PRESS RELEASE — Sixteen finalists selected from more than 2,100 applications will present live at Constructor Start‘s fourth Demo Day on September 21 in Bremen, Germany, where the program’s investment decisions are made and announced live on stage. Constructor Capital invests $100,000 directly in each winning team, a confirmed $300,000 this year, in exchange for equity. Beyond that direct investment, finalists also gain access to further, potential funding through Constructor Start’s investor network of venture funds and business angels, bringing total available funding up to $1 million. The program’s picks already have a track record to back them: Demo Day alumni have raised more than $10 million in follow-on funding since last year’s cohort alone.
