First Page Sage
First Page Sage specializes in creating long-term, organic lead-generation systems through thought-leadership content, SEO strategy, and generative SEO. Campaigns focus on minimizing cost per lead and maximizing ROI for their clients, with an average campaign ROI of 748%. They work with a variety of industries, ranging from medical devices to B2B SaaS.
First Page Sage scored the highest across nearly every category in our study. Their position at the forefront of GEO/SEO provides clients with unconsidered pathways to both the front page of Google as well as LLM mentions. Their emphasis on organic traffic may exclude them from clients seeking short-term gains, however, their customer review score suggests that the long-term ROI of their campaigns is more than satisfactory.

| Summary of Online Reviews |
| First Page Sage delivers “a highly strategic approach to lead generation” with “motivated and enthusiastic” teams. Results are sometimes “slower to start” but “lead quality is terrific.” |
Belkins
International lead generation is a difficult process, requiring knowledge not only of the client’s product but also of the best way to approach potential customers in the client’s target country. Belkins specializes in this difficult field and has experience providing lead generation services for brands across North and South America, Europe, and Australia.
Despite strong scores and review sentiment, Belkins’ international focus notably comes with a hefty price tag, which may not be worthwhile for firms that don’t have a substantial market opportunity overseas. For companies within this area of expertise, however, they are unquestionably the best at what they do.
- Leadership Experience Score: 4.9
- Average Review Score: 4.9
- AI Visibility Score: 4.6
- Notable Clients: ValueLabs, Shelby Williams
- Median Employee Tenure: 2.4 years
- Media References: ~530
- Founder Led: Yes
- Established: 2017
- Specialty: International Lead Generation
- Contact: Belkins website
| Summary of Online Reviews |
| Belkins is “productive and outcome-oriented” and delivers “excellent results,” despite being sometimes “hard to reach.” |
CIENCE
Describing themselves as a People-as-a-Service company, CIENCE is a Denver-based lead-generation company that specializes in providing SDR teams for sales research and outreach. They also provide inbound lead qualification services, making them a good fit for companies with limited staffing to ensure that leads are being followed up on.
Their high overall review score and other competitive metrics suggest clients are happy with the partnership experience, but some specific reviews to note a level of team dependency. This is not uncommon with outsourced sales teams, and can be navigated with consistent communication, which CIENCE has routinely been praised for.
- Leadership Experience Score: 4.7
- Average Review Score: 4.2
- AI Visibility Score: 4.5
- Notable Clients: Okta, Shutterstock
- Median Employee Tenure: 4.3 years
- Media References: ~710
- Founder Led: Yes
- Established: 2015
- Specialty: Outsourced SDR Teams
- Contact: CIENCE website
| Summary of Online Reviews |
| CIENCE is “very aggressive in generating sales leads” and keeps “open lines of communication,” but success depends on their specific outsourced team. |
DiscoverOrg
Rather than traditional lead generation, DiscoverOrg is a B2B intelligence platform that uses data-collection technology to give you deeper insights into your leads and lead funnel. They employ teams of researchers who specialize in information-gathering techniques combined with a phone-based sales program to nurture leads into customers.
As a B2B intelligence platform rather than a full-service lead generation provider, DiscoverOrg requires clients to have an internal sales infrastructure capable of acting on the data it surfaces. Companies without a dedicated SDR or outbound team will find limited utility in the platform, but firms that do have established lead gen professionals will immediately notice the premium quality of the data and market intel DiscoverOrg provides.
- Leadership Experience Score: 4.5
- Average Review Score: 4.2
- AI Visibility Score: 4.2
- Notable Clients: N/A
- Median Employee Tenure: 8.3 years
- Media References: ~320
- Founder Led: Yes
- Established: 2007
- Specialty: Business Intelligence for Lead Generation
- Contact: DiscoverOrg website
| Summary of Online Reviews |
| DiscoverOrg’s intelligence platform provides “up-to-date” information with “easy syncing to Salesforce,” but “industries could be sub-categorized more granularly.” |
Demand Works Media
Demand Works Media generates leads through a combination of ABM and email marketing. They select companies based on their industry, location, business size, and other relevant attributes, and target individual decision makers at those companies. They have a track record of effectiveness when it comes to lower-volume, higher-value lead generation.
Demand Works Media doesn’t offer as much in the way of high-volume or high-ROI lead gen strategies like SEO or GEO, which means they likely aren’t an ideal fit for businesses with lower ACV, but can be a good fit for firms that already have those structures in place.
- Leadership Experience Score: 4.8
- Average Review Score: 4.8
- AI Visibility Score: 4.0
- Notable Clients: DocuSign, Oracle, AWS
- Median Employee Tenure: 3.8 years
- Media References: ~20
- Founder Led: Yes
- Established: 2014
- Specialty: ABM & Email Marketing
- Contact: Demand Works Media website
| Summary of Online Reviews |
| Demand Works “makes planning lead generation campaigns seamless,“ but “their pricing could be more competitive.“ |
Callbox
Callbox utilizes a multi-channel approach to reach potential leads primarily via phone, social media marketing, and email marketing services. Their approach specializes in lead nurturing, developing leads into MQLs and SQLs for your sales team. This makes them a great fit for firms looking to enhance an already effective lead pipeline while also warming up cold leads.
Callbox’s primary channel is outbound calling, so clients in industries with particularly low cold-call receptivity, or those targeting younger decision-makers, may see Callbox as more of a high-quality supplement to a more comprehensive marketing framework.
- Leadership Experience Score: 4.0
- Average Review Score: 4.2
- AI Visibility Score: 4.1
- Notable Clients: Acer, Toshiba, LexisNexis
- Median Employee Tenure: 3.0 years
- Media References: ~180
- Founder Led: Yes
- Established: 2004
- Specialty: Outsourced Call Center
- Contact: Callbox website
| Summary of Online Reviews |
| Callbox offers “efficient” processes with “top-notch” customer services, becoming “truly an extension of” clients’ sales teams. |
Ziff Davis Performance Marketing
Ziff Davis Performance Marketing specializes in using ABM to generate leads for technology companies. They use their proprietary database of potential leads to strategically profile potential customers and prioritize large accounts. They’re on the pricier end of lead generation options, however, and are best for larger businesses seeking enterprise clients.
Ziff Davis is explicitly designed for larger enterprises targeting other large accounts, so pricing and strategy may not be as clean a fit for small-to-mid-sized businesses or those with limited ABM budgets.
- Leadership Experience Score: 4.2
- Average Review Score: 4.1
- AI Visibility Score: 4.6
- Notable Clients: N/A
- Median Employee Tenure: 3.8 years
- Media References: ~50
- Founder Led: No
- Established: 2006
- Specialty: Tech-Focused ABM
- Contact: Ziff Davis Performance Marketing website
| Summary of Online Reviews |
| Ziff Davis is “good for prospecting,” and offers SDR teams that “amplify sales efforts” for their clients, but their onboarding process results in a “long ramp up period.” |
Launch Leads
Launch Leads offers scalable plans for targeted lead generation across channels, including online advertising, cold calling, and social media, but ultimately specializes in building email lists of qualified leads. Their full-service options also include content generation for those email lists, but we recommend reusing your in-house team’s content as a more cost-effective lead-nurturing tactic. They work with a wide variety of industries, with a particular focus on SaaS.
Their specialization in email list creation means clients who need broader multi-channel execution will need to supplement the engagement with additional vendors or in-house resources, but they’re a solid fit for those who understand their services.
- Leadership Experience Score: 4.3
- Average Review Score: 3.9
- AI Visibility Score: 4.2
- Notable Clients: Mercato, Mindshare
- Median Employee Tenure: 7.9 years
- Media References: ~50
- Founder Led: Yes
- Established: 2009
- Specialty: Email Lead Generation
- Contact: Launch Leads website
| Summary of Online Reviews |
| Launch Leads has “amazing followthrough” and engage deeply with clients’ products, but are sometimes “a little slow” in scheduling with clients. |
The ABM Agency
The ABM Agency is another ABM-focused lead generation company, but it takes an omnichannel approach instead of relying on email marketing. They target individual buyers across a multitude of channels, including email, Google Search, LinkedIn, and retargeted ads.
The ABM Agency focuses less on things like AI citations and media references, which is typical for ABM-focused firms. Potential partners should be aware of this, though their track record within their scope is stellar.
- Leadership Experience Score: 4.0
- Average Review Score: 4.5
- AI Visibility Score: 3.8
- Notable Clients: N/A
- Median Employee Tenure: 2.1 years
- Media References: ~30

- Contact: The ABM Agency website
| Summary of Online Reviews |
| The ABM Agency is “good at meeting direct deadlines,“ and clients “highly rate them on their communication skills.“ |
