AI Growth Engine Retainer

The AI Growth Engine Retainer gives you a fully managed AI marketing infrastructure — content, paid, CRM, SEO, attribution — with monthly deliverables tied to your specific growth targets. We own the system. You own the results.

Pricefrom £4,500 / month
TimelineRolling monthly (3-month minimum)
Ideal forGrowth-stage businesses (£2M–£15M revenue) ready to systematise marketing and compound results.
[ Outcome ]

A complete AI-powered marketing operation delivering measurable results every month.

The AI Growth Engine isn’t a set of tools — it’s an operating system for your marketing function. Every month, your Zinerge team delivers a defined set of outputs across content, paid media, CRM, SEO/GEO, and attribution.

The compounding effect is the point. Month one establishes the baseline. By month six, the system knows your business well enough to surface opportunities your team hasn’t thought of yet.

✓ Who it's for

For businesses that have either graduated from the Launchpad and want to keep building, or are coming to Zinerge at a stage where they need a complete AI marketing operation rather than a single workflow.

Typical clients: DTC e-commerce scaling £2M to £10M, B2B with sales cycles longer than 30 days, SaaS companies building content authority, hospitality and property businesses with ongoing marketing needs.

✗ Who it's not for

Businesses in the first phase of their AI journey — start with the Launchpad. Businesses that need strategic leadership without execution — see the Fractional AI CMO.

[ Comparison ]

vs. the alternatives.

vs. a traditional marketing agency

A traditional agency delivers outputs. The Growth Engine delivers system outputs — content that compounds, paid media that optimises itself, CRM data that improves every month. The compounding effect is the difference.

vs. building an in-house marketing team

A marketing manager + content + paid media specialist costs £120,000–£180,000/year in salaries alone. The Growth Engine is £54,000/year with senior AI expertise across every function — no recruitment risk, no notice period.

[ FAQ ]

Common questions.

What's the minimum commitment?

3 months. AI systems need at least 90 days of data to optimise effectively. We don't take on clients who aren't prepared to give the system enough time to prove itself.

Can I pause if our budget changes?

We offer a pause clause after the first 3 months — up to 60 days pause per 12-month period. Pausing stops delivery but preserves all systems and data.

How is the monthly fee structured?

The management fee is fixed. Paid media ad spend is managed by Zinerge but billed directly to your card — you maintain full visibility and control.

Who works on our account?

You have a named lead strategist who is your primary point of contact and attends every monthly call. Specialist work is handled by senior practitioners within the Zinerge team.

Do we need to have completed the Launchpad?

Not necessarily. If your existing systems are mature enough, we can onboard you directly onto the Growth Engine. The first month always includes an audit.

The best time to systematise your marketing was last year. The second best time is this month.

Book a fit call. We'll review your current marketing stack, biggest growth constraint, and tell you whether the Growth Engine is the right fit — and what it would deliver in your first 90 days.
