APRIL 25
In April 2025, Sebastian reconnected with a former Amazon mentor, Gur Kimchi, over lunch in Seattle’s Capitol Hill. He had been evaluating various startup concepts and wanted to run them by Gur, who is an advisor at an aerospace-focused VC. One of Gur’s many superpowers is “Think Big.” He thinks in decades, not quarters and arcs of civilizations, not products. Gur and Sebastian spent the afternoon diving into space technology, national security, and the future of national conflict, specifically addressing this question: What technology building blocks exist today that we can combine with a big problem to solve to build a massively impactful and necessary company within a decade. Our discussion converged on the biggest, most necessary, and what would have been foolish to ignore concept. That concept became Wardstone.
JULY 25
Sebastian spent a few months working on physics based simulations to evaluate satellite capabilities and constellation designs along with new interceptor concepts. In July 2025, Sebastian responded to a Request for Information from the US Space Force for novel concepts for the Golden Dome. He was invited to the Los Angeles Air Force based for the Golden Dome industry days.
Sebastian grabbed his younger brother, flew down to LA, and they sat in a room full of big Aerospace Primes and Military leaders. The Space Force laid out their development and funding plans for the Golden Dome. It was an amazing alignment between what Sebastian had been working on and what the nation needed.

Within the next month, they were accepted into Y-Combinator, Tobias quit his job, Sebastian moved down to SF and they began building out Wardstone.
