## The panel's verdict

Justuno is a conversion optimization platform whose documented testing surface is its own popups and overlays: A/B and multivariate comparison of copy, imagery, layouts, offers, triggers and placement, with the best-performing version applied automatically. The scores are strongest on data and integrations, at 3 to 4, crediting a Google Analytics integration, syncs with email, SMS, ecommerce and customer-data tools, CSV export of subscriber lists and self-service export of customer data. Consent and tracking spread from 2 to 4: the higher scores credit EU-only consent checkboxes, stored opt-in and consent-removal timestamps and a signable GDPR Data Processing Agreement, while the data protection officer's 2 reflects that this tooling governs the customer's forms — we found no public information on what the tracking script stores or does before consent. Statistical rigour scored 0; performance impact 0 to 1, where the only statement is the marketing line that tests run 'without slowing down your campaigns'. Sovereignty ranged 0 to 2: Justuno, Inc., California law, USD payment, with no public hosting or subprocessor information. No tier prices are published.

**Speaks for it:**
- Documented consent tooling: consent checkboxes that can be limited to EU visitors, stored signup and consent-removal dates, opt-in timestamps and per-subscriber deletion.
- A Data Processing Agreement with GDPR terms, signable by customers processing EU/EEA individuals' data.
- Data and integrations scored 3 to 4: a Google Analytics integration, syncs with email, SMS, ecommerce and customer-data tools, CSV export of subscriber lists and self-service export of customer data.
- The terms state commercial mechanics plainly: quarterly or annual billing, net thirty, taxes excluded, 1.5 percent monthly late interest and a 30-day money-back guarantee on new customer annual subscriptions.
- The terms confirm the customer owns Customer Data and can export it at their discretion.

**Held against it:**
- Statistical rigour scored 0: the only documented decision rule is automatic application of the best-performing version, with no public information on the method, sample-size or duration guidance, or peeking protection behind it.
- Performance impact scored 0 to 1, resting on the marketing claim that tests run 'without slowing down your campaigns', with no published script size, loading behaviour, flicker handling or Core Web Vitals figures.
- Experimentation scope scored 2 to 4: testing is confined to the platform's own popups and overlays, with no public information on server-side or SDK delivery, split-URL tests, holdouts or mutually exclusive experiments.
- Sovereignty scored 0 to 2: contracting is with Justuno, Inc. under California law in US dollars, and we found no public information on hosting location, data residency or a subprocessor list.
- We found no public information on a documented API, visitor-level export of experiment results or warehouse access, so a declared winner cannot be re-checked in your own data.

**Best for:**
- You want to A/B or multivariate test popup and overlay copy, imagery, layouts, offers, triggers and placement, with the best-performing version applied automatically.
- You collect EU visitor consent and need documented records — opt-in timestamps, consent-removal dates, EU-only consent checkboxes — plus a signable GDPR Data Processing Agreement.
- You want subscriber data synced into an existing stack — Google Analytics plus email, SMS, ecommerce and customer-data tools — with CSV export of subscriber lists.
- You want popups launched at engagement moments using AI Smart Timing and real-time visitor behaviour.

**Avoid if:**
- You need a full experimentation programme — server-side or SDK delivery, split-URL tests on your own pages, holdouts or mutually exclusive experiments.
- Your declared winners must be statistically defensible to finance or clients, with documented methods, sample-size guidance and stopping rules.
- You must verify performance cost before putting a script on every page — the captured pages offer only the 'without slowing down your campaigns' marketing claim.
- You contract only with EU entities under EU governing law — the captured pages show Justuno, Inc., California law and US-dollar payment.

### The judges

- **The Growth Lead** (v1.0): Runs the testing programme for a German marketing team and reports uplift to the board. Wants a visual editor the team can use without a developer, targeting that goes beyond the URL, and results she can defend when finance asks where the promised revenue went.
- **The E-Commerce Manager** (v1.0): Owns a shop where a tenth of a second of load time shows up in the conversion rate. Wants personalisation that can be tested against a control, a snippet that does not flicker the product page, and a traffic-based price that does not jump a tier every December.
- **The Product Engineer** (v1.0): Ships experiments behind feature flags and would rather not ship a third-party script at all. Wants server-side SDKs for the stack in use, edge delivery, metrics computed in the warehouse the team already trusts, and an API good enough to build internal tooling on.
- **The CRO Consultant** (v1.0): Sets up testing programmes for several clients and has to recommend a platform each can afford and defend. Reads for multi-project management, clean analytics integration, a consent setup a client's DPO will sign off, and a traffic metric she can estimate before the contract.
- **The Data Protection Officer** (v1.0): Has to answer whether the test script may run before the consent banner is answered, and usually finds the vendor has not said. Wants the storage keys listed, a documented consent-pending mode, visitor data processed in the EU, and a published subprocessor list that includes the CDN.
- **The Skeptic** (v1.0): A statistician who has watched too many "winners" regress to zero. Reads for the method by name, what stops a team from peeking, sample ratio mismatch checks and multiple-comparison corrections — and treats a "probability to beat" without documented assumptions as marketing.
