Hello! I'm working on a concept for a VR tool that lets set designers create rooms directly in 3D – at real scale, spatially comprehensible, and easier to present. To get this going, I'm currently looking for people with a tech or strategic background who are interested in developing the project together. Ideally developers and sales people who could see themselves as co-founders :) This year I received an EXIST-Women scholarship for this project, and as a next step I'd like to apply for further funding through the EXIST Programme with a team to bring the idea to life. Let's chat if it sounds like something for you! hello@ksuchecka.com https://ksuchecka.com/vr/

In the art world, contacts mostly decide who gets seen, and commission-based professional representation leads to most artists carrying the entire business side of their career alone. Amadeus is an autonomous AI agent that takes exactly that off their plate. As a freemium SaaS it covers a visual artist's career in five modules: Admin and Finance, Marketing, Sales, Strategy and Opportunities. It is (so far) the first vertical AI agent built for visual art. The first module, Opportunities, is already running as a working prototype, built on Python, LLMs and an agent architecture with a quality layer. I'm currently getting first test-users. I'm searching for a technical co-founder (CTO) to own the technical architecture, turn the prototype into a platform, and apply for the Berliner Startup Stipendium (BSS) with me. About me My name is Victoria, I hold a MSc. in Management and 2 years experience in the art market in Paris and Berlin, working with emerging artists as well as the top 1% of the market. I know the dynamics of the art market well, believe strongly in the arts as a fundamental human good as well as in autonomy - so I needed to change accessibility to the arts! I am currently a solo-founder, working full-time on the agent and built the working prototype with Claude Code. Who I'm looking for Cares about the arts and is excited about changing the art market and its accessibility with AI Thinks big Strong with AI applications, ideally LLMs and agents Solid backend foundation, for example Python Enjoys building from zero to one and owning the technical calls What I offer A real co-founder role with equity The chance to build the first AI agent for visual art from the ground up A running prototype with a curated database Direct access to the target group through my network in the art world An ambitious and fun co-founder, eager to make change happen ;) Currently bootstrapped, so this is not a salaried role yet. Berlin is ideal, Vienna or remote works too, full-time. Interested, or know someone who could be a fit? I'm excited to meet you!

About us We are an early stage AI Legal Startup trying to make product compliance easier. Right now, it's messy, complicated and barely understood by anyone. We are building the backbone of automated legal advice for product compliance. And we are growing! We just got the EXIST grant, and have a stipend for a 3rd person, who wants to grow with us! Until now, it’s just been the two of us: a US engineer and a German lawyer, who have known each other for like a decade.

We are looking for someone with verifiable B2B sales experience for products or services that require explanation, a business sense, and solid numbers. You take responsibility, act even under uncertainty, and are looking for a long-term full-time co-founding role. German business fluent, English very good. Product and initial practical experience are there. Location Berlin, hybrid collaboration, start immediately.

Germany has around 130,000 bridges and a growing share of them are in bad shape. The Carolabrücke in Dresden collapsed in 2024. The Rheinbrücke Bonn-Nord was closed completely in June 2026. Every one of these bridges has to be inspected under DIN 1076: a full inspection every 6 years, a simple one every 3, a visual check every year. Today that means scaffolding, rope access, and often a clipboard and an engineer's handwritten note. The results aren't comparable between inspections. Nobody can tell you whether that crack got wider since 2021. We're fixing that with a drone, a modular sensor payload (LiDAR, RGB, later ultrasound and thermal), and software that turns the flight into a digital twin with the defects marked on it. Your responsibilities Lead AI Development: Design, build, and deploy computer vision and spatial/temporal models for automated damage detection on infrastructure Data Pipeline Development: Create efficient end-to-end data processing pipelines for automated multi-sensor analysis and edge/cloud model training. Technical Strategy: Define our long-term software architecture Software Layer  The comparison: same bridge, three years apart. What changed, and by how much. The digital twin: point cloud in, something an inspection engineer can click through, out. Must-haves University degree in Computer Science (or a related field) with practical experience in Machine Learning and Computer Vision algorithms. Possess a founder mindset and readiness to take full technical ownership. Hands-on experience writing clean, deployable code and solving complex technical edge cases. Built and shipped a real backend. APIs, a database, storage, a pipeline that chews through large data without falling over. Helpful, not required: point clouds, LiDAR or photogrammetry. Jetson. Anything from construction, drones or civil engineering. German. The deal Equal share of the company. A third each, with vesting. No salary until we secured grants.  Honest about the timing: between now and the EXIST stipend (roughly Q1 2027) we're asking for around 10 to 20 hours a week next to your job, unpaid, for equity. From the stipend onwards, full time. You need to qualify for EXIST: You live in Germany.  Work from wherever. We'd like you to be open to moving when EXIST starts, most likely Munich or Berlin. Interested? Send whatever shows the work best: a repo, a paper, a project you'd tell a friend about. Tell us the hardest thing you've shipped and what broke.
