We're an AI-powered digital agency. Websites, games, apps and digital products — conceived and built with artificial intelligence, refined by humans.
A new agency, built on a new way of working.
MSTR Corporation was founded in late 2025 on a simple conviction: AI doesn't change whether digital products get built — it changes how fast and how precisely. We use AI-powered tools at every stage, from concept through design and code to final polish.
The result isn't a shortcut. It's more time for what actually matters: thoughtful decisions, tight feedback loops with our clients, and a level of quality usually reserved for much larger teams.
Every line of code, every design and every decision is reviewed and owned by us. AI accelerates the execution — the responsibility stays human.
Using AI isn't about doing less — it's about cutting out everything that doesn't need a human hand, so the effort we do spend goes into decisions that matter. That's how a two-person team ships at a pace agencies ten times our size can't match — not by working less, but by wasting nothing.
One founder. Two supervised agents that never sleep.
MSTR Corporation runs lean by design — one human directing two custom-built AI agents through every stage of a project.
Sebastian W.
Founder & Direction
Sebastian founded MSTR Corporation and stays hands-on with every project, from the first call to the final launch. He directs NOVA and KERN, reviews every decision, and is the one person you'll actually talk to.
Felix K.
Supervisor & Marketing
Felix keeps a second, independent eye on everything NOVA and KERN produce — catching edge cases, checking quality against the brief, and making sure nothing ships that hasn't been properly reviewed.
NOVA
Design & Creative Agent
NOVA handles visual design, UI systems and brand direction — turning a rough idea into a coherent look in hours instead of weeks. Every output is reviewed by Sebastian before it ships.
KERN
Engineering & Build Agent
KERN writes and structures the code — from a single landing page to full application architecture. It works fast and iterates constantly, with Sebastian checking every build.
