Brothers and co-founders Karan and Neel Kunjur started **K2 Space** on a contrarian bet. When the entire satellite industry was building smaller satellites, K2 built larger and more powerful satellites.

In space, everything comes down to power, and power scales with size. More size means power, which means more capability to run experiments and missions that weren’t doable on smaller buses. Neel Kunjur says it best: 

> “We’re vastly underestimating our own capabilities of what we can do in space. We need to think bigger, not smaller.” 

That contrarian bet became real when K2 launched Gravitas — the 20kW satellite is one of the highest-powered spacecraft ever built. 

This is the story of how K2 is making the impossible, possible.
