    What does a B2B lead generation agency do?

    A B2B lead generation agency finds businesses that fit your offer and turns them into sales conversations. That covers targeting, data, outreach, follow-up and booking, plus capturing and qualifying inbound interest. The output that matters is qualified meetings and pipeline, not a spreadsheet of contacts.

    Many agencies run campaigns on their own tools and hand over leads. FullStackCloser builds the system inside your stack, so the targeting, sequences, data and results stay connected to your CRM and keep improving after launch.

    How we build a lead generation system

    Each system is scoped in a written proposal and built in this order:

    • Target: define the ICP and buying triggers, then build and enrich account and contact lists.
    • Infrastructure: set up and warm sending domains, and connect your CRM, calendar and enrichment tools.
    • Message: write offers and sequences for each segment, personalized for each prospect with AI research.
    • Launch: run email and LinkedIn outreach, follow up automatically and route replies.
    • Optimize: track reply, meeting and pipeline rates by segment and message, and double down on what books meetings.

    Frequently asked questions

    What does a B2B lead generation agency do?

    It finds companies and people that fit your offer and turns them into sales conversations through targeting, data, outbound outreach, inbound capture, follow-up and appointment setting. A good agency measures success in qualified meetings and pipeline, not contacts delivered.

    What is the difference between lead generation and demand generation?

    Lead generation captures and converts buyers who are ready to talk now. Demand generation builds awareness and intent so more of the market is ready later. Outbound and inbound lead generation convert better when demand generation runs alongside them.

    How much do B2B lead generation services cost?

    Lead generation systems start at $3,500 as a Custom Build. A fully managed lead generation and outbound team is part of the Full Revenue Team engagement, from $13,500 per month plus revenue share. A $997 AI Strategy Session maps your targets and channels first.

    Is outsourced lead generation worth it?

    It's worth it when you have a proven offer and a clear ideal customer but not the time, expertise or infrastructure to prospect at volume. It won't fix an offer that isn't converting, and we'll tell you if that's the real problem.

    Which channels do you use?

    Mainly cold email and LinkedIn for outbound, backed by enrichment and intent data, plus inbound capture through your website, lead magnets and content. Everything connects to your CRM and calendar.

    How do you keep cold email out of spam?

    Dedicated sending domains with proper authentication, gradual warmup, deliverability monitoring, verified lists, sensible daily volumes and messages written for each prospect rather than one template blasted to everyone.

    How is this different from your outsourced SDR service?

    Lead generation is the whole system for creating qualified meetings, outbound and inbound. Our outsourced SDR service is the prospecting and appointment-setting function inside it, run by AI SDR agents. Most clients use them together.
