Hello, I'm Gustav

I help companies build the right thing—from the first idea to launch and beyond. Strategy, design, development, shipping. I can be your entire tech and product team, or work alongside your existing one.

I leverage modern tools—LLMs, agents, automation—to move fast. Some I build myself, others I adapt. The goal is always the same: build what's needed, ship fast, iterate smarter.

Products I've built have helped companies land investment rounds and expand into new markets. I've been in the startup space for a long time—starting companies, building products, failing, learning. These days I know what matters and what doesn't.

Most recently I was Co-Founder and CTO at Southern Lights, building decision intelligence tools for clean energy projects. I joined, built the product, launched it, and within 10 months the company value increased 10x. Before that, I co-built Afloat to help freelancers manage their finances, led infrastructure and team rework as CTO at Contentor, and founded Mynewsflash to reshape the Nordic news landscape.

If you're building something interesting, message me or find me on LinkedIn and let's connect the dots.
