Engines & Tiers · choosing the right level for your business

• Pipeline Engine · £5,000 / yr · entry tier · "Vetted Supplier · Foundation". Buyer- led demand flow + ecosystem membership.
• Revenue Engine · £10,000 / yr · "Growth Supplier · Enhanced Exposure". Adds sales motion documentation, pricing workshops, cohort margin reviews.
• Visibility Engine · £25,000 / yr · "Brand Surface Tier". Adds multi-event presence, stand booking, speaker slots, sponsored campaigns.
• Authority Engine · £50,000 / yr+ · "Category Leader Tier". Adds category-defining content, awards positioning, partner introductions at scale.

All four are annual memberships. Tiers are cumulative · Revenue includes Pipeline's deliverables, Visibility includes Revenue's, and so on.

Open /engines/compare · the canonical side-by-side. You can also jump in from the pillar pages · The Roadmap, The Bridge, The Ecosystem, Authority · each one is a deep-dive on its associated engine.

The page has four sections:

1. Tier cards · 4 columns side-by-side at the top. Each card shows the tier name, price, "right for" / "not right for" copy, and the top three emotional benefits.
2. Deliverable matrix · the Schedule 4 list with ticks showing which tier includes which deliverable. This is the contractual picture · "what am I actually paying for".
3. Benefits deep-dive · click any tier card to expand into its full benefits list · 12-15 items per tier with proof copy.
4. CTAs · book a tier conversation or apply to the wait list.

Three questions answer it cleanly:

1. What's your average deal size? · the ROI math works at any tier if 1-2 wins covers the membership. Below £15k average deal size, start at Pipeline · above £100k average, consider Revenue or higher.
2. How is your current sales motion? · documented + repeatable → Pipeline is enough. Founder-dependent + ad-hoc → Revenue Engine includes the workshops that fix this.
3. Are you visible already? · yes (events, speaking, content) → focus on Pipeline / Revenue for demand flow. No → Visibility tier specifically targets brand surface.

Most suppliers start at Pipeline and upgrade once they've closed 3-5 buyers through the platform. The ROI signal is clear by then.

Buyers don't pay for engine membership · the engines are for suppliers. But understanding the tier ladder helps you read supplier responses · a Pipeline-tier supplier responds differently from an Authority-tier one, and the tier badge on the supplier card tells you which.

• Pipeline-tier suppliers · hungrier, fast to respond, often the right fit for sub-£50k engagements.
• Revenue-tier suppliers · more documented sales process, better at scoping, sweet spot for £25-150k engagements.
• Visibility-tier suppliers · brand-conscious, longer responses, fit for £100k+ engagements where positioning matters.
• Authority-tier suppliers · category leaders. Premium pricing. Right for strategic engagements where the supplier's reputation is part of what you're buying.

The "Schedule 4" matrix is the contractual core of every supplier engagement. Each deliverable has a code (e.g. "1a", "3f") and a tier in which it first appears. Read it like this:

• Code 1a · Pipeline · everyone gets this deliverable from Pipeline tier up.
• Code 4c · Visibility · only Visibility and Authority tiers get this.
• Code 6a · Authority only · exclusive to the top tier.

When you upgrade tier, your contract is amended with the new deliverable list. The deliverable matrix is the single source of truth · marketing copy elsewhere is translation, the matrix is the contract.

• Upgrading · email your account team or book a tier conversation via /contact. We pro-rate the difference against your remaining membership period · you're not double-paying.
• Downgrading mid-contract · always an operations decision, not a one-click action. Talk to your account team if you're considering it. We'd rather understand the underlying concern than rubber-stamp the change.
• Cancelling at renewal · standard 30-day notice before your renewal date. No penalty.

If you've run the GrowthLens diagnostic, the Premium Recommendations stage (Stage 5) maps your weakest categories to the engine that best addresses them · essentially a personalised tier recommendation based on your actual scores. Run the diagnostic before a tier conversation if you can · it makes the conversation shorter and the decision sharper.
