How to start a VC-backed startup Golang Warsaw #59 Jacek Migdal, July 10, 2024Jacek @ CEO and co-founder of Quesma. Database gateway. Seed startup with $2.5Mln funding. Previous, 10 years at Sumo that there are still uncharted frontiers to explore ● Profit: ○ Create value ○ Capture with moatHow VC works? 1. Raise money from rich (called Limited Partners) 2. Invest in promising young companies: Few will produce 10+ times return. 3. Sell them, return profit to LPs.VC track record 1. Almost all new big companies were VC-funded. 2. The biggest driver of innovation. 3. A major source of wealth
