Congratulations to the @GeneralMedicine team on the $120M Series B led by @a16z. Proud to have incubated and backed the company from the beginning, and excited to have @tjparker leading its next phase of growth.
General Medicine has raised a $120M Series B led by @a16z. We're using it to build the healthcare store.
The only way healthcare will work is to make the customer the most powerful participant in the system. And the only way to do that is to let them shop.
Here’s why healthcare needs a store, and what we had to build to make it possible:

I do not support pacing frontier models. If I am going to die at the hands of killer AI, I want it to be American, not Chinese. Buy American, Die American.

ex Head of Product at Plaid announced a $46 million Series A.
Is it fintech!?
No. It's energy...but Baker (@bashogry) argues its more related than you might think.
Plaid connected its customers to the financial system. Light is building the platform to let any company become a power company.
We get into what that means, who the customers are and the "why now".
Energy is an infinite market, it's changing faster than it has in a generation.
Here is Baker's take on why this creates an opportunity for a new platform.
If you aren't paying attention to energy, you should be. Understanding what Light is doing is a great place to start!
my interview w/ long time friend and now founder Baker Shogry...enjoy!
Thrilled to announce Light's $46M Series A, led by @matrixvc ⚡️
Light is a fully regulated electricity provider that lets any company launch embeddable, programmable, and customizable energy products for their customers.
100% of new electricity brands entering the Texas market in 2026 launched on Light and revenue is up >10x. The rest of the country is next.
I’m excited to join the board and work with Baker, Adam, and team!

The Context Acquisition Company (CAC).
We are a holding company acquiring services firms for their tokens in order to build domain specific agents/ models to deploy into our platform businesses and beyond.
There's $1T hidden in the computers. We're gonna get it out.
"Man is the lowest-cost, 150-pound, nonlinear, all-purpose computer system which can be mass-produced by unskilled labor." (NASA, 1965)
Every job is an OODA loop. AI doesn't replace the loop, but unbundles it into sub-functions.
The most valuable ones are irreducibly human, and the smart companies are building for rather than against the 150-pound computer.
Here’s how:
