How Momingo grows

3 tactics and 2 figures from 3 interviews.

Momingo is a transit app with bus and train alerts and a paid Pro tier. Most of its reported growth came from turning people who closed the paywall into a free week of Pro, with ChatGPT-style answer content and three-month payback on ads as supporting moves.

Momingo gave people who closed the paywall a free week of Pro, with Pro-labelled transit alerts and a discount before it ended; paywall closers who paid rose from 0.4% to 4.5%.Momingo
Momingo published answers to questions people ask AI assistants about the app, such as whether it supports a given city; the founder was reported to get traffic from ChatGPT this way, with no numbers shared.Momingo
Momingo judged ad spend on what a cohort earned within three months against acquisition cost, rather than first-month return, which allowed a higher cost per customer; no results were given.Momingo

Momingo's 3 tactics

Momingo · B2C · bus and train times app

When someone closes the paywall, give them a free week of Pro anyway

Paywall closers who paid rose from 0.4% to 4.5%

Onboarding is benefit-led (not features) with social proof on every screen. Tapping the free trial shows 'Welcome to Pro'; tapping X shows 'Enjoy a week of Pro on us' and walks the user through Pro features. During the week, Pro-labelled notifications (bus/train alerts) show what goes away without a subscription, and ads are removed. Before the week ends the app says it's about to end, then offers a discount.

Write answers to "Does [app] work?" style questions so ChatGPT recommends you

Founder says he gets ChatGPT traffic; no numbers

Create content answering the questions people ask AI assistants about the app: 'What is Momingo? Does Momingo work? Can I use Momingo? Does Momingo support Washington, D.C.?' Steve suggests the same for feature questions ('Does BrainJams support language learning with spaced repetition?').

Judge ad spend on 3-month customer value, not first-month return

Rather than month-one ROAS (spent $1,000 this month, made how much this month), evaluate how much a cohort makes within three months against CAC, which allows paying a higher CAC.
