AI-native, not AI-bolted-on

Your agent has the keys. With guardrails.

The first marketing platform built around AI agents, not a CRM with a chatbot bolted on. Agents operate the funnel; you stay in the strategy seat.

Hosted MCP

Connect Claude or Cursor to mcp.funnelfizz.com in one click. ~50 tools to read insights, draft emails, recommend splits, and propose automations.

Drafts, not commits

Every mutation an agent makes is a reviewable draft. One-click revert from your dashboard. Full audit log per workspace. Defensible in a security review.

Per-plan rate caps

Mutations gated per-minute, per-day, and per-month so a runaway agent loop cannot hurt you. Substance over hype, with the audit trail to prove it.

The funnel, finally attributable.

From first impression to paid subscription, in one timeline you can defend in your Monday meeting.

End-to-End Attribution

Social post → site visit → trial → paid → upsell. One timeline. Stripe-native. Built for the freemium and PLG funnels HubSpot was never designed for.

Splits with 8 Conditions

Geography, device, channel, UTM, custom event, A/B variant, Stripe product, Stripe price. Nest them. Stack them. Cohort permutations in the thousands.

Extension Chains

Append Consideration → Trial → Customer past your first sale to model upsells, re-trials, and churn-saves. The lifecycle that actually drives NRR.

Lifecycle email, native

Email reaches people at the exact stage that matters.

Not a list. Not a segment. A specific stage card on a specific cohort. Drafted by your agent. Sent by you, or by an automation step bound to the same card.

Stage + condition targeting (8 split conditions, nested + extension cohorts)
Drag-drop block composer, HTML mode, plain text, or templates
Per-recipient A/B subject testing with auto-winner pick (PRO)
Verified senders + custom domains via Resend
Drip campaigns and stage-entry triggered sends

Automations

Lifecycle on autopilot. Wired to your funnel cards.

Every automation is bound to one specific stage card: main funnel, split track, extension, or nested-extension. No orphan workflows. Every flow lives DRAFT-first; you decide when it goes live.

Triggers

Stage entry: Fires whenever a profile lands on the bound stage.
Stripe trial: Fires on Stripe subscription status → trialing.
Stripe paid: Fires on Stripe subscription status → active.
Stripe canceled: Fires on terminal status: canceled, unpaid, expired.

Steps

Send email: A/B subject testing + tracked.
Wait: Fixed delay before the next step.
Wait until: Hold until a stage entry or event lands.
Conditional split: Branch on profile attributes or events.
Percentage split: Random allocation for in-flow A/B tests.

30-day diagnostic

Strong Awareness, soft Trial→Customer on mobile

Win to keep doing

Awareness up 41% vs prior period; LinkedIn drove 38% of identified visitors.

Critical finding

Trial→Customer on mobile: 14.2% vs 31.8% on desktop. Likely checkout friction.

Quick win, minutes

Add a mobile-cohort split at TRIAL and ship a checkout-help email.

AI Reports · powered by Claude

What's working. What isn't. What to ship next.

Senior-advisor diagnostics across your full funnel. Score 0-100, capped if Stripe or tracking aren't connected. No grade inflation. Wins to double down on, the highest-leverage gaps with evidence and datapoints, quick-wins shippable in minutes, and experiments to run next.

Pro tip: hand the report to your agent. It can read findings, propose splits, draft the emails, and queue the experiments as drafts you ship.

Up and running in an afternoon.

Self-serve. No demo required. No procurement war.

Map the funnel

Default template + cohort splits in under two minutes. The visual canvas is the source of truth. Every email, automation, and report binds to a stage card.

Connect Stripe + tracking

Paste the snippet on your site. Link your Stripe account. Wire in Google Search Console and Resend if you want them. An afternoon, not a quarter.

Hand off to your agent

Install the FunnelFizz MCP at mcp.funnelfizz.com. Claude or Cursor can now read insights, draft emails, recommend splits, and propose automations as drafts you review.

FunnelFizz alongside HubSpot.

You don't have to migrate to evaluate. Plug in alongside, prove value in 14 days, then consolidate when ready. Honest comparison, no contempt for the time you spent learning the legacy stack.

Questions? Answers.

Yes. The hosted MCP at mcp.funnelfizz.com exposes ~50 tools across setup, insights, email drafts, automation drafts, splits, and reports. Connect Claude or Cursor in one click. Every mutation lands as a DRAFT that you review and ship. Never auto-applied.

Visitors get tracked from first touch. When they identify (form, signup) and later convert in Stripe, every step lands on the same profile timeline: channel, UTM, stage, plan, price, all linked. AI Reports surface the wins so you can put a defensible number in your Monday meeting.

No. Plug in alongside. Connect Stripe + your site + email senders, prove value in 14 days, then decide what stays and what consolidates. We respect the time you spent learning HubSpot. We want to show you what is possible next, not guilt-trip you for what you have.

Three layers of guardrail. (1) MCP mutations are DRAFT-only: your agent proposes, you ship. (2) Per-plan rate limits per minute / day / month so a runaway loop cannot hurt you. (3) Every mutation is logged and one-click revertable from your dashboard. Defensible in a security review.

FREE for getting started (3 funnels, basic tracking). HOBBY at $19/mo unlocks splits, email, and AI Reports (3/mo). PRO at $99/mo adds team workspaces, A/B subject testing, custom domains, and 20 reports/mo. Annual billing saves 20% on both paid tiers. No contracts. No procurement war.

Encrypted in transit and at rest. OAuth tokens encrypted with AES-256. We never sell your data. Audit log on every MCP mutation. Workspace-scoped permissions on every API key.
