Constantin Schreiber
Founder
Dropped out of college to build Blair (YC S19) where we raised a +100M to build income-based financing solutions for students in the US. At Blair, I led the engineering team to build audit-proof software that moved millions of dollars in student funds on a weekly basis. Two fun facts about me: I built autonomous drones for Porsche and was mining crypto to pay for college (and other things).
