At NcodiN, we are redefining how chips communicate. We unlock a new era of ultra-fast, energy-efficient optical interconnects, powered by a breakthrough technology: the world’s smallest laser integrated on silicon. This means AI hardware that is smaller, faster and dramatically more efficient, enabling limitless scalability while consuming less power. In a world that demands speed, optical interconnects are the express lanes of the future, built for AI’s full potential. The shift is inevitable, and at NcodiN we are making it happen.

OPRTRS is an operator-led investment platform backing founders at the very beginning. We’re powered by 170+ top tech operators who know how to ship, scale, and survive the early chaos. We believe operators build the best companies and support each other better than any boardroom ever could. So we’ve turned that conviction into a community: a network of current and former leaders from OpenAI, Palantir, Stripe, Mistral AI, Qonto, Revolut, Datadog, Doctolib, Hugging Face, Wiz, Rippling, Backmarket, and dozens more. We invest €200k in the first rounds and surround founders with hands-on operator support: GTM, product, hiring, internationalization, fundraising. No theatre, no fluff. Just people who’ve done the work. Our core team: Christophe Raynaud (Cofounder @ ISAI) Noé Gersanois (ex-Partner @ Raise) Younès Rharbaoui (ex-Partner @ The Family) Supported by Renaud Boutet (SVP Product @ Datadog) as Venture Partner. We’re backed by great partners: Leblon Capital, Kima Ventures, Motier Ventures, Financière Saint-James - who trust us to spot and support the next generation of breakout operators-turned-founders. Since launching in 2024, we’ve already backed 15 ambitious teams, from deep tech to AI to industrial innovation. What matters to us isn’t the sector it’s the ambition and the builders behind it. If you’re an operator making the leap, or a founder who values hands-on expertise over PowerPoints, we’d love to meet you: hello@oprtrs.club

At Kinisi, we dont sell science fiction. We build robots that actually get work done. By equipping practical, wheeled-base humanoids with the latest LLM intelligence, we make them adaptable to any problem in any warehouse. Unlike wobbly bipeds, our bots are smart, speedy, scalable, and safe to work alongside humans so we can solve todays labor shortages. We’re founded by Bren Pierce, who shipped over 25,000 robots at his previous startups, and Ed Lando, who founded unicorn startups that have raised hundreds of millions. Kinisi is pioneering the future of physical intelligence where we dont mimic human biology — we outperform it. If you ship fast and want to see your work in the real world, not just in demo videos, reach out careers@kinisi.com

Project Europe aims to drive European innovation. It does not follow any existing political movements and will remain independent of political parties and ideologies. A core pillar of Project Europe is to encourage the next generation to take greater risks and make entrepreneurship a worthwhile endeavour in Europe. Project Europe Founders can move their businesses outside of Europe, or build a remote organisation across continents; our aim is to nurture the creation of tech companies with European roots. The vision for Project Europe is that it becomes an independent organisation promoting entrepreneurship at the grassroots level with more founders and partners contributing for future cohorts.

Huskeys is pioneering a new category: Edge Security Management (ESM). We’ve built an agentic AI layer across the entire edge security stack- unifying CDN-WAF-Infra-App, into a single, continuously adaptive system. For years, organizations have struggled with a painful reality: WAFs are powerful, but complex, noisy, and resource-intensive. Managing them is difficult, outcomes are inconsistent, and the operational burden is high. We gave up on trying to make it effective. Huskeys solves this. Our AI continuously assesses, adapts, and orchestrates rules, policies, and configurations - optimizing for both security and business outcomes. The result: your existing WAF becomes effective, transparent, and economically impactful. Less noise. Fewer false positives. Reduced manual overhead. And significant cost savings - often in the millions. Huskeys transforms edge security from a fragmented, reactive challenge into a unified, intelligent, and outcome-driven system. We are Huskeys and we clear the WAF way.
