Royan AB is an established Swedish IT company headquartered in Stockholm. We build native mobile apps, autonomous AI agents, AI chatbots and pipelines, and modern websites for fintech, healthtech and SaaS teams across Europe, backed by a decade of senior engineering experience.
From a single Kotlin module to a multi-agent automation pipeline, Royan AB ships across the modern stack. Each engagement is led personally by a senior engineer.
Native Android in Kotlin and Jetpack Compose, built on MVVM / Clean Architecture. Pixel-perfect UI on phones, tablets, Wear OS and Android TV, with painless Play Store delivery and CI integration.
Swift and SwiftUI, built to Apple's Human Interface Guidelines. We design for the device (iPhone, iPad, App Clips) and we know the App Store review process intimately, including Sign in with Apple and StoreKit.
One Dart codebase, two production stores. We ship Flutter apps with native performance, custom motion, and platform adapters where it counts, built around Riverpod, BLoC and a strong testing culture.
Production voice systems: VOIP softphones, WebRTC apps, contact-centre integrations and voice-enabled AI agents. We build on SIP, Twilio, FreeSWITCH and Asterisk, with native iOS and Android clients. From a single softphone to a full inbound/outbound stack with call analytics, recording, and routing.
Autonomous agents that reason, plan, and act on your data, built with Claude, GPT-4 and open models, wired into your stack via tool use, function calling and RAG. From single-purpose research agents to multi-step workflow orchestration with LangGraph and custom planners. Every pipeline ships with evaluations, observability and a measurable cost ceiling.
Conversational AI grounded in your knowledge base and wired into your CRM, deployed where customers actually are: web, mobile, voice, WhatsApp, Slack and Teams. Multi-language, escalation-aware, with clean handoff to humans. We design the prompts, build the retrieval layer, and ship the eval harness so the bot can ship safely on day one and improve every week after.
Security checks and red-teaming across the full LLM pipeline: prompts, retrieval, tools, models, and the data they touch. We test for prompt injection (direct and indirect through documents), data exfiltration, jailbreaks, unsafe tool use, and PII leaks. Then we engineer the guardrails, monitoring and audit trails, with documentation aligned to SOC 2, GDPR and the EU AI Act.
Marketing sites and product surfaces engineered for speed, accessibility, and editorial quality. Every site we ship clears 90+ on Core Web Vitals, by the same people who built it, not a separate optimisation team.
Technical SEO, structured data, content systems and the analytics to prove it works. Core Web Vitals tuning, schema.org coverage, AI-search readiness (LLM citations, llms.txt), multilingual EU SEO, local search for Stockholm/Sweden, internal linking and dashboards measured against revenue, not vanity metrics. We move sites to page one, then build the measurement to keep them there.
Royan AB adapts to your stage. Whether you need a fully-staffed delivery partner, a senior advisor on call, or someone to put production-grade infrastructure under what you've already built, there's a model for it.
Idea to launch, owned end-to-end. Architecture, design, engineering, QA, store delivery, and the boring-but-critical maintenance afterwards.
Strategic technical guidance from a senior engineer who has been in the trenches. Architecture review, AI strategy, hiring loops, and the second opinion every team needs before a big bet.
The server-side foundation that keeps your product up and growing. APIs, cloud, observability, CI/CD, built to be operated, not just shipped.
The same five movements run every engagement. Tight feedback loops, written artifacts, and visible progress at the end of each, so the surprise is the product, not the bill.
Goals, users, constraints. We define success in writing: scope, timeline, and what "done" looks like.
System design, API contracts, infrastructure, and wireframes, all settled before any production code is written.
Two-week sprints, CI from day one, weekly demos. You see real software early and often.
Automated tests, manual passes, performance profiling and a security pass before users touch it.
Store submissions, deployment, monitoring, and the maintenance contract that keeps it healthy.
A senior toolbox, used carefully. New tech where it earns its place, proven tech where reliability matters more than novelty.
Royan AB is a Stockholm-based technology company, founded in 2025 to deliver senior engineering across mobile, AI, voice and the modern web. We work directly with founders, CTOs and product teams across Sweden and the EU.
As a registered Swedish AB (org nr 559573-6975, D-U-N-S 37-366-1245, SNI 62100) we operate with the transparency that European partners expect: clear contracts, traceable invoicing and real EU residency. Every engagement stays senior, focused and personal. The engineer you meet at kickoff is the one writing your code.
Ten years writing software, mostly on mobile. I started in native Android, moved into Flutter and iOS, built real-time voice and VOIP systems, and over the last few years have spent more and more time on AI agents, chatbot pipelines, and the security work around them.
Before Royan AB I led mobile architecture at fintech and healthtech companies, mentored engineering teams, and shipped products that ended up in the hands of hundreds of thousands of users. I started this company to do that work with more care, for fewer clients, and on better terms.
I write everything personally. If we work together, you get me, plus the senior network I bring in when a project needs more hands.
