I’m building Ferne, a travel discovery platform that helps users discover places and plan vacations, and I’m looking for a co-founder strong in product thinking, UX, design/branding or business development who wants to shape the product and company with me from an early stage. Instead of starting with a destination, Ferne learns what kind of trip a user is looking for and recommends regions that fit their preferences, budget and constraints. I’m a software engineer and currently building the MVP myself. The technical foundation and product concept are already well underway. Of course you don’t need to cover all of these areas. The most important thing is taking ownership and being excited about the project. If you can see yourself in this position, I’d love to get in touch with you and meet over a coffee or tea.

I am looking for a technically strong and entrepreneurial-minded Co-Founder to build SENVOR with me. Start with 5-10 hrs per week. SENVOR aims to develop an innovative and scalable business model where AI, software and intelligent data analysis create real value for companies. I bring 20+ years of experience in national and international sales and business development for mid-sized industrial companies, particularly in the electrical and energy sectors. My strengths include sales, business development, customer relationships, market development and a strong understanding of industrial companies and their needs. I am looking for a partner with expertise in AI, software development, web development and/or building digital products. You should not only be technically skilled, but also have the entrepreneurial mindset and ambition to build a company from the ground up. This is not a freelancer or contractor position. I am specifically looking for a Co-Founder and long-term business partner with an equity stake in the company. The vision is there. Now I want to turn it into a real product, a strong business model and a scalable company together with the right partner. Technology. Business. Growth. Let’s build it together.

AI is transforming businesses — but adopting it inside real companies is still hard. Companies need specialized AI / FDE talent, but building these teams is expensive, and the best engineers are distributed globally. At the same time, AI transformation often requires companies to expose sensitive business data — making trust, privacy and security a major barrier. Anchorstate is building the trust bridge between enterprises and the global AI engineering ecosystem. We help companies adopt AI on their real business data, while providing the infrastructure and trusted process needed to make that transformation reliable and secure. Our first open-source product, GMR, is one building block toward this vision: helping AI systems stay grounded in real-world signals. We are currently based in Germany and looking for a European co-founder to build the market with us. We are especially interested in someone with experience in B2B, enterprise software, consulting, digital transformation, or startups, who understands European businesses and wants to build something from zero. Our long-term mission: make AI transformation trustworthy, wherever the AI talent and the enterprise are. my email: hezongmingdt@gmail.com

I'm about to finish my mathematics master at RWTH and I'm now exploring opportunities in the startup ecosystem. I bring excellence in Mathematical Optimization and Operations Research as well as business experience from previous work in VC, startups, and adjecent areas and several uni courses (e.g. minor in BA and TRACE programme). I am not fixed to a specific industry but I previously focused in Energy. If you are currently working on an idea, looking for a co-founder, or know someone I should talk to, then please feel free to hit me up https://www.linkedin.com/in/luca-bast/

I am looking for a commercially minded co-founder who wants to build HexaWeaver with me from the pre-seed stage into a viable industrial software company. HexaWeaver is a deep-tech software project for multi-axis additive manufacturing. It develops intelligent slicing and machine-aware toolpath planning for complex 5-axis printing processes. The goal is to replace fragmented manual workflows with a system that considers non-planar layers, machine kinematics, reachability, collisions, and simulation data from the beginning. A working technical proof of concept already exists, together with a clear development roadmap. My own background lies in mechanical and aerospace engineering, industrial R&D, inspection robotics, additive manufacturing, and software development. I am therefore looking for someone who complements me by taking ownership of the commercial side of the venture. Your focus would include customer discovery, market validation, business model development, industrial partnerships, pilot-project acquisition, funding strategy, and grant or investment applications. You should feel comfortable speaking with machine manufacturers, research institutes, industrial R&D teams, and potential technology partners, and translating their needs into clear commercial and product priorities. Experience in industrial B2B sales, business development, startup financing, product management, or deep-tech commercialization would be especially valuable. Familiarity with additive manufacturing, robotics, industrial software, aerospace, energy, or mechanical engineering would be helpful, but you do not need to be an engineer. What matters more is curiosity, reliability, strategic thinking, clear communication, and the willingness to understand a complex technical product. I am not looking for an employee who simply executes a predefined plan. I am looking for a genuine partner who wants to challenge assumptions, share responsibility, and help shape the market, strategy, company structure, and product direction. The immediate goal is to identify strong pilot partners, validate the most valuable customer use cases, and develop a focused go-to-market strategy. The intended collaboration would be based on meaningful equity, shared ownership, and a transparent founder agreement.

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.

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
