Hello, I'm Gustav
For the past 20 years I have been building digital products from the ground up.
Right now I'm Co-Founder and CTO of Southern Lights, where we build decision intelligence tools for clean energy projects. We help developers make better investment decisions by turning volatility and uncertainty into clarity.
I've been in the startup space for a long time. Started companies, built products, failed, learned. These days I know what matters and what doesn't. I can build things quickly when needed—from the first line of code to the final design.
I leverage modern tools—LLMs, agents, automation—to maximize efficiency. Some I build myself, others I adapt to fit my workflow. The goal is always the same: build what's needed, ship faster, iterate smarter.
Some things I've built: co-built Afloat, a service to help freelancers manage their finances with less anxiety. Led infrastructure and team rework as CTO at Contentor. Founded Mynewsflash to reshape the Nordic news landscape.
I love to write and create. I have co-written and directed a horror short film called RO, which made the rounds on international film festivals.
I advise founders who lack a technical co-founder or CTO—helping them make smarter technical decisions and accelerate their startups. If you're building something interesting, and let's connect the dots.
