Experiment tracker, CSV
One row per experiment and 18 columns, with three example rows: one idea, one ready to start, one closed with its learning. Delete the examples and add yours.
One-page experiment doc, Markdown
The same fields for one experiment, split into before and after the test. Paste it into Notion, Google Docs or your repository.
What goes in each column
Every field, and when it becomes required
An experiment does not need every field on day one. An idea needs three. The rest become required at two moments: before the test starts, and when it closes.
Title title
A short name that says the page or channel and the change.
To create it
Idea short_idea
One or two sentences: what you will change.
To create it
Funnel stage funnel
One of Awareness, Acquisition, Activation, Revenue, Retention, Referral.
To create it
Hypothesis hypothesis
If we change X for Y, then Z will move, because of the evidence you have.
To reach Ready
Segment target_segment
Who sees the test: new visitors on mobile, trial users in week one.
To reach Ready
Success metric success_metric
The one number that decides the result, written before the test starts.
To reach Ready
Fail criterion fail_criterion
What result means the idea did not work, so nobody moves the goalposts later.
Optional
Baseline baseline_value
The metric today, with its period and source.
Optional
Start date start_date
YYYY-MM-DD.
To reach Ready
Due date due_date
YYYY-MM-DD: when you will read the result.
To reach Ready
Framework framework
ICE, PIE or RICE.
Optional
Scores scores
One score per letter, from 1 to 10: impact=8; confidence=6; ease=7.
Optional
Status status
Idea, Approved, Ready, Running, Analyzing, Winning, Failed, Inconclusive, Learned or Archived. Empty means Idea.
Optional
Result result
Win, Lose or Neutral, once the test is over.
To close it
What happened actual_result
The measured number against the baseline, the sample and the dates.
To close it
Learning learning_summary
What the team now knows that it did not know before, in one paragraph.
To close it
Next step next_steps
Ship it, iterate, or drop it, and the follow-up test if there is one.
Optional
Evidence evidence_links
Links to the test report, the dashboard or the research, separated by |.
Optional
The two rules
Two checks that keep a tracker honest
Before the test starts
No test reaches Ready without a hypothesis, a segment, a success metric, a start date and a due date. Writing the metric first stops the team from picking, after the fact, the number that happened to go up.
When the test closes
No test closes as Winning, Failed, Inconclusive or Learned without what happened and a written learning. A closed test with an empty learning is a test the team will run again.
This CSV contains no lifecycle validation, and importing it into a spreadsheet or a Notion database does not add those checks: anyone can fill in the status and skip the rest. Hypotize enforces both on the server, for people in the web app and for AI agents connected through MCP.
Worked example
One experiment, filled in to the end
Product page: reviews under the price
- Hypothesis
- If we show reviews next to the price for mobile visitors, add-to-cart will rise, because session recordings show most visitors never scroll to the reviews.
- Segment
- Mobile visitors on product pages
- Success metric
- Add-to-cart rate per session
- Baseline
- 5.4% add-to-cart rate, last 30 days, product analytics
- What happened
- 6.1% against 5.4% for the control over 21 days.
- Learning
- On mobile, proof next to the price matters more than proof lower on the page. Next, test the same placement on the cart page.

With an AI agent
Give the file to your agent
The column names are the field names of the Hypotize import, so the agent needs no mapping: it only converts dates, scores and links, and leaves out the empty cells. Connect Claude, ChatGPT, Grok Bot, Cursor or Codex to Hypotize, attach the CSV and paste the prompt. The agent imports up to 50 rows at a time, and Hypotize checks each row against the two rules: a row marked Ready without a success metric is rejected, and the error names it.
Prompt for your agent
Read the attached growth experiment CSV. Import every row into my Hypotize project with the experiment import tool, keeping each row's status. Convert the dates to ISO timestamps, the scores column to one number per letter and the evidence column to a list of links. Leave out empty optional fields, including result: do not send them as empty text or null. If Hypotize rejects a row, tell me which row and which field is missing, and do not invent values to make it pass.
FAQ
Questions about the template
What should a growth experiment template include?
A title, the idea, the funnel stage, a hypothesis, the segment, one success metric, start and due dates, a priority score, and after the test the result, what happened and the learning. This template has all of them, plus a fail criterion, a baseline, next steps and evidence links.
Is the template free?
Yes. The CSV and the one-page experiment doc download directly from this page, with no account and no email.
Can I use it in Google Sheets, Excel, Notion or Airtable?
Yes. It is a plain CSV: Google Sheets, Excel, Notion and Airtable all import CSV files. The steps for each are on this page, with a link to each vendor's help page.
What does the template not do?
A file cannot enforce its own rules: anyone can mark a test Learned with an empty learning. Hypotize rejects that write on the server, in the web app and over MCP.
How do I move the template into Hypotize?
Connect your AI agent to Hypotize and give it the CSV with the prompt on this page. The column names match the fields of the Hypotize import: the agent only converts dates, scores and links to the import format, leaves out the empty cells, and imports up to 50 rows at a time. If one row breaks a rule, the whole batch is rolled back and the error names that row.
