Primerus is the first AI system that builds and runs the entire digital presence for businesses (SMEs) in regulated industries, starting with the €2B+ DACH aesthetics market. Unlike generic marketing tools, our system is built around the legal and compliance guardrails (HWG, GDPR) that these industries require. We already have 10+ paying customers and €100k ARR after 8 months, fully bootstrapped.

Machine Learning & Artificial Intelligence
Today, Primerus combines AI-driven content generation, brand and website creation, and automated marketing across SEO, social, and customer communication. The long-term architecture is a fully autonomous agentic system: a business owner has one conversation, and the system independently generates, operates, and continuously optimizes their complete digital presence - brand, website, virtual twins, and AI communication agents. The core technical challenge is building reliable multi-agent orchestration with a compliance layer that enforces industry-specific rules at execution time. This is where I'm looking for a co-founder to take the lead.

About me
Julien Lüssem
Three-time startup founder and product strategist, currently building Primerus - an AI company that's already at €100k ARR with 10+ paying customers after 8 months, fully bootstrapped. My background: 7+ years in product strategy and digital transformation at Accenture and OliverWyman, leading 10+ cross-functional teams across beauty, finance, retail, digital assets, and the public sector in markets from Germany to the US and the UAE. Before that, I co-founded three startups, two backed by accelerators with 100k–600k in funding. Currently completing my Master's at WHU. With Primerus, I've proven the hardest part: real customers paying real money in a market I understand deeply. I bring the domain expertise, the go-to-market engine, and the traction. Now I'm looking for a technical co-founder to own the autonomous AI architecture and build this into a category-defining company. What drives me: building systems that make an entire industry's old way of working obsolete - starting with how premium businesses grow online.
Advanced Technologies (AI, ML, Blockchain)
Flexibility (Remote and on-site)
I'm not a first-time founder with just an idea. I've co-founded three startups (two of them backed by accelerators with 100k–600k in funding), led 10+ product teams at Accenture and Oliver Wyman across beauty, finance, retail, and digital assets, and I'm currently doing my Master's in Management at WHU. I know how to build a product, raise capital, and go to market. With Primerus, I've already proven the hardest part: real customers paying real money in a niche I understand deeply. What I bring is domain expertise, a sharp go-to-market engine, and existing traction. What I'm looking for is the technical partner to build the autonomous engine that makes this a category-defining company.
I'm looking for a technical co-founder (CTO) who wants to own the AI architecture of a company that already works. The ideal partner is deep in AI engineering - LLMs, multi-agent systems, orchestration and excited by hard problems, not just wiring tools together. You think in systems, you care about building something autonomous and reliable, and you want the technical vision to be yours, not handed to you. Beyond the skills: I'm looking for someone who wants to build for the long run. Someone who shares the ambition to go from a strong niche (DACH aesthetics) to a category-defining platform across regulated industries and who values honesty, speed, and real ownership over titles.
