Web2App Localization Case Study: How Leya AI Scaled Its Funnel 10×

In short

• Leya AI was already running web funnels on one of the leading web-funnel platforms, and switched to web2wave for a more custom, hands-on partnership.
• Using web2wave's AI localization, Leya adapted its funnel into 30+ languages and scaled it across markets.
• Moving first into languages competitors couldn't reach meant higher ROAS and lower CPA: a real first-mover edge, with each new market launching in a few clicks rather than a rebuild.
• In its first couple of months on web2wave, the funnel scaled close to 10× while conversions improved.
• Web2App became a repeatable, end-to-end growth layer the team runs and optimizes across markets.

The challenge

Leya AI was scaling paid acquisition and already had web funnels live, on one of the web-funnel providers. The setup worked, but the team wanted a partner that would move at their pace: fewer constraints, faster iteration, and an approach shaped around Leya's specific goals rather than a fixed template. They wanted more control over the journey before app install, and a team that would build with them, not just host them.

‍

Why Leya switched to web2wave

Leya moved its Web2App funnels from a different funnel platform to web2wave. The difference was the approach: more custom, more agile, and genuinely built around Leya's needs, with the web2wave team prioritizing what mattered most and going the extra mile to ship it. That partnership is why Leya kept building on web2wave rather than looking for alternatives.

What Leya built

Leya's growth team launched a Web2App funnel on web2wave: a web journey where users first move through a personalized quiz, grasp the product's value, and see a relevant offer before continuing into the app.

From there they made it their own, running experiments across onboarding, paywall structure, messaging, offer mechanics, and pricing logic, all without touching a mobile release. Crucially, they leaned on web2wave's AI localization to adapt the funnel (quiz questions, copy, and value propositions) into many languages, market by market.

What changed

Speed and ownership

Instead of waiting on release cycles, the marketing team now launches pricing experiments, reworks quiz flows, and adapts funnel messaging on its own schedule.

Localization as a scaling lever

Localization turned into a real scaling lever, and an unusually effortless one. With web2wave's AI localization, taking the funnel into a new market took a few clicks or a quick call rather than a full project, so Leya pushed across 30+ languages fast. That speed let them move first into languages competitors hadn't tapped. By the team's account, being early in those markets meant higher ROAS and lower CPA than the crowded, English-first markets everyone else fights over.

End-to-end analytics

The team centralized analytics across the full journey: ad click, quiz start, quiz completion, checkout, subscription, app install, making drop-off points obvious, funnel variants easy to compare, and optimization easy to prioritize.

‍

The outcome

The results came fast. In its first couple of months on web2wave, Leya scaled its funnel close to 10×, with conversion-to-subscribe roughly doubling and more than half of quiz-starters completing the flow. Just as importantly, web2wave took the operational headache out of going global: instead of rebuilding per market, Leya spun up new geos in a few clicks. That let the team scale worldwide, into 130+ countries and 30+ languages, including ones competitors couldn't reach. By their own account, being first in those markets delivered higher ROAS and lower CPA. A brand-new web channel became a worldwide, first-mover growth engine spanning acquisition, onboarding, and monetization.
