The Platform

Five pillars. One learning system.

Experiments on every surface. Messaging that learns. Mobile attribution. A partner network. A living belief graph. Five pillars on one engine, and every pillar makes the next one smarter.

Every pillar feeds the next. See the loop.

How It Works

The scientific method, built into your growth stack.

Observe what happens. Form a hypothesis. Test it. Learn from the result. Repeat. Apex automates this cycle and compounds your team's intelligence over time.

Choose your depth. Same system, three levels of detail.

You describe what to test

Tell Apex what you want to try. It writes the experiment into your code, deploys it through your pipeline, and measures real business outcomes — not just clicks.

It learns from the result

Every experiment teaches the system. It remembers what worked, what didn’t, and updates everything it knows — automatically.

It tells you what to do next

Based on everything your team has ever learned, the system recommends the highest-impact action. Your 10th experiment is smarter than your 1st.

Each cycle makes the next one better. Knowledge compounds.

Ecosystem

Signal in. Decisions out.

Apex reads from the tools you already use and acts through built-in execution capabilities. Your stack stays. Apex makes it smarter.

Built for Growth Teams

You know these problems.

Every growth team fights the same battles: disconnected signals, decisions based on intuition, and intelligence that evaporates between campaigns. Apex solves them regardless of your vertical.

Whether sales-led, product-led, or hybrid — close the loop from spend to revenue.

You can’t connect ad spend to closed revenue

$0
reconciliation needed

Your analytics shows clicks. Your CRM shows deals. Nobody connects them. CAC and payback period are educated guesses.

Apex maps every event to channel spend and pipeline value. CAC and payback are always current.

Your experiments optimize for vanity metrics

Revenue
not clicks

A $50K enterprise demo and a free trial sign-up are not the same. Your tests can’t tell the difference.

Experiments scored by real business value per dollar. Pipeline, not pageviews.

Your team learns something every week — and loses it by next quarter

10×
faster time-to-insight

Insights live in dashboards nobody re-reads, experiments nobody references, and tribal knowledge that leaves when people do.

Apex turns every signal into institutional memory. The loop compounds — so the 50th decision is dramatically better than the first.

Cost per weighted pipeline dollar

Same platform. Different verticals. The scientific method works everywhere. Your integrations, metrics, and experiments adapt to your business, but the intelligence loop stays the same.

Three Interfaces

Three ways to build intelligence.

Connect your AI agent via MCP for persistent intelligence. Drop in a script tag for zero-code experiments. Or pipe data from your existing stack through native integrations.

MCP Server
Your AI agent connects to Apex's belief graph, prediction calibration, and experiment engine. Every session starts from everything your team has ever learned.

"apex": {

"command": "npx",

"args": ["@apex-inc/mcp-server"]

Beliefs & predictions persist across sessions
AI suggests what to test next
Experiments ship as real code
Calibration tracks prediction accuracy
Script Tag
One line of HTML. Instant text experiments without touching your codebase. Perfect for marketers and non-technical teams.

The Data Flywheel

Every user makes the system smarter for every other user.

Apex aggregates anonymized patterns across all organizations: scoring configurations, experiment outcomes, model drift signals. The result is better default templates, industry benchmarks, and AI recommendations that improve with scale. It is the same network effect that made Stripe's fraud detection and Shopify's conversion benchmarks defensible.

Templates

Default scoring models improve as more companies across verticals contribute data

Benchmarks

Compare your weighted performance against similar companies in your vertical

Recommendations

AI suggestions get better as the system learns what works across industries
