@FoundationAlloy is redefining what’s possible in metals production, creating a new paradigm in alloy design, development, and performance. Foundation’s tech enables solid-state processing without melting: they can engineer microstructures and materials performance otherwise impossible with conventional melt processing. Their integrated design-test-analyze platform significantly speeds the time to market for new alloys. We’re thrilled to be leading their Series A!
Manufacturing alloys now run 900-day lead times. That's because we're still making metal by melting it, which humans have done since the Bronze Age. Engineering alloys are inside everything advanced: jet engines, rockets, energy infrastructure, precision tools. The traditional

Congratulations to the whole @SpaceX crew - your ambition and engineering excellence continue to inspire. Ad Astra! 💫
Let’s go @endurancegeo!
Endurance is proud to announce our $54M Series A, led by @foundersfund, to develop subsea geothermal energy. We're building mass-manufacturable and mass-deployable generators to access terawatts of low cost, clean, baseload power.
Given the space-faring inspiration for our firm name at @VoyagerVC, I’m particularly excited to have led the Series A for @NewOrbitSpace as they pioneer Very Low Earth Orbit. Top team building at planetary scale - and beyond. 🛰️
There's a sliver of space -- 200 to 300 km up -- that's been empty for sixty years. Not because nobody wanted it, but because nothing could survive there. The closer a satellite flies to Earth, the more it can do and the less it costs. The catch is atmospheric drag: strong
The perfect context for wide-open conversations
The Voyager team headed to Yosemite last month for our annual offsite. A few days in one of the most beautiful places in the world -- hiking, rafting, sunburning, and spending time together. So much momentum right now in energy and reindustrialization - we're excited for the

“You can see the surface of the Moon…we just went sci-fi.” On flight day seven, images from our @NASAArtemis II crew amazed, turning science fiction to reality. From the lunar far side to a solar eclipse from the Moon, the views are EVERYTHING. No pressure to pick a favorite.
