For B2B companies
The sales & marketing team you can't hire

We are your
sales & marketing
department.

Every B2B company needs a team that can build the outbound system, own content, manage web operations, and run the full pipeline. That team is expensive, slow to hire, and hard to keep. We already are one.

The problem

The person who can do
all of this with AI barely
exists. Everyone is trying
to hire them.

"Almost every founder I speak with is trying to hire one person who can map the ICP (Ideal Client Profile), build the outbound system, own content, and run the full pipeline — solo. Many are calling this the GTM (Go To Market) Engineer. It's becoming one of the highest-paid roles in tech." — Chris Pisarski, Crustdata (YC F24)

The "GTM (Go To Market) Engineer"

Map the ICP (Ideal Client Profile). Build outbound. Own content. Run the pipeline. Analyze calls. Own the CRM. This role exists — and salaries doubled in 3 years. You'll compete with 30 other companies for each candidate.

One person. Eight functions. Almost no one can do it.

The agency stack

Traditional agencies specialize. One for outbound, one for content, one for web. You coordinate between them, manage three retainers, and still need someone internally to own the strategy.

$5K–15K per agency · You still need a lead to run them

The tool stack

Clay, Apollo, Jasper, Webflow — the tools exist. Someone still needs to configure, connect, and run them. And you still pay for every seat, on top of the salaries.

Clay — $149–$800/mo for enrichment and prospecting data
Apollo or similar — $99–$499/mo for contact databases
Jasper or similar — $49–$125/mo for AI content drafting
Webflow or similar — $23–$235/mo for web management
Pitchbox or similar — $195–$500/mo for PR outreach

What you're probably doing now
You buy tools.
You still do the work.
You pay for Clay, Apollo, Jasper, Webflow. You hire someone to run them. You manage that person. Six months later — the tools are live, but the pipeline isn't.
The thesis
Most companies are paying for five tools, a contractor to run them, and still wondering why the pipeline isn't moving. The problem isn't the tools — it's that tools require operators. Departments deliver results.

How it works

Simple for you.
Invisible to your clients.

We don't ask you to learn a platform or manage a team. You describe what you need, and the system runs.

1

Onboard

One session. We map your ideal clients, goals, competitors, and content strategy. The system configures itself around your business.

2

System runs

Outbound starts prospecting. The content engine publishes. Web operations monitors. No tasks land in your inbox. It runs 24/7.

3

You receive results

Pipeline, published content, backlinks earned, and a managed web presence. Not dashboards — finished work, delivered.

Proof
A copilot sells the tool.
An autopilot sells the work.

Building the team to do this in-house costs over $200K a year in salaries alone — before tools, management overhead, or a 90-day ramp where they produce nothing. We run the whole system for a fraction of that.

Salary ranges based on US market data (Glassdoor, LinkedIn Salary, Bureau of Labor Statistics, 2025). Actual cost varies by location and seniority.
We went through serious SaaS sprawl — tool after tool, subscription after subscription, and still no pipeline. With Fullstack GTM I stopped paying for software and started paying for results. That shift changed everything.

Founder · Fullstack GTM

I built Fullstack GTM because I was my own first client. Running outreach, content, and web operations with a two-person team, I started automating everything with Cursor and Claude — and the systems worked better than the people had. Seven months later, those systems run for paying clients.
