The Story

Erikas is a designer-turned-entrepreneur from Lithuania (now living in Paris) who built 5 Shopify apps generating $4.5M/year with 90% profit margins - all with zero marketing spend. His main app, Kaching Bundles, alone does $400K MRR.

He started his journey making just $2/hour at a local web design agency right after school. While freelancing, he stumbled upon the Shopify Partners page and saw that the top 25% of Shopify app developers make nearly $300K/year. That number seemed huge compared to his freelance income, so he decided to build in the Shopify ecosystem.

Since launching in August 2022, his apps have generated over $400 million in additional revenue for merchants using them.

The Shopify App Opportunity

Why Platforms Work

  • Shopify App Store does all the marketing for you
  • Built-in distribution to millions of merchants
  • Platform handles payments and trust
  • Focus on product, not marketing

The Gap Erikas Found

  • Solo developers/indie hackers: Great technical skills but poor UX
  • VC-backed companies: Great UX but move slowly (months/years for new features)
  • His opportunity: Combine great UX with fast iteration

Finding Winning Ideas

Three Criteria

  • Easy to build - Must be buildable in a couple months max
  • Broad market - Useful for any Shopify store (easier to market)
  • Low competition - Space to squeeze in

Validation Process

  • Joined Discord communities of dropshippers
  • Joined e-commerce Facebook groups
  • Posted a screenshot of his app design (not even built yet)
  • Post blew up: 100+ likes, tons of comments asking where to download
  • That was his validation signal

The Apps

Kaching Bundles (Main App)

  • $400K MRR
  • Helps merchants create product bundles to increase average order value

Other Apps

  • Kaching Post Purchase Upsell
  • Kaching Pop-up Upsell
  • Kaching Card Drawer Upsell
  • All in the discount/upsell category

The Review Strategy (Game Changer)

Why Reviews Matter

  • Reviews drive App Store rankings
  • Rankings drive organic installs
  • Organic installs = $0 marketing spend

How to Get Reviews

  • In-app prompts - Ask for reviews directly in the product
  • Monthly emails - Show merchants how much revenue the app generated, then ask for review
  • Customer support - 95% of reviews come from support interactions

The Gamified Bonus System

  • Monthly leaderboard tracking who gets most reviews
  • "Persuader of the Month" award
  • Calculate conversion rate: times asked for review → reviews received
  • Bonuses for each review obtained
  • Creates healthy competition among support team

Support Quality

  • 24/7 customer support
  • All agents are highly technical (can dig into merchant's code)
  • Top-notch support = happy customers = 5-star reviews

Building Without Technical Skills

Finding a Co-Founder

  • Treat it like sales - you're selling someone on your vision
  • Posted in local developer Facebook group
  • Pitched his value: Shopify experience, design skills, existing client base
  • Found technical co-founder who believed in the vision

Design Process

  • Study competitors deeply
  • Go through their UX, take notes on likes/dislikes
  • Create design that's objectively better
  • Build with co-founder

Monetization Strategy

Launch Free First

  • Reduces friction for installs
  • More installs → more reviews → better rankings
  • Grandfather early users when you add pricing
  • Only monetize new users

Pricing Model

  • Subscription tiers based on usage
  • Always offer free trial
  • Full refunds, no questions asked (risk of 1-star review too high)

Tech Stack & Tools

  • Slack (team communication)
  • Intercom (customer support)
  • Features.vote (feature suggestions from users)
  • Linear (internal task management)
  • Mantle (Shopify-specific metrics, funnels, affiliate partnerships)

Business Numbers

  • $4.5M ARR
  • 90% profit margins
  • 5 Shopify apps
  • $0 marketing spend
  • 2 years to scale

Day in the Life

  • Wake up whenever (no alarms)
  • Check emails in bed, scroll Twitter
  • Differentiate tasks: quick wins (30 min) vs. deep work
  • Doesn't feel like work - passionate about what he does
  • Doesn't count time

Key Advice

For Starting Out

  • Two people are enough: designer + developer
  • Do customer support yourself initially to understand pain points
  • Scale team only after you start getting more tickets

For Finding Ideas

  • Build on platforms with built-in distribution
  • Look for gaps between indie hackers (bad UX) and big companies (slow)
  • Validate with real users before building

Community

  • Hang around other builders
  • Learn from their mistakes
  • Find co-founders in communities
