Big Pi Ventures is a multi-stage technology investment platform anchored in Greece with a global remit, backing extraordinary entrepreneurs at every stage from seed to growth equity. The firm is 'tech-first'—not merely tech-enabled—requiring strong IP and defensible competitive advantages, with a substantial majority of investments in B2B businesses. Big Pi requires portfolio companies to have a meaningful connection to Greece (through operations, founders, or customers), leveraging the region's exceptional engineering talent and cost-effective operating hubs to build companies that serve international markets. Its early-stage funds (Big Pi I: €48m; Big Pi II: €70m) deploy €0.5–3m tickets at pre-seed and seed, while Big Pi Growth I (targeting €200m) deploys €7–20m+ tickets to supercharge European tech scale-ups bridging the gap between early-stage funding and late-stage/IPO capital.
Notable quotes
“Our approach is 'tech-first'—not just tech-enabled—meaning companies must have strong IP. What we consistently look for is technology that solves a significant, painful problem for a well-defined group of users who are willing to pay for a solution. And most importantly, at our early investment stage, we heavily back the founders themselves.”
“We are very excited to be joining the Vivante team and truly inspired by their vision to transform the management of chronic conditions. This is one of those rare investments where the financial upside goes hand in hand with the prospect of radically improving the lives of millions of people across the globe.”
“We're looking to invest in companies either in Greece or globally, but with some Greek presence at all times. We're doing early stage investment, so pre-seed but primarily seed … we want to be investing in technologies that have the potential to really disrupt and change the market either at the regional or at the global scale.”
