What to Look for in a Lead Gen Company

Technology platform

Does the company have a proprietary AI platform, or do they resell third-party tools at a markup? Proprietary platforms mean better data, faster iteration, and no extra data subscription cost.

SDR pricing model

Most agencies mark up SDR costs 30–50%. At-cost models (like CIENCE's Talent Cloud) give you the same talent at significantly lower rates with no hidden margins.

Contract flexibility

Multi-month minimums (3–6 months) are standard in this industry and often catch buyers off-guard. Month-to-month contracts let you evaluate before committing.

Research backing

Sales development is a discipline with measurable best practices. Companies backed by dedicated research organizations (like Tenbound for CIENCE) apply validated methodology instead of guesswork.

Choosing a B2B Lead Generation Company — FAQ

How do I choose the right B2B lead generation company?

Compare four things: technology (do they have a proprietary AI platform or rely on third-party tools?), pricing model (agency markup vs at-cost), contract flexibility (month-to-month vs multi-month lock-in), and proof (named case studies and client logos, not just testimonials). CIENCE is built on the graph8 AI platform with intent data included, offers at-cost SDR pricing through the Talent Cloud, requires no long-term contract, and has 115 named case studies across 151 industries.

What is the graph8 platform and why does it matter?

graph8 is the AI-powered go-to-market platform that CIENCE is built on. It includes intent data, audience intelligence, and multichannel campaign orchestration across email, phone, LinkedIn, and programmatic ads — all included at no extra cost. Most lead gen companies pay separately for data enrichment and outreach tools. CIENCE clients get the full graph8 platform built in.

What is Tenbound and why does it differentiate CIENCE?

Tenbound is a sister brand to CIENCE — the only dedicated sales development research and training organization in the industry. No other lead gen company has an affiliated research and training arm. Tenbound methodology and benchmarks are built into how CIENCE runs SDR programs, which means clients benefit from industry-leading research on what actually works in sales development.

How much does CIENCE cost compared to other lead gen companies?

CIENCE starts at $2,000/month for campaign management plus at-cost SDR rates of $1,500–$5,500/month depending on experience level. Most competitors charge $5,000–$15,000/month with 3–6 month minimum contracts. Because CIENCE uses the Talent Cloud to hire SDRs at cost (no agency markup), clients typically save 30–60% compared to traditional agencies.

Does CIENCE require a long-term contract?

No. CIENCE offers month-to-month contracts with no long-term commitment required. Most competitors in this comparison require 3–6 month minimums. Month-to-month contracts let you evaluate results before committing, and scale up or down as your pipeline needs change.
