Build

How a build works, and what it costs.

One system, several, or something entirely your own. You pay for the strategy, the campaigns, and the systems and agents that run them. A dashboard is optional. Prices in EUR, excluding VAT.

Getting started

01 · 20 minutes

A call

Twenty minutes on how growth runs in your company today. If a build is not the right answer, we say so.

Free
02 · Two weeks

Diagnosis and proposal

We map where growth leaks, which work should run as a system, in which tools and in what order. You get the written plan and a fixed quote for the first build.

Paid · credited against a build signed within 30 days
03 · Four to six weeks

Build

The first system is built inside your workspace, on your positioning, your voice and your approval rules. At least two of our experts, growth and engineering, work on it for the duration. Drafts start landing in week one.

Builds from EUR 6,000
04 · When you are ready

Add, or hand over

Later systems reuse the plumbing and the shared memory the first one created, so they cost less. Or stop here: you own everything that was built.

Quoted per system

Bespoke by default

Three shapes a build can take.

Nothing here is a product you install. Each system is designed around how your company already sells, writes and follows up, then built into the tools you open every morning.

One system

Start with the one that leaks most.

Usually acquisition or engagement. Carries the discovery and the plumbing every later system reuses.

From EUR 6,000
Several systems

Build the loop.

Acquisition that knows what content went out. Content that hears what sales calls said. One calendar, one memory, one approval rule.

Quoted per system
Fully custom

Something only your company needs.

A system that does not exist yet, or a surface of its own, like a private dashboard or a Slack or WhatsApp approval flow. Scoped in the diagnosis, quoted as a project.

Quoted per build

Where it lives

Inside the tools you have, or an internal app we build for you.

Prepared work lands where your team already looks: HubSpot, Pipedrive or Attio, Gmail or Outlook, Notion, Slack, LinkedIn and your ad accounts. If you would rather have one place to review and approve everything, we build that too, on your domain, with your data. Yours to keep, hosted where you say.

After the build

Keep it running, or keep it improving.

Optional. Three-month minimum on retainers, then monthly. We take a limited number of retainer clients at a time.

Optimise · Priced to scopeCare plus a weekly review, experiments and tuning with your team.
Managed · Priced to scopeWe operate the systems with your team, including the human side of the gaps that have no owner yet.

Questions

Questions about pricing.

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.
Why a fixed price rather than hourly?
Because you are buying a working system, not our time. Scope is defined by deliverables before we start, so the number does not move. Out-of-scope work, if you want any, is quoted separately in capped blocks.
Is the diagnosis really credited?
Yes. If you sign a build within 30 days, the diagnosis fee comes off the build in full. If you do not, the written plan is yours to run yourself or with anyone else.
How do payments work?
Builds are 50 percent on signing and 50 percent on delivery. Retainers run on a three-month minimum, then monthly. Prices are in EUR, excluding VAT.
Do I need a retainer?
No. Every system is handed over with documentation and a runbook, and keeps running without us. A retainer is for tuning and new work.
