How it works

We find the project. Then the people behind it.

What takes your team an afternoon takes Groundwork minutes. So you call while the GC is still an open question.

  1. 01

    We watch your markets

    Filings, agendas and land sales in every county you cover. Your lead service alerts too, if you have them. Or just send us an address.

  2. 02

    We do the digging

    Who's behind the LLC, whether they're a real developer, and who picks the GC.

  3. 03

    You get a pursuit brief

    One page. Every fact sourced. An opener ready to send.

The pursuit brief

Everything you need to make the call.

Who's behind it, who decides, how to reach them, and how we know. Then the note, written for you to edit.

Subject 3018 N Clybourn: Planned Development application, GC not yet named
Dana,

Castellano Builders in Elmhurst saw Northline's Planned Development application for 3018 N. Clybourn on the September Plan Commission agenda: five stories, 24 units, replacing the one-story commercial building.

We build multifamily, mixed-use and climate-controlled storage across Chicagoland in the $5–40M range. If you're still selecting a GC for Clybourn, we'd welcome fifteen minutes this month to walk a comparable job.

How we know

We never make up a name.

Your firm's name is on the note. The bar is high.

  • Exact match

    Every name appears, spelled that way, on a public page you can click.

  • Two sources

    A person isn't confirmed until two independent sites agree.

  • Honest gaps

    If we can't find them, we say so and show you the next best way in.

Questions

The short answers.

Do we need a lead service?
No. But if you have one, we'll use it. Its projects get researched alongside everything we find.
Can we limit it to the work we do?
Yes. Markets, project types, job size, stage, and whether a GC is already named.
Where does the information come from?
Public records and company websites. Every fact links to its source.
What if you can't find the person?
We tell you, and point you to the next best way in, like the architect or the zoning attorney.
Does anything get sent without us?
No. Every note waits for your review.
