Activation rate on mobile is 12 pp below desktop. Simplifying onboarding step 3 is your highest-leverage experiment.
What Merna does
Systematic growth, not guesswork
Experiment design
Merna takes your growth goal, proposes a testable hypothesis, selects the right metric to move, and sets up the experiment framework — control, variant, confidence threshold, and sample size.
Bottleneck identification
It maps your full AARRR funnel, detects where conversion rates drop furthest relative to industry benchmarks, and surfaces the highest-leverage intervention for each stage.
Loop mapping
Merna diagrams your acquisition and retention loops as a node graph — showing which loops compound, which ones leak, and where to apply force to create flywheel momentum.
Autonomous execution
From messaging variations to channel allocation recommendations, Merna runs the growth tactics it designs. You review results. You stop babysitting spreadsheets.
Capabilities
Built for founders who know
what a growth loop is
Merna is not a generalist AI that runs every department. It specialises in systematic growth — because depth beats breadth.
Growth experiment engine
Merna designs statistically valid experiments from a plain-English goal. It sets the hypothesis, defines the variant, picks the primary metric, and calculates the sample size you need before you run anything.
When results come in, it reads the data, declares significance, and proposes the next experiment — closing the loop automatically.
Acquisition loop intelligence
Identifies which acquisition channels compound over time versus which ones plateau. Maps referral, content, and paid loops to show you where virality already exists — and where to build it.
Retention cohort analysis
Runs cohort retention analysis automatically. Surfaces the behaviours that predict long-term retention and flags the drop-off points killing your LTV.
Funnel diagnostic reports
Benchmarks each AARRR stage against your sector, identifies your widest leaks, and ranks interventions by expected impact — so you always know what to fix first.
Autonomous tactic execution
From writing messaging variants to recommending channel budget reallocation, Merna executes the growth tactics it designs. You stay in the loop at the decision level — not buried in the detail level.
How it works
From goal to running experiment in minutes
Merna works alongside you as a growth co-pilot. You define the objective; it handles the design, setup, and execution.
Connect your metrics
Point Merna at your analytics — it reads your current funnel data, identifies your baseline conversion rates, and builds a map of your growth state before touching anything.
Define your growth goal
Tell Merna in plain language what you want to move — activation rate, paid conversion, 30-day retention. It translates your goal into a measurable primary metric and sets a realistic target based on your current baseline.
Review the experiment plan
Merna proposes a hypothesis, a control and variant, a confidence threshold, and the minimum sample size. You review and approve. No stats knowledge required — but the rigour is there if you want to inspect it.
Merna runs it
Execution happens autonomously. Merna monitors the experiment, detects when significance is reached, and stops early if a variant is clearly underperforming — so you never waste traffic on a losing test.
Insight and next action
Results land in your dashboard with a plain-language read on what changed and why. Merna recommends the next experiment in the sequence — building compound learning over time, not one-off tests.
The product
Three screens that run your growth operation
Growth Dashboard, Experiment Builder, and Growth Loop Map — the tools a growth engineer uses every day, run by an AI that never needs briefing twice.
Simplifying onboarding step 3 will increase activation rate by reducing cognitive load on first-time users.
FAQ
Answers to the questions that matter
How is Merna different from a general-purpose AI assistant?
General-purpose AI handles whatever you point it at. Merna is trained entirely on growth engineering — experiment design, funnel analytics, cohort analysis, loop mapping. It knows which intervention is statistically valid for your specific conversion rate, not just which intervention sounds reasonable. Depth over breadth.
Do I need a data team to use Merna?
No. Merna is built for data-savvy founders and growth leads who understand the concepts but do not have the bandwidth to run rigorous experiments alone. You do not need a SQL analyst or a statistician — Merna handles the methodology. You supply the goal.
What metrics and data sources does Merna connect to?
Merna connects to the analytics tools you already use. It reads your funnel data, activation events, and cohort retention to establish your growth baseline. Specific integration details are available after sign-up, as they depend on your stack.
How long does it take to run a first experiment?
From connecting your data to a running experiment is typically a matter of minutes. Merna establishes your baseline, proposes the highest-leverage hypothesis, and moves to setup immediately. The sample size and duration depend on your traffic volume, not on Merna.
Is Merna right for a very early startup, or do I need existing users?
Merna is designed for startups that have early traction or product-market fit signals — enough traffic and user data to run statistically valid experiments. If you have fewer than a few hundred active users per month, the experiments will take too long to reach significance to be immediately useful. At that stage, qualitative research is a better use of your time.
Who reviews the experiments before they run?
You do. Merna proposes every experiment plan for your approval before any variant goes live. The review step is mandatory — Merna executes autonomously once approved, but it never runs an experiment you have not signed off on.
