Overview

Seaflight Technologies has developed a new form of Aerodynamic Flow Control for electrified aircraft that increases range and payload by 30%. That's the same performance improvement you'd get from hopping in a DeLorean to 2035 and coming back with batteries from the future. But it's available today - our tech has been derisked by testing supported by the National Science Foundation, the US Air Force, and the Australian Government.

Our first product is a simple fixed-wing large cargo drone that is efficient enough to remove the "green penalty" currently associated with electric aviation. That's a step change from today's conventional platforms.

First generation electric aircraft are heavy, expensive, complicated, and limited in terms of range and payload. In the entire history of aviation, that's never been a winning formula. When everyone already has access to the same batteries, materials, and motors, what really makes the difference? The answer is revolutionary aerodynamics, but in a form factor that suits today's operations and manufacturing.

Beyond our own drone product line, we have partners across Aerospace helping incorporate our tech into their products. In the future, if you want to have the most efficient and cost-effective flying machine of any description, you'll need Seaflight's Flow Control inside.

Origins

Graham "Myself and Will Sutton built the first prototypes in our garages, this was before we even got into YC. Some bits of plane are still in there. We were obsessed with the idea that if you could make an electric plane just dramatically more efficient using aerodynamics, then you'd start to get the range that'll make it viable so much sooner than anyone expects. Then it'll take on that air of inevitability that happened with cars as soon as the Model S arrived"
