What we believe
01
Marketing fundamentals don't change.
Whether your team is people, agents, or both, you still need a goal, a strategy, and a system to learn what works.
02
Marketers need to think like engineers.
Hypothesise, launch, measure, iterate. The marketers who adopt the engineer's mindset will win.
03
The future belongs to generalist marketers.
AI is collapsing specialist roles. A small team of generalists can drive more impact than teams many times their size.

06 / FAQ
Frequently asked questions
- How is this different from using Claude, ChatGPT, or Copilot?
- General AI tools give you a blank chat box. Growth Method is purpose-built for marketing: pre-built integrations for GA4, PostHog, Google Ads and many more, a structured create-plan-launch-analyse workflow, and security handled for you. And you're never locked into a single provider, switch in seconds as the market moves.
- What can the AI agents actually do, and will they act without my approval?
- They draft, plan, score, and can launch campaigns for you, on your schedule and within limits you set. Autonomous action only happens when you explicitly allow it. Otherwise agents stop and hand back to a human when a step needs one.
- Is my data secure?
- Yes. The credentials for your connected tools are encrypted with AES-256 at the application layer (unreadable even with direct database access), and your data is isolated to your team and never used to train any model, by us or by the AI providers we route to. Every action an AI agent takes is logged, so you always have a record of what happened. Full details are on our security page.
- How much does it cost?
- £100 per user per month. AI usage is passed through at cost with no markup, and early access includes complimentary reasonable usage.
