Human first, enhanced with AI.
We’re Groundswell, a GTM engineering practice. We build GTM systems for established B2B teams, bringing your sales and marketing together in one setup you own outright.
Our story
Groundswell was founded by Charlie Brown, who spent years in B2B sales and consulting before he started building GTM systems.
We believe companies should own their go-to-market end to end, not outsource to agencies that will never know you like you do.
What we believe
Human first AI systems. AI won’t replace everyone in sales and marketing, just those not using it.
AI should do the first touch and repeatable manual tasks: finding the right accounts, writing the first emails and running research.
Once someone engages, a real person takes over. Humans stay in the loop, because trust is what closes deals.
How we work
Every build starts with how you sell today. We map how your sales and marketing work now, and how you want them to work, before anything gets built. Then we build inside your tools, train your team as we go and hand everything over.
Five things hold true whatever you choose to build with us.
01
You own it
You own it
Everything we build lives in your accounts, and it stays yours.
Domains, data, workflows, skills and documentation are set up in your name from day one.
02
Human first
Human first
AI handles the first touch, and a real person takes over the moment someone replies.
Every reply, call and close is handled by a person, because trust is what closes deals.
03
Bespoke
Bespoke
We start with how you sell today and build around your business.
Everything runs on your context: your ICP, your offer, your objections and how your deals actually close.
04
Only what you need
Only what you need
You choose what gets built, so everything we hand over gets used.
Foundation goes into every build, and you pick the rest to fit how you sell.
05
It grows with you
It grows with you
The system learns more about your business the longer it runs.
Claude is set up on your business, and every campaign, call and closed deal adds to what it knows.
