Big Pi VenturesCheck size: €0.5M-€30M across Big Pi's family of funds, from seed and early stage through growth; this is a firm-level range.
Guy brings a founder-operator lens to Big Pi's multi-stage technology strategy. He is best matched with technically differentiated companies that can turn defensible IP into global products, especially where AI, software, or automation can create a durable competitive advantage and where his experience scaling businesses across many markets is useful.
Visionary technical founders with a well-rounded team, a large international market, defensible technology or unique IP, and a credible plan to translate an invention into a useful, scalable commercial product.
No clear pass criteria are available yet. Treat this as unknown until Kit finds direct evidence.
Lead with the hard technical or product insight, show why it creates a defensible moat, quantify the international market, and demonstrate that the team spans both product innovation and business development. For later-stage opportunities, include concrete evidence that the platform and operations scale; identify where Guy's founder and international go-to-market experience can help.
Pair technical differentiation with proof that the team can commercialize it across markets: product-market clarity, business-development strength, and operational scalability matter alongside the invention.
Start with protected or uniquely skilled technology, then test whether it solves a large problem and can become a globally useful product with lasting competitive advantage.
