Over the last few years we have reviewed the five tools that defined the growth experiment management category, in depth: TrueNorth, Effective Experiments, GrowthHackers Experiments, UpGrow and Panobi. This page assembles those reviews into one ranked list, with an honest verdict on who each tool actually suits.
One thing an individual review cannot show you is the pattern across the category, and the pattern is brutal. Of the tools below, one shut down entirely, one has been renamed four times, and one is a solo side project built on a no-code platform. The ideas behind these tools are sound. The businesses behind them have been fragile. That belongs in your buying decision as much as any feature list, so we cover it too.
Details and pricing come from our full reviews, linked throughout. Each states when its information was checked, and each is worth reading before you shortlist.

What is a growth experiment management tool?
A growth experiment management tool gives a growth team one place to run its process: capture ideas in a backlog, score them with a prioritisation framework, move the best ones through workflow stages, record results and learnings, and report progress against your goal.
The testing itself happens elsewhere, in your ad platforms, website, email tool and product. What these tools manage is the process around the work: which ideas are worth running, what happened when you ran them, and what the team learned. Without one, that knowledge lives in spreadsheets and leaves when people do.
How we ranked these tools
Six tests, drawn from the things that made these tools genuinely useful in practice and the things that made teams abandon them:
- Goal-first, not activity-first. Does the tool start from your goal and work backwards, or is it a fancy list of tasks? Ranking ideas requires one criterion to rank against.
- Prioritisation that gets used. Scoring frameworks like ICE and RICE only help if the tool makes scoring fast enough that the team keeps doing it.
- Learnings that outlive the campaign. Results and insights should be captured in a structured way, searchable later, not buried in a done column.
- Connection to real data. Integrations that pull results in automatically beat copy-paste screenshots. A tool that cannot see your metrics is a diary, not a system.
- Fit for lean teams. Most marketing teams are small. A tool that assumes a dedicated program manager will not survive contact with a team of three.
- Vendor durability. This category has churned badly. A tool holds your team’s institutional memory, so the vendor’s own health is a feature.

The best growth experiment management tools, ranked
1. Growth Method: best overall for lean B2B marketing teams
Growth Method is the platform we build, and it takes the top slot because it does what every tool below promised, without the manual overhead that made teams quit those tools. The trackers in this list all rely on a human to enter ideas, score them, chase results and write up learnings. Growth Method uses agents to do that work: it analyses your strategy against live marketing data, generates and prioritises campaign ideas against your goal, and measures what moved the number after launch.
Integrations with Google Analytics, Google Ads, Search Console, PostHog and Amplitude are one-click, so results arrive on their own rather than by copy and paste. Pricing is £100 per user per month with API costs passed through at cost.
Best for: B2B teams of 1 to 10 marketers who want the process these tools promised, run largely for them. It is not an enterprise CRO programme manager and does not try to be; if that is your need, Effective Experiments below is the better fit.

2. TrueNorth: best for goal-first campaign planning
TrueNorth, built by Marcus Taylor’s Venture Harbour studio, gets the fundamentals right: start with your goal, project the growth curve, and plan every campaign against it. Our full TrueNorth review rated its design and user experience the best of the classic trackers, and its pricing is low-cost and simple with no hidden limits.
The caveats are structural. TrueNorth shines where attribution is direct and spend is precise, which means paid channels in high-volume SaaS and PLG businesses. Activities with longer horizons, such as SEO, fit awkwardly, and there is no specific process for capturing and sharing learnings. It rewards teams that already have campaign and data maturity rather than building it for them.
Best for: SaaS and product-led teams with clean attribution who want their whole plan measured against one goal. See also our direct TrueNorth vs Growth Method comparison.
3. Effective Experiments: best for enterprise CRO programmes
Effective Experiments, founded by Manuel Da Costa in Manchester, is the enterprise option: an “Experimentation Ops” platform trusted by Cisco, Sage and GSK. Our full Effective Experiments review covers the whole workflow, from a research repository and prioritised idea backlog through automated Gantt-chart roadmaps to programme-health reporting that replaces experiment PowerPoints.
Its integrations tell you who it is for: Optimizely, VWO, Google Analytics and Jira. This is a tool for dedicated CRO and experimentation teams running formal A/B testing programmes across departments. For a small growth marketing team it is overwhelming, and much of its value assumes a partner testing platform sits underneath it.
Best for: enterprise experimentation and CRO programmes that need governance, cross-functional workflow and stakeholder reporting. Pricing ran from £100 per month at the time of our review.
4. GrowthHackers Experiments: best for the classic high-tempo testing playbook
GrowthHackers Experiments is the tool that defined the category, built around the canonical loop: ideate, prioritise, test, analyse, systematise. Our full GrowthHackers Experiments review covers its North Star Metric and objectives model, AARRR growth levers, and prioritisation via ICE, PIE or a fully custom framework, plus integrations with Slack, Jira, Mixpanel, Amplitude and Airtable.
Two cautions. It is expensive compared with the rest of the list and best suited to larger, well-established growth teams doing cross-functional work with engineering. And the product has been renamed four times (Canvas, Projects, Northstar, Experiments), evidence that even the category’s pioneer has struggled to find its footing.
Best for: established growth teams that want the textbook high-tempo testing process enforced in software. See our GrowthHackers vs Growth Method comparison for how it stacks up directly.
5. UpGrow: best for small teams on a budget
UpGrow is the simplest and cheapest tool on the list, built by Dutch growth coach Ward van Gasteren. Our full UpGrow review found a nicely designed product with a smooth onboarding flow, customisable ICE-based scoring, strong tagging and filtering, and structured capture of results and learnings by insight type.
Ward is clear about the gap it was built to fill:
Upgrow is developed based on the past decade of consulting high-growth companies and optimizing their processes. I made this tool as there was no easy-to-use, affordable tool like this for (smaller) growth teams to really take their growth process serious.
Ward van Gasteren, founder of UpGrow
The trade-offs match the price. There are no integrations, so every result is entered by hand. The product is built on the Bubble no-code platform, we hit early bugs in testing, and nothing enforces best practice, so discipline stays on you.
Best for: small growth teams that can live without data integrations and want an affordable, tidy home for ideas, scores and learnings. Pricing started at €29 per month at the time of our review.
6. Panobi: the best product the category lost
Panobi ranks last only because you can no longer buy it. Founded by Merci Grace, former Head of Growth at Slack, it raised around $10 million and built some of the smartest design in the category: a timeline that showed campaigns and metrics side by side, RICE scoring, data-warehouse integrations and AI-written weekly reports. Our full Panobi review captured it in detail before the company closed in May 2024.
I’m sorry to say that we’re closing down Panobi. Early stage startups are high risk bets, and we lost this one. 💔 💜
Merci Victoria Grace, co-founder of Panobi
We keep it on the list because its ideas are worth stealing and because it is the clearest evidence for our sixth ranking criterion: the tool holding your team’s institutional memory needs a durable business behind it.
What the churn tells you
Line the five classic tools up. Panobi is gone despite a Slack pedigree and $10 million raised. GrowthHackers has cycled through four names. UpGrow is one consultant’s side project. These were thoughtful products built by people who understood growth, and the market still would not sustain them as standalone trackers.
Our read: a tool that only manages the process, while humans do all the entering, scoring, chasing and writing up, adds overhead that busy teams eventually refuse to pay. The ideas won (goal-first planning, a scored backlog, captured learnings are now standard practice) but the trackers lost. The teams that stuck with the process either had someone whose job was running it, which is the enterprise story Effective Experiments serves, or they moved to software that does the process work itself, which is the agentic platform story.
How to choose
- You are a lean B2B marketing team (1 to 10 people). Start with Growth Method. You get the goal-first process with the manual overhead done by agents rather than by you.
- You run a formal enterprise experimentation programme. Effective Experiments is the serious option, especially if Optimizely or VWO already sits in your stack.
- You are a SaaS or PLG team with clean attribution. TrueNorth’s goal-first planning is a strong fit, provided your channels are directly measurable.
- You want the textbook high-tempo process and have the team to run it. GrowthHackers Experiments, if the budget stretches.
- You just need a cheap, tidy backlog. UpGrow, eyes open about the lack of integrations.
Whichever way you lean, ask the vendor one question the feature grid will not answer: what happens to your data and your learnings if the product shuts down. This category has earned that question.
The bottom line
The growth experiment management category proved the process works and then largely failed as a business. The winners of the next few years will not be trackers that watch your team do the work; they will be platforms that do the work with you.
Growth Method is the agentic platform built for B2B marketing teams that want campaigns planned, prioritised and measured against one goal. If that sounds like your team, get started with a 30-minute call with Stuart, our founder.
