Spent a few energizing days at @reindsummit with @VenusAerospace. I left more convinced that the future of American security depends on the builders, funders, and policy makers in that room. It’s time to rebuild American industrial strength through innovation.

Another FIRST EVER by a @BoostVC founder! That is what Deep Tech is really about.
Today, Venus Aerospace made history. We completed the first-ever U.S. flight of a rotating detonation rocket engine — proving runway-based high-speed flight is possible. A huge thanks to our team, @Spaceport_NM, our investors, and U.S. government partners. Let’s keep moving
