Id4 Ventures

Id4 Ventures is a founder-led early-stage investment firm exclusively backing deep tech startups at pre-seed and seed stages, founded in 2017 by Herve Cuviliez and Ivan Petrovic and based in Luxembourg and Paris. The firm raised a EUR 16 million pre-seed fund in 2023 with initial check sizes of EUR 200,000 to EUR 500,000. Beyond direct investment, Id4 leverages its LP network to mobilize multi-million dollar special purpose vehicles that bridge funding gaps between pre-seed and larger institutional rounds. The firm also participates in the European ecosystem as an LP in top Series A-plus venture funds. Id4 leads rounds at pre-seed and seed stages across a portfolio of 38 companies spanning 13 European countries plus the US. The portfolio covers AI and machine learning, agritech, data, e-commerce, edtech, fintech, gaming, healthtech, logistics, robotics, SaaS, security, space tech, and sustainability. Notable portfolio companies include Gensyn (AI infrastructure for distributed computing), Orbital Paradigm (Madrid space tech firm building reusable orbital re-entry capsules, backed with EUR 470,000 from Id4), ThinkSono (medical AI for diagnostics), Reach Industries, and AYES (acquired by Synapse ITS in July 2025 as the most recent exit). The portfolio has seen 4 acquisitions in total. Id4's investment philosophy is built on conviction over consensus — betting on breakthroughs rather than hype cycles, and taking a long-term view on foundational deep tech research transitioning into commercial products. The three-partner team works closely with founders to accelerate technical validation, customer discovery, and the transition from laboratory to market, with particular expertise in European deep tech ecosystems.
