We can do a random search through the founders of various unicorns. My first hit was Brian Chesky [1], one of the Airbnb founders. His parents were social workers. Stripe was founded by two brothers who were born in Limerick, Ireland. Maybe they were middle class in Limerick, but most likely not rich by global standards. They are now worth $3BN each [2]. Instacart was founded by Apoorva Mehta, who was born in India, and whose parents immigrated to Canada in 2000. Apoorva doesn't have a wikipedia page, but again, very likely his family was not rich. If you go through the wikipedia unicorn list [3], you'll find many founders that appear to be from middle or upper-middle class, but also many founders from lower-middle class as well.
