Solo GP of Wave Function Ventures, a $15M deep tech fund backing hardware founders at the earliest stage, sometimes pre-incorporation, across aerospace, defense, energy, robotics and infrastructure. Fund I reached its final close in October 2025 with nine investments made. At SpaceX he was the responsible engineer on the Falcon 9 aft thermal shield, the part that made the first hypersonic reentry of an orbital rocket, and first-stage reuse, possible. Before that he designed aircraft at Scaled Composites, including early sizing on Stratolaunch. He co-founded Talyn Air (YC W20), an electric VTOL cargo aircraft that reaches fixed-wing range by being caught mid-air by a winged drone, and sold it to Ampaire in 2023.
Jamie Gull is the founder and solo general partner of Wave Function Ventures, an early-stage deep tech fund for hardware founders. He was an engineer at Scaled Composites and SpaceX, and co-founded Talyn Air, which Ampaire acquired in 2023.
A deep tech fund that invests at the earliest stages, sometimes pre-incorporation, in aerospace, defense, energy, robotics and infrastructure. It announced the final close of its $15M Fund I on 3 October 2025, nine investments in. Its LPs are founders, engineers and high-net-worth individuals, plus funds of funds and large family offices.
He was the responsible engineer on the Falcon 9 aft thermal shield, the hardware at the base of the booster that enabled the first hypersonic reentry of an orbital rocket and the reuse of its first stage.
He joined as a design engineer, did the early sizing work on the aircraft that became Stratolaunch, and was one of five engineers on a 5,000 lb optionally manned aircraft.
The eVTOL company he co-founded with Evan Mucasey and took through Y Combinator's Winter 2020 batch. Talyn built long-range electric VTOL cargo aircraft: an electric fixed-wing aircraft caught mid-air by a custom winged drone, so it takes off and lands vertically without giving up fixed-wing range. Ampaire acquired it in 2023.
Deep tech hardware at pre-seed and seed, occasionally before a company is incorporated. The fund's sectors are aerospace, defense, energy, robotics and infrastructure.
