Technical Co-Founder | AI Engineer @ Brinna AI

Stockholm | Equity | Co-Founder Role

Description \

Brinna AI has spent the last year tackling one of the most expensive and recurring headaches in the startup world: the "design-and-decay" cycle of branding. Typically, organizations hire agencies to design assets that eventually become obsolete, complex, or disconnected from market reality. This cycle forces companies into periodic, costly, and disruptive re-brands.

After countless interviews with founders , working directly with enterprise clients , and iterating on multiple MVPs , we’ve landed on a concept to make "brand intelligence" accessible to everyone—not just the top 5% of companies that can currently afford to it.

We're looking for a technical partner who is as excited as us about what's possible with the current state of AI. It’s much more fun to build together, and we’re ready to find the right person who will help us build the engine to power this.

The goal

Democratize branding intelligence for the new era of business. To leverage human creativity, we build the infrastructure that integrates constant feedback loops and context to make better branding decisions.

The plan

Currently there is interest in the product and potential design partners. We will apply to Business Lab together in May. The go-to-market and distribution plans are already somewhat complete, but requires a demo to understand exact positioning.

What’s already in place

Market Validation: Extensive interviews with founders and startup hubs completed.

Proven Concept: Final concept for the agile branding ecosystem reached as of April 2026.

Strategic Roadmap: Clear path from agency integration to startup assistance and enterprise compliance.

Strategic Partnership: This project was initially launched as part of trebl's Al Venture Studio, and has continued support from them for investor relations, industry contacts, co-working and general advisory.

About the founder

The current founder and CEO is an SSE alumni and has lived in many countries. He has built many startups and learned a lot along the way. He is driven by problems deemed "too complex" to solve, as he have often found that creative thinking is the main limiting factor. In his free-time he enjoys hiking and mechanical projects like building bikes and restoring boats.

Who you are

You are driven by the possibilities presented by agentic workflows and extensive data gathering. You’re down-to-earth, leadership-oriented, and prefer collaboration over working in a silo. If you have startup experience and some "lessons learned" under your belt, even better, as we can combine our shared learnings in order to make rock-solid decisions.

The deal

Equity: 20-30% (open to discussion) with vesting.

Location: Stockholm, Helio Slottsbacken (co-working)

Role: CTO and Co-Founder. You will have a direct influence on the product, capital deployment, and the company’s evolution from day 1.


If you’re ready to build the platform that makes brands iconic through intelligence, let’s talk.
