The best growth experiment tools for small teams.

Which growth experiment tools are worth a look?

Seven tools and templates, and what each one is best at. We make Theanna, so it's first and labelled as ours. Every tool gets a weak spot too, ours included. We don't list other tools' prices, because they change. Check each site.

• Theanna (we make this one)

  Best for:

  Small teams working toward one company target

  Where it falls short:

  Not an A/B testing tool: it doesn't split traffic on your site

• Growth Method

  Best for:

  B2B marketing teams of 1 to 10 running campaigns

  Where it falls short:

  Built for marketing, not product or engineering experiments

• Effective Experiments

  Best for:

  Formal A/B testing programs at larger companies

  Where it falls short:

  Runs on top of a testing tool like Kameleoon, Optimizely or VWO

• GrowthOrange (formerly UpGrow)

  Best for:

  Smaller growth teams building a library of what they learned

  Where it falls short:

  Results are typed in by hand; Zapier is its only connection

• Notion template

  Best for:

  Starting free, today

  Where it falls short:

  Someone types every number, and nothing checks it

• Airtable template

  Best for:

  Starting free, with more structure than Notion

  Where it falls short:

  Same as Notion: every result is typed in by hand

• An A/B testing tool (GrowthBook, Statsig, PostHog)

  Best for:

  Testing two versions of a page or feature

  Where it falls short:

  Doesn't track outreach, events, partners or pricing tests

Theanna: best for small teams with one target

Theanna is a growth experiment platform for small teams. You set one company target, like $1M ARR by December. You pick up to 3 goals to get there. Then you run experiments under each goal.

Theanna reads every result from the tools you already use: Stripe, Google Analytics, Calendly, HubSpot, Customer.io and more. Every experiment checks in each week, so nobody chases updates. When one works, Theanna uses it to pick the next one, even under a different goal.

It also works inside Claude, ChatGPT, Cursor and any AI tool that supports MCP. Your team can ask what to test and check the numbers without opening a new app.

Where it falls short: it isn't an A/B testing tool. If you need to split traffic between two versions of a page, use one of the A/B tools below next to it. The Team plan starts at $999 a month for up to 3 people.

Growth Method: best for B2B marketing teams

Growth Method is an agentic marketing platform built for B2B marketing teams of 1 to 10 people. Agents help plan, launch and measure marketing campaigns.

Where it falls short for a whole team: it's built for marketing. If product, engineering and marketing all run experiments toward the same number, you'll want one place for all of them. Our side-by-side: theanna.io/theanna-vs-growth-method.

Effective Experiments: best for formal A/B testing programs

Effective Experiments manages large A/B testing programs: research, backlogs, approvals and reporting. It sits on top of a testing tool like Kameleoon, Optimizely or VWO.

Where it falls short for a small team: it's built around website and product A/B tests at bigger companies. Outreach, events, partner and pricing experiments aren't what it's for. Our side-by-side: theanna.io/theanna-vs-effective-experiments.

GrowthOrange (formerly UpGrow): best for a library of learnings

GrowthOrange is the new name for UpGrow. It's an experiment tracker for smaller growth teams: ideas come in through forms, get scored in one view, and every result goes into a searchable library of what the team learned.

Where it falls short: results are entered by hand. Its site names Zapier as the only way to connect other tools, so someone still has to type in the numbers.

Can a Notion or Airtable template work?

Yes, to start. A template is free, everyone already knows how to use it, and you can set one up today. Notion and Airtable both have growth experiment templates ready to copy.

It breaks once more than one person runs experiments. Each person keeps their own sheet, numbers get typed in late or not at all, and nobody can say which test moved the business. A template holds what someone types. It can't check the number for you.

When should you pick an A/B testing tool instead?

Pick an A/B testing tool when the test is two versions of the same page or feature, and you have enough traffic to split. GrowthBook, Statsig and PostHog are built for that. They're strongest when engineers own the test.

They don't track the rest of growth: a cold email sequence, an event, a partner deal or a price change. Many teams use both: an A/B tool for the site, and an experiment tool for everything else.

How do you pick the right one for your team?

1. 01

   Write down your one number

   Revenue, active users or paying customers. If your team can't agree on it, start there, not with a tool.

2. 02

   List what you'll test

   If it's mostly page and feature tests, start with an A/B tool. If it's outreach, events, partners, pricing and product, you need an experiment tool.

3. 03

   Check where the numbers come from

   Pick a tool that reads results from the tools you already use. If people have to type numbers in, they'll stop by week three.

4. 04

   Count who runs experiments

   One marketer can live in a template. Once two or three people run tests, everyone needs to see the same results in one place.

Which growth experiment tools are no longer available?

• Panobi closed in May 2024, according to Growth Method's roundup.
• GrowthHackers Experiments: its product page now redirects to a domain-for-sale listing, and the GrowthHackers site no longer mentions it (checked 9 Nov 2026).
