In their words.

I had my fingers burned 4 times before I started working with Charlie. In an era where everyone sounds like they know what they are doing using AI, Charlie actually does know what he is doing. If you want to build an outbound infrastructure that works, then do not even think twice. The only reason I could give for not using him is that I would want him all for myself.

Two ways to run with what we build.

Build and handover

You keep everything. No lock-in, no rented infrastructure.

We build the system inside your stack. You get the documentation, the SOPs, the Loom walkthroughs, and your team trained to run it.

Build and run

A monthly retainer. Same build, different ending.

We keep the system running: monitoring, optimising, iterating, reporting. You stay on the work you're best at.

The choice doesn't have to be made on day one. Most clients pick toward the end of the build, once they know whether they'll have someone internal to take it on.

Tools we have worked with.

If you already use some of these, great, we'll plug straight in. If you use or want to use different tools, no problem, we are flexible.

Questions, answered.

01

Do you build campaigns or systems?

Systems, not one-off campaigns. We build real infrastructure: outbound engines, CRM architecture, signal routing and reporting. It keeps working after the engagement ends.

02

Who is behind Groundswell?

Groundswell is led by founder Charlie Brown, who came up through CRM consulting, integrations, and outbound before building full GTM systems. You work with Charlie directly. No account managers, no junior hand-offs.

03

How long does a build take?

Discovery and ICP take the first two weeks. The build and a 30-day inbox warm-up run through week four. The first segment goes live in month two, then we iterate and scale. Allow 30 to 90 days after launch before the system is boringly reliable.

04

Can you name your clients?

One, with written consent: Deligatr. Two more case studies are with their clients for sign-off. Until a client agrees, a descriptor stands in and the numbers stay exactly as counted. We never invent a name, a logo or a quote.

Thirty minutes, no pitch.

Tell us where leads are falling through. You leave with a view of what a system would look like inside your stack, and a straight answer on whether we should build it.
