We build web apps, mobile apps, and SaaS platforms.
Senior expertise. AI-powered velocity.
AI-native software studio
Einder is an AI-native software studio. We build custom software — web applications, mobile apps, SaaS products, and automated workflows.
We're small by design. No junior developers, no project managers in between, no overhead. Just senior engineering expertise augmented by AI tooling — which means high-quality work delivered faster than you'd expect.
We speak your language
"Einder" is old Dutch for horizon — the edge of what's visible, where the present meets possibility. We build software that looks forward.
What we build
Custom Web Applications
Dashboards, platforms, internal tools — built to fit your business, not the other way around.
SaaS Development
From MVP to production. We help you validate fast and scale when ready.
Mobile Apps
Cross-platform apps with Flutter. One codebase, native performance.
Automated Workflows
AI-powered pipelines, integrations, and background jobs that run while you sleep.
Legacy Modernization
Stuck with outdated systems? We migrate incrementally — no big bang, no downtime.
Consulting & Architecture
Not ready to build yet? We help you define requirements, evaluate options, and plan your technical roadmap.
Engineering with perspective.
Senior-only
No handoffs to juniors. The person you talk to is the person writing the code.
AI-native
We use AI tooling throughout our workflow — code review, automation, documentation. You get speed without sacrificing quality.
Spec-driven
Every feature starts with a clear specification. We agree on what we're building before writing a single line of code. No surprises, no scope creep.
Documented
Every step of the process is documented — decisions, architecture, changes. You'll never be left wondering why something was built a certain way, and you'll never be locked in.
No overhead
No account managers, no layers. Direct communication, fast decisions.
Long-term thinking
We build systems meant to last and evolve, not just ship and forget.
