    Need a lead list for your vertical? Skip list brokers like ZoomInfo. Learn the 3 reasons they fail and the 5 better sources for building a real vertical list.

    Need a lead list for your vertical?

    Don't do what everyone else does: buy a list from a broker like ZoomInfo.

    3 challenges of using the ZoomInfo's of the world:

    • Your target vertical and their taxonomy don't always line up

    • Their taxonomy categories can be general, causing you to buy leads you can't use

    • Sourcing vertical leads requires custom techniques that don't scale, so they don't do it

    So don't waste your time or money on list brokers. 

    Instead, use these 5 other sources:

    • Vertical associations

    • Vertical online directories

    • Vertical conference lists

    • Vertical online groups

    • Vertical competitor websites

    Frequently Asked Questions

    Why don't list brokers like ZoomInfo work well for vertical-specific lead generation?

    Because their taxonomy often doesn't line up with a specific target vertical, and their categories tend to be too general, leading to purchased leads that don't actually fit the intended audience.

    Why can't list brokers source vertical-specific leads more precisely?

    Because sourcing truly vertical leads requires custom techniques that don't scale well across a broad platform. Since that kind of precision doesn't fit their business model, brokers generally don't offer it.

    What are the better alternatives to buying a list from a broker?

    Vertical associations, vertical online directories, vertical conference lists, vertical online groups, and vertical competitor websites, all sources that reflect the actual vertical more precisely than a broad, general database.

    Why do vertical associations and conference lists tend to produce better leads?

    Because they're built around the specific community being targeted, rather than a generalized taxonomy that doesn't map cleanly onto any one vertical.

    Why look at competitor websites as a lead source?

    Because competitors often reveal exactly who they're serving, client lists, case studies, and testimonials, which can indirectly point toward the same pool of prospects worth targeting directly.
