Consumer App / Web Revenue Growth Consultant

Erwin Zheng Lv

Tsinghua SEM | IAP Monetization Consultant

Founder of Zheng Lv Planet • AI Tools / Subscription Product Monetization • Commercialization Data Infrastructure

I mainly help consumer App and software product teams solve problems around revenue growth, subscription conversion, IAP monetization, and data-based diagnosis and revenue feedback.

I have long focused on consumer product monetization growth. I led subscription revenue for a leading global AI education product from $4M to over $10M, while significantly improving paid conversion, subscription cancellation rate, and LTV. I currently provide App / Web monetization consulting.

Revenue growth, subscription monetization, experiment payback, and data infrastructure as one complete system

It is not about changing one page. It is about seeing value perception, pay triggers, pricing, trial, renewal, and ROI on the same map.

From landing and activation to Paywall and payment success.

02

Subscription Growth

Trial-to-paid, renewal, cancellation, and win-back.

03

Paywall

Layout, copy, benefits, and trigger timing.

04

A/B Testing

Hypotheses, traffic split, guardrails, and revenue payback.

05

Data Infrastructure

Tracking, dashboards, user tags, and channel ROI.
