WHU Management Master candidate and three-time startup founder with 7+ years in product strategy at Accenture and Oliver Wyman. I'm building Primerus, the AI system that builds and runs the entire digital presence for businesses in regulated industries (SMEs). Here's what makes it work: most marketing tools hand you a dashboard and leave you to figure it out. Primerus is the opposite. Our AI generates, operates, and continuously optimizes everything - brand, website, content, SEO/GEO, social, virtual twins, and customer communication - autonomously. The owner focuses on their craft; the system grows their brand in the background. We started in the €2B+ DACH aesthetics market, where trust and compliance decide everything. In 8 months, fully bootstrapped, we've reached €100k ARR with 10+ paying customers. The wedge is proven. IN the long run, we scale across every regulated industry where reputation is the product. I bring the domain expertise, the go-to-market engine, and real traction. What I'm looking for is a technical co-founder to own the autonomous AI architecture and build this into a category-defining company with me.

CordiVivo ist Pre-CE. Ein Solo-Gründer mit klinischer und medizininformatischer Doppelqualifikation hat das Konzept, die regulatorische Strategie und einen funktionsfähigen technischen Prototypen aufgesetzt. Was fehlt, ist ein zweiter Gründer, der die technische Verantwortung übernimmt und die Plattform von Pre-CE zu MDR-Klasse-IIa-zertifizierter Software führt — als CTO, als Mitgesellschafter, als Partner auf Augenhöhe. Das ist keine Anstellung. Es ist eine unternehmerische Mitgründung mit echtem Equity-Anteil, vollem Risiko und voller Gestaltungsmacht in technischen und strategischen Fragen. Deine Verantwortung Du übernimmst die technische Führung des Unternehmens — Architektur, Tech-Roadmap, Hiring des Engineering-Teams, Sicherstellung der Konformität mit IEC 62304 und MDR. Du gestaltest gemeinsam mit dem CEO/CMTO die Produktstrategie, vertrittst die technische Seite gegenüber Benannter Stelle, Pilotkliniken und Investoren. Du baust und führst das Engineering-Team auf, wenn die Finanzierung steht. Parallel bringst du dich in die Vermarktungsstrategie ein — nicht als Marketing-Lead, aber mit ausreichend Verständnis für Produkt-Positionierung, Go-to-Market und digitale Sichtbarkeit, um produktstrategische Entscheidungen mitzutragen.

I am looking for a technical co-founder with strong full-stack web development experience to help build the MVP and take ownership of the product’s technical architecture. The ideal co-founder should be able to design and develop a scalable web platform with user authentication, role-based dashboards for Teachers and Students, service listings, order/booking workflows, messaging, payments, admin tools, and AI-assisted features such as paper upload, PDF Q&A, service generation, recommendation, and quality moderation. Hard requirements: hands-on full-stack web development experience; backend experience with Django, Django REST Framework, FastAPI, Node.js, or similar; frontend experience with React, Next.js, Vue, or similar; database design experience with PostgreSQL or MySQL; REST API development; authentication and authorization; Git/GitHub; deployment experience using Docker, VPS, cloud platforms, or similar; and ability to build an MVP independently. Payment integration experience with Stripe, Stripe Connect, PayPal, or marketplace-style payment systems is strongly preferred. Contact: m.shoaib.0591@gmail.com

I am an international student, and I know how hard it is to find an apartment in big German cities. You have to scroll through hundreds if not thousands of inactive offers, you could not reach the landlord through the platform, or someone tried to scam you. At our apartment search platform, we plan to create a safe space, where the apartment seekers and landlords can match each other in a more transparent, secure, and easy way. That is why our apartment search platform would be a safe place for housing-seekers and landlords, where they can interact and deal with real people, while finding a suitable match in a quicker and easier way. The platform would offer a wide range of search tools, active communication and account management system and ability to check an apartment without you need to be there.
