The most important lessons I’ve learned from building my own startups:
1) Product first, always. If your product is shit your business will be shit. Be a power user of your product, question what could be better. Obsess over the experience.
I hate how much of business is waiting and deciding how frequently you can follow up without being too annoying.
And when someone is willing to come along and move with extreme urgency it’s the best thing in the world.
Just tried out @mercury 's new Real Time Payments. Absolutely insane how fast it is. Our vendors are super pleased. Props to y'all.
Crypto is dead/useless.
1/ Today, we’re launching real-time payments (RTP): instant, always-on money movement, 24/7, weekends and holidays too.
Pay someone at 9pm on a Friday, it lands by 9:01.
Many banks don’t even know US RTP are possible (lots of banks don’t offer it). Its now live on Mercury.
Today, we're sharing our strategic partnership with Crusoe to launch the first nuclear-powered AI factory data center, designed to validate nuclear power’s effectiveness with AI workloads.
Aalo will initially power a Crusoe Spark™ modular data center, running Crusoe Cloud, in 2027 at Idaho National Laboratory.
Looking forward, Aalo and Crusoe intend to deploy Aalo Pods, Aalo’s 50 MWe XMR power plants, at Crusoe data centers by the end of 2029.
The collaboration is already underway at the Idaho National Lab (INL) in direct partnership with the U.S. Department of Energy (DOE).

The CTR at the Aalo-X campus reached criticality on July 4, 2026. Construction is underway on Aalo's second nuclear reactor, a 10 MWe power plant.

You can now order a physical checkbook on your @mercury Business account.
I know, it's 2026 — but checks (or cheques?) are still very much a thing in the US.
Writing your first check is a small milestone for anyone who's ever opened a bank account, and I still remember mine.
Go order yours. It's basically a piece of art.
In January, Fluidstack raised an $830M Series A at a $7.5B valuation, led by Situational Awareness, with participation from world-leading investors.
Fluidstack builds infrastructure for the leading AI labs - our goal is to be the fastest on the planet at deploying hundreds of gigawatts of compute.
As we stand at the event horizon of the singularity, humanity’s best chance is if democracies, with error correcting institutions, free speech, and checks on power, imbue those same principles into superintelligence. Whoever deploys frontier compute infrastructure fastest will decide whether Al expands human freedom or shrinks it.
We are hiring - come join us.
Mercury's new AI feature Command is a great example of AI enhancing the product vs. feeling forced.
1. I can dump in an email + invoice + wire instructions into a single prompt
2. In-chat tailored UI is generated to fill out any missing information.
3. Ability to review everything and approve all in one interface.
The new software wizard.
It’s official: K2 Space is operating the most powerful Hall thrusters currently flying in space. Just a few weeks after the launch of our first test mission, Gravitas, we’ve successfully fired both of our 20kW Hall thruster systems to achieve a new level of electric propulsion power never before seen on orbit for this type of system. We plan to continue raising and lowering our orbit as we gather more data on the thruster performance while continuing our mission in LEO.
This milestone is yet another validation of K2’s approach to building bigger, as more powerful thrusters will enable the MEO, GEO, and deep space missions of the future.
Today @Mercury announces we've raised $200M at $5.2B!
We're growing and profitable for 4 years running... but we're funding what's coming:
We believe it is a new era for ambitious people in America, and the builders of tomorrow are going to build their finances on @mercury
