I’ve got to remember to keep tissues in my purse. I’m prone to crying when I’m proud. I am a crier by nature and the experience of pride and awe is becoming distressingly common. Woe is me right?
My very early bet on Valar Atomics (Day 1145) is paying off years, if not decades, ahead of my expectations. Never did I expect arguably the hardest bet in my portfolio to be such a fast breakaway hit. And I owe it to an executive order from Donald Trump. Which is crazy.
As it turns out, if the government gets out of the way of talented people, nay, if it demands that our state institutions help them, the impossible becomes possible in shockingly short order. The reports of America’s death are greatly exaggerated.
Today in front of a crowd of hundreds of investors, employees, and family members, I watched a reactor that might not exist without my first check, power an Nvidea Blackwell chip.
In a demonstration rivaling the greats (Ballmer, Jobs) Isaiah brought up NuclearWebsite.com and asked the audience to load it with him.
“Oh no it’s not loading?!!?” What’s happening? Do we have any electricity on site? Quick someone run the GPUs to the nearest electricity! Go go we can’t disappointment all these people!
And then the Blackwell is rushed into the Ward250 reactor. In real time the chip is run to the control room, gets hooked up and boom the website loads.

The first entirely privately funded nuclear startup was critical, stable, producing electricity and powering state of the art silicon.
We actually did it. The mad lads and ladies of Valar Atomics swept ahead of the competition in a frenzied year of progress (Day 1510) from seed round and Ward Zero to producing electricity to power GPUs.
After a twenty four hour travel marathon to get from the Ionian in the Mediterranean to the southern Utah desert, being back at the Valar Atomics reactor facility for a demonstration of this magnitude felt surreal.
Just a few weeks ago (Day 1969) the reactor was days away from being shielded and then fueled. We’d driven down to see her before she was wrapped up in shielding.

Now not only has she gone critical (Day 1996) but I was able to walk into the running reactor room and see the live reactor for myself. The operator Ben (a former naval nuclear operator) seemed surprised and happy to see me. “Julie! Hi!” He exclaimed as me and the other early lead investors piled in for a tour.
I won’t lie it felt really cool that the team knows me on sight. The perks of being the very first believer (Day 1145) are worth the risk. Sure you get called crazy quite a bit, and only half the time does anyone mean the good kind of crazy, but sometimes you get to enjoy being right.

And while success has a thousand fathers and failure is an orphan, I’ll always enjoy the satisfaction of being the very first to take a chance on a long shot no one thought had any business even trying. And well they were wrong. And I was right. Not just right but really fucking right. I backed the long shot dark horse (somewhere around day 950) because my gut told me that the kid had the right stuff. And wow did he.
I only had a dim hint of exactly what we’d be seeing today as the invite said “Watts Next” cohosted by Nvidia and Valar. Clearly a number of us connected the dots because it was packed. The atom would power the compute and we’d get to see it live.

Every existing investor, and quite a few later stage firms, came out to the middle of nowhere to see if these longshots had really done it. And indeed in just three years the impossible became reality. I’ve never felt prouder to be American. And clearly everyone around me felt the same.
This is a win for all of us. The families who gave up time with their loved ones so their loved one could pursue a dream. The policy makers and scientists who did everything in their power to prove we could make nuclear work again. The investors who wrote checks that no one else wanted to write as it was too risky.
And most importantly, it was a win for the team, led by the indomitable spirit of Isaiah Taylor. Their long nights and constant doubt paid off. The road ahead is long but no one is likely to doubt that we are serious contenders anymore.
I always say there was never a doubt in my mind. I had faith. Isaiah joked he had moments of doubts. I say I’m blessed that I got to be that first believer to say “I think you can do it and I’m going to help.”
And whenever he doubted that we’d make it (there are always near death experiences in any startup) it was my privilege to remind him that doing the impossible is just what we humans do.
Like Captain Kirk, I don’t believe in no win scenarios. I hope you consider joining me for more impossible long shots. Because sometimes taking the shot is worth more than anything else you will ever do.
