Image: UnboundB2B

Our star rating: 3.4 out of 5

UnboundB2B is a demand generation company that supports both demand and lead generation for B2B marketers and sellers. After collecting true purchase intent data from buyers of your solution, it uses an AI-powered program that takes that behavioral data to create intuitive and hyper-specific campaigns to generate, qualify and nurture those leads.

Why we chose UnboundB2B

UnboundB2B prequalifies each lead it sources before funneling them into your pipeline. It uses the popular qualification framework, BANT. This method of lead qualification includes learning the budget, authority, need and timeline of the lead in that order. Holding budget at the forefront ensures the lead would be able to afford your solution, and then, if they’re the decision maker for the purchase, what their specific need is and what’s their ideal timeline.

While UnboundB2B offers AI automation, lead scoring and reporting, its services are only meant for companies looking for B2B leads. If your clients aren’t B2B, consider ReBoss for their ad creation features that will attract your exact audience.

Key features of lead generation companies

Since most have custom pricing tiers or plans, the partnership between you and a lead gen company can be adapted to your existing sales process. Though you can mostly pick and choose which top features you want, there are core offerings that make investing in a lead gen company worth it. This includes campaign creation, lead scoring, presence of a dedicated account manager, industry specialization and appointment setting capabilities.

Campaign creation

Custom campaigns include all the strategies and methods the lead gen company will implement to begin pulling high-quality leads, including how and when they’ll begin actually engaging and nurturing leads for you. Campaign strategizing typically happens during the onboarding process with a lead generation company, and with the best lead gen companies, your campaign will adapt with the growth or changes of your business or market.

Lead scoring

Lead scoring is when the lead gen company has segmented leads by identifying where each lead is in their buyer’s journey, what their sense of urgency or budget is and how likely they are to make a purchase with you. Lead scoring helps organize incoming leads from the provider and better align your sales and marketing efforts.

Dedicated account manager

Most lead generation companies assign a dedicated account manager or an entire team of SDRs to your account and business. They’re meant to be your main point of contact with the provider and your go-to resource for updates on metrics, account details, lead funneling and more.

Industry specialization

Industry specialization is when a lead generation company has specific tools or insight in your industry, making its campaigns hyper-specialized for your target audience. This could be a focus on targeting and engaging technology leads, finance leads or law leads.

Appointment setting

Once a lead generation company solidifies a list of qualified leads for you, it contacts those leads to schedule a meeting with you or one of your sales reps. This way, your reps already have all the research and prep done and can focus entirely on those confirmed appointments and their selling strategy.

How do I choose the best lead generation company for my business?

Now that you have a complete list of the top lead generation companies in the market, it’s time to narrow them down to find the provider that aligns best with your sales process and allocated budget. The next step is to request quotes and sign up for any available demos or test pilots. This way, you’re able to directly communicate with the lead generation company and begin conceptualizing how their services can get your business where you want it to be.

Some questions you might consider asking when questioning these lead generation companies can be:

  • How quickly and how many leads can be funneled into the sales pipeline?
  • What is the total in-market expertise for your solution or industry?
  • What methods of inbound or outbound prospecting does the company use to engage with leads?
  • Are their services within your budget?
  • Does the company have its own management software, or does it integrate with your existing sales CRM?

Methodology

I followed an outlined criteria to select what lead generation companies to score using a rubric, then took the top scoring companies to review and assign an ideal use case. I also used an in-house algorithm that calculates a total star rating for each company, which includes the following breakdown:

  • Cost: Weighted 25% of the total score.
  • Core offerings: Weighted 25% of the total score.
  • Advanced offerings: Weighted 20% of the total score.
  • Tech features: Weighted 10% of the total score.
  • Reporting and analytics: Weighted 10% of the total score.
  • Customer support: Weighted 10% of the total score.
