Co-Founder & Chief Business Officer - FIDgate (renewable-energy deeptech · pre-seed · Berlin/Germany)
Renewable-energy developers make multi-million-euro investment decisions on the first project design that works - not the best one. FIDgate's engine co-optimises the design, dispatch and financing of utility-scale solar, wind and battery projects in a single pass, and surfaces the €8–15M of additional value on a 200MW project that today's tools leave on the table. The engine is real and validated , proven on live client projects, €50M+ in additional value identified across 600+ MW, paid engagements and signed LOIs. We're now turning that proven technology into a SaaS platform, launching our first pilots, and raising our first external round. I'm the founder - technical and product. I'm looking for the commercial other half: a co-founder who owns the path from pilot to recurring revenue, and helps me build a company ( not just a sales pipeline). You'll own the commercial future of FIDgate: enterprise sales into developers, IPPs and utilities; the pilot-to-subscription conversion engine; strategic partnerships; customer success; and - with me - the fundraise, the investor relationships, and the commercial organisation we build together. You're not a quota-carrying salesperson waiting for leads, and not a COO who wants to run process. You've sold complex, high-value software to serious enterprise buyers, ideally in energy or an adjacent technical field. You can learn a genuinely deep AI/deeptech product and make a sceptical, technically literate buyer believe it. You've built commercial motion from near-zero, you're at home in the ambiguity of pre-revenue, and you think like a founder - because you want to be one. On offer: a real co-founder seat and meaningful equity; a validated deeptech product in a €2.2B European market growing double digits; and the chance to build the commercial engine of a company at the exact moment it goes from "it works" to "it scales." If this is you - or you know exactly who it is - let's talk 😀jmr@fidgate.com

Searching for EXIST/BSS Cofounder: AI Virtual Try-On for Fashion Retail
Every online clothing purchase is a guess. Nearly a third of all fashion bought online gets returned, and almost half of those returns come down to one thing: not knowing how it would actually look or fit. How By letting customers see themselves wearing the garment, in their own size, before they buy. One photo, seconds, not a size chart or a guess. What Jora is an AI virtual try-on platform for fashion retailers. Customers preview any garment on their own body in real time, in-store on a kiosk or online through a store's website. Currently live with a working demo and early market validation. I'm searching for a co-founder in tech to apply for EXIST/BSS non-dilutive funding together. I'm Raheel, founder with a background in communication design and four years in brand and product design. I've built Jora's full working product, kiosk interface, and landing page myself using AI-assisted development. I know how to build a product people connect with emotionally, but not how to own the deep technical architecture right. ——————————————————————————————————————————- I'm Raheel, founder with a background in communication design and four years in brand and product design.

Cofounder (m/f/d) with pedagogy expertise for EdTech wanted
Children consume AI. We want them to create with it. With the digital game construction kit, children between 8 and 12 years old develop their own game idea: an AI-guided dialogue helps them structure their ideas, and at the end, a real, playable browser game is created. The child gets something real. The parents get meaningful screen time. The game construction kit is the entry point to a larger vision: a supplementary educational format that teaches children to pursue their own ideas in a structured way – something that often lacks space and time in everyday school life. The Team: Two female PhD scientists with experience in educational policy and expertise in educational promotion, institutions, and networks. Who we are looking for: A co-founder with pedagogical expertise – curriculum development, impact measurement, access to schools and educational institutions. Two ways in: Co-founder: operational, shares, flexible time model possible Master's thesis: research cooperation e.g. on impact measurement or learning design, with a clear perspective on the co-founder role
