The problem
You shouldn't have
to pay and pray.
Most agencies run the same playbook for every client. The founder pitches you and disappears. Junior staff takes over and you pay month after month hoping something sticks.
You deserve to pay, and actually play. Results you can see, systems that work, and a team that doesn't disappear after the invoice.

How it works
Here's what
actually
happens after
you sign.
No onboarding limbo. No junior hand-offs. The system goes live and stays live.
01 / Discovery map
Intake & Discovery
Week 1We get to know your business properly. Audience, competitors, keywords, brand voice, goals. All of it goes into a config built just for you. Nothing borrowed from the previous client.
Build
Week 2We set up your full marketing system. Content, ad infrastructure, tracking. Everything is live before the first invoice clears. Not 'we'll have it ready in a month.'
Produce
OngoingThe system runs. Blog posts, social content, ad creatives. Published on schedule, every time, without you lifting a finger. You check a dashboard, not a Slack thread.
Optimize
WeeklyNumbers get reviewed weekly. What's working gets more budget and attention. What isn't gets fixed or cut. No waiting for a monthly report to find out what went wrong.
Report & Compound
AlwaysYou get a live dashboard with everything in one place. And every week the system learns: better targeting, better content, better results. It compounds over time.

What clients say
Don't take our
word for it.
“Kyle doesn't think like a typical marketer. He came in, understood the whole problem in about a week, and built systems we're still running today. The way he approaches growth is different to anyone I've worked with.”
Andrew
Founder & VC, Ghost Startup
“Kyle built the entire marketing infrastructure for ApeFX from scratch. Content systems, paid strategy, positioning. All of it. The approach was different to anything I'd seen from an agency because it came from someone who thinks like a founder, not a marketer. Data-first, no fluff, no hand-holding required.”
Claire
Co-Founder, ApeFX
“Kyle gets gaming communities in a way most marketers just don't. He built our presence from scratch and the numbers showed it. Straight shooter. Does exactly what he says.”
Shane
Founder, Bloxflip
Why Fatboy
What makes us
different.
Your data stays yours.
Everything runs on our own infrastructure. Your data never goes near a third-party server. No other agency can say that. We built it this way deliberately.
We optimise for AI search.
ChatGPT, Perplexity, Google AI Overviews. When someone asks an AI for a recommendation in your space, we work to make sure you come up.
The system runs.
Consistent output. No human bottlenecks. No ‘your account manager is on leave’ surprises. The machine keeps going regardless.
Ten clients. That's it.
We cap at 10 clients on purpose. It means your work gets real attention, real strategy, and a founder who actually knows your business inside out.

Why this exists
The gap nobody
was filling.
A decent agency costs $20-50k+ a month and treats you like ticket #47. Template work, no measurable output. Building in-house costs $100-400k in headcount and 12 months you don't have. Series A-B startups are stuck in between.
Fatboy exists to fill that gap. Custom systems, founder-direct attention, and infrastructure that compounds over time. The kind of setup that used to require a full marketing team, engineered to run lean.
I'm a multi-startup founder and operator. I've built from zero in AI, SaaS, fintech, and consumer apps. When you work with Fatboy, you work with me. Not a junior hand-off, not an account manager reading a brief.

FAQ
Questions we get a lot.
It means your marketing system runs on AI models we host ourselves. Content gets written, scheduled, and published automatically. Ads get reviewed and adjusted by AI before they go out. You get the output without the overhead.
Most agencies have 50+ clients and a junior team handling day-to-day. We cap at 10 clients, you work directly with Kyle, and everything runs on custom systems built for your business specifically. The work is different because the setup is different.
Yes. We work remotely with teams everywhere and have run campaigns across multiple countries and time zones. Location never affects how we work or what you pay.
Your data stays on our infrastructure. We run local AI models, so nothing goes through OpenAI, Google, or any third-party AI service. This is one of the main reasons clients choose us.
Month one is setup and launch: intake, config, pipelines live. Month two you'll see content volume and early paid data. By month three you have real numbers to optimize from and a system running on its own.
Quality of work goes down as client volume goes up. 10 is the number where we can still do everything well. It's a constraint we set on purpose, not a capacity issue.
No. Month-to-month on all plans. We'd rather keep clients because the work is good, not because they're locked in.
Usually within a week of signing. First thing is the intake session where we map your setup properly. From there, the pipeline is live within days.
