Every B2B company faces the same challenge: How do you generate enough qualified leads to hit your revenue goals?
You have three options: build an in-house lead generation team, partner with a specialized agency, or create a hybrid model. Each approach has distinct advantages and drawbacks.
After helping 200+ companies optimize their lead generation strategies, we’ve seen what works (and what doesn’t) across every model. Here’s your complete guide to choosing the right approach for your business.
In-House Lead Generation: Complete Control, Higher Costs
The In-House Advantage
- Deep product knowledge: Your team lives and breathes your solution
- Cultural alignment: Perfect brand representation in every interaction
- Long-term investment: Skills and relationships stay with your company
- Direct oversight: Complete control over processes and priorities
The Hidden Costs of Going In-House
Building effective lead generation internally costs more than most companies expect:
Hiring Costs:
- Senior SDR: $65K-$85K salary + benefits
- SDR Manager: $90K-$120K salary + benefits
- Recruiting and onboarding: $10K-$15K per hire
Technology Stack:
- Sales engagement platform: $2K-$5K/month
- Data providers: $500-$2K/month
- CRM optimization: $1K-$3K/month
Time to Results:
- 3-6 months to hire and train new SDRs
- 6-12 months to optimize processes and see consistent results
- Ongoing management overhead for sales leadership
Reality Check: Most companies underestimate the total cost of in-house lead generation by 40-60%.
Agency-Based Lead Generation: Faster Results, Specialized Expertise
Why Companies Choose Agencies
- Immediate expertise: Proven processes and experienced team from day one
- Faster time-to-market: Start generating leads within 2-4 weeks
- Predictable costs: Clear monthly fee vs. variable hiring/training costs
- Scalability: Ramp up or down based on business needs

Hybrid Model: Best of Both Worlds
How the Hybrid Model Works
Combine internal sales development with specialized agency support:
Internal Team Handles:
- High-value enterprise accounts
- Complex, long-term relationship building
- Product demos and technical discussions
- Account-based marketing coordination
Agency Partner Handles:
- Mid-market prospect identification and qualification
- Initial outreach and interest generation
- Lead nurturing and appointment setting
- Market expansion and new vertical testing
When Hybrid Makes Sense
- Growing companies (50-200 employees) scaling sales operations
- Resource constraints prevent full in-house team building
- Market testing new segments or geographies
- Seasonal businesses with fluctuating lead generation needs
