What Do Lead Generation Companies Do?
Lead generation companies find and qualify potential customers for your business. Depending on the company, they may handle:
- Prospecting — identifying target companies and contacts
- Outreach — sending cold emails, LinkedIn messages, or making calls
- Qualification — filtering responses to identify genuine interest
- Appointment setting — booking meetings on your sales team's calendar
Some handle the full funnel. Others specialize in one piece. The best ones feel like an extension of your sales team.
Types of Lead Generation Companies
1. Outbound Agencies (Done-for-You)
They build and manage your entire outbound operation — lists, messaging, sending, follow-ups, and appointment setting.
Typical cost: $3,000-$15,000/month Best for: Companies without an in-house SDR team Delivery: Booked meetings or qualified leads
2. Lead List Providers (Data)
They sell contact databases — names, emails, phone numbers, company data.
Typical cost: $0.10-$1.00 per lead (varies by data quality) Best for: Teams with their own outreach capability Delivery: CSV or CRM-integrated contact lists
3. Intent Data Providers
They identify companies actively researching solutions like yours — based on content consumption, search behavior, and technographic signals.
Typical cost: $1,000-$10,000/month Best for: Targeting accounts that are already in-market Delivery: Account lists with intent scores
4. Pay-Per-Lead Services
You pay a fixed amount per qualified lead delivered. The company handles all prospecting and outreach.
Typical cost: $50-$500 per lead (depending on industry and qualification criteria) Best for: Companies that want predictable unit economics Delivery: Qualified leads or booked meetings at a fixed cost
5. Inbound Lead Generation (SEO/Content/Ads)
Companies that generate leads through content marketing, SEO, or paid advertising — driving prospects to you rather than reaching out to them.
Typical cost: $2,000-$20,000/month Best for: Long-term pipeline building alongside outbound Delivery: Website traffic, form fills, demo requests

How to Evaluate a Lead Generation Company
1. Ask About Their Process
Good companies will walk you through exactly how they find, qualify, and deliver leads. Red flag: "We have a proprietary system" with no details.
2. Check Their ICP Match
Do they have experience in your industry and target market? A company that generates leads for enterprise SaaS may not be effective for a local service business.
3. Understand the Pricing Model
- Retainer: Fixed monthly fee regardless of results (risky for you)
- Pay-per-lead: Fixed cost per qualified lead (more aligned incentives)
- Hybrid: Base retainer + per-lead bonus (most common)
4. Define "Qualified Lead"
The #1 source of conflict with lead gen companies: misaligned definitions. Get specific:
- What criteria must a lead meet?
- Who decides if a lead is qualified?
- What happens with unqualified leads — do you still pay?
5. Ask for Recent References
Not case studies on their website — actual references you can call. Ask about lead quality, communication, and whether the ROI justified the cost.
6. Check Contract Terms
Avoid long-term contracts (12+ months) with unproven vendors. Start with a 3-month pilot.
Red Flags to Watch For
🚩 "Guaranteed" lead numbers — No one can guarantee volume without sacrificing quality 🚩 No transparency on sourcing — Where do the leads come from? Purchased lists? 🚩 Long-term contracts upfront — Good companies earn your renewal, not lock you in 🚩 No qualification criteria discussion — They should ask about YOUR ideal customer 🚩 Extremely low prices — $500/month for "100 qualified leads" means the leads aren't qualified 🚩 Generic messaging — If they send the same templates to every prospect, expect low conversion
Build vs Buy: When to Use a Lead Gen Company
Use a Lead Gen Company When:
- You don't have an in-house SDR team and can't hire one yet
- You need to validate a new market or ICP quickly
- You want to supplement an existing team's capacity
- You're entering a new geography and lack local expertise
Build In-House When:
- Outbound is core to your business model
- You need deep product knowledge in conversations
- You're at a scale where the cost per lead from agencies is too high
- You want full control over messaging and targeting
The Best of Both Worlds
Many companies use lead gen agencies to start, learn what works, then bring it in-house and automate with tools.
Handshake helps you build your own LinkedIn outbound engine — so you keep the pipeline, the data, and the relationships in-house:
- Automated prospecting — find and connect with your ideal customers
- Personalized sequences — multi-step campaigns that feel human
- Scale without agencies — run outbound at a fraction of the cost
- Full control — your messaging, your targeting, your results
Why rent a pipeline from an agency when you can own one?
FAQ
How much should I pay per lead?
It depends on your average deal size. A rough rule: your cost per lead should be under 5% of your average contract value. If your ACV is $50K, paying $500-$1,000 per qualified lead can be reasonable.
How long before I see results from a lead gen company?
Expect 4-8 weeks for initial setup and ramp. Meaningful results typically start in month 2-3. Any company promising results in week one is likely not qualifying properly.
Can I use multiple lead gen companies at once?
Yes, but be careful about overlap. Make sure they're targeting different segments or using different channels to avoid hitting the same prospects from multiple angles.
What's the average conversion rate from lead to customer?
Industry average: 2-5% of qualified leads convert to customers. Top-performing teams see 10-15%. The variance depends heavily on lead quality, sales process, and product-market fit.
Stop renting leads. Build your own pipeline. Handshake automates LinkedIn outreach so you generate leads in-house — cheaper, faster, and fully under your control.
