Happy Tuesday Brex Community,

Just got back from San Francisco, had a great few days hanging in SOMA and Dogpatch neighborhood primarily. The main focus of the trip was to meet some candidates IRL as we are continuing to hire at a rapid pace, our offices in SF and NYC are expanding quickly! On that note, I’m looking for to hire in SF, looking for someone who wants to be deeply entrenched with the VC and Founder community, job req here.

Secondly, I did want to check out the YC summer batch, which was 234 startups. I only got to see half of them present but there were some clear trends that I saw in those 115+ pitches. First thing that stood out if the number of defense, space, hardware and robotics startups to were in the batch, they had a large hanger when you got to meet all of them (see below). There were very little consumer, edtech and fintech startups in the batch, perhaps these are the contrarian sectors? Of the limited fintech startups that presented, there was a concentration of insurance companies, which was a surprise. Overall, it was both inspiring to see so much innovative ideas in one room and also brought a lot of optimism during a crazy week full of AI doomerism.

I visit SF every few months and things are clearly getting better in terms on activity, cleanliness and general positive vibez, it’s great to see the momentum and hope it continues. My hotel was near 4th and Market, which is convenient but can also be a bit sketchy sometimes, went for early 6am walk to the Ferry building to catch the sunrise and didn’t run into any odd situations. I’m bullish on SF & looking forward to my next visit.

Have a great week!

Ethos was one of the more interesting startups that presented at YC demo day. The TLDR is that they are looking to build solar panels on the moon.

Team - Brogan BamBrogan was employee #23 at SpaceX. He built the first Falcon and Dragon. Previously, he founded Hyperloop and Arrivo. Ross Centers is a lunar geologist from the Colorado School of Mines. He previously founded the Planetary Sunshade Institute.

Problem - There is infinite power in space. But rockets can’t carry enough solar panels. Rockets are the constraint.

Solution - Power in space must be made in space. Self replicating power and mass relieves the rocket constraint. The Moon is made of Silicon (and other useful atoms). Silicon makes solar panels (and compute). Solar panels make energy, to refine more silicon and power more compute.

Why now - Capital needs from Earth will diminish as self-replicating power and mass grows on the Moon. Moving up the Kardashev scale will be a matter of wattage and tonnage, not dollars. If you’re not early to self-replication, you’re too late.
