Building products that work, with teams that scale

I am Felix Hellstrom. AI product engineer, fractional CTO, and partner at Stormfors. Based in Stockholm.

Background

Design, development, and business strategy

I operate at the intersection of design, development, and business strategy. My work spans from hands-on product engineering to boardroom-level technical strategy. I build things, and I help others build things better.

As a partner at Stormfors, I work with enterprise clients on digital transformation, AI integration, and go-to-market acceleration. Through Klarhimmel, I take on fractional CTO engagements with growing companies that need strategic technical leadership without the overhead of a full-time executive hire.

My client work includes Porsche Club Sweden, ROL Group, Precis Digital, and Miramis. I specialize in helping businesses make the right technical decisions at the right time, whether that means choosing a tech stack, integrating AI, or rebuilding a legacy platform.

Approach

How I work

Ship fast, learn faster

Speed is a competitive advantage. I help companies go from idea to launched product in 30 days, not 6 months.

Technology serves the business

I pick the right tool for the problem, not the newest framework. Boring, proven technology ships faster and breaks less.

AI as a practical tool

AI integration should solve specific problems, not be a buzzword in your pitch deck. I focus on implementations that deliver measurable value.

Honest assessment

I will tell you if your idea has flaws, if your architecture needs work, or if you should rebuild instead of patch. Accurate diagnosis beats comfortable agreement.
