.
