Do you want to be part of a deep tech startup that's changing how the world shops fashion?

We’re building Trendbook, a deep tech startup that makes it stupid simple to go from fashion inspiration to actually finding and buying the look. Think Shazam, but for clothes, powered by TBnet V1, our own AI model built in-house by our current technical co-founder, Hans-Christian (and no, it's not just another CLIP wrapper).

We’re now looking for another technical co-founder to join us early – someone who can help us shape the product, scale the tech, and own the build-out with real vision.

What We’ve Got So Far

• A working app with our own AI model (TBnet V1)

• Proven ability to develop vision retrieval models that outperform leading open-source benchmarks.

• Our first investment from an angel investor

• Early traction + product roadmap

• +1 mio. commissionable products from retailers/brands like ASOS, About You, Magasin, Boozt, Bestseller etc.

• A lean, ambitious founding team

Our Stack (so far)

• Python

• Fast API

• REST API

• Supabase

• AWS

• Qdrant

• Flutter

• Next.js

• … and about 400mg of caffeine (-;

You definitely don’t need to know all of this – just enough to jump in, ship fast, and learn what you don’t know.

You Might Be a Fit If...

• You’re not just technical - you’re hungry to build something big and lasting.

• You thrive on ownership, not just tasks - and want real skin in the game.

• You're full-stack-ish and can take an idea from a whiteboard to a working product - but even more, you’re the kind of person who learns fast, iterates hard, and never gets too precious about being right on the first try.

• You’re energized by the ups, downs, and everything in between - that’s where the real building happens.

• You’re ambitious, not in a LinkedIn-brag way - but in a "let’s build something that actually matters" way

• You're comfortable with early-stage chaos: moving fast, figuring things out as you go, and shipping without perfect answers.

What You’ll Get

• True co-founder equity - not just a small slice or stock options, but meaningful ownership and a real upside.

• A real partnership - not just a job. You’ll work alongside founders who value clarity, integrity, and momentum.

• A seat at the table - you’ll be a part of shaping the roadmap, the tech, the culture, and the company from the ground up.

• Office space at Frederiksberg (And most likely dependent on coffee - if you aren't already....)

• Creative and technical freedom - we trust builders to build, not to wait for permission.

• A chance to build something truly new, with great people and a big vision — and be part of the journey from day one.

We’re not looking for a CV. Just send us something that shows how you think or build – GitHub, Notion docs, past projects, whatever.

Send it to Gustav Brun or pick up the phone and call him at +45 53 86 26 03.

We look forward to hearing from you.
