Software that sails true.
Essaim Apps Oy is a Finnish product studio. We chart the course, trim the sails, and crew the build — delivering platforms, AI systems, and cloud infrastructure that reach port on time.
The fleet
One crew. Every heading.
We partner with product and engineering leaders to design, build, and sail software that becomes core infrastructure for their business.
AI & Machine Learning
Navigate uncharted waters with production-grade LLM applications, RAG systems, and custom models tuned to your workflows.
Product Engineering
End-to-end web and mobile platforms — from keel-laying to launch and every league beyond.
Platform & DevOps
Cloud-native architectures on AWS, GCP, and Azure. Kubernetes, IaC, and observability trimmed for fair winds.
Security & Compliance
GDPR-ready systems, SOC 2 alignment, and secure-by-default engineering — a lifeline you can trust in any storm.
Modernization
Weigh anchor on legacy systems. Unwind monoliths and set course for modern, maintainable services.
Advisory & CTO-as-a-Service
A steady hand on the tiller — fractional technical leadership for scale-ups charting architecture, hiring, and roadmap.
How we sail
Small crew. Clear heading. Zero drift.
Every voyage is led by senior engineers. No pyramids, no handoffs — the people who plot the course are the people at the helm.
Chart
We map the waters — business context, user needs, and technical currents — before setting a single sail.
Rig
Architecture, product design, and a delivery plan — a compact chart the whole crew can navigate by.
Sail
Weekly production-grade releases, with the instruments and observability that keep every heading honest.
Harbor
A long voyage together: we operate, iterate, and hand the wheel over cleanly whenever your in-house crew is ready.
