StackLabs

Clarity before you invest in code.

We plan, build, and ship web, cloud, blockchain, and AI products for founders and growing teams.

What we build

Nine disciplines, one team. Pick a single service or lean on us for the full build.

Web Development

End-to-end product development, from system architecture to a shipped, maintained release.

Mobile App Development

Native and cross-platform apps for iOS and Android, built on the same stack as your backend.

AI & Automation

AI-powered chatbots and workflow automation that cut manual hours.

Cloud Solutions

Infrastructure built for growth: cloud, on-prem, or self-hosted with Docker.

Security Audits

Penetration testing and code review that catch vulnerabilities before your users do.

Data Analysis

Statistical analysis and pattern recognition that turn raw data into decisions you can act on.

Blockchain

Smart contracts and on-chain systems built for real usage.

AI Production Readiness

Audits for AI-built apps: security, scaling, and code quality checked before real users show up.

Technical Consultancy

Architecture and feasibility review before you commit budget.

How we work

Milestone-based, always. You test what we build before a single euro changes hands.

Scope

We break the build into milestones together, so you know exactly what's being delivered and when, before anything starts.

Build

We build the first milestone. You get real visibility into progress, not radio silence until launch.

Test

You get working software and put it through its paces yourself. Nothing is invoiced until you confirm it does what it's supposed to.

Pay & repeat

You pay for what you just tested and approved. Then we move to the next milestone, or scale what's already live.

Engagements built around outcomes

Six ways to work with us: milestone-based projects or an ongoing retainer, never paid upfront.
