The journey, decisions, and context behind this milestone

How Shalom actually did it

6/7 funnel stages sourced

Reconstructed from Shalom'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

The idea was born out of a coffee meeting between co-founders Hillel and Shalom in late 2013; the app went live a few months later.

“Hillel & Shalom met for coffee in late 2013 to discuss the idea of Invoice Ninja.”

Our Story - Invoice Ninja

Validation

Built first, validated after

MvpValidated

The founders skipped formal pre-build validation and focused on shipping a working app first, telling early Hacker News users that perfecting the product came before monetization.

Hillel Coren told early users the priority was the product, not revenue, in the days after launch.

“Our first concern is to perfect the application, making money will come later.”

Invoice Ninja launched to Hacker News' front page in March 2014, and Hillel Coren personally answered feedback in the comments during the thread.

Acquisition channels, and whether they worked

Communities · Hacker News (launch thread)LaunchWorked

The founder engaged directly in the Hacker News comments during launch, answering feature and pricing questions in real time.

Per Invoice Ninja - Hacker News launch thread (Hillel Coren's comments)

Communities · Self-hosted open-source / GitHub communityScalingWorked

During the v2 rewrite, self-hosted users kept receiving community-built features through a dedicated GitHub branch while the hosted product moved forward.

“For self-host users we’ll create a branch in our GitHub repository which will include new features added by the community.”

Announcing a rewrite/version 2.0 without causing a panic - Hillel Coren

Being transparent about the rewrite and incorporating community feedback before publishing the announcement kept the open-source community supportive through a risky transition.

“I’m extremely grateful to our community for their help here and of course their ongoing support of our project.”

What didn't work

Tech choiceScalingCost: time

The team spent roughly six months rewriting the app in Vue.js before abandoning that approach for Flutter Web.

“We were about six months into our big rewrite using Vue.js when we had a chance to try Flutter Web”

Adapting our Flutter mobile app to web and desktop - Hillel Coren

What they did instead: Switched the rewrite to Flutter Web after trying it, valuing the shared codebase across mobile, web and desktop.

Tech choiceScalingCost: time

Flutter Web was used to build the client-facing web app, but the team later concluded it was not the right tool for that job.

“Flutter Web is truly amazing but not the right fit for our use case”

Adapting our Flutter mobile app to web and desktop - Hillel Coren

What they did instead: Rebuilt the web app in React while keeping Flutter for the desktop and mobile apps (shipped as "Invoice Ninja React" in 2023, per the founders' own company timeline).

How it changed as they grew

What broke as they grew

Around five years after launch, accumulated technical debt from the original framework forced a full v2 rewrite, which the founders navigated carefully in public to avoid alarming their self-hosted user base.

“a combination of domain considerations and changes to our underlying frameworks have made our code less than the perfect ideal we’re striving for”
