Proud to co-lead Arda’s $160M Series A alongside @AltimeterCap and @accel. Rebuilding American manufacturing means getting designs into production faster. Arda is already inside every division at @anduriltech, with reconfigurable automated assembly lines next.
Congrats to @bobmcgrewai and the team on today's public launch!
We started Arda in 2025 to speed up American manufacturing. We have spent the last year building with Anduril as our design partner. Today we are launching the company publicly on CNBC and announcing our Series A: $160M at a $1.5B valuation.
Our platform helps manufacturers design and operate manual assembly lines, putting designs into production faster now. Next we'll build automated lines that can be reconfigured as quickly as human workers, letting America make products that now require armies of workers in Asia.

thrilled to co-lead this round with @vkhosla @SStrohband @khoslaventures . @bobmcgrewai is a singular leader, and we in the US could not be more fortunate he’s applying his energy to improving American manufacturing. congratulations!

AI’s impact will reach far beyond the workplace. Tolan is building a companion to help people make sense of daily life and move toward their goals. We’re glad to back the team as they build what personal AI can become.
Last year we launched Tolan, inspired by a vision of AI that sees you and believes in you, not one that books restaurant reservations for you.
Your Tolan shows up for you at 3am when you’re alone with your newborn. On your commute when you’re anxious about the day ahead. When you just finished a new show and none of your friends have watched it yet.
The people who love Tolan are parents. Caregivers. Moms in Dallas and Dads in Atlanta. People who aren’t trying to optimize and be more productive, but who simply want to feel seen and supported in their aspirations.
This month more than 250k people will spend time with their Tolan. Those users have exchanged billions of messages across more than 70m conversations over the last year.
Today, we're announcing $30m in additional capital from @mignano and @usv, with @khoslaventures and @rabois doubling down, bringing our total capital raised to $60m.
To celebrate, we made a short film celebrating some of the ways that Tolans show up :)

Exclusive: Tolan's AI app is used by 250K people, mostly outside of Silicon Valley.
Now the startup has raised $30M from USV, Khosla Ventures and Homebrew to widen access to an AI companion CEO Quinten Farmer (@quintendf) wants you to trust.

If Factory works for one of the most demanding enterprises in then world (scale, security, compliance, sophistication re impact) it will absolutely satisfy your organization’s requirements.
As the world’s largest alternative asset manager, @Blackstone requires the highest standards of deployment flexibility and governance.
Factory made it possible to operate agentic software development within Blackstone’s own data centers without compromising model choice or workflows.

AI can't scale if power can't keep up.
We've long believed that abundant, reliable energy is critical to the future, and that we need fundamentally faster ways to generate and deliver it.
That's why we backed @MainspringEnrgy early. Their modular technology can bring power online far faster than traditional infrastructure.
Today's agreement with AEP is a huge milestone for the team and a sign of just how critical speed to power has become. ⚡

American Electric Power has signed an agreement to buy up to 1.6 gigawatts of small generators from Mainspring Energy to help power the AI boom, in a deal that could amount to more than $4 billion over the next eight years bloomberg.com/news/articles/…

Quantum computing’s promise is enormous. @TeamOratomic is taking on the hard work of making it useful at scale.
Congrats to the team on their Series B as they build a fault-tolerant quantum computer. Thrilled to back this mission!
Oratomic has raised a Series B, bringing our total funding to $775M since our launch in March. We are on a focused mission to build a utility-scale, fault-tolerant quantum computer.

As AI drives content creation costs toward zero, every company can become a studio. Those teams need better tools to manage their work. Shade is building them, with early customer traction to match. Proud to back @bfan1256 and the @tryshadeinc team!
As Q3 has just closed, I wanted to give a huge shout-out to our Shade team on the amazing progress this year — with a full quarter still to go:
• Revenue up more than 6x over the past year
• Signing enormous new logos every week — including leading consumer brands my mom would know such as Motorola, Carnival Cruise Line, and Hello Fresh; top tech companies including Webflow, Snowflake, and Clay; educational and public institutions such as Columbia University and The U.S. Dept. of Commerce; and some of my favorite entertainment brands and sports teams (which unfortunately we cannot name yet)
• Shipped more than anyone in the industry, including launching our custom objects and automations platform that won us NAB Product of the Year
Thanks to everyone! We’ll be announcing a bunch more innovative new product stuff at NAB NY in a few weeks.
Welcome to the KV portfolio, @Arena! As AI gets more powerful, the world needs an independent, data-driven way to measure not just what models can do, but whether they can be trusted.
We’re excited to co-lead Arena’s Series B. Congrats to the team!
Today, we're announcing our Series B: $200M at a $3.1B valuation, and the release of Arena's Alignment Index.
AI is advancing faster than our ability to evaluate it. The world needs a neutral third party to measure how safe and aligned AI actually is once it's in the hands of real people. That's the role Arena is stepping into today.
The Alignment Index is built from real-world agent traces, starting with three signals: Unauthorized Action, False Attribution, and Deceptive Completion, with results for over 20 frontier models launching today.
Hear more from our CEO @ml_angelopoulos below, and read the full breakdown, and more details about our company growth in thread.
This funding will allow us to go further on safety signals, agentic capabilities, and modalities. It will also allow us to grow the company to match the scale of our mission. Today, we’re still a nimble team of 90, and we're looking for people to join us across research, product, engineering, and more. Come build with us.
As AI gets more capable and autonomous, understanding how well it can safely and effectively work for people only matters more. That's what Arena is built to measure and advance.
Thank you to our community, our investors, and everyone building with us!

Through the U.S. Department of @ENERGY's Genesis Mission, fusion energy machines are about to get a lot smarter.
CFS is the only private company leading a Genesis Mission Phase II project, directing a group of American companies, universities, and labs that’ll extend our work applying artificial intelligence and digital twin technology to our SPARC fusion demonstration machine. With decades of publicly funded fusion science data and the might of DOE supercomputers, we’ll be able to put faster AI technology to use. This phase of the Genesis Mission is designed to help expand the impact of projects with a demonstrated potential to benefit from AI and to improve the nation’s scientific capability.
A digital twin is a sophisticated clone of real-world hardware, a 3D representation with two-way communication links that show what’s happening in the tokamak while also helping us control it. Building AI models into this digital twin adds ultrafast AI simulations, giving us new abilities to understand SPARC fusion pulses in just moments. That rapid learning will let us chart the best path to progress so we can deliver fusion energy to the grid as fast as possible.
In effect, AI can serve as a co-pilot to run the machine, and the digital twin gives us a better flight simulator cockpit. DOE supercomputers will help us train AI models validated with data from decades of fusion research, helping to turn hours of plodding computer simulations into immediate insights.
“This project will convert decades of R&D performed across the U.S. fusion community into tools that can be applied to accelerate SPARC operations,” said @BrandonSorbom, Chief Science Officer and Co-founder of CFS. “Together, our team of public and private leaders in AI and fusion will be able to unify and apply decades of U.S. research and tackle some of the fusion industry’s biggest challenges — creating new opportunities to move fusion to the grid faster.”
The group we’re leading on this project also includes laboratories (@Livermore_Lab, @ORNL, @PPPLab, @SLAClab), universities (@CarnegieMellon, @MIT), and private companies (@GoogleDeepMind, @nvidia, @Synopsys, and @GeneralAtomics).
