Investor Profile: Big Pi Ventures — Thesis, Cheque Size & How to Apply

Big Pi Ventures funding is for founders building technology that is genuinely hard to copy. For teams asking how to get funding from Big Pi Ventures, the test is plain: the Athens-based firm invests in founders working on proprietary technologies that solve big problems, centred on computer science, artificial intelligence, life sciences and climate technologies.

Thesis and investment focus

Big Pi Ventures is tech-first, not merely tech-enabled: portfolio companies must have strong intellectual property at the core of their value proposition. Its mission is to support exceptional founders with a connection to Greece, whether based there or Greeks abroad, and help them build world-class companies. It focuses more on technologies than industries.

Sectors, stages and cheque size

Big Pi Ventures invests mainly at pre-seed and seed stages, typically taking a lead investor role, and funded companies must have or build a substantial part of their operations in Greece. A meaningful Greece connection, through operations, founders or customers, is a threshold condition, not a preference. The firm highlights computer science, artificial intelligence, life sciences and climate technologies. A standard cheque size is not publicly disclosed in its own materials or partner interviews, so discuss round size directly with the team.

Fund size and track record

Big Pi Ventures was launched in 2018 by Marco Veremis, Alex Eleftheriadis and Aristos Doxiadis, in a wave of Greek funds enabled by European Investment Fund capital allocated in 2017. Big Pi 1 was a €48 million fund that made 23 investments. Big Pi 2 launched in 2023 as a €70 million fund, with seven investments by May 2025. The platform has since grown: its site announces Big Pi Growth I, the first tech growth equity fund out of Greece and Southeast Europe, with a first closing at €130 million, a targeted €200 million final closing, and total assets under management of about €250 million.

Notable portfolio

The Big Pi 1 portfolio includes Accusonus, an AI audio company acquired by Meta, Anodyne, a biotech company, and Intelligencia AI, an AI-driven drug development company. Those three names, confirmed in a partner interview, show the range: applied AI, life sciences and computational drug discovery, all with defensible technology at their core. The firm's partners take a very active role in supporting portfolio companies.

Partners and programmes

Big Pi Ventures was founded by Marco Veremis, Alex Eleftheriadis and Aristos Doxiadis, and partner Guy Krief has spoken publicly about its approach, including his role as president of La French Tech Athens. Its early funds were supported by the European Investment Fund and by EPAnEK, the operational programme for competitiveness and entrepreneurship, backing that helped accelerate the Greek technology ecosystem. No accelerator programme run by Big Pi Ventures itself could be verified.

How to apply for funding from Big Pi Ventures

Approach through bigpi.vc, where the firm presents itself as a partner and champion throughout the founder journey. Lead with the technology: what is proprietary, why it is hard to replicate, and what painful problem it solves for a well-defined group of users willing to pay. Be explicit about the Greece connection, whether operations, research teams, founders or customers, and about thinking internationally from day one, since the Greek market alone is rarely the primary target.
