Mosaic Ventures is a European venture capital fund built by partners with Silicon Valley-style startup and investing backgrounds who focus specifically on European Series A rounds, typically $3–10M, that come right after a startup starts finding product-market fit; the firm operates as a small, flat partnership by design, was notably early to blockchain investing, and follows named investment themes like machine intelligence and future of money rather than generic categories. It aims to back Europe's most ambitious founders, using an approach centered on founder-market fit and rigorous founder writing, while paying particular attention to Northern Europe and to businesses with strong data or network effects.
