The Challenge

What they were up against

Stackr's team had an idea for a developer productivity tool — but no marketing channel, no distribution, and no UI. They needed the tool built AND a go-to-market strategy baked into the product design. Their goal: 8,000 active engineers in 6 months.

Our Solution

How we solved it

We designed the Stackr brand and built three surfaces simultaneously: a VS Code extension, a CLI tool, and a cloud dashboard. We shipped a viral 'generate your stack report' feature on launch day that drove organic sharing. Integration with Supabase gave them user analytics from day one. They hit 8,000 active developers before their 6-month mark.

The viral launch feature Fyutrex built drove more growth in one day than we'd managed in two months of manual marketing. They think product AND growth.

Insights

Key learnings from this project

Hard-won insights our team took away — the kind of knowledge that only comes from building in production.

Building distribution into the product (viral sharing, referrals) from day one was worth more than any marketing budget.

Shared TypeScript libraries across VS Code, CLI, and web dashboard reduced total engineering effort by ~40%.

Developer tools live or die on first-run experience — we spent disproportionate time on onboarding UX.

FAQ

Common questions answered

Can't find what you're looking for? Get in touch and we'll answer any question directly.

How did the viral stack report feature work?
Users generated a visual summary of their tech stack that was designed to be shareable on social media. Each report linked back to Stackr, creating an organic acquisition loop.
Did you build all three surfaces at once?
Yes — parallel workstreams. One engineer focused on the VS Code extension, another on the CLI + dashboard. Shared TypeScript libraries kept them in sync.
How did you hit 8K users without paid ads?
Product-led growth: the viral feature drove initial traction, the referral system compounded it, and the high marketplace rating drove ongoing organic discovery.
