The Full Story

TL;DR

Erikas Malisauskas beendete die Freiberuflichkeit und baute 5 Shopify Apps auf, die $4,5M pro Jahr ohne bezahltes Marketing generieren.

Ich wollte die Freiberuflichkeit beenden, darum baute ich ein Portfolio von Shopify Apps auf. Jetzt generieren sie über sechsstellige Summen pro Monat.

Die Flucht aus der Freiberuflichkeit

Ich war jahrelang als freiberuflicher Entwickler tätig. Es war gutes Geld, aber ich wollte etwas Eigenes aufbauen - Produkte, die wiederkehrende Einnahmen generieren würden.

Das Portfolio aufbauen

Ich habe über fünf Apps gebaut, darunter Kaching Bundles, Kaching Post Purchase Upsell, Kaching POP Discount Upsell und Kaching Cart. Jede App hilft Shopify-Händlern, ihren durchschnittlichen Bestellwert zu erhöhen.

Der $0-Marketing-Ansatz

Meine Apps generieren $4,5M pro Jahr ohne Marketing-Ausgaben. Wie? Der Shopify App Store bietet organischen Traffic. Wenn du Apps baust, die Händler lieben, hinterlassen sie Bewertungen, was mehr Installationen antreibt.

Fokus auf Händler-Erfolg

Bei jeder App konzentriere ich mich auf eine Sache: Händler beim Geldverdienen unterstützen. Bundle Apps erhöhen den AOV, Upsell Apps nutzen zusätzliche Einnahmen, Cart Apps reduzieren Warenkorbabbrüche.

Jahresumsatz: $4,5M
Marketing-Ausgaben: $0
Anzahl der Apps: 5+
Primäre Plattform: Shopify
Einnahmemodell: SaaS-Abonnements

Key Takeaways

Marktplatz-Vertrieb (Shopify App Store) kann bezahltes Marketing vollständig ersetzen

Baue mehrere Produkte für dieselbe Zielgruppe auf, um kumulatives Wachstum zu erreichen

Konzentriere dich auf Händler-ROI - wenn deine App ihnen Geld verdient, zahlen sie weiter

Freiberufliche Erfahrung hilft dir zu verstehen, was Unternehmen wirklich brauchen

How Erikas actually did it

7/7 funnel stages sourced

Reconstructed from Erikas's own published sources. Quoted claims are the founder's words, verified verbatim; anything marked as our analysis is exactly that.

Where the idea came from

Pivot from prior productPivot from Guarantees & Features Icons Shopify app (his first product, sold for $250K)

Erikas funded and launched Kaching Bundle Quantity Breaks using the money and experience from selling an earlier Shopify app (a product icons/guarantees app) for $250K.

“We have sold this app at $6700 MRR for $250K.”

Validation

Built first, validated after

OtherValidated

Chose the Shopify discounts category and the specific bundles widget by surveying live merchant stores after selling the first app, instead of running a formal pre-build demand test.

Asked how the Kaching Bundles idea came about, Erikas says the team went after a bigger market than their first app, settled on the discounts category, and picked the widget after looking at hundreds of live Shopify stores. The quote comes from a Q&A written by another Shopify app founder, so it is treated as implied rather than stated.

Per 5 questions Q&A with Shopify app founders #3, by Marton Kosdikovacs, quoting Erikas Mališauskas verbatim on the Kaching Bundles idea

MvpValidated

Shipped a first working version within a few weeks of the idea and used post launch traction, not pre-build research, as the demand signal.

Erikas contrasts a first startup that took three years to launch with his current rule of a maximum six weeks to an MVP, and says the top app in the portfolio (Kaching Bundles, which he describes elsewhere as passing $3M in two years) was launched within a few weeks of the idea.

“Our top app was first launched in few weeks after an idea came to mind.”

Erikas Mališauskas LinkedIn post, "My first startup took 3 years to launch" (his own MVP speed rule and the top app's launch timing)

OtherValidated

Treated the playbook proven on the first Shopify app as the validation for entering a much more competitive niche, rather than testing the new niche from scratch.

In his $1M MRR retrospective Erikas frames the second app as a deliberate replication: same playbook, harder niche, and it reached $100K MRR in about a year.

“we launched a new app in a much more competitive niche, used the same playbook and reached $100K MRR in about a year”

Erikas Mališauskas LinkedIn post, "we've reached $1 million in MRR" (five lessons, including replicating the first app's playbook)

First test users

Online community~1000 usersFree testersFacebook dropshipping groups

In the Indie Hackers interview about the current Kaching app portfolio, Erikas describes seeding early users by posting the app for free in Shopify dropshipping Facebook groups; some posts went semi-viral and pushed the app onto the Shopify App Store trending list, reaching 1,000 users in the first month. The interview does not name which specific app this refers to, though it is presented as describing the current flagship.

Per Indie Hackers (case study by James Fleischmann, quoting Erikas Mališauskas)

First paying customer

Online communityFree to paid upgrade$14.99

Merchants who first installed for free later converted onto paid usage-based tiers once the app was monetized; the entry Basic plan is $14.99 with all features, with merchants upgrading to higher tiers as the app drives them more revenue.

Of roughly 15k monthly installs, half is attributed to word of mouth via branded search for the "kaching" name.

Another 40% of monthly installs comes from unbranded, organic App Store keyword search.

What didn't work

OpsScalingCost: time

After launching a second portfolio app (Kaching Post Purchase Upsell) in early 2024, the founders split attention across apps and the new app's MRR stalled around $5-6K.

“Kaching Post Purchase Upsell app was left without much care. It reflected in MRR - chart flattened around $5-6K.”

Erikas Mališauskas on X (@malisauskasLT)

Erikas and his cofounder tried to scale horizontally across multiple apps at once, then had to redirect focus to Kaching Bundles, which was growing fastest, leaving the second app under-resourced.

“We were excited to scale horizontally building more apps with @DonatasStundys but quickly enough we realized we need to focus on Kaching Bundles which was growing like crazy.”

Erikas Mališauskas on X (@malisauskasLT)

What they did instead: In early 2025, assigned a dedicated developer with a revenue share to each app instead of splitting founder attention; the previously stalled app grew +150% in the following 3 months.

How it changed as they grew

Today: 2 people (Erikas Mališauskas + technical cofounder Donatas Stundys)

Bootstrapped · $250,000

What broke as they grew

Founder attention split across a growing app portfolio, rather than product or market factors, was the binding constraint on scaling secondary apps; dedicating a developer (with revenue share) per app relieved it.

“Moral is simple here - where focus goes, progress grows. Everything else stays stuck.”
