Growth engineering studio · AI growth automation

We build systems,
not campaigns.

Growth that keeps running when you can't. Not another tool. A teammate that uses the best of them.

Why a system

Campaigns end. A system compounds.

Small teams do not have a growth problem. They have a capacity problem. We find the gaps that cost you most and build the function that fills them, around how you already work.

What a growth engineering studio doesWhat we automate, and what we never do

01

An in-house growth engineer

Senior judgment on what should run without a person, then the build. Designed around how you work, not a template.

02

Runs when you can't

The daily work a full team would do, prepared before you start. You approve; it does the rest.

03

Compounds, and stays

Each week's results feed the next. System, data and playbook are yours, engagement or not.

FounderGrowthOS

A growth engineer on your side, and a system that stays.

Senior judgment on what should run without a person, then the build to make it so. Designed around how your company already sells, writes and follows up. In your tools, on your data, owned by you.

CostA fixed build, then a capped retainer if you want one. A fraction of a hire, and it does not leave.
Time to valueDiagnosis in two weeks. Prepared work landing in week one of the build.
FitBespoke to your process, your voice and your stack. Not a template with your logo on it.
ControlPrepares, never sends. A named person approves. Every send has a receipt.
How a build works

Who builds it

A team of growth and engineering experts, building with the best tools there are.

Anyone can wire up an automation with an AI agent in an afternoon. Keeping it good takes judgment about what should run, engineering that holds up, and the right data underneath. Every build has at least two experts on it from the first day to handover.

Growth

Judgment first

Led by Amy Wilkinson, ex-CMO. The rules your system follows are decisions an operator with a track record made first, then wrote down.

Engineering

Built to hold up

Approval enforced by the tools themselves, records the next run reads, and keys that stay in your accounts.

Tooling

The best layer for each job

We pick the strongest tool for every step and swap in better ones as they ship, so your team never has to keep up with the market.

Tools we build with

Chosen per build. Your accounts, your keys.

Logos belong to their owners. No partnership implied.

Growth diagnostic

Where growth is stuck, which buyers to go after first, and the systems I'd build with the wiring, the accounts and the core processes. The map, whether or not we build together.

Included: the diagnosis and the system proposal, in writing, yours to keep.

  • Where growth is stuck, and why
  • The first buyers to go after, and the route in
  • The systems, with wiring, accounts and processes

Engine build

One engine, built inside the tools you already use and handed to your operator. Acquisition is usually first. Content, social, SEO, ads and PR follow on the same system, so what one engine learns reaches the next.

Included: at least two of our experts, growth and engineering, working on it for the duration of the build.

  • Four to six weeks: two to four to build, two to hand over
  • Two revision rounds, scope defined by deliverables
  • 50 percent on signing, 50 percent on delivery
  • Nothing sends without your approval. Everything lives in your accounts

Ongoing

After handover, if you want us to stay. Care keeps it running. Optimise keeps it improving. Managed means we run the engines with you, including the human side of the gaps that have no owner yet.

Included: a named tier, a response time, and the same team that built it.

  • Care: troubleshooting, updates and upgrades
  • Optimise: Care plus a weekly review, experiments and tuning
  • Managed: we run it with you
  • Three-month minimum, then monthly

About

A studio, not an agency. One senior operator, a small bench, systems that outlast the engagement.

FounderGrowthOS is led by Amy Wilkinson, an ex-CMO whose work has helped companies scale to $400B in transaction volume and $500M valuations. The method was built on her own companies first.

The work after the buildWhy so many founders stop using the AI systems they built, and the three things I'd do if you're building your own.Testing Jev: 10 growth jobs I’d hand to a model that only makes decisionsI tested Jev on two small pieces of growth work this weekend. It went well, and it barely scratched the surface. Here are the ten builds I think...What is growth engineering?What the job actually involves once AI is doing the work, and the layer underneath that decides whether it keeps working.

Questions

What founders ask before the call.

What does FounderGrowthOS do?
We are a growth engineering studio. We design and build the systems that keep growth running when the founder can't: finding the right companies, drafting outreach and content in your voice, following up, and learning from what worked. They are built in your tools, approved by your team, and yours to keep.
What is a growth engineering studio?
A small, senior team that builds growth systems for other companies and hands them over. You get one senior operator and a bench of growth and engineering people for the build, then a system your team runs. More on growth engineering.
How is this different from an agency or a hire?
An agency runs campaigns for as long as you pay, and the work stops when the invoice does. A hire takes months to ramp and leaves with the knowledge. We build the function once, in your accounts, and it keeps running after we leave.
Does anything go out without my approval?
No. The system prepares the work; a named person on your team approves and sends it. Campaigns land paused until someone sets a budget, and every send is logged with who approved it.
Which tools does it work with?
The ones you already use: HubSpot, Pipedrive or Attio, Gmail or Outlook, Notion or Google Docs, Slack, LinkedIn and your ad accounts. Nothing to migrate.
Is FounderGrowthOS a software product?
No. You pay for the strategy, the campaigns, and the systems and agents we build around how your team works. They can run entirely inside your own tools, or come with a private workspace like our sample build. Either way, you own it.
How long does a build take?
A first system takes four to six weeks, and prepared work starts landing in the first week of the build. It starts with a free 20-minute call and a written diagnosis.
What does it cost?
Builds start from EUR 6,000. Each one is quoted in writing after a paid diagnosis, which is credited in full against a build signed within 30 days. Retainers are optional. Full pricing.
Who owns what you build?
You do. Code, prompts, data and playbooks are yours from day one, running in your accounts. The engagement can end; the system does not.
Do you work with companies outside the Netherlands?
Yes. We are based in Amsterdam and work remotely with teams across Europe, the UK and the US.
