At BADideas.fund, we aspire to be the kind of investors we wanted when we were building our startups. We invest €50-€250K tickets in early-stage startups from CEE with global ambitions. BADideas.fund is led by experienced entrepreneurs who have walked the startup building path, have raised funds from investors and can help founders navigate around obstacles they encounter along the way. Among BADideas.fund members are founders and operators, who’ve been building such companies as Vimeo ($450M funding), Printify ($54M), Pandadoc ($51M), Pipedrive ($90M), Bolt ($1.3B funding), Apollo.io ($151M), Bird ($783M funding), Shopify ($122M), Whimsical ($30M), Lokalise ($56M), Deel ($679M), Printful ($130M), Twilio ($614M), Veriff ($192.3M), Wise ($1.3B funding).
