Convexity Ventures

Convexity Ventures is a Luxembourg-based private angel network founded in 2018, investing in pre-seed and seed-stage ventures and digital assets. The firm operates at the very earliest end of the funding spectrum, writing checks of $5,000 to $50,000 into ideas and early-stage companies in AI, web3, and software applications. Operating countries span Luxembourg, Germany, France, the Netherlands, the United Kingdom, and the United States, reflecting a pan-European and transatlantic investment posture. As an angel network rather than an institutional fund, Convexity focuses on unlocking value in nascent ventures before traditional VC capital is available or appropriate. The firm's approach involves partnering with legacy institutions and emerging ventures to align incentives at the earliest possible stage, with a thesis that early engagement creates structural advantages that are difficult to replicate at later rounds. Convexity Ventures occupies the micro-check pre-seed tier, where capital deployment decisions are made quickly and portfolio construction relies on volume and diversity rather than large concentrated positions. For founders at the idea or patent stage who need small but credible early capital alongside domain guidance, the firm's European and transatlantic presence and willingness to move at the earliest stages make it a relevant partner in the founding moment.
