About me
About me
I studied Political Science and Economics. My thesis explored how private space actors influence geopolitical power. That work pulled me into the space sector - and convinced me how much of our future will be shaped there. Spacebriefer sits at the intersection of policy, industry, and security. Each day, I share the most relevant space news in a compact brief, add deeper dives on key topics, and publish conversations with practitioners.
If you’re building, funding, regulating, or just trying to understand what’s happening in space, I hope this helps.
Drop by if any of this interests you.

Mission & Method
How the daily brief works
Spacebriefer is powered by a custom system I built to scan space news daily.
Sources
Hand-picked sources, built through research and conversations - brought together in one curated list, so the brief isn’t shaped by random or unreliable outlets.
Scan
An agent automatically scans each link in this list to flag fresh updates.
Summaries
The day’s key news is summarized and synced to this site - one headline and four bullet points per story.
Research
I also research independently to surface stories outside the usual sources, produce topic-specific deep dives, and continuously refine the source list.
