Run more growth experiments.
Without more headcount.
Crux turns growth opportunities into structured paid acquisition and landing-page experiments, then tracks what worked and what to test next. You approve every experiment before launch.
Example experiment
Ready for reviewPaid search sends high-intent traffic, but only 2.8% request a demo.
Control vs security-first landing page, qualified demo request as the primary metric.
From ideas
to evidence
Crux gives a small SaaS team a repeatable experimentation process without hiring a full growth function.
See the workflowTypical workflow
- Ideas sit in a backlog
- Tests take weeks to set up
- Learning lives across docs
- No consistent prioritisation
- The same debates repeat
Crux pilot
- One ranked experiment queue
- Ready-to-run test plans
- One evidence trail
- Clear success metrics
- Each result informs the next test
One focused loop, repeated.
Start narrow: one goal, one channel, one conversion surface. Prove the loop before automating more.
See the product demo- 01
Connect
Bring one growth goal, one acquisition channel, your landing page and baseline data.
- 02
Diagnose
Identify the biggest bottleneck and the highest-value hypothesis to test.
- 03
Design
Create the audience, message, offer, page variant and success metric.
- 04
Approve
Review the experiment, budget and guardrails before anything changes.
- 05
Measure
Track results against the baseline and stop weak variants quickly.
- 06
Learn
Record the outcome, update what Crux knows, and choose the next test.
The founding pilot is intentionally narrow.
We are not trying to automate your entire growth stack on day one. We focus on one measurable acquisition and conversion loop, then expand only if it works.
Founding pilot scope
3 places| Area | Scope | Cadence |
|---|---|---|
| Growth goal | One measurable commercial goal | Set at kickoff |
| Acquisition | One active acquisition channel | Included |
| Conversion | One landing page or conversion journey | Included |
| Experiments | 3–5 structured tests | Across 6 weeks |
| Approval | Human sign-off before launch | Every experiment |
Your growth learning compounds.
Crux keeps the hypothesis, evidence and decision together, so every experiment improves what you test next.
See the evidence modelHypothesis
Security-first messaging will convert more high-intent traffic than generic productivity messaging.
Evidence
Variant B increased qualified demo requests from 2.8% to 4.1% over the test window.
Decision
Keep the winning message, roll it into paid search, then test proof and objection handling next.
Status Next test ready
You stay in control.
Crux keeps the process moving.
The MVP is deliberately human-approved. You set the goal, budget, brand rules and success metric before any experiment runs.
Goal
Choose one measurable commercial outcome for the pilot.
Focus1 growth goalBudget
Set the amount Crux is allowed to use for approved tests.

Nothing launches until you have reviewed the experiment.

Define brand, audience, claims and risk boundaries up front.

Agree the baseline and success metric before the test starts.
