GTM Systems Builder

I build the GTM systems that turn B2B pipeline into revenue.

Better quality conversations, not more noise. I build the outbound, CRM, scoring, and routing systems that produce them, inside your accounts, on your data.

OPTION ONE

I run it

Fractional GTM Engineer

I build it and keep running it, month to month, inside your team.

You're a good fit if

  • You need someone to build and run the system
  • You want to test the role without the full-time commitment
  • Nobody owns your outbound today, and reps are doing it by hand
From
$4,000 / month
OPTION TWO

You run it

Build Your GTM System

I build it, train your team on it, write it down, and hand over the keys.

You're a good fit if

  • You want a system that delivers results and you run it yourself
  • You have a team to hand it to
  • You want to own the asset, not rent it from an agency
 
$6,000 minimum
OPTION THREE

You run it, I sharpen it

Advisory

No build. You have the people; I make sure they're building the right thing.

You're a good fit if

  • You already have a GTM hire or team
  • You need judgement, not another pair of hands
  • You're choosing tools or moving Clay to Claude Code
From
$1,250 / 5 hours
