Product engineering
We take a spec and ship a production product — not a prototype that gets replaced when the real work starts. The architecture on day one is designed for what comes after launch, so growth doesn't force a rewrite.
Built for founders, by founders
From idea to live product.
We engineer software that ships fast and survives scale.
Stackern is two senior engineers who ship production software in weeks. You work directly with the people writing the code — no account managers, no hand-offs, no surprises.

Capabilities
Everything between a spec and a shipped product.
One small senior team that designs, builds, and deploys — so nothing gets lost in the hand-off between disciplines.
AI product features
Retrieval pipelines, agents, and copilots built to handle real inputs and real edge cases. We wire AI into your product where it earns its place — not where it makes a good screenshot.
Web & mobile apps
Next.js and React Native interfaces that load fast, hold up across every viewport, and look like someone with taste built them. We design and build in the same team, so nothing gets lost in translation.
Backend & infrastructure
APIs, auth, data models, and deployment infrastructure designed upfront — so scaling doesn't mean rewriting what we built in week one.
Product design
Interface and interaction design done by the same engineers shipping the code. What you see in the design is what gets built — no dilution between intent and implementation.
Fractional CTO
Technical direction and architectural judgment for the period when you need someone thinking at the system level, not just the feature level.
A clear path from idea to in-production.
No discovery theatre, no endless decks. A tight loop that puts a real product in front of real users, fast.

Pressure-test the idea
We cut the scope to what proves the idea and agree in writing what 'done' looks like — before we write a line of code.

Why Stackern
Senior judgment, without the agency overhead.
The speed of a freelancer, the reliability of a studio, the ownership of an in-house team. None of the parts that slow you down.
Two engineers. No bench.
You talk to the people writing the code. There is no project manager in between and no junior doing the work while a senior reviews it.
Cut first, build second.
Before we write code, we argue about what to cut. The scope we agree on is what gets built properly — not a prototype you replace after the raise.
Your code from day one.
Everything lives in your repository under your account. No proprietary tools, no platform lock-in. When we're done, your next hire inherits something they can understand.
AI where it earns it.
We use AI to move faster and build things that would otherwise take weeks. We don't use it to dress up what we're charging you for.

FAQ
The questions founders ask first.
Still unsure? A 20-minute call answers most of it faster than reading.
Usually within a week. We take a limited number of builds at a time so that the engineers you talk to are the ones who do the work. If a slot is open, we can scope and start fast.
