Hypotize vs Growth Method

Growth Method runs B2B marketing campaigns with its own AI agents, and it also opens an MCP server to Claude, ChatGPT, and Cursor. Hypotize has no AI of its own: it is the record and the rules for the agent you already use, with your scoring framework, your team's votes, and stricter checks on when a test may start or close. A team of 3 pays $39/month in Hypotize, against $450/month plus AI usage on Growth Method's Standard plan.

Built for AI agents first

The agent-native Growth OS

Hypotize gives your AI agent the full stack of a growth hacker: the method, the tools to apply it, and rules it cannot bend. Most experiment tools are trackers designed for people clicking through a web app, and some now add AI inside that app. Hypotize starts from the other side: it is a growth-experiment framework your AI agent runs. Claude, ChatGPT, Grok Bot, Cursor, Codex, or any MCP client finds what the team already tested, adds and scores ideas, moves tests through their stages, and records outcomes and learnings, inside the conversation you are already having.

Framework
The method: hypothesis-first ideas, ICE, PIE, RICE, or your own scoring, enforced stages, and a measured result with a written learning at the end of every test.
MCP server
21 tools your agent uses to read and update the record.
Skills
Three skills that teach the agent the method before it acts: running experiments, the weekly review, and importing an existing backlog.
Plugin
One install for Claude Code and Codex that brings the MCP server and the skills together.
App
The board, backlog, and learnings your team works in, on the same record as the agent.

The agent follows the same rules as your team, and the server enforces them: no skipped stage, no test closed without a measured result and a written learning. It never touches billing or members, and it deletes only if you grant that scope at connection.

What Growth Method documents

Growth Method documents an MCP server for Claude, ChatGPT, Cursor, and VS Code: an outside agent can list, create, update, and archive campaigns, and load the team's skills. The difference is where the AI lives. Growth Method runs its own assistant and agents, with AI usage billed at cost; Hypotize runs no model and works through the agent you already pay for.

Example conversation with a connected agent

  1. You

    The checkout test has run its two weeks. Close it.

  2. Your AI agent

    hypotize_experiment_transition

    Hypotize refused to close it: a test needs a measured result and a written learning first. I'm pulling the numbers from your analytics.

  3. Your AI agent

    your analytics connector

    Control converted at 3.1%, the one-page checkout at 3.6%, over 14 days and about 9,800 sessions per variant.

  4. Your AI agent

    hypotize_experiment_record_outcome

    Recorded the result, the evidence, and the learning, then closed the test as a win. Next time anyone on the team asks about checkout, this result comes back with its numbers.

What the other product is

A real alternative with a different emphasis

Growth Method describes itself as “AI agents that run your marketing campaigns”: plan, launch, and analyse campaigns from live data against one goal. Its AI scores every idea, plans and launches campaigns through 50+ marketing integrations, and analyses the results.

Its stated audience is B2B marketing teams on a modern tech stack that move fast and are serious about AI.

A direct alternative with a different centre: both keep a backlog, a scored pipeline, results, and an MCP server. Growth Method puts its own AI at the centre of campaign execution; Hypotize puts your agent at the centre of the experiment record, for any kind of test.

Side by side

Where each one is stronger

Rows about working with an AI agent come first, because that is what Hypotize is built for. Every Growth Method cell comes from its official pages, reviewed on 19 October 2026 and linked in place. Where Growth Method is stronger, the cell says so.

Working with an AI agent

Your AI agent works in the record

Hypotize
Yes, through MCP. Claude, ChatGPT, Grok Bot, Cursor, Codex, and other MCP clients read the backlog and the learnings and update the record with 21 tools.
Growth Method
Yes, through MCP. Claude, ChatGPT, Cursor, and VS Code can list, create, update, extend, and archive campaigns and comment on them; every write asks for confirmation. Rate limit of 30 requests per minute.
Documented
Growth Method MCP server

Rules the agent cannot break

Hypotize
Enforced by the server, for people and agents alike. A test cannot start without a hypothesis, a success metric, a segment, and dates, and cannot close without a result and a written learning that match its outcome.
Growth Method
Stages move by hand. A campaign can't be saved as Complete until its Test result is filled in; whether the MCP tools apply the same check, and whether anything is required before going Live, is not documented.

Shared memory for people and agents

Hypotize
Every person and every connected agent reads the same record of past tests, evidence, and learnings before proposing the next one, so nobody reruns a test that already lost.
Growth Method
An outside agent can list campaigns with their results, metrics, and comments, and look for similar campaigns. Learnings are written inside each campaign's results; a separate learnings library is not documented.

Skills and plugin for your agent

Hypotize
Three skills teach the agent the method before it acts, and one plugin installs them with the MCP server in Claude Code and Codex.
Growth Method
Skills your team writes load into outside agents through MCP, and Claude Code gets them as slash commands; built-in skills cover the campaign workflows. A plugin is not documented.

Built-in AI

Hypotize
None, by design. The agent you already use does the work, so Hypotize adds no AI bill and your record goes to no model you did not choose.
Growth Method
Stronger here if you want AI inside the tool: an assistant and custom agents plan, launch, and analyse campaigns and score every idea. AI usage is billed separately at cost.

Bringing your backlog in

Hypotize
Self-serve: your agent imports up to 50 experiments per call from any tracker it can read, and CSV export takes them back out.

Migrations are run by the Growth Method team; there is no self-serve import in the app. Export is not documented on the reviewed pages.

Decision guide

Who should choose each product

Growth Method homeGrowth Method pricingGrowth Method recording results

Who should choose Hypotize

Choose Hypotize if the agent you already use should run your experiments, not a second AI you pay for. It keeps any kind of test, from ads to pricing, scores it in your framework with your team's votes, and will not start a test without a hypothesis and a metric or close it without a result and a learning. A team of 3 pays $39/month.

Method and sources

How this page was written

Reviewed 19 October 2026. This comparison uses only the official public pages listed below and Hypotize's public product references. No Growth Method account was created or inspected. A missing statement is marked “Not verified”, never converted into a negative claim; “Declared absent” is used only when the vendor explicitly describes something as unavailable or forthcoming. No score, star, or universal winner is assigned.

What “agent-native” means: Hypotize is an operating system for the growth-experiment programme (ideas, priority, stages, outcomes, learnings) built from the start for an outside AI agent: a framework the agent you already use runs through MCP, skills, and a plugin, under rules the server enforces, with no AI of its own. Experimentation platforms that run the tests themselves, such as GrowthBook, Statsig, and Optimizely, offer MCP servers for feature flags and A/B test setup. Hypotize does not run tests: it runs the programme around them, so it works alongside those platforms.
